3. Move the GEN/WELD switch to the
GEN position.
NOTE: Failure to allow the engine to cool
at idle for two (2) minutes may result in
damage to the generator.
4. Drain air from the air tanks by
releasing air with an attached air
tool or by pulling on the Safety
Relief Valve.
5. Once the Air Tank Pressure Gauge
registers under 10 pounds, open
the drain valve under each air tank
to drain any moisture.
6. Close fuel valve on unit or engine.
7. Allow the unit to cool down.
8. Wipe the unit clean and store in a
safe, non-freezing, dry area.
OPERATING CONTROLS
Idle Control Operation:
Note: Idle control is disabled in welding
mode. Idle control switch must be at full
throttle setting.
The idle control is factory installed.
This electrical device is designed to let
the engine run at fuel saving low idle
speed when the generator or compres-
sor are not loaded, and at full normal
governed speed when a load is applied.
The idle system overrides the engine
governor to provide idle speed. When
a load is applied, the electronic circuit
reacts to de-energize the idle system
so that the engine can resume full gov-
erned operating speed.
The idle control system controls the
engine speed in the following manner:
1. With the idle control switch in the
“FULL THROTTLE” position, start
the engine.
2. After one or two minute warm up
period, apply load and move the
switch to the “IDLE CONTROL”
position. The engine will throttle
back to idle speed following a 5-8
second delay.
3. When a load is applied to the
generator or air compressor tank
pressure drops below regulated
set point, the idle control system
becomes de-energized. The engine
then accelerates to normal op-
erating speed, controlled by the
governor.
4. When the load is removed or
air compressor tank pressure is
restored, the idle system becomes
re-energized and throttles the en-
gine back to idle speed after a 5-8
second delay.
NOTE: While the engine is idling, the
generator voltage is automatically
reduced to reduce generator
temperatures. The voltage will return
to normal levels immediately upon the
application of load.
MAINTENANCE
Cable Size:
Equipment damage can result from low
voltage. Therefore, to prevent excessive
voltage drop between the unit and the
equipment, the cable should be of ad-
equate gauge for the length used. The
cable selection chart gives the maxi-
mum cable lengths for various gauges
of wire which can adequately carry the
loads shown.
Electric Motor Loads:
It is characteristic of common electric
motors in normal operation to draw up
to six times their running current while
starting. This table may be used to esti-
mate the watts required to start “CODE
G” electric motors.
If an electric motor fails to start or
reach running speed, turn off the
appliance or tool immediately to
