BATTERY MAINTENANCE

WARNING
GASES FROM BATTERY can explode.
• Keep sparks, flame, and cigarettes
away from battery.
To prevent EXPLOSION when:
• INSTALLING A NEW BATTERY - Disconnect the
negative cable from the old battery first and connect
to the new battery last.
• CONNECTING A BATTERY CHARGER -
Remove the battery from the welder by
disconnecting the negative cable first,
then the positive cable and battery
clamp. When reinstalling, connect the
negative cable last. Keep the area well
ventilated.
• USING A BOOSTER - Connect the positive lead to
the battery first, then connect the negative lead to
the engine foot.
BATTERY ACID CAN BURN EYES AND
SKIN.
• Wear gloves and eye protection and be
careful when working near a battery.
Follow the instructions printed on the
battery.

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 (0.113 kg)
of baking soda and 1 quart (0.946 l) 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 petrole-
um jelly or a non-conductive grease to retard corro-
sion.
Keep the battery clean and dry. Moisture accumula-
tion on the battery can lead to more rapid discharge
and early battery failure.
MAINTENANCE

CHECKING 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.
The battery is a group 45, 495 amps cold cranking.

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 10-LX 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 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.
WELDER/GENERATOR
MAINTENANCE
STORAGE: Store the RANGER 10-LX in clean, dry,
protected areas.
CLEANING: Blow out the generator and controls peri-
odically with low pressure air. Do this at least once a
week in particularly dirty areas.
BRUSH REMOVAL AND REPLACEMENT: It's normal
for the brushes and slip rings to wear and darken
slightly. Inspect the brushes when a generator over-
haul is necessary. Remove the brushes and clean the
slip rings with fine emery paper. Refer to the "Brush
Removal and Replacement" procedure in the Trouble-
shooting and Repair section of this manual.
Do not attempt to polish slip rings while the engine is
running.
