WARNING
If compressed air, high-pressure water, or steam hits your body directly or dirt is sent flying by the com-
pressed air, high-pressure water, or steam, there is danger of personal injury. Always wear protective
glasses, dust mask, and other protective equipment.
NOTICE
When using compressed air, to prevent damage to the fins, keep a distance from the fins. In particular,
with the aftercooler, if compressed air is directed at an angle of 45°, the nozzle should be at least 300 mm
from the fins.
Avoid directing compressed air at the core perpendicularly as far as possible. If the fins are damaged, it
will cause leakage of water or overheating.
On dusty job sites, carry out this inspection every day, regardless of the maintenance interval.
On the menu for reversing a rotation direction of the hydraulically driven cooling fan in the user menu, the rotation
direction of the fan can be reversed both on the radiator side and on the oil cooler side.
By blowing out wind from the fan toward the outside of the machine, the fan can serve as a cleaner to get rid of
dead insects and dust stuck to the dustproof nets. For more details, see “Fan Reverse Mode (3-70)“.
