How to Use a String Trimmer. 10 Skills to Master

User’s manual

A mixture of gasoline and lubricant is used as fuel. It is necessary to prepare the mixture based on certain ratios. 1 part of the adapted engine oil and 25 parts of gasoline with an octane rating of at least 92 are taken. If there is insufficient lubrication, the device may fail.

properly, petrol, grass, trimmer

Also, to prepare the fuel mixture for the first two fillings, add 10% more oil than recommended.

Important! the grass trimmer does not need to be run in, but it is advisable to use only half the power at initial start-up.

Do not stockpile a large amount of fuel mixture, as old fuel does not lubricate the engine.

To prolong the life of the motor, adhere to the following rules:

  • Do not use low quality gasoline. Don’t forget to add oil!
  • The lawn mower must not be turned on at high revs without load.
  • Do not use lubricant for 4-stroke engines.

After 10 hours of operation of the petrol trimmer, you must:

  • Check the condition of the muffler;
  • Clean or replace the air filter;
  • Check the gap between the spark plug contacts. It should be 0.6-0.7 mm;
  • Clean ventilation holes;
  • Add oil to the gearbox.

It is not recommended to carry out self-repair of the power unit. If any breakdowns occur, you need to take the brushcutter to a service center.

After every 45 minutes of operation, a technical break is made for 10-15 minutes, while completely switching off the mower. This is necessary to prevent overheating of the device.

Disadvantages of the Hopper 043 grass trimmer:

  • Noisy;
  • Pollutes the environment with exhaust emissions;
  • Requires careful maintenance;
  • Heavy considering the weight of the engine and full fuel tank.

Let’s start running in the lawn mower

After starting, take your time to roll in the grass trimmer immediately. Allow 5 minutes to warm up the engine at idle speed. While warming up, adjust the air flow with the choke lever so that the spool with line or knife does not rotate. As soon as the tool has warmed up, open the air supply completely by moving the corresponding lever to the “ON” position and squeeze the gas trigger 1/2 and hold for 20 30 seconds. Then we release the gas, let the trimmer run for 30.40 seconds. In this mode, we continue for 10 15 minutes. Then we muffle and let it rest for 15 20 minutes.

Having cooled down the lawn mower, we continue to run in the engine according to the previous scheme. Start hot, the grass trimmer must be already with the air damper open. Try not to hold the gas for a long time, as the moving parts of the tool only rub against each other. And do not let the engine idle for a long time as it can overheat.

The next stage is running in the reducer of the gasoline grass scythe. To do this, you must select an area with soft young grass. We mow for 5 10 minutes with podgazovki 1/2 2/3 of full throttle. After that we take a break for 20 25 minutes. The cycle is repeated 3 4 times.

In general, the running-in of the lawn mower according to the described algorithm is carried out until the fuel mixture in the tank is completely depleted. Then the tool is ready for continuous work. During operation, monitor the temperature conditions of the gearbox and motor. They shouldn’t overheat.

First start-up and running-in of the lawn mower

Correct first start-up and running-in of a lawnmower are very important steps when starting a new tool. On the one hand, they allow you to preserve the service life of a gasoline engine, laid down by the manufacturer, since at this stage, moving parts and parts are lapped. On the other hand, the first necessary skills of working with a trimmer are acquired when it comes to the first tool in life.

Lawnmower Gearbox Inspection and Lubrication

The gearbox must be checked regularly before starting the petrol grass trimmer. Lack of lubrication or a small amount of it increases the friction of the gear train of the gearbox, which operates at rather high speeds. The result is overheating and gears. The brushcutter’s gearbox is out of order. To prevent the occurrence of such a breakdown during operation and helps regular inspection.

If it is detected, before starting the gasoline scythe for grass, there is an insufficient amount of lubricant in the gearbox or its absence, “LITOL” is put into the body. For this it is necessary to unscrew the screw on the bend of the gear housing and to inject “LITOL” in the amount of 1-2 ml.

Working with the petrol trimmer for a long time, add grease to the boom gearbox every 8-10 hours.

Starting the grass trimmer for the first time

When everything has been checked and the prepared fuel mixture is poured into the tank, it is time to start the grass trimmer for the first time before running it in. To do this, you need to perform the following manipulations:

  • Place the brushcutter on a flat horizontal surface;
  • Move the choke control lever to the closed position;
  • We pump fuel into the carburetor with several strokes of the primer;
  • Turn on the ignition switch;
  • Smoothly pull out the starting cord until you feel resistance;
  • Then make 3 4 sharp jerks with the cord until the lawn mower starts;
  • After starting, open the air damper.

