Cleaning The Spark Arrester - Yamaha Grizzly 300 Owner's Manual

11. Insert the air filter element into the air filter
case and install the bolts, and then install the
air filter case cover by hooking the holders onto
the air filter case. NOTICE: Make sure that
the air filter element is properly seated in
the air filter case. Never operate the engine
with the air filter element removed. This
will allow unfiltered air to enter the engine,
causing rapid engine wear and possible
engine damage. Additionally, operation
without the air filter element will affect car-
buretor jetting with subsequent poor per-
formance and possible engine overheating.
12. Install the seat.

The air filter element should be cleaned every 20
40 hours. It should be cleaned and lubricated more
often if the ATV is operated in extremely dusty ar-
eas. Each time the air filter element maintenance
is performed, check the air inlet of the air filter case
for obstructions. Check the air filter case rubber
joint to the carburetor fittings and the rubber joint
manifold fittings for an air-tight seal. Tighten all fit-
tings securely to avoid the possibility of unfiltered
air entering the engine.
