MAINTENANCE
Filter Systems
Air Filter
Always change the air filter at the intervals outlined in the Periodic Maintenance Chart
beginning on page 52. Service the air filter more frequently if the vehicle is operated in wet
conditions or at high throttle openings for extended periods.
1. Lift the cargo box to access the air box.
2. Remove the air box cover and inspect the
gasket. It should adhere tightly to the cover
and seal all the way around.
3. Remove the air filter.
4. Do not attempt to clean the main element.
Install a new air filter.
Tip: Apply a small amount of general purpose grease
to the sealing edges of the filter before installing.
5. Inspect the air box for oil or water deposits.
If present, drain them into a suitable
container.
Fuel Filter
Your POLARIS vehicle is equipped with an in-line fuel filter. Have your dealer replace it
after every 100 hours of operation. Do not attempt to clean the fuel filter.
Breather Filter and Hoses
1. Lift the cargo box and locate the air box.
2. Follow the right-hand breather line out the
side of the air box and locate the filter.
3. Remove and inspect the filter for debris. Blow
gently through the filter in the direction of the
arrow to check for clogging. Replace as
needed.
4. Check hoses for cracks, deterioration,
abrasion, or leaks. Replace as needed.
5. Reinstall the filter with the arrow pointing
toward the engine. Secure the clamps.
NOTICE: Operation of the vehicle without a breather filter can cause engine damage. Always reinstall
the breather filter after removing it for service.