If the mower does not start or stalls the first time, slightly open the air damper on the carburetor and try to start again.

Advantages of the Hoper 043 petrol grass trimmer model:

  • Ability to work up to 45 minutes without interruption;
  • Mobile;
  • It is easy to use a trimmer to treat areas near a fence, tree, etc.;
  • The two-stroke engine is fuel efficient and does not weigh down the structure.

The main types of petrol trimmers

Gasoline brushcutters are divided into household, professional and semi-professional. The second type is less popular, due to the ability to process only the space close to the power source.

Interesting! The general structure of household and professional brushcutters is almost identical. they consist of a head with a cutting tool, a fixing bar and a motor. The main differences lie in the choice of a more functional type of handle. Professionals prefer the high-speed brushcutters Prorab and AL-KO, the popular Huter lawn mower and others.

How to break in a brushcutter? If you need to perform complex work, you can choose a semi-professional model that has the necessary functions to perform complex tasks and the necessary compactness for convenience in home use.

Preparing to start the mower for the first time

Before you start the mower for the first time, you need to perform a number of sequential steps:

  • Inspect the gearbox and lubricate it;
  • Prepare the correct fuel mixture.

We recommend doing them not only when buying a new grass trimmer, but also when preparing an old tool for a new season after storage.

Features of running in a lawn mower

Motorcycle trimmers, aka grass trimmers, are popular. These low-cost machines can be used in summer cottages, in personal agricultural holdings, farms and public utilities. However, the practicality of such devices can be appreciated only by those who can properly start their operation.

The main characteristics of a benzokos

The main differences that determine the choice of the consumer are the type of engine: the basic principle of differentiating devices is carried out according to the type of engine. Power and RPM may be a subject of preference. The shape of the rod and handle and the functionality of the cutting tool are of no small importance. The main method of differentiation can be the consumed fuel, according to which brushcutters are divided into gasoline and electric.

During operation, monitor the temperature conditions of the gearbox and motor. They shouldn’t overheat.

What nozzles for gasoline brushcutters are offered by manufacturers

The range of grass trimmer attachments is simply amazing. This can be a drill and a lopper, an aerator for cleaning small ponds, a cultivator that looses beds, an air blower and snow blower for removing leaves and snow from paths, and even a boat motor. The purchase of a cultivator for brushcutters allows you to process flower beds and beds in a short time, forgetting about the days of work spent loosening them.

The benefits and value of petrol trimmers

The main advantage of this compact tool is the ease of mastering the control process. Having seen how a more experienced gardener uses a brushcutter, you can easily learn how to work and perform basic functions without much energy consumption. Running in a petrol brushcutter takes a little time and makes life much easier for a person constantly fighting lush vegetation. Another advantage is the ability to process a relief area and problem areas that previously had to be processed manually. for example, slopes or ditches, the edges of decorative landscape design structures, or small areas between trees and bushes.

Important! The characteristic of the engine (two- or four-stroke) allows not only to save time, increasing the speed of processing problem land tenure. Working with a device whose main fuel is gasoline, you can achieve significant power, and not get confused in electrical wires, as is the case with power tools.

Fuel mixture preparation

To ensure productive operation of the tool, it is important to learn how to prepare the fuel mixture. If your grass trimmer is equipped with a 4-stroke engine, then you don’t have to bother with preparing flammable liquid, since such units run on gasoline, and the oil is poured into a separate container. The fuel / oil mixture is used for pouring into grass trimmers with 2-stroke motors. To prepare it, you need only 2 components:

  • petrol;
  • two-stroke oil.

Mix fluids in the ratio indicated in the instruction manual. It also contains information about which fuel and oil is recommended to use.

Prepare such an amount of the fuel mixture so that you have time to work out in one cycle, because during storage the oil precipitates, the fuel loses its properties and becomes unsuitable for further use.

Grass Trimmer Run-In Algorithm

After starting the engine, do not rush to immediately start intensive work. Let the tool warm up for a couple of minutes. idle. During this time, adjust the position of the choke lever. Now you can remove the gas trigger, hold it for 20-30 seconds. Then release the gas, let the tool run for another 15 minutes at idle speed.

Allow the petrol grass trimmer to cool down after the first start. It is possible to wind the tool with a warm engine with the air damper already open. Now the gearbox should be run in. We perform the actions in the following sequence:

  • select an area on the territory where low, soft grass grows;
  • mow for 5-10 minutes, adding gas regularly;
  • stop the tool and let it cool down;
  • repeat the cycle 3-4 times.

During the running-in process, you must completely develop the fuel-oil mixture, which is poured into the tool. After competently performing the above actions with a gasoline trimmer, you can already fully mow the grass.

