Every six months the drain plugs should be removed
from the tanks so that any sediment or accumulated
condensate may be drained. When replacing the
drain plugs, make sure they are tightened securely.
BATTERY
Heavy--duty, diesel cranking type batteries were
installed at the factory and these should be
inspected weekly. Keep the battery posts--to--cable
connections clean, tight and lightly coated with a
grease. Also the electrolyte level in each cell should
cover the top of the plates. If necessary, top--up with
clean distilled water.
COMPRESSOR OIL and FUEL COOLERS
The coolers are cooled by means of the fin and
tube--type oil cooler. The compressor oil and fuel
flow internally through the core sections. Fluid is
cooled by the air stream from the cooling fan flowing
past the core section. When grease, oil and dirt
accumulate on the exterior surfaces of the coolers,
their efficiency is impaired.
Each month it is recommended that the coolers be
cleaned by directing compressed air which contains
a nonflammable safety solvent through the core of
the coolers. This should remove the accumulation of
grease, oil and dirt from the exterior surfaces of the
cooler core so that the entire cooling area can
transmit the heat of the fluid to the air stream.
If foreign deposits, such as sludge and lacquer,
accumulate in the coolers, high temperature is likely
to occur, causing shut down of the unit.
RADIATOR
WARNING
Do not remove the cap from a HOT engine
radiator. The sudden release of pressure from a
heated cooling system can result in serious
personal injury.
The engine cooling system is filled at the factory with
a 50/50 mixture of water and ethylene glycol. This
permanent type antifreeze contains rust inhibitors
and provides protection to --35
°
F (--37
°
C).
The use of such a mixture is recommended for both
summer and winter operation. When using water
alone, be sure to add a reputable brand of rust
inhibitor to prevent internal corrosion.
It is recommended to test the freezing protection of
the coolant every six months or prior to freezing
temperatures. Replenish with a fresh mixture every
twelve months. A drain for the system is located in
the bottom radiator tank.
Each month, inspect the radiator exterior for
obstructions (dirt, bugs, etc.). If present, blow water
or compressed air containing a nonflammable
solvent between the fins in a direction opposite the
normal air flow. Should the radiator be clogged
internally, standard automotive practices should be
followed.
ENGINE CHARGE AIR COOLER
This cooler is a fin and tube--type oil cooler. The
engine intake air flows internally through the core
section. It is cooled by the air stream from the cooling
fan flowing past the core section. When grease, oil
and dirt accumulate on the exterior surfaces of the
cooler, efficiency is impaired.
Each month it is recommended that the cooler be
cleaned by directing compressed air which contains
a nonflammable safety solvent through the core of
the cooler. This should remove the accumulation of
grease, oil and dirt from the exterior surfaces of the
cooler core so that the entire cooling area can
transmit the heat of the fluid to the air stream.
Ensure that the air connections do not leak. Leaks or
loss of cooling will result in low engine power.
