Electric jack hammer hits poorly. How the jack mechanism looks and works?

Electric jack hammer. the principles of the chipping hammer

Some people think that it was the pneumatic and chip hammer that was the first step in the development of fucking tools, but the real electric chipper were first invented. However, using them in the most relevant direction at that time-mining-was quite dangerous, due to the high risks of ignition from sparks arising inside the unit. Therefore, when pneumatic hammers arose, they for a long time replaced all competitors to the side. Today the situation takes other turns.

Most users are much more important than mobility is not convenience, but they work with hammers in rooms far from ignition risks, or even outside the room. The builders were not utilities began to actively master an electric jack of a hammer, since such a fucking tool works from pulses of the electric motor, which drives the battleship. Dependence on power sources in the premises where repairs is carried out is usually almost invisible, therefore, among the repairmen, it is electric models that use the greatest love, because they are not relatively inexpensive, they are not able to cope with the assigned tasks.

The gasoline chipper in front of electric non.pneumatic tools has a significant one that play slots. it is not tied to source of energy. However, in his arsenal, of course, other shortcomings are not a noise level, not considerable fuel consumption, not toxic exhausts. Therefore, in the room this is not necessary to work, or it is remarkably ventilated. A pneumatic fucking tool is the most reliable not safe among chipsters. He does not spark, is not afraid of moisture, does not need fuel (except for the air of the air), does not pollute the air with exhausts.

The only negative. it is attached to the compressor, which pumps air under pressure. For repairmen, buying such a tool makes sense only when the compressor is already available.

Characteristics

Jurk hammer. a tool designed to destroy a solid surface. The use of Makita chipped equipment allows you to remove the tile, destroy the partition from brick, concrete, remove asphalt, clean the plaster and concrete layer, make niches and holes in the walls, hammer frozen soil and ice, disassemble metal structures.

Any jam of the jaw is characterized by a powerful impact force, for which the boiler, peak, and drive are responsible. The tool is not characterized by a complex internal design, as well as the scheme of work. Inside the electric hammer is a spite that brings the drive into the work. The latter transfers a mechanical impulse to the peak, that is, the shock mechanism. Depending on performance, it weighs from 3 to 32 kilograms.

The task that is facing the chipper is determined by the peculiarity of its executive part. the peak. The latter can be the following varieties:

The main malfunctions of the tool

When drilling holes by the as a pedorator, the main factor is not the rotation of the drill, but the blow. Both the drilling speed and the ability of the tool to cope with especially hard building materials (concrete, granite and others) depends on its strength.

Dust and constant load on the tool negatively affect his work. During operation, the impact force can significantly decrease or disappear completely.

How the peorator works and why he “refuses” to hammer?

The percussion mechanism of the penetrator

Most modern peorators have an electro.pneumatic shock mechanism. “Electro”. because the mechanics are driven by an electric motor, and “pneumatic” means that the battles, which beats the shank of the drill, is driven by air.

  • Gear of rotation from engine
  • “Drunk” bearing
  • Piston
  • Drummer (“Flying Piston”)
  • Trunk
  • Board
  • SDS cartridge

When clicking on the button, the engine transfers rotation of the shaft with a “drunk” bearing, which in turn sets in motion the piston inside the barrel. When the piston moves forward, the air pressure increases between it and the drummer.

The drummer move towards the box and hits it. The fighting transfers the energy of the impact to the drill. Then the piston makes movement in the opposite direction, creating a spare area in the trunk.

Due to this, the drummer returns to its original position, after which the entire cycle is repeated.

Most of the penetrators have two or three operating modes:

  • Combined mode: hit and rotation of the drill;
  • rotation blocking mode: only a shock mechanism works;
  • Shock blocking mode: Peorator can be used as a drill or mixer for preparing building mixtures.

Reasons for the lack of a blow

At first glance, it seems that the shock mechanism has a simple design, and there is nothing to break there. Load, dust and vibration gradually take their. Usually the impact force decreases as the mechanism is worn and eventually comes to naught. A sharp disappearance of the blow is explained by the deformation or destruction of some parts.

The boiler and the drummer

These details are made from high.strength steel. The shock is rarely out of order, but the sleeve in which it moves absorbs part of the shock energy and is destroyed over time. Shards jamming the battleship, and the peoporator stops beating.

