Precautions regarding brake function
When traveling long distances continuously downhill, the fre-
quency of using the brake may increase. As a result, depending
on the weight of the machine and the grade of the slope, the
machine's braking capacity may be exceeded and the brakes
may overheat.
The table below shows a guideline of the values for this
machine.
If the braking capacity limit is exceeded, a forced cooling system
for the brakes is needed, so please consult your KOMATSU dis-
tributor.
