4.ENGINE TEMPERATURE GAUGE AND LIGHT: The gauge displays the engine oil temperature. The yellow temperature light remains off under normal operating temperatures. If the light turns on, the engine protection system will shut down the engine. Check for restrictions at the engine cooling air inlets and outlets (consult the engine Operation manual). Check for loose or disconnected leads at the tem- perature sender located on the engine. Check engine cooling blower belt. Also, check to be sure that the welder loads are within the rating of the welder. The light will remain on when the engine has been shut down due to an over- temperature condition.

5.OIL PRESSURE GAUGE AND LIGHT: The gauge displays the engine oil pressure when the engine is running. The yellow oil pressure light remains off with proper oil pressure. If the light turns on, the engine protection system will stop the engine. Check for proper oil level and add oil if necessary. Check for loose or disconnected leads at the oil pressure sender located on the engine. The light will go on and stay on when the RUN-STOP switch is switched to the “RUN” position with the engine not running.

6.ENGINE ALTERNATOR AMMETER AND LIGHT: The yellow engine alternator light is off when the battery charging system is functioning normally. If the light turns on, the engine protection system will shut down the engine. Check the engine cooling blower belt. Also, the alternator or the voltage reg- ulator may not be operating correctly. The light may also come on if the alternator did not flash up due to not holding the start button in long enough (mini- mum of 2 seconds) or due to a faulty flashing circuit. The light will remain on when the engine has been shut down due to a fault in the alternator, regulator, or the cooling blower belt.

7.IDLER SWITCH: Adjusts the running speed of the engine. Has two positions as follows:

A)In the “High” position, the engine runs at the high idle speed controlled by the governor.

B)In the “Auto” position, the idler operates as follows:

a.When switched from “HIGH” to “AUTO” or after starting the engine, the engine will operate at full speed for approximately 15 seconds and then go to low idle speed.

b. When the electrode touches the work or power is drawn for lights or tools (approxi- mately 100 Watts minimum), the engine accelerates and operates at full speed.

c. When welding ceases or the AC power load is turned off, a fixed time delay of approxi- mately 15 seconds starts.

d. 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.

e. The engine will automatically return to high idle speed when the welding load or AC power load is reapplied.

Idler Operational Exceptions

When the WELDING TERMINALS switch is in the

“WELDING TERMINALS REMOTELY CONTROLLED” position, the idler will operate as follows:

a. When the triggering device (Amptrol, Arc Start Switch, etc.) is pressed, the engine will accelerate and operate at full speed provided a welding load is applied within approximately 15 seconds.

If the triggering device remains pressed but no welding load is applied, within approximately 15 seconds the engine will return to low idle speed.

If the triggering device is released or welding ceases, the engine will return to low idle speed after approximately 15 seconds.

8.HOUR METER: The hour meter displays the total time that the engine has been running. This meter is a useful indicator for scheduling preventive main- tenance.
