Clean Radiator/Oil Cooler Cores and Other Cooling
System --- every 500 hours or when the core is
clogged.
WARNING: When using compressed air pressure [less
than 0.2 MPa (2 kgf/cm
gles.
IMPORTANT: If compressed air with the pressure of more
than 0.2 MPa (2 kgf/cm
high delivery pressure is used for cleaning,
damage to the radiator/oil cooler fins may
result. Keep the nozzle away from the core
surface more than 500 mm.
Push down open/close lever (1) inside the engine compart-
ment. Side cover (2) at the radiator can be opened.
(Over the side cover)
Check and clean engine intercooler (3), air condenser (4),
and torque converter oil cooler (5). Locations of catch le-
ver (6) and other cooling equipment differ depending on
machine models. When torque converter oil cooler (5) is
dislocated by pushing down catch lever (6), clearance (10) in
front of the radiator can be cleaned.
(Over the rear grille)
Check and clean radiator (7), hydraulic oil cooler (8), and hy-
draulic driven fan (9).
In case dirt or dust has adhered to the radiator/oil cooler
cores, clean the radiator/oil cooler cores with compressed
air pressure [less than 0.2 MPa (2 kgf/cm
prevent the cooling system performance from being re-
duced.
IMPORTANT: Before operating the fan reverse rotation
switch, stop the engine. Then, after turning
the fan reverse rotation switch ON, start the
engine. When stopping the fan, first stop the
engine. Then, turn the fan reverse rotation
switch OFF. While the engine is running, nev-
er operate the fan reverse rotation switch.
Damage to the fan motor may result.
Operating the fan reverse rotation switch on the right con-
sole can conduct brief cleaning. Keep any personnel away