Drummer (“Flying Piston”) has a compression ring. With its wear, part of the air passes into the gap between the cylinder in the barrel and the drummer. The more wear, the weaker the blow. The problem solves the replacement of the ring with a new.

Иногда ударная часть «летающего поршня» разбивается о боек. This is usually the result of pressure on the peorator when drilling holes. The drilling rate does not increase, but the load on the mechanism increases, which accelerates wear. Repair consists in removing the chamfer on the emery machine or replacing the part.

“Drunk” bearing

It is planted on the shaft at an angle and sets the piston in motion. In the presence of production or destruction, the bearing must be replaced.

Switch of modes

Details of the mechanism can leave the guide grooves. This may be a consequence of deformation, wear or frequent work with a tool with a not fully included mode. The malfunction is eliminated by installing parts in its place or replacing with new.

Lubrication

Untimely lubrication replacement can also be the reason for the lack of a blow. The work of the as a peorator implies the presence of dust, which does not affect the properties of lubricants in the best way.

Dust can clog holes in the cylinder designed for air circulation when operating a shock mechanism.

The same effect is not excluded when using too thick lubrication, not intended for peorators.

What to do if there is no blow in the penetrator

If the tool refuses to hammer, it is not necessary to immediately disassemble it or plan a trip to the service. Sometimes the reasons for the refusal can be elementary.

In some models of peorators, the impact mode is blocked by a reverse. It is enough to move the lever to the right position. A similar effect may be from the not completely rotated mode switch.

With vertical drilling, dust and small fragments can score a cartridge and a fight under the drill. Having taken out the drill, it is necessary to clean the cartridge of garbage and push the boiler down.

The use of cheap consumables can also cause a malfunction. The shank of a poor.quality drill sometimes turns out to be shazed in the form of a “fungus” inside the cartridge. It is not always possible to extract such a drill without disassembling a cartridge.

High.quality consumables, timely prevention and maintenance are guaranteed to exclude the refusal of the tool at the most inopportune moment. If hints appear for a malfunction, it is better to immediately contact the service or if you have experience to repair yourself.

The device and principle of operation of the penetrator

To understand how to fix the peorator in case of breakdown, you need to know its device and the principle of operation. This tool can work immediately in 3 directions:

  • drill various holes in concrete and brick, like a drill;
  • Touch the grooves in soft plaster, like a jack of a hammer;
  • screw the screws like an electric screwdriver.

Various modirators can differ in some design features and additional functions. However, despite all the differences, such products have the same nodes and systems that allow the to their main function to perform the peorators. Such nodes include:

Pneumatic shock mechanism device diagram.

There are also additional nodes that simplify the operation of the peorator. These include: anti.vibrational system, tool fixation mechanism in a certain position, a device for switching various modes of operation, a system of restriction of drilling depth, etc.

One of the main elements of the penetrator is the shock mechanism that can be electromagnetic or pneumatic type. In the first case, the operation of the shock mechanism is controlled by 2 electromagnetic coils, which create reciprocating movements of the core, and the core transfers these blows to the end part of the tool. In the second case, the operation of the mechanism is ensured thanks to the movement of the piston in the cylinder. It was this type of shock mechanism that was most widespread.

The device of the pneumatic shock mechanism is shown in the rice. 2, where: 1. pumping bearing, 2.Piston, 3. ram, 4. drummer, 5. gear gear. When the tool is turned on, the rotational moment from the electric motor is transmitted to the pumping bearing, which, converting the rotational movement into vibrational, transfers it to the piston. Due to the pressure difference between the ram and the piston, the first begins to move, bringing the buck to work. The buck hit the working element installed in the cartridge. According to this principle, the transformation of electrical energy into an impact is carried out.

The reasons and the possibility of eliminating the problem when there is no penetrator

When drilling holes by the as a pedorator, the main factor is not the rotation of the drill, but the blow. Both the drilling speed and the ability of the tool to cope with especially hard building materials (concrete, granite and others) depends on its strength.

Dust and constant load on the tool negatively affect his work. During operation, the impact force can significantly decrease or disappear completely.

Why the peorator stopped hammering. the main reasons and methods of elimination

The main role is played in the work of the penetrator, not the rotation of the storm mechanism. If the shock force weakens or completely disappears, it becomes impossible to drill the surface with such an instrument. The reasons why the peorator ceased to hammer are related to both the mechanics and the electric part. The article talks about problems and ways to eliminate them.

