Reviews about the repair of AL-KO lawn mowers

I recently noticed that the AL-Ko lawn mower began to cut the grass worse and the efficiency of work has decreased. I decided to contact the service center that I found on the Internet. Experts quickly discovered a malfunction. It turned out that the cutting element had become swept away. In general, the repair was performed quickly and imprisoned the knife on modern equipment. I recommend the service, I will contact more.

AL-Ko lawn mower belongs to me for a long time, during the use of use usually there were no troubles. But a week ago the stroke broke, apparently due to mechanical wear. To fix the problem, I visited the service center and ordered the replacement of the damaged element. I note that the spare parts in the workshop are all original, so the repair is carried out as efficiently as possible. The device is completely repaired, now it works fine.

I contacted the service center for repairing garden equipment. I chose the company on the Internet, viewing reviews and recommendations. As a result, he stopped on the lawnie, since she had an excellent reputation and was located near the house. In general, the problem was corrected at the exact set time. A flywheel and some other internal components were replaced in my lawn mower. The workshop employees perform work promptly and efficiently. Also pleased the cost of services. Despite the fact that company spare parts are used to eliminate malfunctions.

He used his lawn mower for several years, no problems were observed. And recently the bearing flew, so I had to contact the service center. I looked for the workshop for a long time, in the end I chose the lawnser on the advice of acquaintances. The device was repaired quickly, a new bearing was installed and now there are no problems with operation. By the way, the cost of services is much lower than similar services, this is an additional plus.

The engine replacement on the lawn mower with a more powerful.

About five years ago I got an old lawn mower from a neighbor. He complained about problems with the motor, and the fact that he developed his resource. I plunged it a little and after which he worked for four years lifting oil. And last summer the engine ordered to live long. The attempt to repair it has ended in failure. There were no spare parts. Buying a new lawn mower for 25000r was strangled by a toad. And I decided to change the engine for a new.In one of the stores, I saw a similar engine, but the seller replied that there were many problems with the replacement, besides, the price was bitten by their price. I climbed the Internet. On the pages of the Sadovaya-Mototehnika site.ru/ found many offers of engines with a vertical shaft. I began to select the motor and contacted the seller Sergey Anatolyevich, who patiently listened to my wishes and gave some tips, which are as follows: 1. Determine the power of the motor (working volume of the cylinder). I came to the conclusion that my engine is 0.156l2. Determine the type of engine. For the lawn mower, it differs in that there is a brake, and the ignition switch associated with it. On engines for walkways, control is different. You can put it, but with a “collective farm”.3. Determine the length, diameter and shaft shape.

Determine the size of the Carter flange. (As a rule, they are the same for engines 0.140-0.170l, but I neglected it) 5. Determine the shape and distance from the gas tank to the box. (here I took a chance, there is the opportunity to file and feed) unfortunately the 0.156l engine was not on sale, and I did not want to buy less power, t.to. You have to mow in a large area, where not only grass, but also a shrub. Therefore, we stopped at the Champion G170-1VK engine Vertical shaft (5.5 liters.With.). In the option for the lawn mower. Sergei Anatolyevich checked everything, the goods were paid and sent to the Code of TC “SDEK” and three days later I received it in complete completeness at the terminal of SDEK. 7400r. per engine (a discount was operating); 500r. delivery to the NECK; 581p. TC for delivery to the terminal.

The installation of the installation had to be removed from the box and adjusted it by Richtezing (dented everything that interfered), in the area of ​​the oil neck

and in the area of ​​the throttle control mechanism

After that, the engine was screwed to the box with 4 M8 bolts, while 3 holes in the box coincided without problems, and the 4th had to be drilled.And after painting and drying the box, a new motor was installed on it.

The lawn mower was covered by three kilograms, so I had to strengthen the handle, welding the lining at the place of attaching it to the box. I also had to make a new hole to shorten the handle, since the “brake” cable turned out to be short.

I had to transfer the stop of the cable shell.

The knife was attached by a bolt of M8, the veneer used the old one, undermining it by about 0.5mm

Successful tests were successful, but then I found fuel flow. Turned out to be weak Chinese spring clamp. I had to replace with a simple.Well, such a mower turned out.

