FUEL FILTER

1.Check the fuel filter and fuel pre-filter for water accu- mulation or sediment.

2.Replace the fuel filter if it is found with excessive water accumulation or sediment. Empty fuel pre- filter.

ENGINE ADJUSTMENT

OVERSPEED IS HAZARDOUS

The maximum allowable high idle speed for this machine is 1890 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.

CLEANING THE BATTERY

Keep the battery clean by wiping it with a damp cloth when dirty. If the terminals appear corroded, discon- nect the battery cables and wash the terminals with an ammonia solution or a solution of 1/4 pound (0.1113 kg) of baking soda and 1 quart (0.9461L) of water. Be sure the battery vent plugs (if equipped) are tight so that none of the solution enters the cells.

After cleaning, flush the outside of the battery, the bat- tery compartment, and surrounding areas with clear water. Coat the battery terminals lightly with petroleum jelly or a non-conductive grease to retard corrosion.

Keep the battery clean and dry. Moisture accumulation on the battery can lead to more rapid discharge and early battery failure.

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

BATTERY MAINTENANCE

To access the battery, remove the battery tray from the front of the machine with 3/8” nut driver or flat head screw driver. Pull the tray out of machine far enough to disconnect the negative and then positive battery cables. The tray can then be tilted and lifted to remove the entire tray and battery from the machine for easy service.

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 bat- tery last.

CONNECTING A BATTERY CHARGER — remove battery from welder by disconnecting negative cable first, then positive cable and battery

clamp. When reinstalling, connect negative cable last. Keep well ventilated.

USING A BOOSTER — connect positive lead to battery first then connect negative lead to nega- tive battery lead at engine foot.

BATTERY ACID can burn eyes and skin.

Wear gloves and eye protection and

be careful when working near bat- tery.

Follow instructions printed on bat- tery.

CHECKING THE ELECTROLYTE LEVEL

If battery cells are low, fill them to the neck of the filler hole with distilled water and recharge. If one cell is low, check for leaks.

CHARGING THE BATTERY

When you charge, jump, replace, or otherwise connect battery cables to the battery, be sure the polarity is cor- rect. Improper polarity can damage the charging cir- cuit. The VANTAGE® 400 positive (+) battery terminal has a red terminal cover.

If you need to charge the battery with an external charger, disconnect the negative cable first, then the positive cable before you attach the charger leads. After the battery is charged, reconnect the positive bat- tery cable first and the negative cable last. Failure to do so can result in damage to the internal charger com- ponents.

Follow the instructions of the battery charger manufac- turer for proper charger settings and charging time.

SERVICING OPTIONAL SPARK ARRESTOR

Clean every 100 hours.

WARNING

MUFFLER MAY BE HOT
