Mating moving parts are lapped in a limited speed range (from idle to ½ maximum). It takes 3-4 hours with 15 min. breaks every 20-30 min. (for cooling and refuelling).
Do not start cutting (even after a long period of storage) without running-in. Because the excessively rapid change in temperature to which the motor grasshopper is exposed prevents proper polishing of the piston ring faces and cylinder walls; microcracks in the housing castings appear. In addition, the noise of a loaded drive can override the grinding of dry gears and the howling of seized bearings.

Running in the petrol grass trimmer
The most common starting procedure for brushcutters (gasoline grass trimmer). Running in is designed as running the engine at low rpm with no load. To run in, you need to start the brushcutter and let it idle for a while. The first mowing is best done with a fishing line, as mowing lawn grass puts less strain on the engine than mowing hay or bushes. The working load is to be increased gradually, step by step by increasing the engine speed. If you start at high engine speeds, the engine may not run in properly and this will have a negative effect on the rest of the brushcutter’s working life. It is not a good idea to run out all the time when the engine is first running. It is best to mow the lawn for 10-15 minutes after working at idle speed, then stop the machine and let it cool down a little. Use your brushcutter carefully and without sudden movements to avoid hard objects (stones). Hitting a rock can have a negative effect on the operation of nodes that have not yet broken in. In some cases play, noise and hum occurs. This can easily be avoided by correct running-in of the weed trimmer.
Some experts recommend using a trimmer line when mowing under hay, but this is not always correct. Usually the grass in this area is taller, and also the grass base is denser and more mature. Using a fishing line will increase engine wear, because it will have to work at higher engine speeds. Of course, this will also affect performance. Secondly, a line for a trimmer simply is not designed for such loads. By using this material you run the risk of not only the line itself, but also the entire mower. The optimum choice is a disc designed for bushes. it is designed for higher loads. Besides, tall grass is coarser at the base and is cut more productively with a blade than with a line designed for soft, silky lawns.

If to put a rope instead of a fishing line without possibility of its release, it is better to fix reliably two ends of a rope and to cut them off by welding (a drop of the melted metal will keep a rope from dissolving). Grass this tool cuts through at a moment’s notice. It cuts down brush to about a finger’s thickness. It is not as afraid of stones as a disk. There is, however, a problem: wire slices break off during wear and these twisted wires remain on the mowing site. If you step on it, you could hurt yourself.
But that’s half the trouble. the bits of wire left in the field. A line for a trimmer, breaking off, weakens dynamic impacts on the transmission and engine, a cable does not give such an opportunity. The result is wear and tear on the brushcutter.
You should also remember that a piece of rope, untwisted by centrifugal force during the rotation of the trimmer head, flies like a bullet. Imagine hitting someone in the leg or in the eye?
Using a cord, wire or multi-strand cable instead of a fishing line causes the grass trimmer to break down very quickly. It is also a direct violation of safety precautions!
Experienced users recommend to buy a line for trimmer with a “star” profile. It cuts much better than a round saw. a 3 mm trimmer line easily cuts thumb-thick stems and consumes less power.
