POLARIS Variable Transmission (PVT) System

PVT Drying

There may be some instances when water is accidently ingested into the 
PVT system. Use the following instructions to dry it out before 
operating.

NOTICE: When washing the vehicle, always avoid spraying water directly 

toward the PVT intake duct. See page 124 for recommended 
washing procedures. 

1. Remove the drain plug from the bottom of the clutch box. Allow the 

water to drain. Reinstall the drain plug securely.

2. Place the transmission in PARK. Apply the brakes. Start the engine.
3. Apply varying throttle for 10-15 seconds to expel the moisture and 

air-dry the belt and clutches. Do not hold the throttle wide open for 
more than 10 seconds.

4. Allow the engine RPM to settle to idle speed. Apply the brakes. 

Shift the transmission to the lowest available range.

5. Test for belt slippage. If the belt slips, repeat the process.
6. Your vehicle requires service as soon as possible. Your POLARIS 

dealer can assist.

carefully remove the air box 
cover. Do not allow the air box 
cover to contact the air filter 
during removal.

NOTICE: Dirt or debris in the air box 

could result in severe engine 
damage. Always clean all dirt 
and debris from the air box

Intake Pre-Filters

The engine and PVT intake pre-filters

box. Inspect both pre-filters before 
each use of the vehicle to ensure 
adequate air flow. If necessary, remove 
the pre-filters and clean with soapy 
water. Dry with low pressure 
compressed air.

NOTICE: When washing the vehicle, 

always avoid spraying water

MAINTENANCE

Spark Arrester

Failure to heed the following warnings while servicing the spark arrester could 
result in serious injury or death.

• Do not perform clean-out immediately after the engine has been run, as the 

exhaust system becomes very hot. Serious burns could result from contact 
with the exhaust components. Allow components to cool sufficiently before 
proceeding.

• Wear eye protection and gloves.

• Never operate without the spark arrester.

• 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.

Periodically clean the spark arrester to remove accumulated carbon.
1. Remove the retaining nut. Remove the arrester from the end of the 

muffler.

2. Use a non-synthetic brush to clean the arrester screen. A synthetic 

brush may melt if components are warm. If necessary, blow debris 
from the screen with compressed air.

3. Inspect the screen for wear and damage. Replace a worn or 

damaged screen.

4. Reinstall the arrester. Torque the nut to 7-9 ft. lbs. (10-12 Nm).
