Features and Controls
Parking Brake
The parking brake may relax if left on for a long period of time. Always block the wheels to
prevent rolling. Always block the wheels on the downhill side of the ATV if leaving it parked
on a hill. Another option is to park the ATV in a sidehill position. Never depend on the park-
ing brake alone if the ATV is parked on a hill. Always block the wheels to prevent rolling.
