How to start the trimmer for grass in the cold

How to mow grass correctly with a garden trimmer

Working with a brushcutter is easy enough if you know the basic principles and have a hand. Here are a few tips to help you get a good result and keep your lawn well groomed:

  • If you have tall grass or strong stemmed weeds to cut, use two circular motions. First cut the top of the stems from right to left with the mower, then mow the rest in the opposite direction.
  • If you need to mow a large area, divide the area into squares, starting on the outer sides and gradually moving toward the center.
  • Work on slopes is carried out according to the following algorithm: start at the bottom, mowing the grass in parallel lines and gradually climbing up. The grass will fall down onto the cut area without interfering with your work.
  • To mow around an obstacle, take the protection of the chain saw into account. Move around an obstacle by gently moving the tool around it.
  • Always install only good quality attachments on your petrol grass trimmer. Working with low quality of line or blades may not cut the grass, but uproot it. the lawn will soon deteriorate.

How to mow with a fishing line

It is safer to mow with a trimmer with a cord or fishing line than to work with knives. But the working efficiency will be lower. It’s always better to match and combine different mowing heads for different jobs.

When working with a gasoline trimmer, which has a fishing line, you need to adhere to the following tips:

  • Mow about 10 cm above the ground;
  • mow the top part of the grass first, and then cut the stem at the base. this will help to avoid winding on the working part;
  • It is better to drive the unit in the same direction in which the spool rotates;
  • When mowing lawns, it is better to work with the tips of the line to reduce the load on the engine;
  • every 15 minutes you need to let the power tool have a rest.

How to mow grass with knives

The blades (disk) are good for hard grass or shrubs, but you must follow some safety rules. Here are the basic points to keep in mind when using blades:

  • The blades are suitable for cutting hard grass, young trees or bushes.
  • The more difficult the task, the larger the diameter of the blade disc should be.
  • Install only discs on your grass trimmer that are the right size for the tool’s capabilities. Otherwise, the grass trimmer may break.
  • When the tool is on, it should only be used for mowing, not for replacing consumables, lubrication, or inspection of the chain saw.
  • Choose discs based on the information on it and follow the manufacturer’s instructions.
  • Do not sharpen the blades yourself, it can ruin the part.

Step by step instruction on how to mow grass with a disc mower and save fuel

Start the lawnmower mainly on the ground. Some craftsmen know how to start the tool by holding it in their hands, but it is quite difficult and dangerous. After starting the tool, you can start using it. You should first put on protective gear and an off-loading belt. Depending on the tool, the straps are available with carabiners or cable ties. If a carabiner or latch is used, then after starting the engine, the tool should be secured and start working. If cable ties are used, the belt has to be put on with the tool in operation.

Initially the belt should be balanced. That means, that in spite of the total weight of the tool, there should be as little load on the mower’s hands as possible. With hands the mower only moves the tool, and if you don’t do the balancing, you will quickly get tired while working. The whole weight should be on the shoulders of the person.

When the tool is ready to use, the instructions for mowing grass with a chain saw are as follows:

  • Move left and right slowly, keeping the grass trimmer at the same distance from the ground
  • The mower should move unhurriedly (half a step at a time). Specialists call the mower’s movements in duck steps
  • The biggest challenge that beginners face is maintaining a stable RPM. Change the working RPM while mowing depending on the degree of foliage. If the grass is young, you don’t need to work at full throttle to cut it
  • The mower should be able to feel the tool working. If the grasshopper doesn’t cut the material you have to increase the engine speed. It is not advised to use the mower at full speed all the time
  • Specialists have worked out the following optimal mode of grass mowing with petrol-trimmers. in one side you have to increase revolutions above average (almost full throttle), and when you move it back, the gas is decreased, while making a step forward. This method is relevant in cases where it is necessary to accurately lay the grass in swaths

Often there are disputes among mowers with gasoline mowers about how to mow with a trimmer, whether it is necessary to reset the gas or it is better to work in constant mode. Let’s get into these questions in detail.

  • There is an opinion that it is better to mow with a chain saw in one rpm. This opinion is wrong. Working with the same power not only increases fuel consumption but also affects wear and tear. Dropping the throttle during reverse travel with the tool is useful, because during this period the engine is cooled, as well as the lubrication of the cylinder head. throttle opening causes closing of the throttle valve and, as a result, fuel flows through the idle speed channel and parts are lubricated
  • Gas release allows not only to mow grass, but also to accurately place it in swaths. Moving the tool in one direction allows for mowing, while moving it in the opposite direction creates a swath
  • The disc is moving only in one direction and it is useless to hold the tool at a constant RPM when it is moving in the opposite direction
  • When the throttle is released the cutting wheel starts to rotate the crankshaft by inertia, and a coasting motion is always beneficial

If you mow in one RPM mode (usually done by beginners), it will lead to higher fuel consumption and engine overheating. For comparison, you can see how a chainsaw works. The sawmill gives maximum rpm only when necessary, but when the tree sawing is completed, the chainsaw runs at idle, thereby cooling it down.

