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

Whenever routine maintenance is performed on this machine - or at least yearly - inspect all nameplates and labels for legibility. Replace those which are no longer clear. Refer to the parts list for the replacement item number.

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.

WELDER / GENERATOR

MAINTENANCE

STORAGE

Store the Commander in clean, dry protected areas.

CLEANING

Blow out the alternator and controls periodically with low pressure air. do this at least once a week in par- ticularly dirty areas.

BRUSH REMOVAL AND REPLACEMENT

It is normal for the brushes and slip rings to wear and darken slightly. Inspect the brushes when a generator overhaul is necessary.
