4.ENGINE TEMPERATURE GAUGE (K1639-2 Std., K1639-1 Opt.) 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 Operator’s Manual). Check for loose or disconnected leads at the temperature 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 (K1639-2 Std., K1639-1 Opt.) 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 engine not running.

6.ENGINE ALTERNATOR AMMETER (K1639- 2 Std., K1639-1 Opt.) AND LIGHT

The yellow engine alternator light is off when battery charging system is functioning normally. If light turns on, the engine protection system will shut down the engine. Check the engine cooling blower belt. Also, the alternator or the voltage regulator may not be operat- ing correctly. The light may also come on due to a faulty flashing circuit. The light will remain on when the engine has been shut down due to a fault in the alter- nator, regulator, or the cooling blower belt.

7. IDLER SWITCH

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 oper- ates as follows:

a.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.

b.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.

c. When welding ceases or the AC power load is turned off, a fixed time delay of approximately 12 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 A.C. 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 12 seconds.

If the triggering device remains pressed but no weld- ing load is applied within approximately 12 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 approxi- mately 12 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 maintenance.
