12.1.2 CHECK BEFORE STARTING
Always carry out the items in this section before starting the
engine each day.
CHECK BULBS OF PILOT LAMPS
1.
Turn the key in starting switch to the ON position.
2.
When each pilot lamp
1
lights on, bulbs are no problem.
3.
When each lamp doesn’t light, contact your Komatsu distributor
for service.
The preheating pilot lamp lights up only when the starting switch
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.
CHECK COOLANT LEVEL, ADD WATER

Normally, do not open the radiator cap. Always wait for the
engine to cool down before checking the water level, and check
using the sub-tank.

Open the engine side cover at the rear left side of the machine,
and check that the coolant level is between the FULL and LOW
marks on sub-tank
1
. If the coolant level is low, add water to the
FULL level through the water filler in sub-tank
1
.
2.
After adding water, tighten the cap securely.
3.
If sub-tank
1
is empty, check for water leakage, then add water
to the radiator and sub-tank.
