Brake Fluid

WARNING! After opening a bottle of brake fluid, always discard any unused
portion. Never store or use a partial bottle. Brake fluid is hygroscopic, meaning it
rapidly absorbs moisture from the air. The moisture causes the boiling
temperature of the brake fluid to drop, which can lead to early brake fade and
the possibility of accident or severe injury.

The brake fluid level can be seen through a plastic sight glass in the
brake reservoir. If the fluid is sufficient, the sight glass will be black. If
the sight glass is any color other than black, add brake fluid.

Keep the master cylinder cover free of dirt and debris. The vent slits
allow for diaphragm movement, and if they become plugged, movement
of brake fluid below the diaphragm may be restricted, altering brake
function.

We recommend the use of POLARIS DOT 4 high temperature brake
fluid. See page 106 for the part numbers of POLARIS products.

NOTICE: Brake fluid will damage labels, paint and some plastics. Always wipe

up spills immediately.

Replace brake fluid at least every two years.

Brakes

Bleeding the Hydraulic Brake System

Air in the hydraulic brake system will cause spongy brake lever action.
Bleed the system before operating the snowmobile.

WARNING! Operating the vehicle with a spongy brake lever can result in loss of
brakes, which could cause an accident and lead to serious injury or death.
Never operate the vehicle with a spongy-feeling brake lever.

During the bleeding procedure, keep the brake handle as level as
possible. The reservoir must be in this position to minimize the
possibility of air entering the system through the reservoir vent.

1. Remove brake master cylinder reservoir cover and gasket.

2. Fill the master cylinder reservoir to between the MIN and MAX

marks or 1/4-5/16 inch (.6-.8 cm) below the lip of the reservoir
opening. Reinstall the gasket and cover.

3. Slip a rubber tube over the ball of the bleeder valve and direct the

flow of fluid into an approved container.

4. Squeeze the brake lever a full stroke. Then unscrew the bleeder

valve 3/4 of a turn to release air.

5. Close the bleeder valve and release the brake lever.

6. Repeat steps 4 and 5 until fluid flows from the bleeder valve in a

solid stream free of air bubbles.

WARNING! Overfilling the master cylinder leaves no room for fluid expansion
and may cause the brakes to lock, resulting in serious injury or death. Always
add brake fluid to the fill line as recommended.

7. After bleeding is complete, refill the reservoir to the proper level.

8. Reinstall the gasket and cover.

Headlight Adjustment

The headlight may be adjusted for vertical aim using the following
procedure:

1. Place the snowmobile on a level surface with the headlight

approximately 25 feet (7.6 m) from a wall.

2. Measure the distance from the floor to the center of the headlight

and make a mark on the wall.

3. Start the engine and turn the headlight switch to high beam.

4. Observe the headlight aim. The most intense part of the headlight

beam should be aimed two (2) inches (5.1 cm) below the mark
placed on the wall.

Tip: Rider weight must be included on the seat.

5. Turn the adjustment nut, located inside the hood, just below the

headlamp opening. Turn the knob in or out as needed for proper
aim.

MAINTENANCE

Lights

Avoid touching a halogen bulb with bare fingers. Oil from skin leaves a
residue, causing a hot spot that will shorten the life of the lamp. If
fingers do touch the bulb, clean it with an alcohol-moistened towel.

Headlight Bulb Replacement

1. Pinch the ends of the spring (1)

together and lift until it releases
from the spring retainer.

2. Lift the spring carefully around

the wire harness (2) and flip it to
the outside of the housing.

3. With the wire harness attached

to the bulb (3), withdraw the
bulb from the housing.

4. Grasp the bulb by its metal base

and carefully separate the bulb from the harness.

5. Hold the new bulb by its metal base and install it into the wire

harness.

6. Insert the bulb into the housing. Carefully flip the spring back into

the housing, placing it around the wire harness.

7. Squeeze the spring together until it's over the spring retainer and

release.

8. Verify headlight aim. See page 79.

Taillight/Brake Light Replacement

1. Remove the screws (1) securing the

taillight housing (2).

2. Remove and replace the bulb (3).

3. Reassemble all components.
