PRE-OPERATION SERVICE
READ the engine operating and maintenance instructions
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 the fuel valve on the water
separator 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).
POLARITY CONTROL AND CABLE SIZES
With the engine off, route the electrode and work cables through
the strain relief bracket on the base and connect to the studs
located below the fuel tank mounting rail. (See size recommen-
dations below.) For
positive
polarity, connect the electrode
cable to the terminal marked
“+”
. For
Negative
polarity, con-
nect the electrode cable to the
“-”
stud. These connections
should be checked periodically and tightened if necessary.
When welding at a considerable distance from the welder, be
sure you use ample sized welding cables.
