ENGINE ADJUSTMENT

OVERSPEED IS HAZARDOUS

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.

BATTERY MAINTENANCE

To access the battery, Remove the 2 screws from the rear battery tray using a screwdriver or a 3/8" socket. Slide the battery tray out only far enough to access the battery terminals.

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 con- nect 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 negative cable last. Keep well ventilated.

•USING A BOOSTER — connect positive lead to battery first then connect negative lead to neg- ative battery lead at 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 bat- tery.

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 (0.12 kg) of baking soda and 1 quart (0.9461liter) 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 accumula- tion on the battery can lead to more rapid discharge and early battery failure.

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 con- nect battery cables to the battery, be sure the polarity is correct. Improper polarity can damage the charging circuit. The RANGER 250 LPG 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 battery cable first and the negative cable last. Failure to do so can result in damage to the internal charger components.

Follow the instructions of the battery charger manu- facturer for proper charger settings and charging time.

SERVICING OPTIONAL SPARK

ARRESTER

WARNING

Clean every 100 hours.

MUFFLER MAY BE HOT
