B-3 OPERATION B-3
6. OIL PRESSURE GAUGE
The gauge displays the engine oil pressure when
the engine is running.
7. ENGINE PROTECTION
The yellow engine protection light remains off with
proper oil pressure and under normal operating tem-
peratures. 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 locat-
ed on the engine. The light will remain on when the
engine has been shut down due to low oil pressure
or over-temperature condition.
8. BATTERY CHARGING 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 operating correctly. The light may also come on
due to a faulty flashing circuit. The light will remain
on when the engine is stopped and the run/stop
switch is in the run position.
9. 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
operates 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 and the AC power load
is turned off, a fixed time delay of approximate-
ly 12 seconds starts.
d. If the welding or AC power load is not restart-
ed 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
“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 may 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.
