PRE-OPERATION SERVICE
READ the engine operating and maintenance instruc-
tions supplied with this machine.

Oil

This unit is supplied from the factory with the engine
crankcase filled with a high quality SAE 10W/30 oil.
This oil should be acceptable for most typical ambient
temperatures. Consult the engine operation manual
for specific engine manufacturer’s recommendations.
Upon receipt of the welder, check the engine dipstick
to be sure the oil is at the “full” mark. DO NOT overfill.

Fuel

Fill the fuel tank with the grade of fuel recommended
in the Engine Operator’s manual. Make sure fuel
valve on the sediment bowl is in the open position.

Cooling System

The radiator has been filled at the factory with a 50-50
mixture of ethylene glycol antifreeze and water.
Check the radiator level and add a 50-50 solution as
needed (see engine manual or antifreeze container for
alternate antifreeze recommendations).

Battery Charging

The Classic III & Classic III D are each equipped with
a wet charged battery. The charging current is auto-
matically regulated when the battery is low (after start-
ing the engine) to a trickle current when the battery is
fully charged.
When replacing, jumping or otherwise connecting the
battery to the battery cables, the proper polarity must
be observed. This system is NEGATIVE GROUND.
CAUTION
Fuel can cause fire or explosion.
-
• Stop engine while fueling.
• Do not smoke when fueling.
• Do not overfill tank.
• Keep sparks and flame away from tank.
• Wipe up spilled fuel and allow fumes to clear
before starting engine.

b) 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.

the battery first, then connect the negative lead to
the ground lead on the base.

To prevent ELECTRICAL DAMAGE when:

a) Installing a new battery.
b) Using a booster.

To prevent BATTERY DISCHARGE, if you have an
ignition switch, turn it off when engine is not
running.
