To clean the air filter
Clean the air filter regularly from dirt and dust. This
prevents carburetor malfunctions, starting problems,
loss of engine power, wear to engine parts and more
fuel consumption than usual.
1. Remove the cylinder cover and the air filter.
2. Use a brush or shake the air filter clean. Use
detergent and water to clean it fully.
Note:
An air filter that is used for a long time can
not be fully cleaned. Replace the air filter regularly
and always replace a defective air filter.
3. Attach the air filter and make sure that the air filter
seals tightly against the filter holder.
Note:
Because of different work conditions, weather
or season, your product can be used with different types
of air filter. Speak to your servicing dealer for more
information.
