Trimmer care for grass: Rules and recommendations

A beautiful well.groomed lawn, a neatly trimmed lawn. this is the result of using a trimmer for grass for grass. Using this tool, you can quickly put the site in order. Unlike the lawn mower, a small and maneuverable tool easily penetrates into places (around trees, near the fence, benches). Like any other technique, a trimmer for grass needs competent care and maintenance.

The service life of the lawn mower depends on whether the user complies with the operating rules. All the information that may be required to the owner is posted in the leadership. Be sure to study this document before starting working with a trimmer. And in this article we will dwell on the consideration of the main issues regarding the use of the tool.

Preparation of gasoline-oil mixture

Most trimmers are equipped with two-stroke engines that work on a fuel mixture oil. To prepare it, gasoline with a suitable octane number and 2t oil should be used. It is necessary to observe the proportions specified in the leadership.

The mixture should be fresh, so do not cook with a margin and store it for a long time. In no case do not use car oil, as it contains additives that can lead to breakdown of the trimmer motor for grass. It is best to buy branded oils of famous manufacturers. As for the fuel, the AI-92 and AI-95 brands are suitable.

Gasoline braid device device

The weight of the entire device is about 8 kg, which is quite difficult to hold on the hands. Therefore, the unloading belt-rug belt with a protective pad and regulators is included with the scope of the scythe.

The grass braid is designed for mowing grass and small shrub in personal plots.

As you know, grass can be mowed in different ways. folding it in rolls or simply rolling it out. In addition, the grass is different. soft or rough, with thick stems, shrub.

Choose a suitable nozzle

In addition to its product, the manufacturer usually provides several mills (usually 3).

To work with soft grass as a cutting element, a fishing line for a trimmer is used, wound on a drum. Speed ​​of 9,000 revolutions per minute allows you to quickly process even a large lawn.

For more rough grass and thickets, one of the metal knives can be used, which differ among themselves by the number of cutting teeth.

For mowing thick shoots, reeds, young shrubs, a disk with 40 or 80 teeth is designed. Corn, dry weeds with thick stems, you can mow three- and four-lobed milling.

And in order to put beveled grass in the rolls, a knife with 8 blades is used and a special crest is attached to the braid itself.

And now more about how to install a cutter. The place of fastening of the cutter is called a gearbox. On it, first you need to fix the figure washer using a hexagonal key.

Then put on a knife, combining the holes in it with a protrusion of the puck. After that, you need to install the upper figure washer on the shaft and tighten everything with a nut.

Here you should pay attention to the fact that the thread on the shaft is left, so you need to tighten the nut (like screwing the mowing head) counterclockwise.

To squeeze the nut to the stop will help the key, which is also in the delivery kit. You can replace the cutter by doing all the operations in the reverse order.

How to fix a disk or a fishing line for a trimmer on a trimmer

The cutting mill is attached to the executive organ. The mounting location is called a gearbox. It is not difficult to cope with the task of installing a disk or coil. The principle of consolidating cutting discs on the trimmer is as follows:

  • The figured washer is originally fixed by using a hexagonal key
  • On the shaft set the disk
  • Then install the upper washer, and then tighten it by means of the fastener
  • It is necessary to rotate the nut through a special end key, which is usually equipped with each tool
  • The rotation of the nut is carried out in the direction counterclockwise
  • When rotating, it is necessary to jam the shaft with a hexagonal key

In the opposite sequence, the disk on the trimmer is removed and replaced. details on how to install a coil with a fishing line on a lawn mower is described in this material.

Gasoline gas mowing gasoline with butter

Before mowing grass with a benzo.leggos, it is necessary to season the tool with fuel. As fuel, gasoline with butter is used. However, take into account that mixing gasoline with oil is needed only for two.stroke engines. Four.stroke engines operate on pure gasoline, since their design has a separate container. oil crankcase. There are no 2-stroke gas crankcases in the design of the 2-stroke gasolimers, so you need to pour exclusively gasoline with butter in the tank.

As gasoline, it is recommended to use AI-92 brand fuel. In order not to make a mistake in choosing, you need to read the instructions offered by the manufacturer. Often, most manufacturers recommend using the AI-92 brand fuel, and only some recommend filling AI-95.

Gasoline must be diluted with a small one in a proportion of 1 to 25. This means that 40 ml of two.stroke oil must be added per 1 liter of gasoline. However, not everything is so unambiguous here. The proportion 1 to 25 is universal, but each tool model has its own values. These values ​​are also indicated by the manufacturer in the instructions. details about how to properly dilute gasoline with butter into a lawn mower is described here. After breeding gasoline with butter, pour a full tank, and start work.

It is interesting! If a four.stroke lawn mower is refuel, then pure gasoline must be poured into the tank, and engine oil is added to the oil container to the maximum level.

Engine maintenance

Air.cooled engines are installed in the lawnmands, so the clean ribs of the cooling system (fan) provide quality of work and protect from overheating. To clean them, sometimes you have to remove some external parts of the engine. It is good to clean the compressed air, but you can also a simple soft brush.

