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 bat- tery 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.

•Open oil drain valve by lifting up spring loaded lever

and rotate 90° counterclockwise. Pull to open and drain the oil into a suitable container for disposal.

•Close the drain valve by rotating lever 90° clockwise.

•Re-fill the crankcase to the upper limit mark on the dipstick with the recommended oil (see engine oper- ation manual OR engine service items decal OR below). Replace and tighten the oil filler cap secure- ly.

•Push oil drain hose and valve back into unit, re-con- nect 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 sta- tion 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 classifi- cations.)

SAE 10W30 is recommended for general, all tempera- ture use, 5F to 104F (-15C to 40C).

See engine owner’s manual for more specific informa- tion 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 con- tacts 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 neces- sary, 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.