Gearbox inspection and lubrication

So, you’ve bought a new gasoline grass trimmer and are planning to mow the grass. Where to begin? The first step is to check the condition of the gearbox. By the way, this must be done before each start of the tool. Lack of lubricant or lack of it increases the friction of the gear train, which runs at high speeds. As a result, the gears overheat, wear out faster, and the gearbox may fail. Regular inspection of the mechanism will help prevent breakdowns.

The oil for the reducer (it is recommended to use “LITOL”) is carried out into the housing. There is a special bend here for this. The grease is poured using a syringe. You don’t need much. just 1-2 ml is enough. Oil must be added to the gearbox every 8-10 hours of operation of the gasoline grass trimmer.

Starting the tool for the first time

The first start-up of the petrol grass trimmer is carried out only after you have assessed the condition of the gearbox and have filled in petrol and lubricant inside the tool. The work is carried out according to the following scheme:

  • place the instrument on the floor in a horizontal position;
  • close the air damper by moving the control lever to the desired position;
  • pump fuel into the carburetor;
  • turn on the ignition switch;
  • pull the starter rope until you feel resistance;
  • pull the cord 3-4 times until the tool starts;
  • open the air damper.

It may be that the mower will not start the first time. This is within the normal range. Open the mower choke slightly, try to start the tool again.

Running in the grass trimmer: how to properly prepare the tool for work?

The performance and service life of a grass trimmer is highly dependent on whether the tool has been run in correctly. It is important to competently prepare the equipment for work: check all components and mechanisms, pour lubricant into the gearbox, carefully inspect the device. This will provide the petrol trimmer with flawless performance for a long period, prevent breakdowns, and save the engine resource. At the running-in stage, you need to work carefully and accurately, because the new components are only rubbing against each other. On the other hand, the novice operator also acquires the skills necessary to operate the tool.

Common mistakes when running in a grass trimmer

Even experienced users often make mistakes when trying to break in a gasoline grass trimmer, let alone a beginner. If you know the essence and specifics of mistakes, it will be easier for you to avoid them. Let’s consider the most common.

  • Lack of lubrication in the gearbox. Yes, people rarely check the state of this mechanism. It is a fact. But you need to do it. The gearbox must always be sufficiently lubricated, otherwise overheating and engine breakdown. Again, excess oil must also not be allowed, as it contaminates channels and valves, which then have to be cleaned.
  • Running in at idle speed. Today’s petrol trimmers are technologically sophisticated devices that require competent service and maintenance. It is impossible to run in the tool at idle speed, since the fuel does not completely burn out.
  • Sharp pressing of the gas button. Can cause the needle to jam in the carburetor. Press the gas key slowly, confidently and smoothly.
  • Intensive work immediately after running in. After completing the running-in, take a hex wrench in your hands and tighten the bolts, self-tapping screws, various screws.
  • Fuel storage in a petrol tank. The time during which the diluted fuel mixture is suitable for use does not exceed 1 week. Gasoline loses its properties. The additives contained in the oil decompose, therefore the mixture cannot provide full lubrication of the elements of the piston group. It is recommended to drain off the remaining fuel immediately after the end of the work, if it was not possible to use it up, start the brushcutter, work until the tool comes to a complete stop.
  • The use of fuel with additives. For a lawn mower, it is best to take ordinary AI-95 or AI-92 gasoline. Fuel with additives such as Mustang, Energy contains additives that soften the oil seals, as a result of which the rubber elements lose their properties, begin to let air through.

Run in the tool correctly. Use quality fuel and oil, always follow the manufacturer’s recommendations for operating, maintaining and repairing the gasoline grass trimmer. And then your equipment will serve for a long time, regularly performing the assigned tasks.

How to get started?

How the gasoline scythe for grass will show itself during further operation largely depends on the literacy of the first start-up. Errors can reduce the life of the device. The fact is that after starting, the moving mechanisms of the working apparatus will rub against each other. Additionally, the skills of using the trimmer are formed. This is very important in cases where this technique is used for the first time.

Begin by inspecting the gearbox and the quality of its coating with grease. Then the fuel mixture is prepared according to the instructions.

Important: such a run-in will be useful not only when mastering a new technique, but also when preparing a grass scythe for work after winter storage. If there is no or very little lubrication on the gearbox, the gear train will be subject to very high friction. Because of this, the gears begin to warm up and wear off.

Noticing a lack of lubrication or its absence, you need to add a portion of “Litola”. The procedure is very simple: unscrew the screw located on the bend of the gear housing. Through the freed channel, add 1-2 ml of lubricant with a technical syringe. During daily work with the trimmer, once in 8-10 hours, you will have to lubricate the boom gear.

