GASOLINE ENGINE CONTROLS
(CLASSIC III)
See Figure B.3 for the location of the following features:
1. IDLER CONTROL TOGGLE SWITCH: Adjusts the
running speed of the engine. The switch has two
positions, "HIGH" and "AUTO." In "HIGH," the
engine runs continuously at high idle. In "AUTO,"
the idler control works as follows:
Welding: The engine accelerates to high speed
when the electrode touches the work and strikes a
welding arc. The engine returns to low idle approx-
imately 15 seconds after welding stops, as long as
no auxiliary power is being drawn.
Auxiliary Power: The engine accelerates to high
speed when power is drawn at the receptacles for
lights or tools. The engine returns to low idle
approximately 15 seconds after demand for
auxiliary power stops.
2. IGNITION CONTROL TOGGLE SWITCH: Has
two positions, ON and OFF. When the switch is in
the ON position, the engine can be started by
pressing the START pushbutton. When the switch
is placed in the OFF position, the engine stops.
3. CHOKE: Provides a richer air/fuel mixture for cold
engine starting conditions. See the topic
Engine
Operation
for details on setting the choke.
4. START PUSHBUTTON: Press the START button
to start the engine. The IGNITION switch must be
in the ON position.
NOTE: If you press the START pushbutton when
the engine is running, you may damage the engine
flywheel gear or starter motor.
5. ENGINE HOUR METER: Records engine running
time. Use the meter to determine when to
perform required maintenance.
6. AMMETER: Shows whether the charging circuit
is performing its job of charging the battery when
the engine is running. The meter will register
discharge during starting, but then the needle
should return to a position slightly toward positive
during running. The needle will hold position in the
center when the engine stops.