Device and operation of the shock mechanism

Before talking directly about the causes of malfunctions with the drilling part of the penetrator, it is worth understanding the device of the shock mechanism. It consists of:

  • gears with slanting teeth, which transfers the rotation pulse from the engine to the drill;
  • rolling bearing. He is more known as a drunk bearing;
  • stem piston;
  • flying piston or drummer;
  • The box.

The working cycle itself is repeated according to the same algorithm:

  • Pressing the launch button transfers a rotation pulse from the engine to a gear with oblique cloves.
  • A drunken bearing is located on one shaft with her. He sets the stem piston in motion.
  • Due to this movement between the piston and the drummer, the air pressure increases. It makes the flying piston beat on a brisk.
  • The fight transfers impulse to the stroke to the drilling part.
  • After the stem strike, the piston returns back, the air pressure between it and the drummer weakens. The flying piston also returns to the starting position.

Most of the well.known manufacturers produce peorators with three operating modes:

Reasons for the lack

Determine what is the reason that the peorator hits poorly or does not beat at all, sometimes you can visually. In other cases, the analysis of the mechanical part or motor is required. Now more about common problems.

There is no blow, but rotates

If the pea has stopped hammering, but drill under load and in idle, the causes of the problem may be as follows:

  • The boiler is located in the sleeve. When the tool is working, it has a part of the impulse impulse, which over time leads to deformation or breakdown of the sleeve. The steel turns out to be blocked fragments of the sleeve, jams, and the peorator can no longer hammer.
  • Distance of a compression ring on a drummer. The larger it is, the weaker the power of the blow will be. Output. replacing a compression ring.
  • Damage or complete destruction of the clip of a drunken bearing. It is also subject to change.

  • Calm with switch of operating modes. This is usually due to wear, deformations of the penetrator. The switch leaves the guide grooves. It must be returned to the correct position, and if it is ineffective, put a new.
  • The tool has not been lubricated for a long time oil. Dust clogs all the holes of the cylinders for air penetration, which over time leads to loss of shock power. You can not use too thick lubricants-because of them the peorator will also stop hammering.
  • The clutch couplings were cut off on the intermediate shaft.

Hollows, but does not drill

When the pedulator is normally hollowed, but does not twist, the reasons are as follows:

  • The weakening of the tension of the spring, which crushes the clutch coupling;
  • The gear of the barrel shaft is not fixed with a lock video;
  • Cut the teeth on a small gear rotor. Options. replace either one gear or the whole rotor.

The drilling part stuck in the cartridge

Sometimes you do not need to disassemble the peorator in order to understand why it does not beat. It happens that the drill stuck in the cartridge.

  • When installing the drill on the cartridge on the shank, no grease was applied. It is necessary to gently move the sealing gum on the cartridge and add WD-40 to the connection place.
  • The shank broke. In this case, you must first inject WD-40, and only then try to extract the boat. If it doesn’t work, it is worth disassembleing the cartridge and knock out the boat.
  • The role of the drill is played by a drill with an adapter. Here also first processes the place of connection WD-40. After a few minutes, you can start easily tapped the cartridge with a hammer, with the second hand, systematically shake the drill. After that, the clamping fists of the cartridge should be made up.

Bur flies out of the cartridge

When, while under load, the drilling mechanism falls out of the cartridge, the reason is the development or breakdown of the latter. You need to remove and disassemble the cartridge to determine the source of the problem.

Important! It will not work to work with such an electric screwdriver, besides, the falling drill can injure.

The cartridge flies

If a cartridge breaks down from the pea, the reason in the output ring at the place of attachment of the cartridge to the raster sleeve. The output is simple. replace the ring.

Charges with the electric part

If the pedorator is connected to the network, but when starting, there is either a lack of impact, or lack of torment, or both, the reasons should be sought in the plane of electricians. Typically, these problems are accompanied by the following features:

  • extraneous sounds that are not characteristic of normal work;
  • The motor is buzzing, but the working shaft does not twist;
  • graphite brushes sparkle;
  • Gary’s distinct smell, visible evaporation, black smoke;
  • The case of the penetrator was very warmed up.

