MAINTENANCE
CLEAN RADIATOR FINS
1. Remove bolts (1) at the four corners of the radiator grill, then
open radiator grill (2).
2. Clean the radiator fins clogged with mud, dust and leaves with
compressed air. Steam or water may be used instead of
compressed air.
REMARK
Check the hydraulic cooler hoses. If any hose is cracked or
hardened by age, replace with a new hose. Also check and tighten
all loose hose clamps.
CLEAN OIL 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) on the right side face of the
radiator guard, then remove cover (1).
2. When cover (1) is removed, there is a cleaning hole. Use this
hole to check and clean hydraulic cooler fins (3).
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 rotate the fan
in reverse and switch the direction of the air flow. Set the fan
reverse mode on the user menu.
The fan reverse rotation speed is 100%, so it can be used to clean
the fins.
When the engine is running, the fan rotation selector switch does
not work.
