COOLING SYSTEM
WARNING
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.
CAUTION
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
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
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
WARNING
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
2.Replace the fuel filter if it is found with excessive water accumulation or sediment. Empty fuel
