Trimmer for grass electric stihl chain lubricant. What needs to be lubricated in a trimmer

STIHL chain lubricant system

One of the fundamental systems of the chainsaw, work without which is impossible, is the system of forced lubrication of the chain of the chain of the chain. It is not a secret for anyone that at the time of operation of the saw there is a friction of the chain on the tire of the chainsaw, which causes its heating and early wear. To soften friction, the chain mechanism must be lubricated all the time.

Chain lubrication system

To supply oil for lubrication of the chain of the chainsaw, the tool uses a special pump, which is dosed, depending on the number of revolutions of the motor, supplies a lubricant to the saw tire.

The system uses oil for lubrication of the chain of the chainsaw, which has high adhesive characteristics, this is necessary for uniformly dispersing the oil around the entire perimeter of the tire and holding on it even with high revolutions of the chain rotation. Oil flows, the output is located in the place where the chain tension bolt is from here from. Let us see more than the oil supply system implemented in modern chainsaws.

The main reasons why STIHL 180 oil does not come of the Stihl MS 180 chainsaw. The chain of chainsaws is not lubricated. We find and eliminate the cause of the Samos.

The first thing that needs to be done after suspicions arose that the oil lubrication does not come, it is to check its feed. Diagnosis of the lubrication system of the chain of the chain of the chainsaw of the chainsaw STIHL MS 180 frequent. You can do this in two ways. The first is described in detail in the instructions for the tool and is that you need to start a chainsaw, add the gas as much as possible and directed towards any obstacle.

Stihl chainsaw does not enter the carburetor gasoline

With a good lubrication system, the oil will fly from the tip of the tire and on the surface, in the direction of which the tire is directed, a strip of oil drops will appear. If there are still violations in the system, the surface will remain clean.

The second way is to remove the tire from the chainsaw and start it. With an increase in the engine speed, at the place of installation of the tire shank, oil will come from the oil channel, if this does not happen, it is necessary to look for the cause of the malfunction.

The device of the lubrication system

Depending on the brand of the chainsaw, the details of the lubricant can differ a little structurally, but their total number and connection scheme remains unchanged.

The main components of the details of the lubrication system are:

    Oil tank located, as a rule, in the engine crankcase.

Directing tires

. STIHL guide tires are optimized in relation to service life, strength and weight.
■ Ideal symmetry due to its symmetrical form of STIHL guide tires can be turned over. Thus, the load is evenly distributed on both longitudinal sides. . ■ The supporting surface of the circuit, hardened by electromagnetic induction due to induction hardening, increases the wear resistance of the entire supporting surface of the chain. The guide tire serves much longer. . ■ A guide asterisk with a closed roller bearing closed structure prevents the penetration of dirt, as a result of which there is no need for additional maintenance. Lubricant introduced into the bearing during the production process is enough for the entire service life.

This system provides less friction and wear and thereby increases the service life of the cutting headset. Thanks to the thin lubricant channels in the leading links, the lubricant falls on the joints and on the working surfaces of the link links. Additionally, in the working links on both parties there are spherical recesses in which adhesive oil accumulates. It serves as a lubricant between leading links and smooth surfaces of the guide tire.

To ensure the best lubrication of the chain, STIHL recommends using stihl saw oils.

The structure of the saw chain

STIHL saw chains are three. links and always constructed according to the same principle. They differ only in the profile of cutting teeth and the parameters of individual links in the chain.

  • Saw chains consist of leading links (1),
  • The saw chain of Stihl can be repaired by connecting links (2), left cutting by replacing individual links of the chain with a dealer of teeth (3) or right cutting teeth (4). Stihl.
  • Pile chains with low return have tubercular leading links (5) and are indicated by the number 3 in the name of the saw chain, for example 36 RS3.

For even, calm work and optimal cutting power, all cutting teeth should have the same length, it is also necessary to observe the angle of sharpening.

