BATTERY MAINTENANCE

GASES FROM BATTERY can explode.

• Keep sparks, flame, and cigarettes away

from battery.

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.

To prevent EXPLOSION when:

• INSTALLING A NEW BATTERY - Disconnect the

negative cable from the old battery first and connect
to the new battery last.

• THE CORRECT POLARITY IS NEGATIVE

GROUND - Damage to the engine alternator and
the printed circuit board can result from incorrect
connection.

• 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.

• To prevent BATTERY BUCKLING, tighten the nuts on

the battery clamp until snug.

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 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 SPECIFIC GRAVITY

Check each battery cell with a hydrometer.

A fully

charged battery will have a specific gravity of 1.260.
Charge the battery if the reading is below 1.215.

NOTE: Correct the specific gravity reading by adding
four gravity points (0.004) for every five degrees the
electrolyte temperature is above 80 degrees F (27
degrees (C).

Subtract four gravity points (.004) for

every five degrees the electrolyte temperature is below
80 degrees F (27 degrees C).

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

The Classic I is equipped with a wet charged battery.
The charging current is automatically regulated when
the battery is low (after starting the engine) to a trickle
current when the battery is fully charged.

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 Classic I charging system is NEGATIVE
GROUND. The 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.