The engine needs to be seasoned only with high.quality fuel, it affects its performance, service life, and, consequently, on your budget saving. It is necessary to drain gasoline before winter, though it is better to produce all the old gasoline, then the raid is not formed. After gasoline leaves, turn the starter, then all the valves will close. The dressing is done in the spring.

Periodically should be replaced by oil and candles. The oil is changed according to the term specified in the instructions. Drain the old and dispose of, and fill a new, but only the right class and viscosity. In some engines, the drain is located below, and it happens that you need to turn the equipment to one side. It is better to drain the oil with a non.cooled engine, then it flows faster and captures with it a lot of accumulated garbage. Leyite oil to the level and do not allow dirt from getting.

You need to change candles, if they have worn out, covered with rust, burned out. If you have a raid or soot on the candle, then clean it, or you can immediately put a new one, while putting the desired gap (according to the instructions) and carefully tighten it using a dynamometric key.

Also do not forget to clean, and if necessary, change fuel and air filters. The more dust in places of operation, the more often it is necessary to do this, and before winter it is necessary. instructions for launch

In order to easily start a lawn mower, it is necessary to familiarize yourself with 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.


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.


Electric trimmer for grass. a good country option. In this category, two types of trimmers can be distinguished: network, battery. In terms of power, they are inferior to gasoline, but suitable for mowing a small household territory, cleaning paths, flower beds.

Network models are more productive and powerful. With their help, you can mow grass for several hours. At the same time, make sure that the device does not overheat, take breaks. The only drawback of a trimmer for grass is attachment to electricity.

Battery trimmers for grass

Battery models are light, comfortable. Suitable for women, older people, adolescents. Power and charge are enough for work in the personal territory. The main disadvantage is the battery life: it is enough for 30-90 minutes of mowing. Charging takes several hours.

Electric trimmers for the grass do not pollute the environment, do not emit much noise, easy to maintain, do a great job of performing the tasks, are an excellent addition to the main lawnapers, can work in places.

How to disassemble a carburetor and which valve to clean

Having removed the carburetor lid (unscrewing several bolts) you will see the first valve. the fuel feed needle. And in the center of the carburetor (formed by a kind of circle) there will be the opposite end of the lever, connected to the needle of fuel supply. You can check the fuel supply by clicking on the lever. the needle should move freely. If it hurts or is difficult, it is best to clean and grease the part with special means and a cylinder with compressed air.

The inlet valve is also located there. It can only be checked with a small tube, trying to blow the air in both directions. it should pass the air only in one direction, from its concave side. If the air does not pass, then it is necessary to clean the valve. There are two ways to do this, but we will only consider safe. To do this, take a screwdriver and carefully unscrew the small screw next to the valve needle. do it on a flat surface, otherwise, if you lose the screw or needle, you will have to replace the carburetor completely.

By unscrewing the screw, carefully remove the needle and spring, and then with a blunt end of a match or wire, remove the membrane. All parts of the valve must be washed with gasoline, dried and assembled the valve again, and then the carburetor itself. When assembly, it is necessary to inspect once again and if necessary replace all damaged membranes, gaskets.

After assembly, it is necessary to check the launch of the trimmer for the grass. if it does not happen, then you need to check all the systems again. It is for this reason that it is not recommended to independently clean the carburetor for people without experience.

The air damper drive is faulty

A sign of this malfunction is a “heavy” launch of a trimmer for grass after downtime, especially in cold weather. You can eliminate the breakdown by removing the air damper case and disassemble it, check the fastening of the lever and the damper. If there is a backlash, then the part is definitely replacing. These details are easy to find in a store of spare parts for gasoline trimmers, and replacing them will not be difficult.

This is the most difficult problem in the solution, which can only be caused by the use of incorrect fuel, so it is best to contact specialists. But if you decide to engage in the replacement of the rings yourself, be prepared for complex diagnosis. you will have to sort through the entire motorcycle to exclude all other breakdowns, only after that proceed to the bulkhead of the engine.

The main signs of rings of rings are a heavy start “on cold”, a trimmer for grass does not hold idle speed in an unheated state, and also has increased fuel consumption. The speeds are stabilized after the engine heated, and the trimmer for the grass can work relatively normal. but dumping in the speed set there is.

Before disassembly, check what type of engine is used in your motorcycle. The engine can be two.stroke. its disassembly is simple and subject to anyone, and maybe four. such an engine must first be disconnected from the chain drive of the gas distributor, and then completely disassembled. We will not describe the disassembly of the engine. there are many models in the market, as well as ways to disassemble them, we will immediately move on to the rings. Remove the pistons from the engine and carefully inspect them for damage.

If the rings are not torn, but lay down, they can be restored with a gas burner, they warm them well. If the rings are torn, they need to be replaced, also with the help of the burner to heat the old ones and wearing new ones according to the instructions. After that, the engine can be assembled by previously cooing the pistons.