Marking to determine the degree of wear

For simplified and professional sharpening and to control wear, almost all saw chains have a marking to determine the degree of wear:

  • Angle of sharpening: marking for the correct angle of sharpening of the upper blade and for the minimum tooth length: if this marking is achieved during subsequent sharpening, then the saw chain must be replaced.
  • Front angle: marking for the correct angle of the end of the tooth and for the minimum tooth length.
  • Depth limiter: labeling the correct angle of the depth and degree of wear limiter. The restoration of the depth limiter should occur in parallel to this marking.
  • Base of tooth: control marking for wear of the working surface of cutting teeth (tooth base). Uniform wear (parallel to labeling) denotes a normal working wear.

An important advantage of the saw chain with tubercular teeth is the ability to grind them with a round file.

The exception is sawing chains reinforced with solid alloys, marked with STIHL designation Duro. They have special wear resistance and, due to extremely solid blades, are pulled by diamond discs.

All other saw chains are relatively easily dragged using correctly selected tools and sharpening technologies.

Even the best saw chain wears out over time and dulls. If there are problems listed in the following points, then this means that the time has come to sharpen the saw chain:

■ the saw chain does not crash into the tree itself, for cutting it must be influenced by pressing on the motor unit.

■ Instead of rough chips with a transverse cut, the saw chain creates small sawdust.

■ the appearance of smoke during sawing, despite the impeccable lubrication of the chain and the correct tension of the chain.

■ Drizes in one direction. This indicates the cutting teeth that are blown on one side or cutting teeth of unequal length.

■ When sawing, the chain in the cut “beats” and “jumps”. In this case, it is necessary to check the distances of the depth limiters.

■ Enter an indicative tooth in the sharpening zone and then turn on the circuit brake.

■ To move the saw chain, turn off the circuit brake and install it again before sharpening the next tooth.

The basic principles of sharpening the saw chain

The diameter of a round file should be selected depending on the step of the saw chain.

■ Step marking is indicated on the outer wall of the depth limiter.

■ The size of the chain step can be found in the following table.

Marking on the depth limiter . Alternative marking on the depth limiter . Chain step (inch) . Round file ⌀
one 1/4 1/4 4.0 mm
2 325 325 4.8 mm
3 3/8 3/8 5.2 mm
four 404 404 5.8 mm
6 R, RM 3/8 picco 4.0 mm
7 1/4 picco 3.2 mm

Each chain step corresponds to a certain diameter of a round file. (Use only files for saw chains. STIHL dealers will offer you a large selection of appropriate high.quality files).

■ The file is firmly held with one hand by the handle, and with the other hand it is directed directly to the cutting tooth. ■ Start with an approximate tooth and insert the file in the gap between cutting teeth so that you can lead them with pressure along the cutting tooth. . ■ Sharpically sharpen at an angle of 90 ° to the guide tire. ■ The file grinds only when moving forward. When driving back, the file should be raised. ■ File regularly through certain intervals of the time of unilateral wear should be slightly rotated. . ■ STIHL saw chains according to the requirements of the standard are sharpened at an angle of 30 °. parallel to marking the angle of sharpening. . ■ Work as a file so that 1/4 of the diameter of the file protrudes above the upper facet of the cutting tooth.

Preparation of fuel mixture for two.stroke engines

The video shows how to make a fuel mixture for two.stroke engines. Refueling mtocos, chainsaws and.

General recommendations for the preparation of the fuel mixture for 2-stroke engines of the chainsaw, motorcycles and other.

The appearance of additional properties contributes to the use of additives that are in the composition of the oil in the amount of 5-15%. These are additives that create anti.corrosion, anti.symbolic and frost.resistant properties of oils.

The wrong oil composition can ruin the engine, forming a precipitate in the cylinders, lead to coking and rapid engine wear.

