GASOLINE ENGINE CONTROLS

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 receptacle 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. OIL PRESSURE LIGHT: Lights when the engine

oil pressure drops to an unsafe level. If the light
comes on within 30 seconds after startup, the
engine should be stopped by placing the IGNITION
switch in the OFF position.

4. START PUSHBUTTON: Press this button to start

the gasoline 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.

6. ENGINE HOUR METER: Records engine running

time.

Use the meter to determine when to

perform required maintenance.

7. 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.
