Filter Systems

Air Filter

Always change the air filter at the intervals outlined in the Periodic Maintenance Chart.
  1. Lift the cargo box.
  2. Clean all dirt and debris from the air box area.
  3. Unlatch the two (2) cover clips and carefully remove the air box cover. Inspect the seal between the cover and air box to ensure the seal is not torn and has been maintaining a proper seal.
  4. Inspect the air filter and air box for dirt, debris, oil or water. If the filter needs to be replaced, remove the worm gear clamp from the filter neck with a flat-blade screwdriver or 6mm socket. Slide the filter rearward to remove it from the boot, then lift it straight upward and out of the air box.
  5. With the filter removed, clean the intake boot and air box thoroughly and wipe well with a clean, dry cloth.
    NOTICE
    Dirt or debris in the intake boot could result in severe engine damage. Always clean all dirt and debris from the intake boot before installing the filter.
  6. Reinstall the air filter (if clean) or install a new air filter (if soiled). Do not attempt to clean the air filter.
    NOTICE
    Use of a non-POLARIS-approved air filter may cause engine damage. Always use a POLARIS-approved replacement filter. See page 92 for the part numbers of POLARIS products.
  7. Make sure the filter is fully seated on the intake boot and that there is no gap between the filter and boot after installation. Tighten the worm gear clamp to 24 in. lbs. (2.7 Nm).
  8. Reinstall the air box cover. Make sure both hinges are fully inserted. Secure the cover clips.

Spark Arrester

WARNING
  • Never operate the vehicle without the spark arrester.
  • Remove any combustible materials from the area.
Failure to heed the following warnings while servicing the spark arrestor could result in serious injury or death.
  • Never run the engine in an enclosed area. Exhaust contains poisonous carbon monoxide gas that can cause loss of consciousness or death in a very short time.
  • Do NOT perform service on the spark arrester while the system is HOT. Exhaust system temperatures can reach extreme temperatures. Allow components to cool sufficiently before proceeding.
  • Do not stand behind or in front of the vehicle while purging the exhaust system.
  • Never go under the vehicle while it is inclined.
  • Wear eye protection and gloves while servicing.
Use the following procedure to periodically purge accumulated carbon from the exhaust pipe.
  1. Remove the arrester clean-out plug located on the bottom of the muffler.
  2. Place the transmission in PARK.
  3. Start the engine.
  4. Purge accumulated carbon from the system by momentarily revving the engine several times.
  5. If carbon is expelled, cover or plug the exhaust outlet and rap on the pipe around the clean-out plug while revving the engine several more times.
  6. If particles are still suspected to be in the muffler, elevate the rear of the vehicle one foot higher than the front. Block the wheels.
  7. Repeat steps 4 and 5 until no more particles are expelled when the engine is revved.
  8. Stop the engine. Allow the arrester to cool.
  9. Reinstall the arrester plug and remove the outlet cover or plug.
