MAINTENANCE

Spark Arrester

Failure to heed the following warnings while servicing the spark arrester could 

result in serious injury or death. Never run the engine in an enclosed area. 

Remove any combustible materials from the area. Wear eye protection and 

leather work gloves. Do not stand behind or in front of the vehicle while purging. 

Never go under the vehicle while it's inclined.
The exhaust system can get extremely hot. Do not perform service on the spark 

arrester while the system is hot. Allow components to cool sufficiently before 

proceeding.

Occasionally, the spark arrester may accumulate carbon, which can 

restrict the exhaust if left unattended. Purge the spark arrester.
1. Position the vehicle on a level surface.
2. Place the transmission in PARK.

3. Remove the arrester 

clean-out plug from the 

bottom of the muffler.

4. Start the engine.
5. Quickly squeeze and 

release the throttle lever 

several times to purge 

carbon from the system.

MAINTENANCE

PVT System

Do not modify any component of the PVT system. Doing so may reduce its 

strength so that a failure may occur at a high speed. The PVT system has been 

precision balanced. Any modification will cause the system to be out of balance, 

creating vibration and additional loads on components.
The PVT system rotates at high speeds, creating large amounts of force on 

clutch components. Extensive engineering and testing has been conducted to 

ensure the safety of this product. However, as the owner, you have the following 

responsibilities to make sure this system remains safe:
• Always follow all recommended maintenance procedures. Always look for 

and remove debris inside and around the clutch and vent system when 

replacing the belt.

• Perform service as outlined in the owner's manual. Your POLARIS dealer can 

assist.

• This PVT system is intended for use on POLARIS products only. Do not 

install it in any other product.

• Always make sure the PVT housing is securely in place during operation.
