Q       What should I do before starting the chain saw and after finishing work?
A       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.
Q       How often should I clean the air filter of the chain saw?
A       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.
Q       What should I pay attention to when using a new chainsaw?
A       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.
Q       What could be the issue if the gasoline chainsaw experiences problems like refueling and flameout, decreased performance, or overheating?
A       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.
Q       How can I maintain the sharpness of the saw teeth on the chainsaw?
A       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.

“This is my NT6210. We are just out of one of the worst storms in living memory here in Ireland. This saw worked for 3 days almost 8 hours a day. My first comment is this saw is very well balanced and constructed. My second comment is it is very economical on fuel. Very happy to recommend this saw to anyone who asks me. Blade is holding its edge very well. Craftop is the Toyota of chainsaws.”
