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 300 positive (+) battery termi- nal 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 co 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.

MAINTENANCE
STORAGE
Store the RANGER 300 in clean, dry protected areas.
CLEANING
Blow out the generator and controls periodically with low pressure air. do this at least once a week in par- ticularly dirty areas.
OUTPUT RANGE SELECTOR AND
POLARITY SWITCHES:
Switch contacts should not be greased. To keep con- tacts clean, rotate the switch though its entire range frequently. Good practice is to turn the handle from maximum to minimum setting twice each morning before starting to weld.
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.
WARNING
Do not attempt to polish slip rings while the engine is running.
