FEATURES AND CONTROLS
Master Cylinder/Brake Fluid
An over-full master cylinder may cause brake drag or brake lock-up, which could
result in an accident. Maintain brake fluid at the recommended level. Do not
overfill.
Never store or use a partial bottle of brake fluid. 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 brake failure, which could result in an accident. After
opening a bottle of brake fluid, always discard any unused portion.
Check the brake fluid in the master
cylinder before each ride.
1. Position the ATV on a level
surface.
2. Position the handlebars so the
master cylinder is level.
3. View the brake fluid level
through the indicator window
on the top of the master cylin-
der. The eye will appear dark
when the fluid level is full.
When fluid is low, the eye will
be clear.
4. If the fluid level is low add DOT 4 brake fluid only. Do not overfill.
