ENGINE CONTROLS:
12. RUN/STOP SWITCH
- RUN position energizes the
engine prior to starting. STOP position stops the engine.
The oil pressure interlock switch prevents battery drain if
the switch is left in the RUN position and the engine is
not operating.
13. GLOW PLUG PUSH BUTTON
-
• When pushed activates the glow plugs. Glow plug
should not be activated for more than 20 seconds con-
tinuously.
14. START PUSH BUTTON
- Energizes the starter
motor to crank the engine.
15. IDLER SWITCH
- 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 approx-
imately 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 min-
imum), 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.
16. ELECTRIC FUEL GAUGE-
The electric fuel gauge
gives accurate and reliable indication as to how much
fuel is in the fuel tank.
17. ENGINE HOUR METER-
Displays the total time
that the engine has been running. This meter is useful
for scheduling prescribed maintenance.
18. ENGINE PROTECTION LIGHT-
A warning indi-
cator light for Low Oil Pressure and/or Coolant Over
Temperature.The light is off when the systems are func-
tioning properly. The light will come on and the engine
will 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.
19. BATTERY CHARGING LIGHT-
A warning indica-
tor 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 dur-
ing 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.
20. COOLANT TEMPERATURE GAUGE-
A indica-
tor of engine coolant temperature.
21. OIL PRESSURE GAUGE-
A indicator of engine
Oil Pressure.
STARTING THE ENGINE
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.
