Install the air charge hose for the tire to the air charge socket. 4. Push the end of the hose on the tire valve, and air will be supplied to the brake chamber to release the brake. 5. When the parking brake is released, remove the air charge hose. Tow the machine immedi- ately to a safe place.
A Stop the machine on a flat sur- face when releasing the park- ing brake, and check that the surroundings are safe. In emer- gencies or when the parking brake must be released on a hill, block the tires carefully before releasing the brake. A If there is a failure in the air circuit, the brakes cannot be used. This is dangerous, so always tow the machine at low speed. Keep the engine running so that the steering can be used. * Contact your Komatsu distributor for details. To chamber - 60 - ww -02050