The motor is buzzing, but there is no rotation

In this case, the focus of the problem is hidden in the engine gearbox: it does not allow the rotor to spin. If there is no sound, there are more reasons:

The reasons for the breakdown of the penetrator

The principle of operation of the strike mechanism of the peorator.

If the peorator stopped working, the reasons may be as follows:

  • malfunction of a curvature mechanism;
  • development of an intermediate shaft;
  • lack of lubrication;
  • wear of the clamping node;
  • Mechanical damage to shock elements (Cover or clutch clutch).

The peorator must be periodically lubricated, applying special material instead of traditional lithola. Savings on the equipment leads to intensive wear of the barrel, which houses the shank of the bite/drill. Rice. 2

The peorator does not hide after a significant volume of lubrication from the gearbox during wear of the oil seals, rings. Rubber parts work in aggressive environments, extreme conditions. With a significant accumulation of dust and crumbs on their surface, the material loses its elasticity, bursts, cracks from the loads.

The diagram of the device components of the peorator.

Violation of operating modes is dangerous for the peorator:

  • Inexperienced users are too pressed on the case in the chipper mode, forgetting that the chisel works due to the effort of the internal mechanism, the amplitude of the stroke is reduced, leading to its breakdown;
  • a change in the chisel trajectory with a certain buried by the working body into the destroyed material leads to the wear of the piston, a fight, bearings, a curved-shawl node;
  • Overheating of the tool with prolonged use in severe conditions is fraught with a cut of gears.

The peorator is often used to stroke ceilings, which increases the amount of dust in the spindle. External anthers are not able to protect the internal nodes from the penetration of the abrasive. The instruments of two or three manufacturers are equipped with internal anthers (for example, the Kress PK450HM model), therefore, periodic audit is required, cleaning the clamping unit.

The power tool can work in drilling mode without a chipper, but not vice versa. When spoiling the rotation unit, it becomes impossible, since the internal mechanisms are jammed. In this case, urgent repair will cost ½. ¾ the cost of a new tool, which is economically unprofitable for the user.

Replacing the main nodes

If during the diagnosis the master determines that one of the main nodes has become unusable, it will replace it to avoid damage to the rest of the device.

Bearings

To extract a damaged bearing, the master defends the stop ring (if it holds the part), using a specialized puller. The rotational movement along the thread “twists” the old bearing from the shaft. The new part is piled on the shaft with a wooden or rubber “soft” hammer, after which it is lubricated.

Start button

The first thing to do after the device is de.energized is to separate the button from the wiring of the power unit. The wires are then divided and cleaned. New button is bought at the electrical appliance store.

Brushes

If special grooves are provided in the design, which allow you to extract the brushes without unwinding the engine itself. In this case, the master unscrews the clamping springs and fixing screws and turns off the contact wires. After that it pulls old brushes. Before installing new brushes, the channel grooves are recommended to be cleaned with alcohol and dried with a rag.

Cartridge

Repair, cleaning and lubrication of cartridge nodes is easily carried out in a home workshop. However, in the event that one or more details are worn out to a dangerous limit, the cartridge is removed, as described above, and unsuitable details are replaced.

How to fix it with your own hands?

Diagnostics

A mechanical one is easy to determine by eye or by ear. During the work of the hammer, an uncharacteristic rumble is heard or stirring. Sometimes a rattle or knock is clearly published, which is accompanied by a disgusting smell from the body.

The most characteristic mechanical breakdown due to high loads on the equipment lies in excessive exposure to dust, dirt on the tool body. He is subjected to constant inclusion and switching of the operating modes, which is why the entire hammer system suffers.

When the cartridge fails, this is found immediately when the hammer is included in the electric network. This is due to the fact that the details are excessive load, and with constant vibration, a large stream of dust comes. The mechanical failure of the bearing, damage to the gears of gears, clutch couplings and cracks on a spindle clamp are easily recovered manually.

Diagnosis of the electrical part is taking place by identifying the following signs:

  • there is no motor reaction when the device is included in the electrical network;
  • When scrolling, sparks from the brush of the collector are underway;
  • The smell of burning isolation is felt;
  • A stream of thin smoke with a caustic smell is visible from the case.