Tools and materials

You may need a set of tools:

• Oil Container container;
• clean, dry rags, napkins or towels;
• end key with the corresponding nest;
• empty plastic containers (household with lids);
• engine oil;
• set of wrenches;
• trumpet;
• sling syringe;
• siphon.

Removing old oil

Extracting old lubrication is one of the most important stages of the process. To make sure you remove a large amount of old oil, you can use three methods.

• Use a siphon. Insert one end of the tube into the hole for the probe, to measure the oil level until it reaches the bottom of the oil tank. Place the other end of the siphon in a constructively strong container that you will specially use for this and future change of grease. Finally, place wooden blocks or other durable material under the wheel of the mowing on the opposite side of the hole for filling. In the lawn mower under the slope, it is easier to remove almost all the oil.
• Remove the oil cork. Depending on the type of gasoline braid, you can remove the oil cork to drain the old grease. Contact the user’s leadership to determine the location of your drain plug and make sure that you have an end wrench of a suitable size for work. By installing the wrench on the plug, remove it. When the oil is completely dragging, you can replace the cork.
• Use such a special device as a syringe for pumping and filling the oil tank. This is very convenient when the hole of the tank is too narrow, and at the same time it is inconvenient or impossible to fill the new oil from the bottle. The syringe can easily pass through the hole to pump out the old waste oil.
• Tilt method. If you do not have access to a tank with butter, you can drain it by tilting the lawn mower to one side. When tilting the lawn mower, set the lid of the flood neck on the container that you use to collect the waste oil. After the correct location, remove the lid of the flood neck and let the clock completely drain. Using this method, you should know exactly what fuel level is in a lawn mower. It is also important to note where the air filter is located, so as not to pollute it with drain oil.

Search for a malfunction

The external inspection of the contacts of the connectors and windings of the electric motor did not reveal deviations. The electrical diagram of the lawn mower can be checked and you can check it using a multimeter. Measuring the resistance of the windings with a multimeter included in the resistance measurement mode did not reveal their cliff or short circuit.

A segment of the cable that goes from the switch to the engine was also checked. When connecting an ohmmeter to its ends and intensive bending, the resistance did not change and was zero. It became obvious that the malfunction is in the junction unit, which was to disassemble.

Many manufacturers of electrical devices to exclude the possibility of independent repair during assembly use screws that can only be tightened. The supporting plane of the beam towards the unscrewing is made at an oblique angle and the screwdriver cannot catch.

In addition, the head of the screw has a slot under a trihedral screwdriver, which in the standard sets of bit I have not met. But this obstacle is easy to get around if you heat the screw using a soldering iron or emitting a suction of a self.tapping screw using a drill and a drill rotating counterclockwise.

The screw warmed up to the softening point of the plastic is easily unscrewed by the sting of a flat screwdriver selected. By the way, you can also unscrew the strongly rusted and cloudy screws and screws. I had to do this more than once when repairing electric kettle. When assembling I replace exclusive screws with self.tapping screws, with a standard head.

The switch cover still holds on two snapping latches, which must be taken to the side through the existing slots in the housing. The location of the latch is shown by arrows.

Repair of the jack of the lawn mowing circuit breaker

First of all, the contacts of the end switch using the multimeter were checked. In the squeezed position of the pusher, the resistance between all his contacts should strive for infinity, and with pressed. it is equally zero. The contacts were in order.

Imitation of the button with a finger and turning the lever showed that with the slightest weakening of pressing to the lever, which can occur when the lawn mower moves along the lawn due to irregularities due to the irregularities of the earth, the button pusher returned to its original position-the lawn mower turned off.

When examining the parts of the circuit breaker, it turned out that the supporting surface of the lever of fixation of the end circuit breaker in the on the turned on the position was worn out. As a result, she could not reliably ensure the operation of the unit in general.

It was just possible to fuse to a worn place with plastic, but it will also be worn out over time. Therefore, it was decided to install a metal lining, which would ensure reliable operation of the lever until the end of operation of the lawn mower.

