How to run in a new brushcutter
It should be noted that the gasoline grass mower is very simple to operate. It is enough to see how other users use this machine to start using it fully. The basic technical functions are intuitive and easy to perform in practice. Properly running in the gasoline grass trimmer is also not difficult. There’s really very little difference between a domestic and a professional lawn trimmer.
The key difference is the type of motor. On machines for professionals, it is more powerful and produces more speeds. The two-stroke engine is more often used in domestic models. The four-stroke models are more robust and have more power, so they are suitable for special applications, difficult terrain, overgrown areas.
In addition, it must be taken into account whether a cutting attachment is included in the scope of delivery.
So let’s start with getting ready for work. How to get your lawn mower in a state of full readiness for use?
Reassemble it first if it is disassembled. Securely fasten the detachable rod in the latches. Carefully check the fastening of the cutting attachment, especially if it is a knife or saw blade. Gasoline grass trimmers, as a rule, are extremely powerful, and the rotation speed of the cutting equipment in them is fantastic. Therefore, poorly fixed blade, firstly, can injure the worker, and, secondly, causes additional vibration in the tool, which can lead to its failure.
Gasoline models are most often equipped with a two-stroke engine, so they need to prepare a fuel mixture. 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 combustible mixture.
It only needs a certain amount of fuel per filling. Do not dilute several liters immediately with a “reserve”, because the composition must always be fresh.
Inspecting the lawnmower gearbox and lubricating it
Checking the gearbox before starting the petrol grass trimmer should be done on a regular basis. Lack of or little lubricant increases friction in the gear reducer’s gearing, which operates at a fairly high rpm. The result is overheating of the gears as well. Gearbox of brushcutter fails. This can be prevented by regular inspection during operation.
If you find, before starting the gasoline grass mower, an insufficient amount of lubricant in the gearbox or its absence, “LITOL” is put in the housing. To do this, it is necessary on the bend of the gear housing to unscrew the screw and spritz “LITOL” in an amount of 1-2 ml.
Working with a gasoline trimmer for a long time, every 8-10 hours add grease to the boom gearbox.
How to run in parts?
The described startup method is quite suitable even for Chinese technology. But sometimes it’s impossible to start from the first time or the grass trimmer stops immediately. In this case, similar manipulation is carried out when closing the air duct valve. If then nothing works, you need to contact a professional. If the system is working correctly, never start the machine immediately.

Start the engine by idling for 5 minutes. Important: if the instructions state a different time, you must follow the instructions. During the warm-up it is necessary to adjust the air supply. By setting different positions of the air dam lever, they ensure that the cutting part does not move. After waiting for warm-up, open the choke fully and set the power to 50% of maximum.
Hold the lever in this position for 20. 30 seconds. With the throttle turned all the way down, let the harness run for 30 to 40 seconds. Then set the power to 20% and wait 10-15 minutes. The engine is then switched off and left to stand at rest for ¼ hour. When the grass trimmer has cooled down, the engine starts as already described, but first the choke is opened.
Holding the gas for long periods of time should be avoided, as poorly machined parts can be damaged. Prolonged idling is also contraindicated. This will lead to overheating. This completes the engine, after which you need to start the transmission. This procedure is performed in an open area where soft, fresh grass is growing. It is mowed for 5. 10 minutes without interruption, periodically treating with 50-75% power gas.
After such a session, mowing stops for 20 or 25 minutes. Usually 3-4 cycles are enough for proper operation of the grass trimmer for many years. often than not, they try to start the device before the first filling is complete.
See the features of the hedge trimmer in the following video.
Proper first startup and startup of the hedge trimmer are very important steps when starting a new tool. On the one hand, they allow you to save the motor life of the gasoline engine, laid down by the manufacturer, because at this stage there is a crushing of moving units and parts. On the other hand, the first necessary skills for working with a trimmer are acquired when we talk about the first tool in my life.
- Preparing for the first start of the brush cutter
- Inspection and lubrication of the gearbox
- Preparing the correct fuel mixture
- First Trigger
- Getting started on gasoline brushes
Do you run the brushcutter in for a while??
The longevity of a brushcutter depends on correct use, following certain rules increases the service life of the gearbox and engine. Modern models have a 2-MIX or 4-MIX engine. They run on 92 octane gasoline and special 2-stroke oils for gardening equipment. Add 20 ml of oil per liter of fuel. The proportions may vary slightly depending on the manufacturer.
When buying a new brushcutter many people ask whether a running-in period is necessary? There are many different opinions, but experts say that running-in is not necessary. To lapping tool parts, it is enough to follow a few simple rules:
- Allow the brushcutter to work at high engine rpm for the first three spindles, but without too much load. mow for 10-15 minutes at a time, with breaks;
- start a new cycle only after the tool has cooled down completely;
- Never run the engine at idle speed. this creates soot deposits in the combustion chamber.
The engine is subject to wear and tear if it is not operated properly and deposits form on the cylinder walls and in the exhaust port because of incomplete combustion of the air-fuel mixture. Pieces of carbon may chip off and damage parts in the cylinder or piston assembly. This reduces engine life and can lead to engine failure.
After these measures your brushcutter is ready to work at full load. To prolong the life of your power tool you need to remember to maintain it in good time: change the fuel filter in the fuel tank once a year, clean the air filter periodically, check the quality of the lubrication in the gearbox. Every 100 motor-hours you should take the tool to the service center for adjustment of the engine valves. That way the lawnmower lasts the specified period and does not need unscheduled repairs.
How much should run in a new trimmer for grass?
The lawnmower engine should be run with medium or slightly above-average load on the engine in cyclic mode: mowing the grass lasts 1. 1,5 minutes, then 15. 20 seconds of idling. The engine reaches its peak performance after a few full tank fills.
Most brushcutter manufacturers at this level indicate that a TC-W3 oil is the right oil for the engine. This means that 2T mineral, synthetic and semi-synthetic oils can be used. For professional trimmers, it is advisable to buy only oil that the manufacturer recommends.
Starting diesel and petrol engines
Engine failure occurs not only after the purchase of new equipment, but also when installing a new engine, after overhaul, modernization or replacement of individual components of the power tiller (motocultivator).
Before starting the procedure, you need to check the correctness and quality of the equipment assembly, the fastening of all connecting bolts, the presence of the necessary lubricants. Further algorithm of actions is as follows
- Pour the required amount of oil into the crankcase, check its level with a probe.
- Add the required amount of fuel (A92 gasoline or diesel, depending on the type of engine) to the fuel tank.
- Check connection of oil level sensor to the relay.
- Open the valve of the fuel tank.
- Turn on the engine starter several times, ignoring the ignition. On a diesel engine, the decompressor must be on.
- Open the air valve of the gasoline carburetor.
- Start the engine and close the plug when it is warm.
Then you can start the engine. At the first stage, it is recommended to start with low revolutions, gradually and gradually increasing them to values slightly above average. In this case it is necessary to work through all the gears of your power harvester one by one, for 1-2 hours. This will allow you to check not only the engine, but also the gearbox of the unit.
The second stage involves cultivating, plowing and transporting small loads (up to 200 kg). At this stage it is very important not to exceed the permissible load of the single axle tractor specified in the operating instructions. Example: If the maximum tillage depth indicated in the data sheet is 30 cm, then when starting the engine the depth of the tiller must not exceed 15 cm.
Starting a diesel engine is not fundamentally different from starting a gas engine, but it is important to remember that any engine does not like to idle for a long time at high speeds. This is a very common mistake, which leads to serious consequences, up to the engine overhaul. For different power tillers the breakdown process may take up to 10 hours.
After engine and cylinder block failure, the oil in the crankcase and gearbox must be replaced with a new one, based on the recommendations in the instruction manual.
Grass trimmers, they are popular grass trimmers. These budget machines can be used at dachas, private farms, farms and utilities. However, the practicality of such devices can only be appreciated by those who can properly start their work.
The main difference between a lawn mower and an electric grass trimmer
Answering the question than a lawn mower differs from an electric grass trimmer, it is worth noting their power source. Based on the name, we can see that the lawnmower runs on a fuel mixture (gasoline-oil), and the electric grass trimmer from the electric network.
To operate an electric grass trimmer, an extension cord is necessarily needed, which is not always convenient when mowing. That’s why it’s a good idea to size your mowing area and decide if you have a power source before you buy a machine. Gasoline grass trimmers in this comparison are more convenient to maneuver.

