HYDRAULIC OIL DRAIN FILTER CHANGE
For further details on the various maintenance operations, see section “EVERY 500 HOURS”.
DANGER
•
Carry out this check with the machine parked on level
ground and loader arm raised with engaged safety lock.
•
Do not remove the radiator cap when the fluid is hot,
since the fluid may be sprayed out of the radiator and
cause burns.
•
Loosen the cap slowly to release the pressure before re-
moving it.
The radiator cap can be reached after opening the engine hood
(see “3.5.1 ENGINE HOOD”).
Remove the cap (1) and make sure that the fluid is very near the
filling hole.
IMPORTANT
☞
•
If the level of the fluid in the radiator is low and the expan-
sion tank is filled with 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.

the prescribed oil until reaching the MAX. mark (see “4.3 FUEL,
COOLANT AND LUBRICANTS”).
IMPORTANT
☞
•
Use new oil only.
•
If constant and considerable leakages are observed, it is
advisable to contact an Komatsu Utility Dealer to have the
system checked and the necessary repairs carried out.