It is important to know how much oil you need to add to the gasoline for motorcycles. First of all, you must study the instructions and withstand the recommended proportions. The use of a composition taking into account the model and engine configuration, climatic conditions and load will extend the service life of a gasoline pump. Experienced users advise, buying a tool, immediately buy recommended oil in reserve.

Fuel mixture requirements for a two.stroke engine

The difference between a two.stroke engine in increased power compared to a four.stroke engine. it is prepared in a certain ratio of gasoline and special oil. What is the relationship of oil and gasoline for gasoline pumps is optimal, indicated in the instructions. Recommended proportions must be observed accurately. When adding additives, the manufacturer took into account the type of engine. Therefore, mixing of various oils is prohibited.

Best way to clean lawn care handheld equipments

Using mineral oils, mixing occurs in a proportion of 1:25, 1:30, 1:35. For synthetic oils, use a ratio of 1:50 or 1:80. This means that in each of the proposed mixtures the required amount of oil dissolves in the volume of gasoline. Mixing gasoline with oil for gasoline can be like water with syrup. It is necessary to fill in gasoline, add the exact amount of oil and shake the mixture. It is advisable to use a new solution to work. When stored for more than 2 weeks, the composition changes, and the oil film causes a violation of the carburetor operation.

To dilute and store the combustible mixture, you cannot use PET but. Gasoline destroys plastic, polymer dissolves in the fuel mixture and further worsens the quality of the fuel, creating the danger of the appearance of stray currents.

Reducer of the lawn mower.How to lubricate and how easy to determine that it needs to be lubricated.

What to do with the gearbox of the lawn mower, so that it has served for many years.

Check. Is there a lubricant on your shafts gas. Most likely there is dry!

However, gasoline models of trimmers, it happens, fail. This can happen for various reasons, quite often due to improper maintenance of the device.

Remember that gasoline trimmers for grass need periodic cleaning of the fuel tank and oil replacement.

Trimmer lubrication and its use

In order for the gasoline or electric trimmer for the grass to serve for a long time, and its work was as reliable as possible, it is necessary to perform periodic maintenance of individual elements. The care process does not take much time, includes lubricating the rubbing parts and cleaning the filter.

The gearbox and shaft are most susceptible to wear, for which a special lubricant is intended. It is on sale in most stores of garden equipment and tools.

The gearbox includes a crankcase with many gears that intensively interact with each other, transmitting the torque.

Lubricants reduce friction, so the wear of the parts is significantly reduced. To add the composition to the gearbox, you need to unscrew a special bolt on the housing, and then squeeze the contents of the tube inward until the entire space is filled completely.

For the production of trimmer lubrication, special ingredients are used, which meet the most stringent environmental standards and decompose in the environment after use, without damaging it.

The consistency of increased viscosity during heating decreases in density, so reliably protects the clutches at maximum temperatures.

The frequency of a change in the substance on average is about 50 hours of the general work of the apparatus, more accurate data of a particular model are indicated in its technical passport.

In addition to the gearbox, a trimmer shaft for grass needs care. It should be abundantly lubricated immediately after the purchase (if the manufacturer has not provided for this), and before that it is well cleaned.

In addition, all the joints of the rubbing parts are recommended for lubrication. The transition from the motor to the flexible shaft and the junction of the shaft with the rotating head. This significantly increases the reliability of work and the life of motorcycles.

So that the owner of a trimmer for grass can save on the purchase of individual lubricants for the shaft and gearbox, manufacturers develop universal products that are suitable for all parts immediately.

It is worth noting that not only powerful gasoline trimmers for the grass need mandatory maintenance. Electric models also significantly extend their service, if they are lubricated before seasonal use and after its end.

Time and procedure for preventing transmission.

I recommend that immediately after the purchase, conduct maintenance of a new gas trimmer for grass with the addition of oil to the gearbox. Despite the high cost of garden equipment, some manufacturers save and use oil only at least at the time of the breakdown.

How often to clean a gearbox.

