RELEASE METHOD WHEN PARKING BRAKE AND SECONDARY BRAKE HAVE BEEN ACTUATED
IN EMERGENCY
If the pressure in the air tank has dropped abnormally because of leakage of air from the air circuit, the parking brake
and secondary brake are applied automatically. After emergency actuation of the brakes, if they are not released,
release the brakes as follows.
METHOD OF RELEASING PARKING BRAKE
Please ask your Komatsu distributor to release the parking brake.
WARNING
If there is a failure in the air circuit, the brakes will not work. It is dangerous to drive the machine in this condition, so always
tow the machine at low speed. When towing, run the engine so that it is possible to steer the machine.
When releasing the parking brake, carry out the operation on flat ground and check that the surrounding area is safe. If the
parking brake must be released on a slope because of an emergency or some other unavoidable reason, put blocks under the
wheels before releasing the brake.
After the parking brake has been actuated in an emergency, if the parking brake is not released when the parking
brake valve lever is set to the TRAVEL position, do as follows to release the parking brake.
1. Remove air charge socket (1) installed to the front air tank.
2. Remove the air hose from parking brake chamber (2), then
install removed socket (1) to chamber (2).
3. Install one end of air charge hose (3) (supplied with the
machine) to air charge socket (1). (The hose and socket can be
installed at a touch.)
4. Push the other end of air charge hose (3) into valve (4) of the
tire. Air is supplied to the parking brake chamber, and the
parking brake is released.
5. When the parking brake is released, tow the machine
immediately to a safe position. For details of the method of
towing, see "METHOD OF TOWING MACHINE (PAGE
3-116)".
