ENGINE BREAK-IN

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, wetstacking (oil or tar like sub- stance 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 condi- tions for extended periods of time are especially sus- ceptible to the conditions described above. To accomplish successful engine break-in, most diesel- powered equipment needs only to be run at a reason- ably heavy load within the rating of the welder for some period of time during the engine’s 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 suit- able resistive load bank. Note that any attempt to short the output studs by con- necting the welding leads together, direct shorting of the output studs, or connecting the output leads to a length of steel will result in catastrophic damage to the gener- ator and voids the warranty.

2.Set the welder controls for an output cur- rent 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 catastrophic damage to the generator and voids the warranty.

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

Battery Charging

WARNING

GASES FROM BATTERY can explode.

• Keep sparks, flame and cigarettes away.

BATTERY ACID can burn eyes and skin.

• Wear gloves and eye protection and

be careful when boosting, charging or working near battery.

To prevent EXPLOSION when:

a)Installing a new battery - disconnect the negative cable from the old battery first and connect the negative cable to the new battery last.

b)Connecting a battery charger - remove the battery from the welder by disconnecting the negative cable first, then the positive cable and battery clamp. When reinstalling, connect the negative cable last.

c)Using a booster - connect the positive lead to the battery first, then connect the negative lead to the ground lead on the base.

To prevent ELECTRICAL DAMAGE when:

a)Installing a new battery.

b)Using a booster.

Use correct polarity - Negative Ground.

To prevent BATTERY DISCHARGE, if you have an ignition switch, turn it off when engine is not running.

• To prevent BATTERY BUCKLING, tighten nuts on

battery clamp until snug.

The Classic 300 D is equipped with a wet charged battery. The charging current is automatically regulat- ed when the battery is low (after starting the engine) to a trickle current when the battery is fully charged.

When replacing, jumping or otherwise connecting the battery to the battery cables, the proper polarity must be observed. This system is NEGATIVE GROUND.