The result of proper a gasoline trimmer for grass

After you have been running the lawn mower by the instructions, as a result, we get a tool ready to work. Of course, it is best not only to read the stages, but also to see the crowding on the video from specialists. The result of the correct actions will be obtained:

  • operation of the benzo tool for a long time;
  • high.quality start of the device and stability of the submitted power;
  • lack of unforeseen repairs of a trimmer for grass after high.quality pounding;
  • Lack of overheating.

In this regard, the primary processing of the Chinese braid for grass is an integral part of the quality work of the device that can work flawlessly using benzos knives or cutting fishing lines of different diameters when processing territories available in the special store “Spit for grass”.

Mow security

What are the precautions when working with a trimmer? There are several simple and understandable points, after which you can avoid dangerous situations and minimize the likelihood of injuries:

  • Do not use a trimmer for grass in raw and wet weather (especially an electric trimmer for grass);
  • Dress in front of a boosting body so as not to damage the skin with pieces of grass stems flying from a disk or fishing line at high speed;
  • Keep a distance of 15 meters from other people and pay attention to the signs that others can give;
  • With the help of headphones or beryushi;
  • Use an electric trimmer for grass to make sure that the wire from the extension cord is always behind;
  • Put on tightly rubber boots that are easily washed after work;
  • With the help of gloves and protective glasses, to avoid small stones in the eyes and respiratory tract;
  • In case of injury, consult a doctor immediately.

In addition, do not forget to look back, suddenly you will encounter an obstacle in front or side. When diving a bar with a blade into thick thickets of grass, keep in mind that there can be stone, stump or berries (for example, strawberries). Working with a trimmer requires discipline and attention, but as soon as you understand simple rules, this will become familiar, understandable and will bring only positive emotions from the results.

Preparation of the fuel mixture

To provide the tool with productive operation, it is important to learn how to prepare the fuel mixture. If your trimmer for grass is equipped with a 4-stroke engine, then with the preparation of combustible liquid you can not bother, since such units work on gasoline, and the oil is poured into a separate container. The fuel-oil mixture is used for flooding in trimmers for grass with 2-stroke engines. To prepare it, you need only 2 components:

Mix the liquids in the ratio specified in the operation manual. It also contains information about what fuel and oil are recommended to use.

Important! In no case should you use a spent car oil. For gasoline trimmers, there are special lubricants of a special consistency and composition.

Prepare such an amount of fuel mixture so that you manage to develop in one cycle, because when stored the oil is precipitated, fuel loses its properties and becomes unsuitable for further use.

The first launch of the tool

The first launch of a gasoline trimmer for grass is carried out only after you assessed the condition of the gearbox and flooded the gas-lubricant material inside the tool. The work is carried out according to this scheme:

  • place the tool on the floor in a horizontal position;
  • Close the air damper, moving the control of the lever to the desired position;
  • Skip fuel into the carburetor;
  • Turn on the ignition toggle switch;
  • Pull the launch cable until you feel resistance;
  • pull the cord 3-4 times until the tool starts;
  • Open the air damper.

It may be that the lawn mower will not start the first time. This is within normal. Slightly open the air damper of the gas ciner, try to start the tool again.

The first launch of a trimmer for grass

When everything is checked and the prepared fuel mixture is flooded into the tank, there comes the moment of the first launch of the trimmer for the grass before its rolling.

To do this, you need to perform the following manipulations:

  • Place a motorcycle on a flat horizontal surface;
  • We move the air damper control lever to the position closed;
  • We pump up the fuel in a carburetor with several pitching of the primer;
  • Turn on the ignition toggle switch;
  • Smoothly pull the launch cord until you feel resistance;
  • After that with a cord 3 4 sharp jerks, until the lawn mower should be launched;
  • After starting, open the air damper.

If the lawn mower does not start or staller the first time, slightly open the air duct damage on the carburetor and try to run again.

We proceed to running the lawn mower

After starting, do not rush to immediately run the trimmer for the grass. Let the engine idle for 5 minutes. While heating is going on, adjust the air supply to the air damper with a lever so that the rogue with a fishing line or with a knife does not rotate.

As soon as the tool warmed up, we completely open the air supply to the corresponding lever to the “ON” position and squeeze the gas trigger for 1/2 and hold the seconds of seconds 30.

Then we drop the gas, let the trimmer work on xx 30.40 seconds. In this mode we continue 10 minutes 15. Then we mock and let it rest for 15 20 minutes.

Having cooled the lawn mower, we continue to run the engine according to the previous scheme.

Start a hot, a trimmer for grass should already be with an open air damper. Try not to hold the gas for a long time, since the movable details of the tool only rubbing each other. And do not let the engine work at idle for a long time as it can overheat.

Playing the gearbox of gasoline braid for grass

The next stage is the a gas reducer gearbox for grass. To do this, select a plot with soft young grass. Kosim 5 10 minutes with 1/2 2/3 from full gas.

After we take a break for 20 25 minutes. Repeat the cycle 3 4 times.

In general, therapist for the lawn mowing according to the described algorithm is carried out until the fuel mixture in the tank is fully generated. After which the tool is ready for long.term work. In the process, follow the temperature regime of the gearbox and the motor. They should not overheat.
