How to turn on the grass trimmer for grass

Running in the engine of a brushcutter. The peculiarities of the lawnmower running-in

It should be noted that the gasoline grass trimmer is very easy to operate. It’s enough to see how other users use this machine to start using it to its full potential. Performing the basic technical functions is intuitive and does not require any difficulties in practice. Properly run-in gasoline trimmer for grass will also not be difficult. Not only that, there is almost no difference between the devices of the household and professional categories.

The key difference is the type of motor. On the technique for professionals, it is more powerful and produces more speed. The two-stroke motor is more often used in domestic models. Four-stroke machines are more robust and give more power, so they are suitable for special conditions, difficult and overgrown areas.

In addition, you should take into account whether there is a cutting attachment included.

Pre-starting preparations

So let’s start with getting ready for work. How do you get your mower ready for use??

First of all, reassemble it if it is disassembled. Secure the detachable boom in the latches. Carefully check that the cutting attachment is locked in place, especially if it’s a blade or saw blade. Gasoline grass trimmers are usually extremely powerful, and the rotational speed of the cutting attachment in them is fantastic. Therefore, a poorly fixed blade, firstly, can injure the worker, and, secondly, causes additional vibration in the tool, which can lead to its breakage.

Gasoline models are most often equipped with a two-stroke engine, so they require fuel mixture preparation. what is its purpose? Since these motors do not have a crankcase and a separate system for oil lubrication, this role is performed directly by the fuel mixture.

It is prepared in certain proportions and for one filling. you should not dilute several liters with “reserve”, because the composition should always be fresh.

Mowing the grass

Purpose of the trimmer head (grass trimmer reel, mowing head, grass trimmer spool)

  • To remove all unwanted vegetation under walls, along fences, curbs, around trees, posts, bushes, between stumps and other obstacles.
  • To cut the grass in places inaccessible to lawn mowers.
  • To selectively cut thinned grass and weeds before mowing a garden plot in hay.
  • To weed the weeds in the bed between the plants.
  • To shred potato foliage in the vegetable garden before digging it up.
  • To remove grass and weeds completely, e.g. from paths.
  • To sweep (creating an air vortex from the grass trimmer’s high line speed).

Note

The trimmer head (mowing head or grass trimmer reel) has a high output when mowing grass, t.к. it is lighter behind the metal blade and has a larger grip diameter of 45 cm, compared to 25 cm for the hay knife.

Variety of tools

Three versions of garden trimmers are available for sale. electric, battery and gasoline. Plug-and-play models are less common, as they have minimal autonomy due to their connection to the power grid. In addition, in terms of economy, this is not the best grass trimmer for mowing. An electric tool can justify itself only in the work around the house, if there is an opportunity to summon extensions for connecting cables.

Potential for churning flying rocks puts windows at risk in homes and cars. Shields around the trimmer head are in place to reduce flying debris and protect the operator. no one removes the shields after the modified grass trimmer is no longer under warranty or can be used safely.

When refueling, make sure the engine is stopped and the grass trimmer is placed on a flat, level surface. preferably not grass. The grass trimmer should never be left on the grass for an extended period of time. Refueling should be done with the proper system to avoid leaks or overfilling.

Gasoline models have always been considered a direct competitor to electric models. They offer high power, virtually no restrictions on movement, and can even handle shrub cutting. But, a gasoline grass trimmer for mowing the grass is also characterized by high weight, noisy operation, strong vibrations, exhaust emissions and high cost. The cordless versions are not tied to a power source either, but they lose out to petrol trimmers in terms of power.

Be sure to use the appropriate string weight as specified in the owner’s manual. A grass trimmer string that is too thick for the motor can cause damage. Some grass trimmers can accept a trimming blade, but never use a blade on a trimmer that is not designed to use trimming blades. Accessories that are not designed for a particular grass trimmer can create excessive vibration, engine wear or binding. This can lead to motor strain, possible component failure and potential damage to the operator.

Popular questions about petrol garden trimmers

In this section, we’ve answered a few common questions about gasoline trimmers.

Why the lawnmower does not start?

