Radiator/Oil Cooler Cleaning

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 washer
or compressed air nozzle work well to blow debris
clear of the fins in the oil cooler and radiator.
Note: If hydraulic oil or engine coolant temperature
gauges indicate abnormally high temperatures during
operation, increase cleaning intervals.
Note: In brush cutting applications check and clean
the coolers often to avoid overheating.
To clean radiator/oil cooler: (fig. 49 & 50)
1. Make sure the engine is off acourding to
descriptio of the operations manual, and
is cool.
2. Wear any appropriate safety clothing.
3. Clean the radiator/oil cooler using compressed air,
or a pressure washer, and direct spray forward as
shown.
Note: Make sure water nozzle is at least 12 in. /
30.5 cm ( 8 in. / 20.3 cm 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.
