WARNING:
 Use reduced compressed air pressure. (Less than
0.2 MPa, 2 kgf/cm
against flying chips, and wear personal protection
equipment including goggles or safety glasses.
 Entanglement in moving parts can cause serious
injury.
 Before servicing, stop the engine and the fan to
prevent any accident.
 Never attempt to start the engine when the cover is
open.
 In case tools or parts are dropped into the radiator/
oil cooler/inter cooler core, remove them before
starting the engine.
IMPORTANT:
 Cover the air cleaner inlet opening to prevent the
entry of dust and water while cleaning the radiator.
 If air with pressure of higher than 0.2 MPa (2 kgf/cm
or tap water with high delivery pressure is used for
cleaning, damage to the radiator/oil cooler/ fins may
result. Use the nozzle at 500 mm or more from the
object.
 Check the core periodically and replace it if
necessary when the machine is operated in dusty
areas.
The radiator and the oil cooler are arranged in parallel.
If dirt or dust is accumulated on the radiator core, clean them
with compressed air pressure or tap water. Clean the oil cooler
side at this time. It will prevent a reduction in cooling system
performance.