Dismantling and cleaning

  • The priority task when disassembling the hammer is to twist the lock spring and the peak excavation.
  • Then twisted and put aside the stopping ring on the muffler. For this procedure, you need special tools with a twisting property.
  • Remove the ring on the upper part of the chipper, remove the intermediate link lock, and if possible, the link itself.
  • If during diagnosis the freezing of the barrel channels was found due to moisture, then the pressure of compressed air is first checked. Blow the base with a compressed air stream and with a malfunction replace the sleeve.
  • If it was not possible to eliminate the breakdown by squeezing air, then flushing and cleaning of dirt, hardened water are used and cleaned.
  • When slowed the work of the hammer, the sleeve is disconnected from the network and the hammer, check the indicators of air pressure. The length of the rubber sleeve from the air duct to the hammer should be 10–12 m. If the indicator is exceeded, the excess part of the sleeve is cut or replaced by a suitable size.

If the sleeve is squeezed due to too abundant or, conversely, thick lubrication, you need to disconnect the sleeve. Blow the released sleeve, and rinse and work with a hammer.

The weak shocks of the tool with a loose press of the valve distribution to the end of the barrel are corrected by disconnecting the hammer and removing the muffler. In this case, the locking ring should be moved away and remove the fixer from the equipment.

In order to correctly place these parts and get the required frequency of shocks per unit of time, you need to turn the link to the stop and install the latch so that it falls exactly in the holes of the barrel and the link. If there are extraneous objects between the adjacent details, then they are removed by analyzing the tool to component elements. They are removed from the body by flushing:

After washing, all the details are well poured with air, collect, and then work out.

If you do not succeed in repairing the jack of chipping hammer, then the details that will restore the primary functions of the tool: they use the details:

  • air and fuel filters;
  • egnition lock;
  • brushes of the electric motor collector;
  • oil;
  • spark plug;
  • rotor;
  • stator;
  • cartridge;
  • bearing;
  • cord and fork;
  • winding of the anchor and stator;
  • ring;
  • anther.

The device and principle of operation of the penetrator

To understand how to fix the peorator in case of breakdown, you need to know its device and the principle of operation. This tool can work immediately in 3 directions:

  • drill various holes in concrete and brick, like a drill;
  • Touch the grooves in soft plaster, like a jack of a hammer;
  • screw the screws like an electric screwdriver.

Various modirators can differ in some design features and additional functions. However, despite all the differences, such products have the same nodes and systems that allow the to their main function to perform the peorators. Such nodes include:

Pneumatic shock mechanism device diagram.

There are also additional nodes that simplify the operation of the peorator. These include: anti.vibrational system, tool fixation mechanism in a certain position, a device for switching various modes of operation, a system of restriction of drilling depth, etc.

One of the main elements of the penetrator is the shock mechanism that can be electromagnetic or pneumatic type. In the first case, the operation of the shock mechanism is controlled by 2 electromagnetic coils, which create reciprocating movements of the core, and the core transfers these blows to the end part of the tool. In the second case, the operation of the mechanism is ensured thanks to the movement of the piston in the cylinder. It was this type of shock mechanism that was most widespread.

The device of the pneumatic shock mechanism is shown in the rice. 2, where: 1. pumping bearing, 2.Piston, 3. ram, 4. drummer, 5. gear gear. When the tool is turned on, the rotational moment from the electric motor is transmitted to the pumping bearing, which, converting the rotational movement into vibrational, transfers it to the piston. Due to the pressure difference between the ram and the piston, the first begins to move, bringing the buck to work. The buck hit the working element installed in the cartridge. According to this principle, the transformation of electrical energy into an impact is carried out.

Preventive measures

After we have sorted out the main causes of the malfunction of the penetrator, as well as the methods of repairing breakdowns, you can distinguish several points on how to extend the life of your shock tool.

  • In the case of frequent repair work, cleaning the peorater must be done at least once a month.
  • Do not forget to regularly lubricate the details of the device.
  • To prevent malfunctions, you should choose a high.quality peorator. Cheap devices are suitable only for work a couple of times a year.
  • So that the mechanism does not overheat, and the brushes are not washed, it is worth taking breaks in work. For example, after use for 20-30 minutes, let the pedorator rest 10 minutes.
  • And the last. after you have finished work, do not leave the peorator dirty. Be sure to clean it after each use and put it in a special box.

Following these small advice, you can extend your life to your peorator, which will save you time on its repair and money to buy a new tool.

Do not be afraid to disassemble it, perhaps he stopped working due to a small malfunction that can be solved with your own hands.

