engine.

•Do not overfill tank, fuel expansion may cause over- flow.

DIESEL FUEL ONLY

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

Fill the fuel tank with clean, fresh diesel fuel. The capacity of the fuel tank is 22.5 gallons (85.1 liters). See engine Operatorʼs Manual for specific fuel recom- mendations.

Note: Before starting the engine, be sure the fuel shut- off valve is in the open position.

ENGINE COOLING SYSTEM

The cooling system has been filled at the factory with a 50-50 mixture of ethylene glycol antifreeze and water. Check the radiator level and add a 50-50 solu- tion as needed. (See Engine Manual or antifreeze container for alternate antifreeze recommendation.)

ENGINE BREAK-IN PERIOD

Lincoln Electric selects high quality, heavy-duty indus- trial engines for the portable welding machines we offer. While it is normal to see a small amount of crankcase oil consumption during initial operation, excessive oil use, wet stacking (oil or tar like substance at the exhaust port), or excessive smoke is not normal.

Larger machines with a capacity of 350 amperes and higher, which are operated at low or no-load conditions for extended periods of time are especially susceptible to the conditions described above.

To accomplish successful engine break-in, most diesel-powered equipment needs only to be run at a reasonably heavy load within the rating of the welder for some period of time during the engineʼs early life. However, if the welder is subjected to extensive light loading, occasional moderate to heavy loading of the engine may sometimes be necessary. Caution must be observed in correctly loading a diesel/generator unit.

1.Connect the welder output studs to a suitable resis- tive load bank. Note that any attempt to short the output studs by connecting the welding leads together, direct shorting of the output studs, or con- necting the output leads to a length of steel will result in catastrophic damage to the generator and voids the warranty.

2.Set the welder controls for an output current and voltage within the welder rating and duty cycle. Note that any attempt to exceed the welder rating or duty cycle for any period of time will result in cata- strophic damage to the generator and voids the warranty.

3.Periodically shut off the engine and check the crankcase oil level.

WARNING

BATTERY CONNECTION

Use caution as the electrolyte is a strong acid that can burn skin and damage eyes.

Remove and discard the insulating caps from the

negative battery terminals. Attach and tighten negative battery cable termi- nals.

NOTE: This machine is furnished with wet charged batteries; if unused for several months, the batteries

WARNING

may require a booster charge. Be careful to charge the batteries with the correct polarity. Make sure that the batteries are level while charging.

GASES FROM BATTERY can explode.

●Keep sparks, flame and cigarettes away from battery.

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

To prevent EXPLOSION when:

●INSTALLING A NEW BATTERY — disconnect negative cable from old battery first and connect to new battery last.

●CONNECTING A BATTERY CHARGER — remove battery from welder by disconnecting negative cable first, then positive cable and battery clamp. When reinstalling, connect
