RANGER 300 D AND 300 DLX
CHARGING THE BATTERY
When you charge, jump, replace, or otherwise connect
battery cables to the battery, be sure the polarity is
correct. Improper polarity can damage the charging
circuit. The RANGER 300 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.

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.
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.
Do not attempt to polish slip rings while the engine is
running.
NAMEPLATES
Whenever routine maintenance is performed on this
machine - or at least yearly - inspect all nameplates
and labels for legibility. Replace nameplates that are
no longer clear. Refer to the parts list for the replace-
ment item number.
RECEPTACLES
Keep the electrical receptacles in good condition.
Remove any dirt, oil, or other debris from their sur-
faces and holes.
CABLE CONNECTIONS
Check the welding cable connections at the weld out-
put terminals often. Be sure that the connections are
always firm.