For the manufacture of the bracket, a copper wire ⌀1 mm was taken and flared up with a hammer on an anvil to a strip of about 0.3 mm thick. You can cut the bracket and from any metal, even tin. Further, the strip is given the form shown in the photo.

The extra part of the wire was bought by nippers and the resulting P-shaped bracket was installed on the worn part of the lever. Further, the bracket was warmed up by an electric soldering iron and with the help of a tweezer is pressed into plastic.

After the restoration, the lever was installed in the housing of the switch unit and its work was checked. The terminal switch was securely fixed even with a slight movement of the turnover lever for turning on.

A segment of the cable coming from the circuit breaker’s assembly to the gas mowing housing, in which the electric motor is installed hardly not fixed and constantly fluctuates during operation. As a result, the conductors often occur in the entrance places. For more reliable operation of the lawn mower, a worn.out cable section was introduced inside the circuit breaker.

The left part of the photograph shows the factory laying cable that is striking, so these are stretched conductors on the cable fastening section and solder to the contacts of the end circuit breaker. On the right in the photo shows a cable after a re.entering in the mount. The cable was fixed in a new way at the entrance to the housing of the lawn mower.

After assembly, the circuit breaker assembly was installed back on the handle of the lawn mower and once again its work was checked without power supply. The switch worked clearly.

The next step, the power cord was connected to the circuit breaker and the work in real conditions was checked by trial mowing of grass. The audit showed that the independent repair of the lawn mower is made efficiently and can be fixed on the body cover.

The effectiveness of the repair was confirmed in practice, on the lawn of several hundred parts of grass and weeds, growing under fruit trees were repeatedly scored over the summer and the switch did not ever turn off spontaneously.

Step.by.step instructions for launch

In order to easily start a lawn mower, it is necessary to familiarize yourself with step.by.step instructions in more detail, but at the same time you also need to take into account the rules for refueling the device with fuel, as well as many other important nuances.

Only gasoline models need a refueling before starting, the engine of which will work incorrectly without correctly selected fuel or will not at all start. Therefore, having studied in more detail the technical characteristics of your device, you must also familiarize yourself with information about the finished fuel or with the preparation of a special mixture with your own hands.

In the latter case, it is necessary to observe the proportions that are specially designed for the correct functioning of the mechanism.

Sometimes synthetic oils are used for this. Such types of fuel mixtures have a lower cost, but practically do not differ in their quality characteristics. 5 liters of gasoline must be used per 100 grams of synthetic oil, so the mixture will have proportions. 1: 50.

Higher cost have mixtures with mineral oils, since they are considered more natural and environmentally friendly, but in terms of technical characteristics they only slightly exceed synthetic options. Proportions when using such materials will be 1: 35, that is, 3.5 liters of gasoline must be used per 100 grams of oil.

There are also options for gasoline lawn mowers, where the fuel tank is located separately from the crankcase for the oil, so there is no need to prepare the mixture.

But regardless of the model and type of fuel tank, refueling should be done the same way-not completely pouring fuel, but leaving 3-4 centimeters to the edge of the tank.

Launch

Depending on the model of the lawn mower, the launch will be made in different ways. Therefore, it is necessary to take this into account and, comparing with individual technical characteristics, proceed to connect the device and engine establishment.

And if with a manual model working according to the principle of ordinary braids for grass, everything is quite simple, then when starting a gasoline model, some difficulties may arise.

A gasoline lawn mower can be opened in two ways. with an unheated or with a heated engine.

Before you start an uninterrupted engine, you need to take care of turning off the ignition and transmission system, as well as scroll through the starting lever or starter motor shaft. After that, you can start starting, acting as follows:

• First you need to turn on the ignition;
• Then it is necessary to close the air damper;
• After that, you can safely start starting the engine.

After starting, you need to install an idling on the device, using the gas lever. Then, using the same lever, you need to transfer the device to work at low speeds, thereby giving the engine the ability to warm up. After that, you can safely begin operation of the lawn mower at full power. It is worth noting that the launch of a device with an unheated engine is permissible, but further operation in this state is undesirable, since this will negatively affect the general state and the functioning of the lawn mower.

