MAINTENANCE OF THE AIR FILTER

As shown in Fig. 11
Soiled air filters reduce the engine output by restricting air to the carburetor. If the air contains a lot of dust,
the air filter should be checked more frequently.
WARNING! Never run the engine without the air filter element installed.
1. Press tabs at the top of the air filter cover and tilt away from the engine to remove the cover.
2. Remove the filter cartridge.
3. To loosen debris, gently tap the filter cartridge on a hard surface. If the filter cartridge is excessively dirty,
replace with a new one.
Note: Never clean the air filter cartridge with gas or inflammable solvents.
Clean the air filter cartridge only with compressed air or by tapping it.
4. Install the filter cartridge.
5. Close the cover and secure it properly by snapping tabs back into the correct slots at the top.
