If the machine moves, it will lead to serious injury or death. If machine begins to move during the inspection of braking capacity,
lower the engine speed immediately, set gear shift lever at N position, and then depress the foot brake.
Check the braking capacity of the parking brake as follows.
1. Set the air pressure to the maximum with the machine on flat
ground, and set parking brake valve lever (1) to the PARKING
position.
2. Set gear shift lever (2) to the D position, gradually raise the
engine speed, and check that the machine does not move
even when the engine reaches full speed. If the machine does
not move, it is normal.
3. Lower the engine speed, set gear shift lever at N position. If
any problem is found, ask your Komatsu distributor for repair.
