EXCESSIVE LEVER TRAVEL
Hydraulic brakes are self-adjusting, but if excessive brake pad clearance
develops, bring the snowmobile to an authorized POLARIS dealer for inspection
and adjustment.
BRAKE FLUID
Replace brake fluid at least every two years with POLARIS DOT 4 high
temperature brake fluid, or an equivalent product.
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 serious injury.
WARNING
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.
NOTICE
Brake fluid will damage labels, paint and some plastics. Always wipe up spills
immediately.
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.
CAUTION
Hot exhaust system parts can cause burns. Allow adequate time for the
exhaust system to cool. Never perform this procedure with the engine running.
