tery.
To prevent EXPLOSION when:
•INSTALLING A NEW BATTERY - disconnect nega- tive 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 reinstalling, connect negative cable last. Keep well ventilated.
•USING A BOOSTER - connect positive lead to bat- tery first then connect negative lead to engine foot.

PREVENTING ELECTRICAL DAMAGE
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 charg- er, 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.
PREVENTING BATTERY DISCHARGE
If you have an ignition switch, turn it off when engine is not running.
PREVENTING BATTERY BUCKLING
Tighten nuts on battery clamp until snug.
NAMEPLATES / WARNING DECALS MAINTENANCE

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 Commander 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 co 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.
