The park brake is integrated with the steering control levers. Move both levers out from the neutral position to engage the park brake.
To release the park brake, pull both steering control levers inwards to the neutral position at the same time. Do not try to operate the unit without both levers being inwards out of the engaged position or machine components could be damaged.
IMPORTANT INFORMATION: Failure to bring the steering / park brake controls inward at the same time will cause the unit's safety system to shut the unit down.