Watch how to fix a peorator with your own hands, watch in the next video.

The list of the most common malfunctions of the power tool is invariably mentioned when the BlackDecker, Bosch, Dewalt or any other brand is not working in drilling mode, but the processed material is actively hollowed.

Effective shock impact is an important advantage of the penetrator, but without the rotation of the drill, it will be almost completely leveled. The functionality of the tool will be limited by short.term operations with a donkey, pike, etc.P

Typically, the most simple answer to the question is why, when switching to drill, the peorator hits, as in shock mode. Most likely, this is caused by a breakdown of the mode switch. a rather vulnerable unit of many types of power tools. Replacement or repair of the switch can be made quickly and do not require large financial costs.

Pre.determine why it beats, but does not drill the peorator Makita, Metabo, Interskol, etc., You can sound: if the engine is obviously heard, but there are no rotational movements, then, obviously, the problem lies in the jamming of the gearbox. Sometimes the teeth of the gears occurs. the broken fragments prevent them from turning them.

Also, among the most common reasons why the Elitech, Hammer, Hitachi, Stanley, Ryobi, Skil and other brands stopped drilling out: Specialists of Service Service Service Service Centers are called:

  • wear of the teeth of the protective coupling. in this case, the characteristic sound of the “ratchet” will be heard;
  • abrasion of gears between the engine shaft and the intermediate shaft;
  • weakening of the horseman of the conical spring;
  • Lack of fixation of a large gear shaft.

In any case, the diagnosis will require disassembling the case and the mechanical part of the tool.

Masters of SC “Successful Service Technique” can easily cope with this work, select the necessary spare parts from their own warehouse, will clean, lubricant, preventive verification and adjustment of other nodes. And all this. quickly, at a favorable price and with the provision of a guarantee of quality of services!

Tool device and its mechanism

The functional purpose of the penetrator is determined by its internal device.

The enhanced shock-revolutionary mechanism of the tool is the so-called “swinging bearing” or “crooked connecting rod”, which rotating from the engine, transmit fluctuations to pneumatic pistons (or piston), after which the air pumped up in the pistons pushes the battleship with a nozzle with a nozzle.

The impact force of 17-20 kilojoules and the parallel rotation of the buoy due to the gear gears ensures the entry of a chisel or drill into a high density material. It is necessary to break through through holes or fine holes for electrical wiring or plumbing pipes.

What malfunctions do Bosch peorators have and how to fix them with your own hands

There is nothing eternal. And the most reliable Bosch peorators begin to break over time. But any malfunction can be repaired with your own hands, if you have a detailed guide to carry out repair work. Below we offer you a benefit of detection of malfunctions in Bosch peorators and a methodology for their elimination. The main causes of breakdowns are:

  • inaccurate work with tools;
  • improper storage of the penetrator;
  • Large loads when working on the working bodies when you have beaten or drill;
  • overheating of the tool;
  • long work without a break;
  • non.compliance with the terms of maintenance.

Conditionally malfunctions can be divided into mechanical and electrical.

Next, we will consider the malfunctions on their belonging, dividing into malfunctions by the mechanical and electric part.

Mechanical malfunctions of the Bosch Peorator

When mechanical malfunctions appear in the operation of the tool, an outsider appears, sparking in the collector area is enhanced, the smell of Gary appears, the instrument is excessively warming, its power drops depending on the duration of the work and the impact on the material.

We will consider all the malfunctions on the Bosch 2-26 peorator diagram. The remaining models, such as Bosch 2-20, 2-24, differ in the design of the intermediate shaft, the installation of various drunken bearings.

The peorator stops hammering, but drill

The peoporator does not hammer under load or in idle mode for the following reasons:

  • the rubber rings of the drummer, a box, a piston were worn out;
  • The roller of the rolling bearing collapsed;
  • the cylinder, a strike of the stress mechanism trunk, collapsed;
  • Cut the slips of the clutch mounted on an intermediate shaft;

The pedulator stopped drilling, but hollows

The main reasons for which the peorator is hollowing, but does not drill, this is:

  • The power of the conical spring, pressing the clutch clutch, weakened;
  • The stopping video does not fix the large gear of the shaft of the barrel;
  • does not hold the mechanism for fixing the tool in the barrel;
  • The peorator does not hammer and does not drill.

