%&+: When starting for the first time, or after and extended
period of time of not operating, it will take longer than normal to
start because the fuel pump has to fill the fuel system. For best
results, bleed the fuel system as indicated in Maintenance
Section of this manual.

engine prior to starting. STOP position stops the
engine. The oil pressure interlock switch prevents bat-
tery drain if the switch is left in the RUN position and
the engine is not operating.

 #)*. +- Has two positions as follows:
1) In the HIGH position, the engine runs at the high
idle speed controlled by the engine governor.
2) In the AUTO position, the idler operates as
follows:
• When switched from HIGH to AUTO or after starting the
engine, the engine will operate at full speed for approxi-
mately 12 seconds and then go to low idle speed.
• When the electrode touches the work or power is drawn
for lights or tools (approximately 100 Watts minimum), the
engine accelerates and operates at full speed.
• When welding ceases or the AC power load is turned off, a
fixed time delay of approximately 12 seconds starts. If the
welding or AC power load is not restarted before the end
of the time delay, the idler reduces the engine speed to
low idle speed.
• The engine will automatically return to high idle speed
when there is welding load or AC power load reapplied.
#+)  ,# ,The electric fuel

light for Low Oil Pressure and/or Coolant Over

shutdown when there is Low Oil Pressure and/or the
Coolant is Over Temperature.
Note: The light remains off when the RUN-STOP switch is in
the "ON" position prior to starting the engine.However if the
engine is not started within 60 seconds the light will come
on. When this happens the RUN-STOP switch must be
returned to the "OFF" position to reset the engine protection
system and light.
++)0) %# + A warning
indicator light for Low/No battery charge. The light is
off when the systems are functioning properly. The light will
come on if there is a Low/No battery condition but the
machine will continue to run.
Note: The light may or may not come on when the RUN-STOP
switch is in the "ON" position. It will come on during cranking
and stay on until the engine starts. After starting the engine the
light will go off unless a Low/No battery charge condition exists.

1. Remove all plugs connected to the AC power receptacles.
2. Set IDLER switch to AUTO.
3. Press Glow Plug Button and hold 15 to 20 seconds.
4. Set the RUN/STOP switch to RUN.
5. Press START button until the engine starts or for up to 10
seconds. Continue to hold the glow plug button for up to an
additional 10 seconds.
6. Release the engine START button immediately when the
engine starts.
7. The engine will run at high idle speed for approximately 12
seconds and then drop to low idle speed. Allow the engine to
warm up at low idle for several minutes before applying a
load and/or switching to high idle. Allow a longer warm up
time in cold weather.
%&+: If the unit fails to start turn run/stop switch to off and
repeat step 3 through step 7 after waiting 30 seconds.
