1. Regularly check and clean the exhaust hole on the centrifugal dust removal cover to ensure it is unobstructed, remove any dust from the dust collection tray, and brush the dust on the guide plate with a brush
2. The oil level in the oil pan should be maintained at the oil level mark on the oil pan. The oil level is too low, which affects the filtration effect; Excessive oil level increases intake resistance and sucks oil into the cylinder, causing carbon buildup and even causing "speeding"
3. Regularly clean the oil pan and replace the engine oil. The viscosity of the engine oil must be appropriate. If the viscosity is too high, it can easily block the filter screen, affect the passage of air, and increase the intake resistance; If the viscosity is too low, it reduces the filtration effect and easily sucks oil into the cylinder. Using precipitated waste engine oil is more economical and practical
4. Regularly clean the filter screen. If the filter disc is severely dirty, the upper filter screen should be cleaned at the same time. After cleaning, let it dry and soak it in engine oil. Drip all excess engine oil before reinstalling. If there is a lot of dust accumulation on the inner wall of the suction pipe, it should also be cleaned in conjunction with maintenance
5. The maintenance of foam plastic air filter is mainly to remove the dust accumulated in the shell and clean the plastic filter. To clean the filter, use laundry detergent or soapy water solution. Place the filter in the cleaning solution and gently rub it with your hand to remove any dirt. Then rinse it with clean water. After drying, soak the filter in engine oil and use your hand to remove excess engine oil.
