Air Filter Installation - 2-Cycle Engines
1. Check the condition of the air box and replace if necessary.
2. Replace the filter over the carburetor boot. Make sure the filter is
fully seated in the air box.
3. Tighten the clamp. Do not overtighten, as filter damage could
occur.
4. Check the cover gasket and replace if needed. Be sure the cover is
seated properly, then snap the clips onto the cover.
5. Reinstall the ATV seat.
Air Filter Cleaning - 2-Cycle Engines
NOTE: Always replace the main filter when it becomes dirty. In an
emergency situation, however, you may clean the main filter if you
observe the following practices.
1. Never immerse the main filter in water. Dirt can be transferred to
the clean air side of the filter.
2. If compressed air is used for cleaning, never exceed a pressure of
40 PSI. Always use a dispersion-type nozzle to prevent filter
damage, and blow the air from the inside to the outside.
NOTE: Replace the air filter every 50 hours and more often when the
vehicle is operated in very dirty conditions.
