COOLING SYSTEM
HOT COOLANT can burn skin.
• 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 2.6gal. (9.8L). Squeeze upper and
lower radiator hoses while filling to bleed air from sys-
tem 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 dur-
ing hot weather and freezing protection to -34° F (-
37° C).
Cooling solution exceeding 50% ethylene glycol
can result in engine overheating and damage to
the engine. Coolant solution 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 press-
ing on the belt midway between the pulleys. It should
deflect about .25 in.(6.4 mm) under a load of 20 lbs.(9
Kg).
FUEL: Diesel Fuel Only - Low Sulphur Fuel
or Ultra Low Sulphur Fuel in U.S.A. and
CANADA only.
At the end of each day’s use, refill the fuel tank to min-
imize 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 tem-
peratures 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 stor-
age. 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, creating 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 injection pump.
4. Be sure the “Run/Stop” switch is in the OFF posi-
tion. Crank engine for 20 second burst until the
engine starts. Close bleed fitting. Start the engine
and let it run for 5 to 10 minutes to work the air out
of the lines.
5. Follow normal STARTING procedures until engine
starts.
FUEL FILTER
1. Check the fuel filter and fuel pre-filter for water
accumulation or sediment.
2. Replace the fuel filter if it is found with excessive
water accumulation or sediment. Empty fuel pre-fil-
ter.
