Motorcycle trimmers, or trimmers, are popular. These low-cost machines can be used in summer cottages, personal agricultural plots, farms and public utilities. However, the practicality of such devices can be appreciated only by those who can properly start their operation.
Peculiarities
It should be noted that the petrol braid 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 gasoline trimmer is also not difficult. Moreover, 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 a cutting device is included in the delivery.
How to get started?
How the gasoline scythe 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 new equipment, but also when preparing the spit 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 out.
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, you will have to lubricate the boom gearbox once every 8-10 hours.
But running in a petrol cutter 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 trimmer with the minimum possible amount of oil. All the same, the grease does not completely burn out, and its excess forms coke, which clogs the piston and cylinder.
After the end of the tests and filling the fuel mixture, the following manipulations should be done:
- put the 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 motor starts running, open the choke.
How to achieve running-in parts?
The launch technique just described is quite suitable even for Chinese technology. But sometimes the first start fails or the 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 properly, you still should not run in the device right away.
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 warming 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 trimmer cools down, the engine is run in according to the already described scheme, but with the initially open damper.
It is necessary to abandon the long gas delay, as poorly running-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 stepping to a power of 50-75%.
After such a session, the brushcutter is stopped for 20 or 25 minutes . Usually 3-4 cycles are enough for the trimmer gear 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.
