ENGINE ADJUSTMENT
Adjustments to the engine are to be made only by a
Lincoln Service Center or an authorized Field Service
Shop.
BATTERY MAINTENANCE
To access the battery, remove the battery tray from
the front of the machine with 3/8” nut driver or flat
head screw driver. Pull the tray out of machine far
enough to disconnect the negative and then positive
battery cables. The tray can then be tilted and lifted to
remove the entire tray and battery from the machine
for easy service.
GASES FROM BATTERY can explode.
• Keep sparks, flame and cigarettes
away from battery.
To prevent EXPLOSION when:
• INSTALLING A NEW BATTERY —
disconnect negative cable from old
battery first and connect to new
battery last.
• CONNECTING A BATTERY CHARGER —
remove battery from welder by disconnecting
negative cable first, then positive cable and
battery clamp. When reinstalling, connect
negative cable last. Keep well ventilated.
• USING A BOOSTER — connect
positive lead to battery first then
connect negative lead to negative
battery lead at engine foot.
BATTERY ACID can burn eyes and skin.
• Wear gloves and eye protection and be careful
when working near battery.
• Follow instructions printed on 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
(0.1113kg) of baking soda and 1 quart (0.9461L) of
water.

OVERSPEED IS HAZARDOUS
The maximum allowable high idle speed for this
machine is 1850 RPM, no load. Do NOT tamper
with governor components or setting or make any
other adjustments to increase the maximum
speed. Severe personal injury and damage to the
machine can result if operated at speeds above
maximum.
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 accumula-
tion on the battery can lead to more rapid discharge
and early battery failure.
CHECKING THE 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 con-
nect battery cables to the battery, be sure the polarity
is correct. Improper polarity can damage the charging
circuit. The AIR VANTAGE
® 500(AU) KUBOTA posi-
tive (+) 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.
SERVICING MUFFLER WITH INTER-
NAL SPARK ARRESTOR
Clean every 100 hours. Remove screw plug on muf-
fler body and either vacuum out OR shake out until
clean.
