In emergencies or when the parking brake must be released on a hill, block the tires carefully before releasing the brake. When the parking brake is released, no braking force can be applied, so check carefully that the situation is safe when moving the machine. If the engine will not run, use the following method to release the parking brake and tow the machine. 1.
