Lubrication Recommendations

Suspension

To maintain rider comfort and to retard wear of the pivot shafts, lubri-

cate the suspension pivot shafts with Polaris Premium All Season 

Grease several times during the season and again before summer storage 

each year. Lack of lubrication will result in reduced performance and a 

less comfortable riding experience.

NOTE:

The stars in the following illustration indicate lubrication points. A 

grease gun kit complete with grease and adaptors is available to lubri-

cate all fittings on Polaris snowmobiles. See page 82 for the part num-

bers of Polaris products.

IMPORTANT: Make it a weekly practice to check for loose bolts and 

nuts on the suspension system. If any loose bolts are found on the rail be 

sure to clean the threads and apply LOCTITE 262 before tightening.

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 Premium 

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 appearance 

but it can also extend the life of various components.

The best and safest way to clean your Polaris vehicle is with a garden 

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.

NOTE:

If a high pressure car wash is used (not recommended), grease all 

zerk fittings 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 system.

• 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 decal becomes illegible or comes off, contact your Polaris 

dealer to purchase a replacement. Replacement safety decals 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.

CAUTION

High water pressure may damage components. Polaris recommends 

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

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 Premium 4 Synthetic 0W40 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.

NOTE:

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 carbure-

tor, run the engine until it stops.