But running in a lawn mower is not limited to just filling in oil.

Two-stroke engines require a combustible mixture of two-stroke oil and gasoline. It is prepared in the proportion indicated in the instruction manual for the instrument or on the lubricant label. Fuel preparation should be done little by little, so that only one mow is enough. You need to place the fuel supply in the following container:

  • plastic canisters;
  • glassware;
  • metal containers.

It is recommended to take oil with a medical syringe. This will allow you to more accurately observe the dosage. Sometimes another question arises. the manufacturer of the tool and the manufacturer of engine oils indicate different proportions of the combustible mixture, so it is difficult to decide which instructions to follow.

The solution is simple: you need to run in the gasoline grass trimmer with the least possible amount of oil. All the same, the grease does not completely burn out, and its excess forms coke, clogging the piston and cylinder.

After the end of the tests and filling the fuel mixture, the following manipulations should be done:

  • put the grass trimmer on a flat surface;
  • move the lever to the “closed” position;
  • pump fuel into the carburetor;
  • start the ignition system;
  • pull the launching cord with smooth movements, expecting resistance;
  • immediately after that, make 3 or 4 strong jerks;
  • as soon as the engine starts, open the choke.

Features of the

It should be noted that the petrol grass scythe is very easy to operate. It is enough to see how other users use this unit to start using it fully. Performing basic technical functions is intuitive and does not require any difficulties in practice. Correctly running in a petrol grass trimmer is also easy. over, there is almost no difference between the devices of the household and professional categories.

The key difference is the type of motor. On professional equipment, it is more powerful and gives out more revs. The two-stroke engine is more commonly used in household models. Four-stroke units are more reliable and produce more force, therefore they are suitable for special conditions, difficult and overgrown areas.

In addition, it must be taken into account whether there is a cutting device included in the delivery.

Features of running in a lawn mower

Motorcycle trimmers, aka grass trimmers, are popular. These low-cost machines can be used in summer cottages, in personal agricultural holdings, farms and public utilities. However, the practicality of such devices can be appreciated only by those who can properly start their operation.

How to achieve running-in parts?

The startup technique just described is quite suitable even for Chinese technology. But sometimes the first start fails or the grass trimmer stalls immediately. In this case, the same manipulations are carried out with the slightly open air duct damper. If even then nothing works, you need to contact a specialist. If the system is working normally, you shouldn’t run the device right away anyway.

First, the engine should warm up at idle speed for 5 minutes. Important: if the instructions indicate a different time, then it is necessary to follow its instructions. During the warm-up period, it is necessary to adjust the air supply. By setting different positions of the choke lever, they ensure that the cutting part does not move. After waiting for warm-up, open the damper completely and set the power to 50% of the maximum.

In this position, the lever is held for 20 to 30 seconds. Dropping gas to a minimum, allow the streamer to run for 30-40 seconds. Then they set the power to 20%, and wait 10-15 minutes. After that, the engine is turned off and left alone for ΒΌ hour. When the grass trimmer cools down, the motor is run in according to the already described scheme, but with the initially open damper.

It is necessary to abandon a long gas delay, as poorly run-in parts can be damaged. Long idle operation is also contraindicated. it will lead to overheating. This completes the running-in of the motor, then it is necessary to run in the gearbox. This procedure is carried out in an open area where soft, fresh grass grows. It is mowed for 5 to 10 minutes without interruption, periodically gas up to 50-75% power.

After such a session, the brushcutter is stopped for 20 or 25 minutes. Usually 3-4 cycles are enough for the grass trimmer gearbox to work properly for many years. Most often, they try to run in the device until the first fuel filling ends.

But you also need to monitor the temperature of the gear and motor assemblies. After running in, the oil must be changed.

For the features of running in a lawn mower, see the following video.

Lawnmower Gearbox Inspection and Lubrication

The gearbox must be checked regularly before starting the petrol grass trimmer. Lack of lubrication or a small amount of it increases the friction of the gear train of the gearbox, which operates at rather high speeds. The result is overheating and gears. The brushcutter’s gearbox is out of order. To prevent the occurrence of such a breakdown during operation and helps regular inspection.

If it is detected, before starting the gasoline scythe for grass, there is an insufficient amount of lubricant in the gearbox or its absence, “LITOL” is put into the body. For this it is necessary to unscrew the screw on the bend of the gear housing and to inject “LITOL” in the amount of 1-2 ml.

Working with the petrol trimmer for a long time, add grease to the boom gearbox every 8-10 hours.

