MAINTENANCE OF AIR FILTER

A dirty air lter will restrict air ow to the carburetor, reducing engine performance. If you operate the engine in very dusty areas, change

the air lter more often than specied in the maintenance schedule.

a) Remove the air lter cap. Detach the element;

b) Check the condition of the paper ltering element. Damaged or durty element must be changed.

c) Put the detail on its place.

Caution: Never use gasoline or other dissolvents to clean air lter. Ignition could result. Operating the engine without an air lter, or with

a damaged air lter, will allow dirt to enter the engine, causing rapid engine wear.
