DANGER
•
Carry out this check with the machine parked on a level
surface and the equipment resting on the ground.
•
Do not remove the radiator cap when the fluid is hot, since
the fluid may be sprayed out violently and cause burns.
•
Loosen the cap slowly in order to release the pressure be-
fore removing it.
The radiator cap can be reached by opening the engine hood
(see “3.5.1 ENGINE HOOD”).
Remove the cap (1) and make sure that the fluid level reaches the
filling hole.
IMPORTANT
☞
•
If the fluid level in the radiator is low and the expansion
tank is full of coolant, check the tightness and make sure
that there are no air leaks from the coupling that connects
the radiator and the expansion tank.
If the problem persists, contact your Komatsu Utility Deal-
er.
