CAUTION
!
Exercise extreme caution when using
a booster battery to start. To jump
start: Connect the ends of one booster
cable to the positive (+) terminals of
each battery. Then connect one end of
the other cable to the negative (-)
terminal of the booster battery and the
other end to the engine block. NOT TO
THE NEGATIVE (-) TERMINAL OF THE
WEAK BATTERY.
After Starting:
a. Reduce engine speed to IDLE.
b. Disconnect the negative (-) cable from
the engine block first, then from the
booster battery.
c. Disconnect positive (+) cable from both
batteries.
CAUTION
!
Do not remove pressure cap from a
HOT radiator. Allow radiator to cool
down before removing pressure cap.
Use extreme care when removing a
pressure cap from a liquid cooling
system for the engine. The sudden
release of pressure from a heated
cooling system can result in a loss of
coolant and possible severe personal
injury.
Operation Of Optional Generator
This unit will operate in three modes,
depending on the position of the generator
control switch (located on the front of the
generator control panel).
• In “Generator” position, the engine
will maintain idle speed, and the
generator will give a constant voltage
and frequency output, for use with
sensitive equipment like computers,
fusion welders, etc. No compressed
air is available at the service air
valves in this mode.
• In “Gen/Air” position, voltage and
frequency will vary as engine speed
changes to meet air demands, and
should only be used for lights and hand
tools.
• In “Air” position, the generator provides
no electrical power.
1. Start compressor with the Start-Run
Switch located in the bottom right corner
of the instrument panel) in the “Start/
Warm-up” position.
2. Close all service air valves.
3. Place the start-run switch in the “Run”
position.
4. Place the generator control switch in
either “Generator” or “Gen/Air” position.
The red light on the front of the generator
control panel should glow, and the
voltage meter should read 120 Volts AC.
5. Plug electric tools or lights into the
receptacles on the front of the generator
control panel.
Units With Diagnostic Lamps:
In a shutdown situation, the function of the
panel lamps is to indicate what specific
failure caused the unit to shut down.These
lamps will remain illuminated until the Power
Switch is turned “OFF”.
