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 possi-
ble. 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. 

See page 59.

8. Reinstall the gasket and cover.

Removing Halogen Bulbs

Tip: Do not touch a halogen bulb with bare fingers. Oil from skin leaves a resi-

due, 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.

1. Remove the plenum cov-

ering from the headlight 
assembly. Lift the rubber 
boot to expose the bulb.

2. Push down on the spring 

to release it from the 
housing.

3. With the wire harness 

attached to the bulb, 
withdraw the bulb from 
the housing.

4. Grasp the bulb by its 

metal base and carefully 
separate the bulb from 
the harness.
