Grass trimmer maintenance features

Grass trimmer has received recognition from lovers of well-groomed lawns and lawns. But any technique in itself requires a lot of care. Is it possible to carry out maintenance of the trimmer with your own hands? It turns out, yes, users can even make small repairs of equipment.

Proper fuel mixture preparation

For the petrol mowers, what the user "feeds" her is very important. In this case, the fuel mixture involves the combination of oil and gasoline - for each of these components are certain requirements.

Only high quality oil should be used. two stroke varietiescreated for vehicles with high revs work. There is a taboo on motorcycle products and those designed for water equipment - in both cases it will not be enough to lubricate the parts. Stihl, Champion and Husqvarna are well established.

Any clean one will do. high octane gasoline (from 92 onwards, with a density of not less than 750 and not more than 770 kg / m3). Such a product should not be stored in metal containers, it should not contain impurities and additives. The storage period should not be more than a month.

The fuel mixture is prepared in a ratio of 20 ml / cm3 of oil per liter of gasoline. However, for the first five tanks making the device, it is necessary to prepare it in the ratio of 40 ml / cm3 for the same amount of gasoline, then switch to the indicated figures.

It is best to prepare the mixture in a plastic bottle, but do not store it for more than a couple of weeks.

Stir the mixture thoroughly before filling. Pay attention to the color - if from aquamarine it turned into dark brown, then it is impossible to use such a metamorphosis.

Engine run-in recommendations

It should not immediately, by pouring the mixture, go into a difficult battle with dense vegetation. It is necessary to start with running-in, which will help moving moving parts to each other and strengthen the skills of working with the device.

1. Do not immediately start the engine at maximum speed. It is best to stay at the maximum torque.
2. Overheating is not allowed. However, it is also impossible to mow on a cold engine!
3. The engine must not be overloaded. The throttle should be open for 2/3 of the course.
4. After running in the oil is drained.

These rules will allow increased lubrication of parts of the piston group, which will be a guarantee of long work of the entire device.

How to properly service motokosa

The device consists of the following mandatory elements:

• engine;
• cutting discs;
• fishing line (trim heads);
• angle gear;
• protective covers.

Care trimmer involves monitoring the technical condition of each of them.

Engine care

When caring for a gasoline engine should pay special attention to the cleanliness of the air filter - it should not be sawdust and dirt. Foam filter must be constantly wetted with oil.Inspection should be carried out weekly, promptly change the filter as needed. Before each job, check how nuts and screws are tightened. It is also necessary to clean the silencer and plugs from soot as they are polluted.

In the electric version, it is enough to observe the operating time prescribed by the manufacturer.

Serving blades

If we talk about drives, then you should focus on how carefully sharpened edges of blades. Sharpening must be carried out correctly, otherwise such a disk will load the motor, which will only reduce the resource of the latter. A regular 180 ° flip of double-sided discs should be carried out for even wear.

Line health monitoring

How to care for the cord part? The most important thing in this business is the use of a specially designed cutting line.

In no case can not replace the line with metal cables or wire - this is traumatic.

Other recommendations:

• fishing line must be periodically changed;
• set the diameter specified by the manufacturer;
• cord winding goes tightly, but without crossing the turns;
• the head must be constantly cleaned of dirt and regularly lubricated;
• closely monitor the degree of deterioration (otherwise, the gearbox or shaft is deformed).

How to follow the angle gear

The user's primary task is to prevent dirt from accumulating on it. This circumstance will not allow the part to cool properly. The second requirement is to apply grease (like Husqvarna or something like) designed for a gearbox pair. An annual lubrication procedure is usually sufficient.

What you need to know about shrouds for protection

It is forbidden to work without a protective casing - amateur can be dangerous for the user and others.. But it’s impossible to select such details from among the non-firm ones; use recommended by the manufacturer. Damaged cover should be replaced in a timely manner.

Casing can be fastened both on the rod and on the gearbox. In the universal models (working with both the line and the disc) two different cohojs are attached. On the "forest" can also be located a special cutting plate, which cuts off the excess cord.

We summarize the main points of care in this maintenance video for Hitachi brand mowers:

Repair minor breakdowns

Minor repairs can be done by almost any person.In the electric motor, the user can only check the contacts or replace the brushes. Very much of the elements of the chip can not be repaired without service intervention.

In order to prevent the breakdown of the gasoline engine, it is necessary to blow capacity through the air before injecting new portions of the mixture - this measure will remove the exhaust gases. Four-stroke engines are not recommended to tilt too much: oil supply to parts may stop, which will damage the engine.

If the trimmer motor is broken, and the user does not have knowledge in the field of electrical engineering, then it would be best not to try to disassemble it, but to turn to specialists.

But with such minor breakdowns you can handle with your own hands.

1. At tumbling power switch You can independently replace it with a new one. True, this will require knowledge of the fundamentals of electrical engineering and the ability to work with a soldering iron.
   

2. When dropped from the mowing head wire stop will help flexible wire (copper or aluminum). You can also make a new mount stainless steel.
3. Torn fishing line really replace yourself.To do this, you can choose a nylon or nylon material, from 0.9 to 1.5 mm in diameter (it’s best to know in advance). The drum is disassembled by hand, the fishing line is wound, after which it can be assembled.
   
4. Broken barbell too easy to fasten to the brackets or rails.
5. With strong vibration, the motokosa should be lubricated.
6. Plastic knives are better to replace with metal (stainless steel). They can be attached to the shaft with a sleeve and washer. This "transformation" will allow even mowed grass to mow.
   
7. If a engine does not start, it is necessary to do the following - close the damper for a short time to enrich the mixture. You can also try changing the mix. Then it remains to check whether the gasoline is coming in and, if necessary, to clean it (or even replace the glow plug).

Recommendations for the extension of service

In order to avoid situations with repair, it is best to try to prevent them. To do this, you should focus on such recommendations.

1. To extend the service life semi-automatic coil, it should be pulled out manually more often. Try not to hit the part on the ground.
2. You can not work household oblique for a long time. In electric this moment will be noticeable by the heated casing.But at first it is impossible to overload the motor and the gasoline counterpart. The disk should be put only after spending one volume of the tank.
3. Untimely cleaning can lead to an excess of moisture (electric motor suffers) or clogging (gasoline version loses power).

If you approach the technique with a careful attitude, it will last much longer. And having noticed the signs of wear of parts, it is enough to change them in time, which will prevent more serious damage.
