ENGINE CONTROLS:

12. RUN/STOP SWITCH - -RUN position energizes the engine prior to starting. STOP position stops the engine. The oil pressure inter- lock 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 approximately 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 mini- mum), 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.ENGINE HOUR METER- Displays the total time that the engine has been running. This meter is useful for scheduling prescribed maintenance.

17.CIRCUIT BREAKER- For protection of Battery Charging Circuit.

18. ELECTRIC FUEL GAUGE- The electric fuel gauge gives accurate and reliable indication as to how much fuel is in the fuel tank.

19. COOLANT TEMPERATURE GAUGE- A indica-

tor of engine coolant temperature.

20.OIL PRESSURE GAUGE- A indicator of engine Oil Pressure.

21.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. After starting the engine the light will go off unless a Low/No battery charge condition exists.

STARTING THE ENGINE

1.Remove all plugs connected to the AC power recepta- cles.

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.
