SERVICE PROCEDURE
CLEAN, CHECK HYDRAULIC COOLER FINS
If the hydraulic cooler fins are clogged or there is dirt caught in the fins, clean and check the fins.
1.
Loosen 4 bolts (2) of cover (1) at the left side face of the
radiator guard, then remove cover (1).
2.
When cover (1) is removed, cleaning hole (A) can be seen.
Carry out inspection and cleaning of the hydraulic cooler fins
(3) through this hole.
3.
Use compressed air to blow off the mud, dirt, or leaves
clogging the hydraulic cooler fins. It is also possible to use
steam or water in place of compressed air.
When cleaning the hydraulic cooler, it is possible to reverse the
direction of rotation of the fan to switch the direction of the air flow.
Set the fan rotation selector switch to the CLN (c) position, then
start the engine.
The fan will rotate in reverse at 100 percent speed, so the fins can
be cleaned.
The fan rotation selector switch cannot be used when the engine
is running.