The main reasons for which the peorator does not hammer or drill are: are:

  • cut teeth on a small gear of the rotor or on a large gear of an intermediate shaft;
  • the pediatrician electric motor does not work;
  • no power supply to the penetrator.

Consider options in which the peorator does not hammer, but drill

Wear of rubber rings on a drummer, boy, piston.

This reason appears gradual, as the rubber rings are worn out. At first, the blow weakens, then disappears in general.

The malfunction is eliminated by replacing these rubber rings with new.

With any repair of peorators, its components, all rubber products are subject to replacement.

Eliminated by fully replacing the rolling bearing.

The cylinder, drummer, a barrel of the trunk of a shock mechanism were destroyed

There are times when the drummer is bitten in the cylinder pos.26, which leads to the destruction of the cylinder and the impossibility of creating air pressure in the trunk of the shock mechanism. And the second reason: the destruction or breakdown of the box pos.28, leading to curvature of the part and the impossibility of transmitting an impulse impulse. Breakage is eliminated by the complete replacement of the failed parts.

Cut the slings of the clutch coupling pos.67 installed on the intermediate shaft

The malfunction is eliminated by the repair of clutch couplings or its complete replacement. When repairing the clutch coupling, worked outluded teeth are recorded. To correct this defect, a round suprafil and drill is used. The coupling is clamped in the hand, and the boys profiles are straightened with a bormashin with the corresponding suprafil. Similarly modify the slots on the intermediate shaft.

The Broat does not hold the mechanism of fixing the tool in the barrel of the penetrator

Bosch pedorators use two types of cartridges: SDS-Plus SDS-MAX. The difference in the design of the fixing mechanism.

The reason is the wear of the antennae of the raster sleeve of the cartridge, which leads to the impossibility of transferring shock impulse to the working tool of the penetrator.

Cut the teeth on a small gear rotor

The gears are twisted with cutting teeth on one of them, more often on a small.

When jaming the working tool and improper operation of the clutch coupling, there is a wear or complete destruction of the gears of the gears on the shaft of the peorator and the intermediate shaft.

In this case, the rotor or large gear of the intermediate shaft changes completely.

The reasons for a non.working electric motor can be:

  • short circuit in the rotor, stature;
  • destruction of coal electric grinders;
  • weakening of the fastening of the brush holders;
  • burnout of the lamella on the rotor manifold;
  • Rotor or stator windings.

Sample of the equipment of equipment

Equipment write.off act. a document compiled by several persons and confirms the fact of writing off the equipment. All organizations are faced with the need to write off old equipment. Computers, office equipment and other property must be disposed of according to the write.off act. The proper write.off requires an expert opinion on the state of equipment, which contains an assessment confirming the impossibility of further use. A specially created commission or invited expert organization draw up an act of technical survey, on the basis of which it is possible to write off fixed assets from the balance sheet and disposal.

Property tax has to be paid for unwritten, but failed or morally outdated equipment. You can write off fixed assets gradually. through depreciation, but there is a shorter way. drawing up an act of write.off equipment. It is recommended to write off material values ​​that:

Every year, the head of the organization must issue an order to appoint a commission to write off fixed assets. The chairman of such a commission is, as a rule, the deputy director, and members of the commission are the chief accountant, economists and engineering workers.

Grounds for writing off equipment

In most cases, fixed assets are subject to write.off in the following cases:

All three circumstances should be present, otherwise the write.off will be illegal.

For example, you can not write off the computer on the grounds that its performance is not enough to work in any program. The equipment remains suitable for programs with a smaller performance, such as a text editor or email. The write.off of the printer will be considered unreasonable if the commission does not have a technical specialist who may confirm that the fixed asset cannot be repaired. Also, there will be no legitimate write.off of equipment without a decision on its disposal.

If the organization does not have a technical service that can competently confirm the inability to restore equipment, you should contact third.party specialists. The list of activities of the invited organization should have an examination of the technical condition of the equipment, a documented level of qualification of specialists for the diagnosis of relevant fixed assets.

With the selected organization, an agreement is concluded with the wording “Carrying out diagnostics of equipment for evaluating repair costs”. If the act of work performed issued by the invited organization will contain a conclusion about the malfunction and the inability to restore equipment, the organization. the owner of the fixed assets will receive sufficient grounds to write off.