Inspecting the gearbox of the lawnmower and lubricating it

Check the gearbox before starting the petrol grass trimmer. Lack of lubricant or too little of it causes friction in the gearing, which has to work at quite high revolutions. As a result, the gears will overheat. Gearbox on brushcutter fails. To prevent the occurrence of such a failure in the process of use and helps to constant inspection.

If you notice, before starting the STIHL electric lawnmower, that the gearbox does not contain enough lubricant or that there is no lubricant, you can fill the housing with LITOL. To do this, you must unscrew the screw on the bend of the gear housing and grease 1-2 ml of LITOL.

After working with a gasoline trimmer for a long time, every 8 to 10 hours add oil to the gearbox.

Very handy. 1 syringe of oil for 1 liter of gasoline. STIHL recommends using an oil that is compatible with your machine. it is ideal, because it has been developed and tested on STIHL power tools.

  • Increase engine power (cylinder diameter, piston stroke). Absolutely impossible task;
  • Increase the fuel supply while simultaneously increasing the air supply. This causes increase in engine rpm and heat output;
  • Reduce the output resistance.

How to start your brushcutter correctly

If your lawnmower is equipped with a two-stroke engine, you have to start it with the choke closed when it is cold.

It is very important to open the choke in time. This is done after the first burst in the engine.

Generally, the mower should start for a few seconds and immediately stop, after which the choke lever is moved to the normal operating position.

Of course, it is first necessary to set the “stop engine”, which is located on the handle, in the start position.

Inspecting the gearbox of a lawnmower and lubricating it

Check the gearbox before starting the gasoline grass trimmer. Lack of lubricant or a small amount of it increases the friction of the gear reducer, working at a fairly high RPM. The result is overheating of the gears, too. Gearbox of brushcutter fails. To prevent the occurrence of such a failure during use and helps to continually inspect.

If you notice before starting your petrol grass brushcutter that the correct amount of lubricant is missing or that there is no lubricant in the housing, “LITOL” is used. To do this, you need to unscrew the screw on the curve of the gear housing and fill it with 1-2 ml of LITOL.

Working with a gasoline trimmer for long periods of time, add grease to the boom gearbox every 8 to 10 hours.

A few more tips when working with a brushcutter

Mowing. Hold the grass trimmer head directly over the ground at an angle. The work is done by the end of the stringline. Give the string a chance to work at its own speed. Do not press the brushcutter line against the cutting area! This overloads the motor and the mowing head. they can fail or melt!

Cutting. Grass trimmer is ideal for cutting grass that is hard to reach with a regular lawnmower. Hold the stringline parallel to the ground when cutting. Avoid pressing the grass trimmer head to the ground, as you can ruin the lawn and damage the tool.

Trimming with a knife. Mow with a pendulum motion from side to side, the movement from right to left will be working, and from left to right will be returning. The blade should cut the grass with its left edge (on a clock face. between 8 and 12).

Preparing the right fuel mixture

Before you start the new lawnmower engine you also have to mix the fuel right. As is known for two-stroke motors, it is prepared from special two-stroke oil and gasoline, taken in certain ratios. You can find out the proportions from the manual supplied with the tool or on the lubricant label. From the manual you will also learn the recommended type of fuel, as well as the recommended type of engine oil.

Only use small amounts of fuel that are enough for one cut of grass. Use special canisters made of plastic or separate glass or metal containers for fuel. The best way to get the oil is to use a medical syringe.

Getting ready to run in a new lawn mower many people have a problem with the fuel mix. And the reason for this is that there is a discrepancy between the tool manufacturer’s instructions and the engine oil manufacturer’s instructions. The first ones recommend the ratio 1:25. The latter recommends 1:50. Who to trust?? What to do?

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

What to do in this situation during the running-in of a new tool?? The ideal is to buy exactly the oil that the mower manufacturer recommends. In the case of running-in engines, when there is no possibility to buy the recommended oil, it is better to buy a good Husqvarna two-stroke oil for the gasoline-powered tools of the same name. It is not cheap, but it lasts long. It is necessary to mix it as it is written in the instruction on the jar.

Remember, it is best to use the proportions given by the oil manufacturer. But it’s better to find out by experiment whether the proportion written on the scythe is suitable or not. If at the proportion recommended by the manufacturer of the grass trimmer, the engine is snotting oil and you can see leaks on it, then the proportion should be increased.

