2. If the brake fluid is below the high
brake fluid mark, add Yamaha
approved DOT 4 brake fluid until
the fluid is at the recommended
level. Install and secure the reservoir
cover. Do not allow moisture to con-
taminate the brake system.
CAUTION
Brake fluid is highly corrosive. Do
not spill brake fluid on any surface
of the snowmobile.
WARNING
Do not overfill the brake fluid reser-
voir. Overfilling the reservoir may
cause the brake system to hydrauli-
cally lock. Use
approved DOT 4 brake fluid. Never
substitute or mix different types or
grades of brake fluid. Brake loss
can result. Brake loss can result in
severe injury or even death.
Changing Brake Fluid
The brake fluid must be changed on a
regular basis and whenever the brake
fluid has been overheated or contami-
nated. The brake fluid should be changed
every 1600 km (1000 miles) or at the end
of the snowmobiling season, whichever
occurs first. Take the snowmobile to an
authorized Yamaha Snowmobile dealer
for this service. This service is at the dis-
cretion and expense of the snowmobile
owner.
