COOLING SYSTEM

HOT COOLANT
• Do not remove cap if radiator is hot.
--------------------------------------------------------------------
Check the coolant level by observing the level in the radiator and
recovery bottle. Add 50/50 antifreeze / water solution if the level
is close to or below the "LOW" mark. do not fill above the "FULL"
mark. Remove radiator cap and add coolant to radiator. Fill up to
the top of the tube in the radiator filler neck which includes a
connecting hose coming from the thermostat housing.
To drain the coolant, open the valve at the bottom of the radiator.
Open the radiator cap to allow complete drainage. (Tighten the
valve and refill with a 50/50 antifreeze/water solution.) Use an
automotive grade (low silicate) ethylene glycol antifreeze. The
cooling system capacity is 8.0 quarts (7.6L.). Squeeze upper and
lower radiator hoses while filling to bleed air from system
coolant. Replace and tighten the radiator cap.
Always premix the antifreeze and clean tap water before
adding to the radiator. It is very important that a precise
50/50 solution be used with this engine year round. This
gives proper cooling during hot weather and freezing pro-
tection to -34° F (-37° C).
Cooling solution exceeding 50% ethylene glycol can result in
engine overheating and damage to the engine. Coolant solu-
tion must be premixed before adding to radiator.
----------------------------------------------------------------------------
Periodically remove the dirt from the radiator fins.
Periodically check the fan belt and radiator hoses. Replace if
signs of deterioration are found.
TIGHTENING THE FAN BELT
If the fan belt is loose, the engine can overheat and the battery
lose its charge. Check tightness by pressing on the belt midway
between the pulleys. It should deflect about .25 in.(6.4 mm)
under a load of 20 lbs.(9 Kg).
WARNING
can burn skin.
CAUTION

FUEL

At the end of each day's use, refill the fuel tank to minimize
moisture condensation and dirt contamination in the fuel line.
Do not overfill; leave room for the fuel to expand.
Use only fresh No. 2D diesel fuel, the use of No. 1D diesel fuel is
recommended in place of No. 2D at temperatures below 23°F (-
5°C). Do not use kerosene.
See the Engine Operator's Manual for instructions on replacing
the fuel filter.

BLEEDING THE FUEL SYSTEM

You may need to bleed air from the fuel system if the fuel filter
or fuel lines have been detached, the fuel tank has been ran
empty or after periods of long storage. It is recommended that
the fuel shutoff valve be closed during periods of non-use.
To avoid personal injury, do not bleed a hot engine. This
could cause fuel to spill onto a hot exhaust manifold, creat-
ing a danger of fire.
----------------------------------------------------------------------------
Bleed the fuel system as follows:
1. Fill the fuel tank with fuel.
2. Open the fuel shut off valve.
3. Loosen bleed fitting on the fuel injector manifold.
4. Operate hand priming lever until fuel comes out the bleed
screw on the injector manifold. This could take 20-30 sec-
onds of rapid operation of the priming lever. Tighten bleed fit-
ting on injector manifold.
5. Follow normal STARTING procedures until engine starts.
