ENGINE OPERATION
WARNING
Do not attempt to use this equipment until you
have thoroughly read the engine manufacturer's
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.
• Do not operate with doors open or
guards off.
• Stop engine before servicing.
• Keep away from moving parts.
------------------------------------------------------------------------
See additional warning information at the
front of this operator's manual.
------------------------------------------------------------------------
Operate the welder with the doors closed. Leaving the
doors open changes the designed air flow and can
cause overheating.
STARTING THE SAE-300
DIESEL ENGINE
1. Turn the "IDLER" switch to "HIGH".
2. Turn the "IGNITION" switch to "ON".
3. Press the Glow Plug button for 20 to 30 seconds.
(maximum 60 seconds).
4. Press the Start button. When the engine starts run-
ning, release both buttons. If the engine fails to start
in 20 seconds, wait 30 seconds and repeat the
above procedure.
5. Observe the oil pressure. If no pressure shows
within 30 seconds, stop the engine and consult the
engine operating manual. To stop the engine, turn
the "IGNITION" switch to "OFF".
6. If the engine protection warning light comes on dur-
ing cranking or after start up, the "IGNITION" switch
must be turned "OFF" to reset the engine protection
system.

OPERATION

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
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 day's 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.
® 404D-22
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 dis-
tribution system. If this happens, bleeding of the fuel
system may be necessary. Use qualified personnel to
do this per the instructions in the MAINTENANCE sec-
tion of this manual.
