Air Cleaner
All engines have a round air cleaner cartridge. In addition, some engines have a pre-cleaner.
Do not use pressurized air or solvents to clean
cartridge. Pressurized air can damage cartridge;
solvents will dissolve cartridge.
CAUTION
Ensure air cleaner, retainer, and cover are
properly installed before starting engine.
WARNING
Pre-cleaner
To clean pre-cleaner (if equipped), separate it from cartridge and wash in liquid detergent and water. Squeeze dry in a
clean cloth.
