OPERATION EXPLANATION OF COMPONENTS
ENGINE OIL LEVEL CAUTION LAMP
Engine oil level caution lamp warns about drop of engine lubri-
cating oil level.
It displays only while the engine is stopped.
If the caution lamp lights up in yellow and action level "L01" is
displayed, check the oil level in the oil pan and add oil.
For the method to check the oil level in the oil pan, see "METH-
OD FOR CHECKING OIL LEVEL IN ENGINE OIL PAN, ADD-
ING OIL (3-173)".
If the oil level drops again in a short time, the engine oil may be
leaking. Ask your Komatsu distributor for inspection and repair.
ENGINE OVERRUN CAUTION LAMP
The engine overrun caution lamp warns the operator that the
engine speed is higher than the allowable range.
When the caution lamp lights up in red, the centralized warning
lamp lights up and the alarm buzzer sounds intermittently.
If the engine speed increases more, action level "L02" is dis-
played.
Operate the machine with moderate engine speed and travel
speed.

Radiator coolant level caution lamp warns about drop of radia-
tor coolant level.
If the caution lamp lights up in yellow and action level "L01" is
displayed, check the coolant level in the reservoir tank and add
coolant.
See "METHOD FOR CHECKING COOLANT LEVEL, ADDING
COOLANT (3-172)".
If it occurs again in a short time, the coolant may be leaking
from the radiator. Ask your Komatsu distributor for inspection
and maintenance.
CHARGE LEVEL CAUTION LAMP
Charge level caution lamp warns about abnormality in the
charging system while the engine is running.
If the battery is not charged properly while the engine is run-
ning, the caution lamp lights up in red.

tralized warning lamp lights up and the alarm buzzer sounds in-
termittently.
