engine each day.
CHECK BULBS OF PILOT LAMPS
1. Turn the key in starting switch to the ON position.

3. When each lamp doesn’t light, contact your Komatsu distributor
for service.

is at the HEAT position; the parking brake pilot lamp does not light
up when the parking brake is not applied.
When the parking brake is released, the parking brake reminder
caution lamp lights up and the alarm buzzer sounds.

using the sub-tank.

and check that the coolant level is between the FULL and LOW
marks on sub-tank

FULL level through the water filler in sub-tank 1 .

to the radiator and sub-tank.
