BATTERY MAINTENANCE

To access the battery, remove the screws from the rear
battery tray using a screwdriver or a 3/8" socket. Slide
the battery tray out only far enough to access the bat-
tery terminals.
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 bat-
tery 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.
MAINTENANCE
After cleaning, flush the outside of the battery, the bat-
tery compartment, and surrounding areas with clear
water. Coat the battery terminals lightly with petroleum
jelly or a non-conductive grease to retard corrosion.
Keep the battery clean and dry. Moisture accumulation
on the battery can lead to more rapid discharge and
early battery failure.
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.
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 Ranger 250 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 so 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.
