Lubrication Recommendations

Inspect and lubricate all greaseable components at the intervals outlined 
in the Periodic Maintenance Chart beginning on page 50.

Controls and Linkage
Lubricate all bushings and tie rod ends with a light coat of oil or grease. 
Remove the spindle shafts and lubricate the bushings on the top and bot-
tom of the trailing arm.

Lubricate throttle and brake controls and cables with POLARIS Pre-
mium All Season Grease. Force a small amount of lubricant down the 
cable. See page 58.

Bearings
Always grease drive shaft clutch side bearings with a high quality bear-
ing grease to prevent corrosion, which will destroy the bearings.

Electrical Connections
Separate the electrical connector blocks and clean corrosive build-up 
from the connectors. Lubricate the blocks with dielectric grease and re-
connect. Replace worn or frayed electrical wire and connectors. Be sure 
wiring harnesses are properly secured away from sharp edges, steering 
linkage, moving parts, and hot exhaust components.

Washing the Vehicle

Keeping your POLARIS vehicle clean will not only improve its appear-
ance but it can also extend the life of various components.

NOTICE: High water pressure may damage components. POLARIS recom-

mends washing the vehicle by hand or with a garden hose, using mild 
soap. 

The best and safest way to clean your POLARIS vehicle is with a gar-
den hose and a pail of mild soap and water. 

1. Use a professional-type washing cloth, cleaning the upper body first 

and the lower parts last.

2. Rinse with clean water frequently.

3. Dry surfaces with a chamois to prevent water spots.

Washing Tips
• Avoid the use of harsh cleaners, which can scratch the finish.
• Do not use a power washer to clean the vehicle.

TIP: If a high pressure car wash is used (not recommended), grease all zerk fit-

tings immediately after washing. Remove the spindle shafts and lubricate 
the bushings on the top and bottom of the trailing arm. Also run the vehicle 
to evaporate any water that might have entered the engine or exhaust sys-
tem.

• Do not use medium to heavy duty compounds on the finish.
• Always use clean cloths and pads for cleaning and polishing. Old or 

reused cloths and pads may contain dirt particles that will scratch the 
finish.

• If any label becomes illegible or comes off, contact your POLARIS 

dealer to purchase a replacement. Replacement safety labels are pro-
vided by POLARIS at no charge

Waxing the Vehicle

Your snowmobile can be waxed with any high quality brand of automo-
tive paste wax. Avoid the use of harsh cleaners since they can scratch 
the body finish.

Storage

Off season or extended storage of your snowmobile requires preventive 
measures to aid against deterioration and to prolong the useful life of 
many components.

Fog the Engine
1. Treat the fuel system with POLARIS Carbon Clean. See page 76.

2. Support the front end of the machine so the engine is level or tilted 

slightly rearward.

3. Turn the fuel valve off.

4. Remove the spark plug. 

5. Pour 5cc of engine oil into the cylinder.

6. Slowly pull the recoil starter to turn the engine over two or three 

times.

7. Reinstall the spark plug.

8. Rotate the piston to bottom dead center (BDC) and 

9. Slowly pull the recoil starter handle until resistance is felt. Leave it 

in that position.

10. Clean the engine thoroughly with an oiled cloth.

TIP: If POLARIS fuel system additive is not used, the fuel tank, fuel lines, and 

carburetor should be completely drained of gasoline. Observe all fire safety 
rules when draining the carburetor. Review the fuel-related warnings on 
page 43. To eliminate any fuel remaining in the carburetor, run the engine 
until it stops.

Storage

Stabilize the Fuel
Proper off-season preparation of the engine and fuel system is vital to 
the prevention of rust and corrosion formation on precision engine parts 
during storage. See page 82 for the part numbers of POLARIS products.

1. Fill the fuel tank with fresh fuel.

2. Add POLARIS Carbon Clean Fuel Treatment or POLARIS Fuel 

Stabilizer. Follow the instructions on the container for the recom-
mended amount.

TIP: Carbon Clean removes water from fuel systems, stabilizes fuel and 

removes carbon deposits from pistons, rings, valves and exhaust systems.

3. Start the engine. Allow it to idle for five minutes to disperse addi-

tives through the entire fuel system.

4. Turn the fuel valve off.
