roUtine Maintenance
At the end of each day's use, refill the fuel tank to minimize
moisture condensation in the tank. Running out of fuel tends to
draw dirt into the fuel system. Also, check the crankcase oil level
and add oil if indicated.
Engine Oil Change
Drain the engine oil while the engine is warm to assure rapid and
complete draining. It is recommended that each time the oil is
changed the oil filter be changed as well.
• Be sure the unit is off. Disconnect the negative battery cable
to ensure safety.
• Locate oil drain hose and valve in bottom of base and pull
through the hole in the battery access panel on the welder.
• Remove the cap from the drain valve. Push valve in and twist
counterclockwise. Pull to open and drain the oil into a suitable
container for disposal.
• Close the drain valve by pushing in and twisting clockwise.
Replace the cap.
• Re-fill the crankcase to the upper limit mark on the dipstick
with the recommended oil (see engine operation manual OR
engine service items decal OR below). Replace and tighten
the oil filler cap securely.
• Push oil drain hose and valve back into unit, re-connect
negative battery cable, and close doors and engine top cover
before restarting unit.Wash your hands with soap and water
after handling used motor oil. Please dispose of used motor
oil in a manner that is compatible with the environment. We
suggest you take it in a sealed container to your local service
station or recycling center for reclamation. DO NOT throw it in
the trash; pour it on the ground or down a drain.
Use motor oil designed for diesel engines that meets requirements
for API service classification CC/CD/CE/CF/CF-4/CG-4 or CH-4.
ACEA E1/E2/E3. Always check the API service label on the oil
container to be sure it includes the letters indicated. (Note: An S-
grade oil must not be used in a diesel engine or damage may
result. It IS permissible to use an oil that meets S and C grade
service classifications.)
SAE 10W30 is recommended for general, all temperature use, 5F
to 104F (-15C to 40C).
See engine owner's manual for more specific information on oil
viscosity recommendations.
Oil Filter Change
• Drain the oil.
• Remove the oil filter with an oil filter wrench and drain the oil
into a suitable container. Discard the used filter. Note: Care
should be taken during filter removal to not disrupt or damage
in any way the fuel lines.
• Clean the filter mounting base and coat the gasket of the
new filter with clean engine oil.
• Screw the new filter on by hand until the gasket contacts the
mounting base. Using an oil filter wrench, tighten the filter an
additional 1/2 to 7/8 of a turn.
• 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.
CAUTION
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 every 500 hours of operation. Under dusty
conditions, replace sooner.