If you can’t start the gasoline trimmer or it immediately stops, you need to check the ignition by removing the spark plug. A dry spark plug means that the problem lies in the system responsible for the fuel supply. Wet spark plug indicates a problem with the ignition system. If the spark plug has soot on it, it must be cleaned or replaced.

Another reason could be a clogged air filter. If it is dirty with oil, you need to clean, wash and dry it.

Why does the lawnmower stop??

Depending on the exact moment at which the grass trimmer stops, the causes may be different.

When accelerating

  • If the gasoline grass trimmer stalls when you press the gas, you need to check the air damper. If it is set in the closed position, you need to set it in the open.
  • Another option is a clogged filter.
  • The gasket between the cylinder and carburetor can also be damaged.
  • A cracked fuel hose will cause air intake.

At idle speed

It happens that the lawnmower stalls after a while after starting. Causes may be:

  • Improperly adjusted carburetor;
  • a dirty carburetor, filter or choke;
  • air in the carburetor system;
  • malfunction in the ignition system;
  • Lack of gasoline.

Why a lawn mower heats up?

  • One of the warmest parts is the gearbox. If there is not enough lubrication in the mechanism, the gears will experience friction and become hot. This can also happen with new gearboxes where the gears have not yet been lapped. Operating temperatures of up to 60°C on the gearbox.
  • Use at maximum loads is another cause of mower overheating. The tool must be rested regularly.
  • There may not be enough oil in the fuel mixture. this leads to oil starvation, increased friction and generates a lot of heat during operation.
  • Contaminated cooling air flow holes.

Instructions for using the gas grass trimmer to learn how to start the tool

Before you start working with the tool you have to buy it first. How to get the brush, let’s look at in detail. To begin, the tool should be placed on a flat surface so that the disc mounted on the shaft does not catch on anything. After that, we start starting the brush cutter motor:

  • First, the fuel must be introduced into the starting system. To do this, press the primer 4-5 times (soft hemisphere on the carburetor)
  • Next, set the carburetor switch to “OFF”. This switch is responsible for opening and closing the air damper. Turning the switch to “OFF” mode allows the fuel mixture to be enriched when starting
  • There is a knob on the handle next to the gas pedal. It is responsible for turning the ignition switch on and off. Switch the ignition switch to mode “1” before starting.
  • Now you can start. To do this, hold the tool with one hand and pull the starter knob sharply with the other. If the tilt engine doesn’t start the first time, don’t despair. Start attempts should be made before the engine starts. Usually this should be done 2-3 times.
  • If after 5 repetitions the engine does not start, you need to repeat the fuel intake in the first layer, and start again.
  • Once the engine starts, the throttle switch should be set to the “ON” position. It means that the mixture of fuel and air enters the cylinder.
  • Allow the tool to idle for 15-30 seconds until the engine warms up, then you can start mowing the grass.

The above instructions on starting the engine and trimmers are suitable for cold starting. If there is a pause while the tool is running, there is no need to close the throttle when you restart a cold engine. You just need to turn on the ignition and pull the starter grip.

Getting ready for work

If this is your first time mowing the lawn, take a few minutes to learn how to properly mow with a line trimmer. Walk along the lawn and remove any rocks, sticks or large debris.

Turn the trimmer on and hold it so the handle is snug against your thigh. Make sure the head is at a comfortable height for cutting the grass. Approach one edge of the area and start cutting the grass.

As you are trying to make an even cut, keep the head parallel to the ground and make short sweeping motions. It’s best to set a higher cutting height first so you can adjust to your ideal cutting height.

The gasoline trimmer likes cleanliness. Check the air filter and fuel filter for cleanliness. It is better to leave gasoline, bought at gas station, for 2 days and pass it through a simple filter. a piece of baize cloth.

Electrical equipment is checked in the following way:

Unscrew the spark plug, check the gap between the electrodes. Adjust the correct gap between the electrodes, you can “grandfather’s” way. Take a razor blade, break it in half and put a homemade dipstick between the electrodes. If the blades fit tightly, then the gap is perfect.

Put the cap of the high-voltage wire on the spark plug and lean the spark plug against the metal surface of the engine. yank the starter a few times. If the spark strikes well at one point, the gap is adjusted correctly. If not. the spark is weak or “wandering”, it is necessary to re-adjust the electrode gap.