The first start of the electric grass trimmer

Adjusting and running in the trimmer for grass electric is also not difficult. To do this, it should be assembled and run, but do not work immediately. It will be best to run the device several times (3-5 will be enough) to make sure that it starts easily. If the machine starts up without any problems, you can run it in for five minutes on the lawn, without heavy loads.

Almost all modern electric grass trimmers are designed for 20/20 operation, t.ะต. Twenty minutes operation and twenty minutes rest. The last one is necessary to let the engine cool down a little. If you operate such a grass trimmer for more than 20 minutes, without giving it the necessary time to rest, the engine resource can decrease dramatically, as it experiences an increased load.

Mode of continuous operation in the electric trimmer is not provided, but, nevertheless, if not run-in correctly, gradually increasing the load and operating time (up to 20 minutes, but no more), the device may not work properly, bringing the owner trouble with constant breakdowns and failures in operation.

It’s important to remember that running the machine in and out is an essential part of proper care. This makes the machine last a lot longer. Its further operation depends on the first start of the trimmer. Do not hurry, even if the amount of work to be done is not small, it is best to give the electric motor a proper rest, because then it will last much longer.

How to start the weed trimmer by pouring 20 g. fuel in the spark plug hole

To start the trimmer for grass (if the grass trimmer does not start), you should first check whether there is fuel in the tank and whether its level is sufficient (whether the fuel reaches the intake hose whether the fuel filter is immersed in fuel). It does not take long to open the cap of the tank and look inside.

Remove the cap and unscrew the spark plug using a spark plug wrench.

Next, you need to check and, if necessary, clean the spark plug electrodes from carbon deposits or other deposits, using a metal brush or a thin screwdriver. Electrodes must be clean. When cleaning the electrodes, be careful not to damage the white ceramic insulator of the central electrode.

It is desirable to heat the spark plug electrodes on a gas stove burner or with a lighter (observing fire safety rules). You can check the serviceability of the spark plug by putting it in the cap and ensuring that the housing is in contact with the engine mass, then turning the grass trimmer engine with the starter and evaluating the presence and quality of the spark between the electrodes of the spark plug.

Pour about 20 g of fuel into the spark plug hole. with a tablespoon, a beaker or a medical syringe. Then immediately reassemble the spark plug and tighten it.

Close the choke (turn on the starter gas) and press the button for manual fuel priming 3 times with a pause for 4 seconds. between each press.

Pull the starter handle several times and start the grass trimmer engine (lawnmower). Close the choke as soon as the grass trimmer engine starts.

If the engine does not start even after that, then it is necessary to replace the spark plug with a new one, as the cause is most likely in it (buy a spark plug with the marking indicated in the Grass trimmer / Lawnmower User Manual).

If the engine still fails to start, clean the carburetor with a carburetor cleaner.

For fast cleaning of a carburetor of a grass trimmer by a carburetor cleaner, it is necessary to remove plastic covers and an air filter to get access to the carburetor (it is desirable to remove a carburetor completely from the engine and to disassemble). Spray a few times with a carburetor cleaner in the center jets and other accessible (through) carburetor passages. This can be repeated several times and make sure the channels are clean and free of debris.

It is necessary to check the spark arrester in the muffler of gasoline grass trimmer / lawnmower for contamination. If it is clogged with sludge, this may be the main reason for poor engine starting and the mesh should be cleaned with a metal brush. The spark arresting screen in the grass trimmer’s muffler is designed to prevent glowing particles from flying out of the muffler, which can cause a fire by falling, for example, on hay or other easily combustible materials.

How to start the trimmer for grass, if after all done the engine still does not start should be analyzed, if pouring 20 g. If the lawn trimmer is designed to put fuel in the cylinder, the engine will start, work and then choke again, it means that the problem is with the carburetor that either does not put fuel in the cylinder at all or does not put enough fuel in, or mixes fuel in the wrong proportions. In this case, you must either buy a new carburetor (it can be clogged), or take to the repair carburetor trimmer for grass, or make adjustments to the carburetor yourself. If, however, after pouring 20 g. fuel in the cylinder of the grass trimmer / lawnmower engine does not show signs of life at all, then the cause is the spark plug, which must be replaced with a new one (buy grass trimmer spark plug) or clean the old one.

At the end of the season you should always drain the fuel from the tank as in the trimmer (gasoline mower) and in any other technique with two-stroke motors. Pour fuel from the tank into a bottle through a funnel, then start the trimmer for grass, to work out the remains of fuel from the carburetor until the engine is stalled. If this is not done, then during storage for more than 1 month, the fuel will begin to stratify into light and heavy fractions and oil mixed with fuel will precipitate, which will lead to corking of channels in the carburetor and, accordingly, to the failure of the trimmer for grass.