To make a reasonable decision on the appropriateness of the restoration of equipment, it follows:

When deciding on the disposal of equipment, an appropriate act should be drawn up with the application of photographs that fix the disassembled (destroyed) object.

Peculiarities

It is customary to highlight two stages of repairing such equipment. During the defect (it is also defect), they find out what exactly failed, and also how great the resource of adaptation. At the second stage, the problem parts are changing. Experts believe that it makes no sense to repair a very worn.out device. It still will not work as much time as it takes to compensate for the efforts and costs of spare parts.

In order to most rarely repair a jaws, you need to systematically check its condition. Maintenance of products is carried out without special equipment, and saves a lot of time. As for spare parts, in the market you can find only a limited assortment of their. It is simply pointless to change many details, as it is more profitable to purchase a new tool. You can buy:

A number of malfunctions can only be eliminated when contacting a specialized service. It must be said that most repair sets can be used for various models and even for products of different companies. Power also does not matter. Important: the cheapest jack hammers made in Asian countries are rarely repaired. They usually refuse them even in the service.

How to repair Makita products

Makita chipsters are most often damaged by piking. There are only two reasons: wear of the locking element or deformation of the part itself. You can fix the problem with your own hands as follows:

  • remove the upper protective cover;
  • take out the stop of the stopper;
  • clean all surfaces and details;
  • take out the oil seal;
  • examine the stopped element;
  • if necessary, change it on a spare.

If everything is in order with a locking element, check the barrel slots. If they have lost a square shape, they change the entire barrel. It is useful to be able to fight with a blockage of a hose. There is nothing complicated in this: all the work comes down to the search for a deformed place and cutting it. But if the hose has shortened to uncomfortable limits, it will need to change it.

Makita pneumatic hammer owners often complain of very frequent blows, each of which is very weak. This problem appears due to the too large gap separating the air receiver from its distributor. As a result, part of the air stream goes to the side. And therefore, the impulse is transmitted only partially. Repair is carried out like this:

  • dismantle the muffler;
  • take out the stop of the stopper;
  • take out the latch;
  • They twist the link until it reaches a “dead” position;
  • collect everything in the reverse order.

If defects occur in parts connecting the valve box with the end of the barrel, the problem is solved even easier. by conventional cleaning.

Now we will analyze the repair of electric chips. The most important component of this repair is the replacement of lubricating oil during the leak or production of the resource. The work is carried out like this:

  • Check if the tool is connected to the network;
  • remove the crank mechanism;
  • extract lubricants;
  • put a new portion (300 grams exactly).

Important: you can’t change lubricating oil during leakage. In such cases, it is necessary to contact a professional repair center. Even if the performance seems to be restored, the safety of using the tool is impossible to guarantee.

This moment is characteristic not only for Makita products, but also for products of other manufacturers. The elimination of the main part of the problems is not difficult to understand is no more complicated than any other technically simple tool.

Daily care and storage

So that the tool has properly served the master for many years, it is recommended during operation:

  • run the device “in idle” before the start of work. If the peorator gives signs of a breakdown, the work is stopped and the diagnosis begins.
  • Having completed the work, take care of the cleanliness of the penetrator. it is important to remember the electrical appliances “do not like” water, clean the cleaning with a vacuum cleaner and a rag.
  • If the pedorator works in the cold or transferred to the room from the street, do not start it immediately. Let the nodes “warm up”, and thaw the lubricant.
  • Tolerate the peorator in a special box or suitcase (usually included) to avoid dust and building debris.

Thus, if objective precautions and the rules of operation of the peorator are observed, it will last a long and without breakdowns. If the nuisance nevertheless happened. the proposed advice of the masters will help determine the essence of the problem and timely eliminate the breakdown.

Preventive measures

It is better to warn the breakdown, so it is better to adhere to the following recommendations.

  • Change grease twice a year.
  • Once every six months a preventive examination of brushes.
  • Each time after work, thorough cleaning.
  • Before work, lubricate the back of the drill or chisel to reduce the load on the battle.

If the peoporator stopped working normally or a breakdown has occurred, read the instructions and carefully examine it. Before you start repairing yourself, really evaluate your capabilities. If you are sure, try to fix it with your own hands, otherwise, if you are in doubt, it is better to contact a specialist. And remember that already official mechanisms are not subject to warranty obligations and they are reluctant to take service centers for repair.