Also in the electrical equipment may be punctured ignition coil. In this case, the lawnmower does not start or starts intermittently and then shuts down or does not start when hot.

Check the serviceability of the coil can be checked in the same way as when checking the spark: unscrew the spark plug, lean it against the body of the grass trimmer. If there is no spark when the starter jerk, or it appears intermittently, you need to change the coil.

The result of a proper running-in of the gasoline grass trimmer

After you have been run-in of the lawnmower according to the instructions, as a result we will get a ready to work tool. Of course, it is best not only to read the steps, but also to see the running-in on a video from the experts. The result of the correct actions will be obtained:

  • no-failure operation of the gasoline-driven tools for a long time;
  • Quality start of the device and the stability of the supplied power;
  • absence of unforeseen grass trimmer repairs after a good running-in;
  • no overheating.

In this regard, the initial processing of the Chinese grass trimmer is an integral part of the quality work of the device, which can work flawlessly, using blades for chain saws or cutting lines of different diameters when processing areas, available for purchase at the special store “Grass Mower”.

Mow safely

What Safety Precautions for Working with a Trimmer? There are some simple and straightforward points after which you can avoid dangerous situations and minimize your chances of injury:

  • Do not use a grass trimmer in wet and humid weather (especially an electric grass trimmer);
  • Wear bodysuits before mowing to avoid damaging your skin with bits of grass stems flying from the disc or fishing line at high speed;
  • Keep a distance of 15 meters from other people and pay attention to signs others may give;
  • Using headphones or earplugs;
  • Use an electric grass trimmer to make sure the wire from the extension cord is always behind you;
  • Wear tight-fitting rubber boots that are easy to clean after work;
  • Using gloves and safety glasses, avoid getting small stones in your eyes and respiratory tract;
  • In case of injury, see a doctor immediately.

Also, do not forget to look behind you if you suddenly encounter an obstacle in front or at the side. When plunging the rod with the blade into dense thickets of grass, be aware that there may be a rock, a stump, or berries (e.g., strawberries). Working with a trimmer requires discipline and attention, but once you understand the simple rules, it will become habitual, understandable and will bring only positive emotions from the results.

First start of the grass trimmer

When everything is checked and the prepared fuel mixture is poured into the tank, it is time to start the grass trimmer for the first time before its running-in. To do this, the following manipulation is necessary:

  • Position the brushcutter on a flat, level surface;
  • Move the choke control lever to the closed position;
  • Pump fuel into carburetor with several pumps of primer;
  • Turn on the ignition toggle switch;
  • Smoothly pull the starter cord until you feel resistance;
  • After you pull the cord 34 jerks until the lawnmower starts;
  • After the start we open the choke.

If the lawnmower won’t start or stalls the first time, open the choke shutter on the carburettor slightly and try to start again.

Start the lawnmower’s running-in period

After starting do not rush to run in the weed trimmer immediately. Allow the engine to idle for 5 minutes. While the machine is warming up adjust the airflow with the choke knob so that the line or blade bobbin does not rotate. Once the tool is warmed up, fully open the air supply by moving the lever to the “ON” position and squeeze the throttle trigger to 1/2 and hold for 20 30 seconds. Then turn off the throttle and let the trimmer work for 30 seconds at idle.40 seconds. Continue in this mode for 1015 minutes. Then turn off the machine and let it rest for 15 to 20 minutes.

Once the lawnmower has cooled down, continue running the engine according to the previous scheme. Starting up the grass trimmer when it is hot should be done with the choke open. Avoid holding the gas for a long time, because the moving parts of the tool are only lapping against each other. And do not let the engine idle for a long time because it can overheat.

The next step is running in the gearbox of the lawn mower. To do this, select an area with soft, young grass. Mow for 510 minutes with startup 1/22/3 of full throttle. After that take a break for 2025 minutes. Repeat this cycle 34 times.

In general the lawnmower runs in accordance with the described algorithm until the fuel mixture in the tank is depleted. After that the tool is ready to work for a long time. Watch the temperature of gearbox and motor during work. It must not overheat.
