FUEL

At the end of each day’s use, refill the fuel tank

to minimize moisture condensation and dirt contami- nation in the fuel line. Do not overfill; leave room for the fuel to expand.

Use only fresh, No. 2 grade DIESEL fuel. Do not use kerosene.

See the Kubota Engine Operator's Manual for instruc- tions on replacing the fuel filter.

BLEEDING THE FUEL SYSTEM

You will need to bleed air from the fuel system any time the fuel filter or fuel lines have been detached and refitted; after the fuel tank has been run out of fuel; or before using the engine after long storage. Bleed the fuel system as follows:

WARNING

To avoid personal injury, do not bleed a hot engine. This could cause fuel to spill onto a hot exhaust mani- fold, creating a danger of fire.

------------------------------------------------------------------------

Refer to Figure D.2

1.Fill the fuel tank, Open the fuel cock.

2.Open the air vent plug on the fuel injection pump two turns using a 10mm wrench.

3.Move the fuel feed pump lever by hand until fuel flows out of the air vent plug.

4.Tighten the air vent plug.

AIR VENT PLUG

AIR CLEANER

The Kubota diesel engine is equipped with a dry type air filter. Never apply oil to it. Service the air cleaner as follows:

1.Remove the dust cup from the bottom of the air cleaner housing. Clean out any accumulated dust.

2.If dust is sticking to the element, blow compressed air through the element from the inside out. Turn the element as you apply air. Air pressure should be under 99 psi (68 newton/cm2). Replace the fil- ter if there is carbon or oil on the element.

3.Replace the element at least every 600 hours of operation and sooner under dusty conditions.

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 bout .25 in. under a load of 20 lbs. (9 Kg) (6 mm).

COOLING SYSTEM

WARNING

HOT COOLANT can burn skin.

• Do not remove cap if radiator is hot.

FUEL BLEEDING COMPONENT LOCATIONS

Check the coolant level by observing the level in the plastic reserve overflow tank. 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 if overflow tank is empty.

To drain the coolant, open the petcock at the bottom or the radiator. Open the radiator cap to allow com- plete drainage. (Tighten the petcock and refill with a 50/50 antifreeze/water solution.) Use an automotive grade (low silicate) ethylene glycol antifreeze. The cooling system capacity is 5.4 quarts (5.1L.). Replace and tighten the radiator cap.
