FEATURES AND CONTROLS Master Cylinder/Brake Fluid Check the brake fluid in the master cylinder before each ride. The fluid level can be seen through an indicator window on the top of the master cylinder. This eye will appear dark when the fluid level is full. When fluid is low, the eye will be clear. NOTE: When checking the fluid level, the ATV must be on level ground with the handlebars straight. Master Cylinder Indicator Window If the fluid level is low add DOT 4 brake fluid only. See page 137 for the part numbers of Polaris products. WARNING An over-full master cylinder may cause brake drag or brake lock-up, which could result in serious injury or death. Maintain brake fluid at the recommended level. Do not overfill. WARNING 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 accident or severe injury. After opening a bottle of brake fluid, always discard any unused portion. 40