Launching a lawn mower with a warmed engine is much easier, since this process does not require preliminary preparation. The actions must be performed in the following sequence:

• The control lever must be transferred to the fuel supply mode at the maximum level;
• Then you need to start the engine;
• After that, you can choose the necessary speed and start work.

These recommendations are suitable for any models, including manual lawn mowers that work on the principle of ordinary braids for grass.

How to launch after winter?

It may not be easy to start a lawn mower after the winter period, since most often devices of this type are stored in sheds where heating is not provided, which means that they are exposed to harsh winter climate, and sometimes sharp temperature changes. Therefore, it is necessary to approach this process wisely and take into account all the important nuances.

For example, the first thing after winter downtime is necessary to check the fuel tank of the device and make sure that it is clean and there is no old fuel. If the tank is not empty, then it should be cleaned before the new dressing. This must be done because adding new fuel to the old, which survived the winter simple, is unsafe for the functioning of the device. Old fuel, under the influence of winter temperature regime, can slightly change its composition, which when mixed with a more fresh composition or even with simple operation can lead to faults.

Common errors

When starting such a technical unit, some problems may arise, and in order to understand why the lawn mower is not launched, it is necessary to identify the causes, and for further work. eliminate them.

The main reason for the non.betrayal when starting the lawn mowel may cover that there is no gasoline in the fuel tank or its number is not enough to work the device. In this case, it is obvious that it is necessary to do. to refuel the tank with fuel, and in order to prevent such a situation, it is necessary to check in advance the presence of gasoline.

Non.compliance with the rules for the preparation of fuel mixtures, as well as the use of poor.quality raw materials in order to save finance can also lead to errors when starting and when working on a lawn mower. The way out in such a situation is simple. it is necessary to carefully choose the finished fuel, as well as carefully observe the proportions with your own preparation of mixtures.

Errors when starting can occur due to the fact that fuel can pour spark plugs. This is due to prolonged exposure to the launch cable with a closed air damper. To prevent this, you must always check it and, if necessary, return to the correct position.

Naturally, in the case of launching the lawn mower when the ignition is turned off, you may fail, since without this the functioning of the device is impossible.

Therefore, immediately after putting the air damper in order, do not forget to turn on the ignition, and only then can you safely start work.

Step 3

Remove the pipe of the oil probe or drain plug on old models. Turn the lawn mower to the side to drain the water in new versions. Place the pallet under the lawn mower and remove the drain plug using the end key for old models without a tube to measure oil level. Give me a click for a few minutes. Turn the fork back.

Put on the working gloves and take the lawn mowing blade. Do not take a pointed part. Hold the blade by removing the central screw using the end key. Click the wooden block between the blade and the deck if the bolt is really stuck and turn the bolt to free it. If it still does not budge, apply a liquid wrench or similar penetrating oil around the blade bolt and let it absorb for 10 minutes before loosening.

Step 4

Remove all contaminants from under the deck. Lubricate all cable connections and inspect the wiring for damage. Use the island to repair the bare wires or, if necessary, solder them in place.

Place the new engine on the deck. Do not forget to turn the engine a little from the holes under the bolts and attach the self.propelled drive shaft to the belt or gears before fixing the engine using bolts. Screw the engine to the deck. Install a self.propelled drive lid in place.

How to make repair of the lawn mower with your own hands?

Those who have land are very familiar with what struggle is weed.

Especially when it often rains and the grass grows not by the day, but by the hour. Earlier, and sometimes even now, this issue was resolved with the help of a good old braid for grass.

But technologies are not standing still and now in this case, assistants such as electric and gasoline lawn mowers help.

The gasoline mower has several significant advantages over electric, such as mobility and lack of danger of electric shock. But there are many drawbacks, for example: high price, a lot of noise, expensive fuel and significant weight.

Electric mowers are cheaper, easier, work on inexpensive energy, and are not difficult to maintain and repair. These advantages become the main reason for their great popularity among buyers of this type of technique.

