have thoroughly read the engine manufacturerʼs
manual supplied with your welder. It includes
important safety precautions, detailed engine
starting, operating and maintenance instructions,
and parts lists.
------------------------------------------------------------------------
ELECTRIC SHOCK can kill.
• Do not touch electrically live parts or
electrode with skin or wet clothing.
• Insulate yourself from work and
ground
• Always wear dry insulating gloves.
------------------------------------------------------------------------
ENGINE EXHAUST can kill.
• Use in open, well ventilated areas or
vent exhaust outside.
------------------------------------------------------------------------
MOVING PARTS can injure.

guards off.
• Stop engine before servicing.
• Keep away from moving parts.
------------------------------------------------------------------------
See additional warning information at the
front of this operatorʼs manual.
------------------------------------------------------------------------
Operate the welder with the doors closed. Leaving
the doors open changes the designed air flow and can
cause overheating.

7. Allow the engine to run at high idle speed for sev-
eral minutes to warm the engine. Stop the engine
and recheck the oil level, after allowing sufficient
time for the oil to drain into the pan. If the level is
down, fill it to the full mark again. The engine con-
trols were properly set at the factory and should
require no adjusting when received.
COLD WEATHER STARTING:
With a fully charged battery and the proper weight oil,
the engine should start satisfactorily even down to
about -15°F (-26°C), it maybe desirable to install cold-
starting aides.
Note: Extreme cold weather starting may require
longer glow plug operation.
WARNING
Under NO conditions should ether or other
starting fluids be used!
------------------------------------------------------------------------
HIGH ALTITUDE OPERATION:
The engine will run correctly up to an altitude of 600m
(2000ft.). If the engine is to be operated permanently
at an altitude above this, the fuel consumption and
exhaust emissions may be excessive.
Contact the Perkins Application Department for any
engine adjustments that may be required.
STOPPING THE ENGINE
1. Turn the "IGNITION" switch to "OFF"
At the end of each dayʼs welding, check the crankcase
oil level, drain accumulated dirt and water from the
water separator located on the fuel rail. Refill the fuel
tank to minimize moisture condensation in the tank.
Also, running out of fuel tends to draw dirt into the fuel
system.
When hauling the welder between job sites, close the
fuel feed valve on the separator located on the fuel
rail.
If the fuel supply is cut off or runs out while the fuel
pump is operating, air may be entrapped in the fuel
distribution system. If this happens, bleeding of the
fuel system may be necessary. Use qualified person-
nel to do this per the instructions in the MAINTE-
NANCE section of this manual.
