MAINTENANCE

CHECK BRAKING CAPACITY OF PARKING BRAKE

If the machine moves, it will lead to serious injury. If machine begins to move during the inspection of braking capacity, lower the
engine speed immediately, set shifting lever at N position, and then depress the foot brake.
Check the braking capacity of the parking brake as follows.
1. Stop the machine on flat ground and set parking brake switch
(1) to PARKING.
2. Set shift lever (2) to the D position, gradually raise the engine
speed. If the machine does not move even when the engine
speed reaches 1400 rpm, 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.
NOTICE
There is danger of damage inside the transmission, so always do this with the shift lever at the "D" position. Do not use any other
position.
