Change Air Filter
A correctly serviced air filter protects internal engine parts
from airborne dirt and dust. Poor filter maintenance will allow
dirt and dust to be drawn into the engine, causing wear to
the intake system and contamination of the oil. Dirt in the
oil forms an abrasive mixture which wears down moving
parts.
WARNING
Fuel and its vapors are extremely flammable and explosive
which could cause burns, fire or explosion resulting in
death or serious injury.
• Never start or run the engine with the air cleaner
assembly or the air filter removed.
NOTICE Do not use pressurized air or solvents to clean
the filter. Pressurized air can damage the filter and
solvents will dissolve the filter.
