ENGINE ADJUSTMENTS

OVERSPEED IS HAZARDOUS

WARNING

The maximum allowable high idle speed for this machine is 3750 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.

Adjustments to the engine are to be made only by a Lincoln Service Center or an authorized Field Service Shop.

SLIP RINGS

A slight amount of darkening and wear of the slip rings and brushes is normal. Brushes should be inspected when a general overhaul is necessary. If brushes are to be replaced, clean slip rings with a fine emery paper.

CAUTION

Do not attempt to polish slip rings while engine is running.

BATTERY

WARNING

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 bat- tery from welder by disconnecting negative cable first, then positive cable and battery clamp. When rein- stalling, connect negative cable last. Keep well venti- lated.

USING A BOOSTER - connect positive lead to battery first then connect negative lead to engine foot.

BATTERY ACID CAN BURN EYES AND SKIN.

• Wear gloves and eye protection and be careful when working near battery. Follow instructions printed on battery.

1.When replacing, jumping, or otherwise connecting the battery to the battery cables, the proper polarity must be observed. Failure to observe the proper polarity could result in damage to the charging circuit. The positive (+) battery cable has a red terminal cover.

2.If the battery requires charging from an external charger, disconnect the negative battery cable first and then the positive battery cable before attaching the charger leads. Failure to do so can result in damage to the internal charger components. When reconnecting the cables, connect the positive cable first and the negative cable last.
