Refill the crankcase with the specified amount of the
recommended engine oil. Reinstall the oil filler cap
and tighten securely.
Start the engine and check for oil filter leaks.
Stop the engine and check the oil level. If
necessary, add oil to the upper limit mark on the
dipstick.
WARNING
Never use gasoline or low flash point solvents for
cleaning the air cleaner element. A fire or explosion
could result.
WARNING
Never run the engine without the air cleaner. Rapid
engine wear will result from contaminants, such as dust
and dirt being drawn into the engine.
Air Cleaner
The diesel engine is equipped with a dry type air filter.
Never apply oil to it. Service the air cleaner as follows:
Replace the element at least every 200 hours of
operation and sooner under dusty conditions.
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 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 3.6l. Squeeze upper and lower radiator hoses while
filling to bleed air from system coolant. Replace and
tighten the radiator cap.
WARNING
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
protection to -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 pressing on
the belt midway between the pulleys. It should deflect
about 6mm under a load of 9 Kg.
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. 2 grade DIESEL fuel. 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.
The Kubota D722 engine supplied with this welder is
equipped with an automatic bleeding mechanism that
helps purge the air from the mechanical fuel pump
system. It is generally not necessary to open a vent
screw or fuel line fitting to bleed the fuel system.
Operate the priming lever on the pump to assist starting
after extended periods of non-use or out of fuel
conditions.
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:
Fill the fuel tank with fuel.
Open the fuel shut off valve (vertical position of
handle) on the Fuel Filter.
Crank the engine by pressing the start button for 45
seconds.
Check to see that fuel is flowing through both fuel
filters.
Follow the normal STARTING procedures.
Fuel Filter
Check the fuel filter and fuel pre-filter for water
accumulation or sediment.
Replace the fuel filter if it is found with excessive
water accumulation or sediment. Empty fuel pre-
filter.
WARNING
OVERSPEED IS HAZARDOUS.
The maximum
allowable high idle speed for this machine is 3150 RPM,
no load. Do NOT tamper with governor components or
setting or make any other adjustments to increase the
maximum speed. Severe personal injury and damage to
the machine can result if operated at speeds above
maximum.