But despite the pretty good quality, improper operation and a lot of load, they can disable the device. In such cases, you should not immediately carry the device to the repair shop, but try to find and eliminate the cause of the breakdown yourself. over, as mentioned above, electric lawnmands do not have as many nodes and details as gasoline.

The main thing is to have some tools and faith in yourself. In this article, I will just show you how I did my own repair.

AL-KO, the lawn mower of the company, has serious problems in work, namely: the engine stop without load and its strong overheating, was taken as an example. The motor stops, buzzes and start it again, only re.pressing the “Start” button helps. The button has to restart almost every 30 seconds, and with further work and more often.

Of course, you can work, but it is very annoying and gives the feeling that somewhere the problem is. Therefore, I wanted to figure out where?

After the mower was working within an hour, the engine temperature was measured. It was impossible to touch him with a finger. He directly radiated heat. If you continue to pay attention and continue to work on such a mower, an electric motor will inevitably fail.

It is necessary to determine the cause of the motor overheating. To do this, remove the top cover of the case, under which the engine is located and its power chains.

The lid is held on six screws with a hat under a cross screwdriver.

Unscrew these screws and remove the lid. upward.

Having removed it, you can see the impeller, the capacitor, two connectors and the engine itself.

At first glance, no special problems are invisible. The engine winding darkened slightly from the temperature, but so far it is not critical.

To more carefully inspect the capacitor, it is necessary to unscrew the mount and pull it out.

The capacitor of some external damage did not show.

To check it, you need to disconnect the capacitor and feed the engine for a short time. If he did not start and began to buzz, then the capacitor is intact, because the engine was launched with him. Disconnect the power and connect the container connector back to the engine circuit.

Next, try to twist the impeller. It is mounted on the axis of the rotor and rotates rather tight.

And the reason for such severe rotation is a mechanical brake, which for safety stops the engine rotation when the power is turned off.

It looks like a sleeve that moves freely from top to bottom, along the rotor axis.

Когда напряжение на двигатель не подано, эта втулка прижимается верхней частью о крышку, на которой приклеено две резиновые полосы. Thus, the knife is inhibited on the rotor shaft.

When feeding, the brake sleeve under the influence of the magnetic field is drawn to the center of the rotor and provides free move.

With a careful examination, this sleeve with the brake noticed that at the time of turning on the engine, the brake is retracted and gives the shaft free rotation, but after 2-3 seconds it is released again and begins to slow down the motor. This should not be. Hence the stop of the knife during operation and overheating of the engine.

To find out what is the reason for this work, you need to remove and disassemble the engine.

To do this, disconnect the connectors and put the device on the side to get to the clamping screws. Access to them closes a knife with mounting elements.

To remove it, first you need to unscrew the knife bolt (cm. Figure below).

Direction of rotation, like a regular bolt, and not with left thread. That is, unscrew it counterclockwise, and tighten the clock.

The head of the bolt is plastic, so using the key, it must be well planted so as not to “lick” the edge.

After extracting the bolt, the knife and its plastic disk are removed.

Under it is a height sleeve. With its help, you can slightly lower the knife.

Adjustment is carried out by the washers put under the sleeve (see. drawings below).

We remove everything, only the engine shaft and the hexagonal screws of its fasteners remain.

The key for these bolts has a distance between faces of 6 mm. Unscrew them counterclockwise. Removing the last screw, with one hand, hold the engine.

Next, put the mower on the wheels, and clasping the engine with our hands. we raise it.

To disassemble the motor, you need to free tightening studs. We unscrew them all.

Remove the impeller with two screwdrivers.

We proceed to the removal of the back cover. A wooden block and a hammer will help this.

But first you need to mark the position of the covers with something sharp to the engine body.

Put the engine on the side and hit with a hammer, through a wooden gasket, on the rear shaft.

The motor at that moment should hold another person.

We hit until the axis comes out of the bearing to the end.

All pros in one application

Correct men, everyone fixed from 10 a.m. to 19 pm worked. We went to the market, bought materials. I am very pleased, of course, I will turn again.
