What is the technical maintenance of chain saw
1. The newly-made machine is the running-in period from the start of use until the third oil filling. Do not let the engine run at high speed without load during use, so as not to bring additional burden to the engine during the running-in period. During the running-in phase, all moving parts must be adjusted to each other, and there will be a large frictional resistance between the driving parts. Generally, the high-twist saw engine reaches its maximum power after 5 to 15 oil injections. 2. After a long period of full-load operation during the work, let the engine idle for a short time to allow the cooling air flow to take away most of the heat, so that the drive device components (ignition device, carburetor) will not cause adverse consequences due to heat accumulation. 3. Maintenance of air filter. Adjust the damper to the choke position to prevent dirt from entering the intake pipe. Place the foam filter in a clean, non-flammable cleaning solution (such as hot soapy water) to wash and dry. Replace the felt filter. When it is not too dirty, you can tap or blow it gently, but you cannot clean the felt filter. Note that the damaged filter element must be replaced. When installing, pay attention to insert the felt filter with the marked side into the filter housing. 4. Inspection of spark plugs. If there is insufficient engine power, difficulty in starting or idling failure, first check the spark plug. Clean the contaminated spark plug, check the electrode distance, the correct distance is 0.5 mm, adjust if necessary. In order to avoid the risk of sparks and fire, if the spark plug has a separate joint, be sure to screw the nut onto the thread and tighten it, and press the spark plug plug firmly on the spark plug.
