C. FILTERS

RADIATOR SCREEN–
In order to maintain air flow through the engine
cooling system’s radiator, oil cooler, and air conditioning condenser, the cooling
air intake grille (fig. 119-1) must be inspected often and periodically cleaned.
When the engine hood has been opened for servicing, use compressed air
to dislodge most large trash and dirt. Blow out the screen AWAY from the ma-
chine. Water from a pressurized hose may also be used, or if necessary the
screen may be soaked with soapy water and scrubbed gently with a brush.
FIG 119-1
NOTE:
Failure to keep cooling systems clean
can cause over heating and damage to
the hydrostatic system and/or engine.
NOTE:
When cleaning cooling fins of the radiator, oil
cooler, or A/C condenser with compressed
air or water, be careful not to damage cooling
fins which may impair cooling capabilities.
HYDRAULIC FILTER AND STRAINERS–
RETURN FILTER-
Remove and install a new 10 micron rated
return filter (fig. 119-2) at the end of the first 50 hours of use, subse-
quently replace the filter every 250 hours, or once a year, whichever
comes first.
SUCTION STRAINERS–
The suction strainers located inside
of the tank should be examined for wear and blockage when the tank
is empty for fluid service (see page 114).
FILL SCREEN-
Replace the fill screen immediately if there is
any signs of a tear or break. The screen is the first defense against
foreign materials entering the tank.
FIG 119-2
STRAINER BASKET–
There is a strainer basket in the top fill
opening of the solution tank (fig. 119-3). Check the basket for any
debris before using the opening to fill the tank. Do not remove the
strainer except for cleaning.
