ENGINE CONTROLS

See Figure B.2 for the location of the following fea- tures:

1.GLOW PLUG PUSH-BUTTON: Activates glow plugs to preheat engine for starting.

2.IDLER CONTROL SWITCH: The idler switch has two positions. “HIGH” and “AUTO”.

When in “HIGH” ( ) position, the engine will run continuously at high speed for approximate- ly 8 seconds and then go to high speed.

When in “AUTO” ( / ) idle position, the idler operates as follows:

a) Welding

Low idle with Ranger 300 DLX in the “WELDING TERMINALS ALWAYS ON” mode o with a Ranger 300D - When the electrode touches work, the welding arc is initiated and the engine to accelerates to full speed.

Low idle and in the “WELDING TERMINALS REMOTELY CONTROLLED” mode - Pressing the gun trigger or Amptrol closes the Ranger 300 DLX output contactor and causes the engine to accelerate to full speed.

After the gun trigger or Amptrol is released and/or welding ceases (and no auxiliary power is being drawn), the engine will return to low idle after approximately 10 to 14 seconds.

b)Auxiliary Power - With the engine running at low idle and auxiliary power for lights or tools is drawn (approximately 100-150 watts or greater) from the receptacles, the engine will accelerate to high speed. If no power is being drawn from the receptacles (and not welding) for 10-14 seconds.

3.START PUSH-BUTTON: When the push- button is held, the starter motor cranks over

the engine - release the Button once the engine starts.

NOTE: If you press the START push-button when the engine is running, you may damage the ring gear or starter motor.

4.ENGINE HOUR METER: Records engine running time. Use to determine when to perform required maintenance.

5.BATTERY LIGHT: Is off when battery charging system is functioning normally. If the red light turns on while the engine is running, the fan belt may be broken or the alternator or the voltage reg- ulator may be defective.

It is normal for the light to go on when the “Engine” switch is switched to the “ON” position with the engine not running. It will go off after one minute to prevent discharging the battery if the engine is not started. If this happens, the engine protection circuit must be reset by turning the “Engine” switch to the “OFF” position and back to the “ON” posi- tion.

6.OIL PRESSURE LIGHT: Remains off with proper oil pressure. If the red light turns on while the engine is running, the engine pro- tection system will stop the engine.

It is normal for the light to go on when the “Engine” switch is switched to the “ON” position with the engine not running. It will go off after one minute to prevent discharging the battery if the engine is not started. If this happens, the engine protection circuit must be reset by turning the “Engine” switch to the “OFF” position and back to the “ON” posi- tion.
