Radiator/Oil Cooler
The Radiator and Oil Cooler
must be kept clean to ensure
proper operation. Engine and
hydraulic system overheating,
damage and even failure can
result if the radiator/oil cooler is
not kept clean. A pressure wash-
er or compressed air nozzle
work well to blow debris clear of
the fins in the oil cooler and radi-
ator.
Note:
If hydraulic oil or engine
coolant temperature gauges
indicate abnormally high temper-
atures during operation,
increase cleaning intervals.
Note:
In brush cutting applica-
tions check and clean the cool-
ers often to avoid overheating.
To clean radiator/oil cooler:
1.
Make sure the engine is
off,
and cool
.
2.
Using compressed air or a
pressure washer, thoroughly
clean radiator/oil cooler as
shown.
Note:
Make sure water nozzle is
at least 12” (8” for air) from the
cooler and that the spray is
directed straight through the
cooler or the cooling fins may be
damaged (bent over) which will
decrease cooling performance.
Engine
Periodic cleaning of the chas-
sis area beneath the cab and
engine compartment are also
necessary to maintain safe oper-
ation. Clean as required.
1.
Remove the belly pans on
the underside of the
machine.
2.
Tilt the cab up and raise
the hood at the rear of the
machine.
3.
Pressure wash any debris
from the engine compart-
ment and chassis area out
through the lower opening.
