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 bat- tery 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 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.
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 indicator light for Low Oil Pressure and/or Coolant Over Temperature.The light is off when the systems are function- ing 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
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
20. COOLANT TEMPERATURE GAUGE-A indicator of
engine coolant temperature.
21.OIL PRESSURE GAUGE- A indicator of engine Oil Pressure.
22.CIRCUIT bREAKER- For protection of Battery Charging Circuit.
23.CIRCUIT bREAKER- For protection of 42V Wire Feeder circuit.
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.
NOTE: If the unit fails to start turn run/stop switch to off and repeat step 3 through step 7 after waiting 30 seconds.
CAUTION
•Do not allow the starter motor to run continuously for more than 20 seconds.
• Do not push the START button while the engine is run- ning because this can damage the ring gear and/or the starter motor.
• IF the Engine Protection or battery Charging Lights do “not” turn off shortly after starting the engine shut off the engine immediately and deter mine the cause.
NOTE: 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.