Often a planned verification of the transmission with the addition of liquid oil is carried out once a year at the beginning or at the end of the season. If you do not use a gas trimmer for grass in professional volumes, this is enough.

With large volumes of the mowing, it is necessary to lubricate the gearbox with a brush every 20-50 hours of operation. If the working conditions of garden equipment are difficult, for example, a large field is immediately mowing, and the bushores does not have time to cool, or cheap oils are used, the oil should be checked and added every 20 hours. Operations.

Indirect evidence that the gearbox must be lubricated, there may be overheating or increased noise of the unit. In these cases, if during the verification it turns out that there is enough oil in the composition, I recommend completely replacing it, and it is advisable to choose another car manufacturer for car care products. Also, with a complete change of oil, with disassembly and a sink of the unit, I recommend buying a gasoline trimmer for grass.

Lubrication for gearboxes of a gas trimmer for grass.

Assortment of lubricants for garden technology

According to the instructions, a special transmission fluid must be used to grease the conical wheel wheel. As a rule, manufacturers of garden equipment produce and recommend the chemistry of their brand as the most adapted to their devices.

At the same time, in order to reduce the cost of garden equipment and increase the attractiveness of the brand of auto chemicals, lubrication for garden equipment is usually produced by a multifunctional. It is intended not only to lubricate the gearbox of gasoline trimmers, but also for the processing of hoses, gears and gearboxes of any garden equipment and mechanical devices operating in heavy loads.

Read chain of the video is not lubricated

Even if a special lubricant for gearboxes was almost completely developed during operation, additives nevertheless create an effective lubricant protective film on the surface of the gears.

It should be noted that many owners of mowers in the countries of the former CIS use ordinary oil based on lithium-24 or lithium to lubricate the gearbox. It is convenient to fill the gearbox with a medical syringe of 5 cubic meters. Many motorists, instead of a side screw, pick up threads and wound fatty fittings from cars that served their intersections. This clarification allows you to add Litol without disassembling the node using a syringe for lubrication.

The undoubted advantage of using Litol and luxury.based lubricant for refueling a bushrer is a cheaper operation. But there are nuances that make spears break on the forums of gardeners on the Internet. My thoughts about what can be lubricated with lithium.based oils and what is not, read in the article “Litol as a lubricant for a mowing gearbox”.

Unscrew the side screw on the gears. Depending on the manufacturer of the garden tool, you can use a turnkey bolt instead of a bolt with a hexagonal head, usually up to 17. The thread is normal, unscrew it counterclockwise. Do not lose the sealing puck.

DIY lubrication for corner grinder lubricant for gear of corner grinders consists of the base and diluent. The basis of homemade lubrication is usually a cheer with molybdenum disulfide or cyatim-221. They have a second viscosity in NLGI, therefore, for use in the gearbox of an angle grinding machine, the basis must be diluted. As a diluent, it is best to use simple mineral industrial oil, which, for example, is I-20 oil. To obtain viscosity NLGI 0, you will need to mix approximately 70 percent of the base and 30 percent of the diluent. The resulting mixture is thoroughly mixed and ready for application to the gears and bearings angular grinder.

Timely maintenance of any electric tool is the key to long.term and reliable work. A correctly working tool is also a guarantee of security for a person who uses it. Taking advantage of the tips above, everyone can choose the right lubricant for the gearbox angular grinder and replace it, without resorting to the help of expensive service centers for servicing power tools.

Oil selection rules

The main requirement for the chain is high adhesion. This indicator characterizes the degree of adhesion of the lubricant with the surface of the tire.

trimmer, grass, electric, stihl

During operation of the device, the circuit moves at high speed. If you use low adhesion oil, then during operation it will be scattered by inertia.

The chain during operation can be heavily heated, due to which the metal becomes soft and less wear.resistant. That is why the oil, among other things, should have a good lubricant.

Liquid with foreign impurities or particles of garbage (working out) can disable the oil pump, so it is not recommended to use it.

