Komatsu WA500-6H Operation & Maintenance Manual page 167

Operation
10. After stopping rotation of the fan, open cleaning cover (2).
11. Use compressed air to blow out the dirt to the side of the
machine.
NOTE
If the steam jet nozzle is brought too close the radiator fins, it
may damage the fins, so keep the nozzle a suitable distance
away from the fins when cleaning.
The guideline for the spray pressure is 9.8 MPa {100 kgf/
cm2, 1420 PSI}. With a nozzle diameter of 2 mm (0.1 in),
keep at least 100 mm (3.9 in) away.
REMARK
Steam or water can be used instead of compressed air.
12. After blowing out the dirt, close cleaning cover (2).
13. Turn starting switch key to the ON position.
14. Set cooling fan reverse rotation switch (1) to position (b)
(OFF) to cancel the reverse rotation.
15. Check the rubber hose. Replace with a new one if the hose
is found to have cracks or to be hardened by aging.
Also, check hose clamps for looseness.