Preparing to start the mower for the first time

Before you start the mower for the first time, you need to perform a number of sequential steps:

  • Inspect the gearbox and lubricate it;
  • Prepare the correct fuel mixture.

We recommend doing them not only when buying a new grass trimmer, but also when preparing an old tool for a new season after storage.

Preparing the correct fuel mixture

Before starting the running-in of the new engine of the lawn mower, it is also necessary to prepare the fuel mixture correctly. As is known for two-stroke engines, it is prepared from a special two-stroke oil and gasoline, taken in certain ratios. You can find out the proportions from the instructions that came with the tool or on the lubricant label. From the instructions, you will also learn the recommended type of fuel, as well as the recommended type of engine oil.

Prepare fuel in small quantities, sufficient for one mowing of grass. Use special plastic canisters for fuel, or separate glass or metal dishes. Oil is best drawn up with a medical syringe.

When going to run in a new lawnmower, many people face a problem in preparing the fuel mixture. And the reason for this is the discrepancy in the instructions of the tool manufacturer and in the instructions of the engine oil manufacturer. The former recommend a 1:25 ratio. The latter recommend 1:50. Whom to believe? How to proceed?

According to experts, if manufacturers write a ratio of 1:25 or 1:30 in the instructions for the brushcutter, then most likely this is either a cheap tool with poor cooling, or the manufacturer does not know what kind of oil the consumer will add. But here you need to understand that an excess of lubricant does not in the best way affect the performance of the grass trimmer. Excess oil does not completely burn out when the engine is running. It cokes, clogs the cylinder and piston.

How to deal with this situation when running in a new tool? The ideal option would be to purchase exactly the oil recommended by the lawn mower manufacturer. In the case of run-in engines, when it is not possible to purchase the recommended oil, it is best to purchase a good Husqvarna two-stroke oil for the gasoline-powered tool of the same name. It is not cheap, but it lasts for a long time. It is necessary to stir it as it is written in the instructions on the bank.

Remember, it is best to use the proportion provided by the oil manufacturer. But whether the proportion that is written on the braid is suitable is better to find out by experiment. If, with the proportions recommended by the grass trimmer manufacturer, the engine is snotty with oil and smudges are visible on it, then the proportion must be increased.

First start-up and running-in of the lawn mower

Correct first start-up and running-in of a lawnmower are very important steps when starting a new tool. On the one hand, they allow you to preserve the service life of a gasoline engine, laid down by the manufacturer, since at this stage, moving parts and parts are lapped. On the other hand, the first necessary skills of working with a trimmer are acquired when it comes to the first tool in life.

Starting the grass trimmer for the first time

When everything has been checked and the prepared fuel mixture is poured into the tank, it is time to start the grass trimmer for the first time before running it in. To do this, you need to perform the following manipulations:

  • Place the brushcutter on a flat horizontal surface;
  • Move the choke control lever to the closed position;
  • We pump fuel into the carburetor with several strokes of the primer;
  • Turn on the ignition switch;
  • Smoothly pull out the starting cord until you feel resistance;
  • Then make 3 4 sharp jerks with the cord until the lawn mower starts;
  • After starting, open the air damper.

If the mower does not start or stalls the first time, slightly open the air damper on the carburetor and try to start again.

Let’s start running in the lawn mower

After starting, take your time to roll in the grass trimmer immediately. Allow 5 minutes to warm up the engine at idle speed. While warming up, adjust the air flow with the choke lever so that the spool with line or knife does not rotate. As soon as the tool has warmed up, open the air supply completely by moving the corresponding lever to the “ON” position and squeeze the gas trigger 1/2 and hold for 20 30 seconds. Then we release the gas, let the trimmer run for 30.40 seconds. In this mode, we continue for 10 15 minutes. Then we muffle and let it rest for 15 20 minutes.

Having cooled down the lawn mower, we continue to run in the engine according to the previous scheme. Start hot, the grass trimmer must be already with the air damper open. Try not to hold the gas for a long time, as the moving parts of the tool only rub against each other. And do not let the engine idle for a long time as it can overheat.

The next stage is running in the reducer of the gasoline grass scythe. To do this, you must select an area with soft young grass. We mow for 5 10 minutes with podgazovki 1/2 2/3 of full throttle. After that we take a break for 20 25 minutes. The cycle is repeated 3 4 times.

In general, the running-in of the lawn mower according to the described algorithm is carried out until the fuel mixture in the tank is completely depleted. Then the tool is ready for continuous work. During operation, monitor the temperature conditions of the gearbox and motor. They shouldn’t overheat.