Oils for chainsaw stihl

One of the most popular oil manufacturers for chains of chainsaws is STIHL. It offers a whole line of products intended for various operation temperatures.

Forest Plus mineral oil is recommended for use at temperatures to.15 ° C. The shelf life of this fluid, subject to storage conditions, is 3 years. The fluid is supplied in liter or five.liter cans.

BIO Plus on a plant.based has the same temperature limit. A feature of the oil is its biological safety, t.the ability to quickly decompose when it enters the soil.

Semi.synthetic fluid Synth Plus is characterized by the ability to maintain working characteristics at temperatures to.25 ° C.

The STIHL chain lubricant system consists of:

All STIHL oils are suitable for long.term lubrication of the saw chain and guide tire.

The supply of lubricating fluid is carried out using a pump with a special adjustment. The chain is lubricated continuously.

During the operation of the tool, the oil leaves the tire groove and immediately absorbed into the sawdust.

Low price category models are equipped with a manual pump operating through the effect of the drive on the handle.

Lubricant malfunctions and how they are eliminated

The main malfunctions of the oil supply system on the chainsaw can be divided into two main types, these are general malfunctions inherent in all chainsaws and individual, which may vary depending on the type of pump and worm transmission installed on a specific model. Let’s start understanding the faults in order.

The work of the chainsaw, if the lubrication of the chain of the chainsaw is not carried out, is prohibited. This adversely affects the tire, the leading star and the chain, and can also result in serious repair costs.

Signs of malfunction of the lubricant system, checking its performance

  • The chain of the chainsaws is dry and has a pale tint without shine.
  • The circuit is relatively quickly stretched.
  • The tire is very hot and can even partially melt paint.
  • The tank oil is practically not reduced.
  • The effectiveness of the cut on a sharp chain has decreased

All these signs indicate that the lubricant proceeds with violations. In order to check the supply of oil with a lubricant system, it is necessary to remove the side tire of the chainsaw and start it. Next, you need to slightly increase the speed observing the end of the oil line. If the oil comes, most likely its amount is not enough for normal lubrication and you need to clean or replace the filter and, if possible, adjust the feed. In the case when it does not act, the problem is more serious and requires further diagnosis.

There is a method of checking the oil supply without removing the tire. To do this, it is necessary to direct the end of the tire to the side, for example, a freshly sawn chock from the cut side and maximize the speed, while you need to try to keep the end of the tire at a distance of not more than 10 cm from the chock. If oil spots begin to appear on its surface, then the oil is supplied.

Search for a malfunction

After it was determined that the oil is not supplied, further diagnosis is possible only if you completely remove the oil system. Of course, in some situations the filter replacement helps, but it is very rare.

Access to the oil pump of some models drank, it is possible only after complete disassembly, respectively, having no skills in repairing a benzo tool, it is better to entrust the repair to professionals.

The most common malfunctions

  • Oil hose cliff. It can sometimes be found during visual inspection. The problem is solved by the replacement of a faulty part.
  • Lack of thread on the shaft of an oil pump, its replacement will help.
  • Defective thread on the lead gear of the pump is similarly solved by the installation of a new part.
  • The absence of a main shaft rogue (relevant for some tools of tools, for example, Homelite). You can fix it instead of a native corkscrew, suitable for the diameter of the carnation, cutting it to the required length.
  • Zoror in the highway. Can be removed by purging with compressed air or mechanically, using a wire of a suitable diameter.
  • Blocking the filter element.
  • The STIHL MS 180 tool, whose pump is unlimited, it often clogs. You can try to rinse in pure gasoline if it does not help replace.
  • In Chinese chainsaws (gypsies), very often cuts the grooves on the main gear through which the effort from the star is transmitted to it.

Individual malfunction of the STIHL MS 180 lubricant system

Due to the fact that the Stihl MS 180 is one of the most common models of chainsaws, I would like to dwell on one malfunction inherent only to it and describe the method of elimination without replacing details.

