Maintenance of the air filter
As shown in Fig. 16-17
Ensure the air lter is clean and in good condition. A dirty air lter will restrict air ow to the
carburettor, reducing engine performance. If the mower is used in a dusty environment the
air lter should be checked frequently.
WARNING! Never run the engine without the air lter element installed.
1. Unclip and remove the cover.
2. Remove the air lter element.
3. Tap the air lter element several times on a hard surface to remove dirt. If the lter is
excessively dirty, replace with a new one.
Note! Never clean the air lter with petrol or inammable solvents. Clean the air lter
only with compressed air or by tapping it.
4. Install the air lter element.
5. Close the cover and clip it.