Inspection of lawnmower gear and its lubrication
Checking the gearbox before starting a gasoline grass trimmer should be done on a regular basis. Lack of lubricant or a small amount of it increases the friction of the gear train, which works at quite high revolutions. As a result, overheating occurs and the gears. The gearbox of a brushcutter fails. To prevent the occurrence of such a breakdown in the process of operation and helps regular inspection.
If you find, before starting the gasoline grass trimmer, a lack of lubricant in the gearbox or its absence in the body put “LITOL”. To do this, you need to unscrew the screw on the bend of the gear housing and pour “LITOL” in an amount of 1-2 ml.
Working with a gasoline trimmer for a long time, every 8-10 hours, add grease to the gear rod.
The result of a proper running-in of the gasoline grass trimmer
After you have carried out running-in of the lawnmower according to the instructions, as a result we will get a ready-to-work tool. Of course, it’s best not only to read the steps, but also to see the running-in on a video from the experts. The result of correct actions will be received:
- trouble-free operation of the gasoline tool for a long time;
- qualitative start of the device and stability of supplied power;
- no unforeseen grass trimmer repairs after a quality run-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”.
What safety precautions when working with a trimmer? There are some simple and straightforward points after which you can avoid dangerous situations and minimize the likelihood of injury:
- Do not use the grass trimmer in wet and damp weather (especially the electric grass trimmer);
- Dress your body before mowing so as not to damage your skin with chunks of grass stalks flying from the disc or line at high speed;
- Keep a distance of 15 meters from other people and pay attention to the signs that 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 tightly fitting rubber boots that are easily washed after work;
- Use gloves and safety glasses, avoid getting small stones in your eyes and respiratory tract;
- In the event of injury, consult a doctor immediately.
Also, remember to look back, suddenly you will encounter an obstacle in front or on the side. When plunging the blade bar into dense thickets of grass, be aware that there may be a rock, stump, or berries (such as strawberries). Working with a trimmer requires discipline and attention, but once you understand the simple rules, it will become habitual, understandable and bring only positive results.

Put your belt on
You couldn’t work a grass trimmer without a belt: it also redistributes stress from your hands to your shoulders and back and helps optimize recoil. You should wear a belt to the already assembled unit when the rod is in the engine ditch.
The belt itself is mounted on a metal hinge, which ensures a snug fit even under maximum load. The belt attachment design is the same on all models and requires no additional manipulation during assembly. Inserting the loop into the hole provided is sufficient. And it will be secured.
It is not enough to put the belt on, you need to adjust it on yourself. Belt adjustment depends on the height of the person. You can check if the belt is tensioned correctly. If your shoulders and arms don’t tire quickly enough when mowing and the vibration doesn’t cause muscle discomfort, the belt is set correctly. If your arms tire quickly, turn off the unit, loosen the belt, and tighten it again. This procedure should be done until the grass trimmer is lying flat “at hand” and when it is weighted, the length of the rod is optimal in relation to the surface.
Adjust the length of the belt using the loop is quite simple: simply tighten it to decrease the volume, or loosen it to increase the length.