Quite often on the Stihl MS 180 chainsaw, depressurization of the oil line is observed in the place where the oil pipeline coming from the tank is installed in the saw case. You can determine the malfunction by characteristic lubricant leaks on the bottom of the tool.

To eliminate the malfunction, it is necessary to remove the chainsaw handle, remove the hose from the landing hole, clean and degrease. After all these manipulations, apply a sealant to the hose and install a chainsaw in the housing.

You can find out more about eliminating the malfunction and complete diagnosis of the STIHL chainsaw system by watching a video in which the process of disassembling and repair of the lubrication system is stepped step by step.

What lubricant should be used for a trimmer gearbox for grass?

In the process of work, the mechanical part of the trimmer for grass is loaded with contact efforts on the teeth, resistance reactions from adhering grass (sometimes with dirt), dynamic, shock loads due to a constantly changing torque. The lubricant for the gearbox of the trimmer for the grass should fully consider these features, so the selection of the brand should be strictly individual.

The following factors are taken into account:

  • Manufacturer’s brand. Each trademark is not unreasonably focused on lubricants of its own manufacture (you can talk about cheap Chinese products later). This applies to manufacturers such as Husqvarna, Stihl, Huter, Makita, etc. The exception is trimmers for domestic grass: for example, the caliber in the user’s instructions does not indicate a lubrication brand at all.
  • Break of lubrication. As you know, all lubricants are divided into three groups. high.speed (colloidal systems containing various additives), plastic compounds of universal use and hard lubricants softening during operation.
  • Good adhesion to the surface of the parts of the gearbox, as a result of which the lubricant is not squeezed into the gaps or outside the node.
  • The intensity of lubrication consumption by the gearbox. Here you have to focus on their own experience and recommendations of specialists, since some manufacturers of trimmers, hoping for their own service centers, do not give clear recommendations at all regarding the period of the reducer between two lubricants.

The consumption of the lubricant also depends on the temperature at which it retains its lubricant. When heating the gearbox to 40 ° C, it is believed that its working conditions are satisfactory, and there are enough lubricants.

It is believed that there is no universal lubricant for the gearbox for grass, but this is not entirely. In fact, a suitable lubricant will be the one in which the following components are present:

  • Anti.sympathetic supplements, which include toxic lead;
  • Solid lubricants with the presence of graphite or disulfide of molybdenum (the latter is preferable, since the lubricant is completely preserved for the large range of the speed of the shaft);
  • Only mineral (inorganic!) oils, with a high degree of cleaning.

The mentioned requirements are fully met by Gear Grease Oregon or Champion EP-0, domestic compositions Oleo-Mas, Litol.24, or Ammol 158, as well as those recommended by the manufacturer of a particular model of a trimmer for grass.

How to lubricate the gearbox of a trimmer for grass?

In the upper part of the case, where the gear unit is installed, there is a technological hole that, when operating the trimmer for the grass, is drowned out with a screw. This screw is twisted, and 1.5 2 ml of grease is introduced into the hole using a nose available on a tube. If the lubricant was purchased in another packaging, then a regular disposable medical syringe is suitable for this operation.

After that, the screw is installed in its former place. This procedure, regardless of the user’s recommendations, should be performed every 10 15 hours of operation of a trimmer for grass in working mode. Other reasons for updating or replacing the reducer lubrication are the independent performing of small regulatory work (for example, cleaning and washing the gear of the gearbox before the start of the summer season), repair of the node, preserving the trimmer for grass for the winter period, etc. D.

If the reducer node is disassembled, it is recommended to completely remove the remaining lubricants from the surface of the parts, even if it does not have traces of oxidation and pollution. And only then apply a new grease. After applying the lubricant, it is recommended to handle the shaft several times manually, and make sure that the grease is evenly distributed over all the details of the gearbox.
