Before starting the chain saw, allow it to run at low speed for a few minutes, ensuring that the saw chain is lubricated with oil. During work, the accelerator can be set to high speed. After finishing a tank of oil, it is recommended to rest for about 10 minutes. After work, clean the chain saw’s heat sink for proper heat dissipation.

The air filter of the chain saw should be dedusted every 25 hours. If needed, you can clean it yourself. The foam filter element can be cleaned using washing liquid or gasoline, followed by rinsing with clean water. Squeeze it dry, soak it in engine oil, and then install it after removing excess oil.

When using a new chainsaw, ensure that the saw chain is properly tightened so that it can rotate when pushed. Hold the chainsaw with the guide teeth parallel to the guide plate. After a few minutes of use, carefully observe and repeat this process several times.

If the gasoline chainsaw exhibits issues such as refueling and flameout, decreased performance, or overheating, it is usually a problem with the filter. Before starting work, check the filter. A clean and qualified filter should appear thorough and bright when observed under sunlight. If the filter is not clean enough, it should be washed with hot soapy water and dried to ensure normal chainsaw operation.

When the saw teeth become un-sharp, use a special file to sharpen the cutting teeth of the saw chain. File in the direction of the cutting teeth, not in the opposite direction. Maintain an angle of around 30° between the file and the chain saw chain for optimal results.

Yes, it is recommended to add chain saw oil before using the chainsaw. This provides lubrication to the chain saw, reduces frictional heat between the saw chain and guide plate, and protects both the guide plate and the chain saw chain from premature failure.

After using the chain saw, it is important to maintain it for optimal efficiency in the next use. Clear impurities from the oil inlet hole at the base of the guide plate and the guide plate groove to ensure smooth oil flow. Additionally, remove debris from the guide plate head and add a few drops of engine oil.

The size of the chainsaw you need depends on the diameter of the trees you intend to cut. Smaller trees can be effectively cut using battery or electric chainsaws with bar lengths of 10-14 inches. For heavy-duty cutting, a chainsaw with a bar length of 14 inches or greater is recommended.

The guide bar length of the chainsaw is the most important factor to consider. Longer guide bars are more effective for cutting trees with larger diameters. Additionally, the engine displacement and horsepower should be considered for heavy-duty cutting tasks.

For cutting large-diameter trees, a professional-grade chainsaw with a guide bar length of 20 inches or more is recommended. These chainsaws are powerful and designed for heavy-duty tasks.

For light cutting tasks like trimming, pruning, and cleaning up small trees or branches, electric or battery-operated chainsaws with guide bar lengths of 10-14 inches are suitable. These chainsaws are convenient for occasional use by homeowners.

No, beginners should start with smaller chainsaws and gradually move to more professional, gas-powered models. Chainsaws with guide bars of 18 inches or less, preferably 10-12 inches, are recommended for beginners. Electric or battery-operated chainsaws are also suitable for inexperienced users.
