HOW TO SERVICE
THE AIR FILTER
NOTE: Never run the engine with the air filters (air cleaner
cartridge, pre-cleaner) removed. The air filters will help protect
the engine against wear. For the correct replacement filter, see
the parts list for the engine.
CAUTION:
Do not use pressurized
air or solvents to clean
cartridge. Pressurized air can damage cartridge; solvents will
dissolve cartridge.
If a filter is stamped WASHABLE, it can be washed with warm water
and mild soap.
IMPORTANT: Rinse in tap water with SCREENside up allowing
dirt and debris to filter out. Leave filter to dry overnight before
reinstalling.
