Maintenance
Brakes
Under normal operation, the diaphragm extends into the reservoir as fluid level drops. If the
fluid level is low and the diaphragm is not extended, a leak is likely and the diaphragm
should be replaced. To ensure proper diaphragm operation, always fill the reservoir as
needed whenever the cover is loosened or removed. Do not overfill.
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.
Both brakes are self-adjusting, but the following checks are recommended to keep the brake
systems in good operating condition. Check more often if brakes are used heavily under nor-
mal operation.
