air pressure signal to the pressure switch, which
activates the throttle solenoid.
When the air tank pressure builds to 175 psi, a spring
loaded valve in the pilot valve opens, providing an air
pressure signal to the head unloader valves of the
compressor. This causes the air in the compressor to
vent to the atmosphere. This air signal is also sent to the
throttle pressure switch, energizing the throttle solenoid.
When the air tank pressure falls below 150 psi, the pilot
valve will close, stopping the air signal to the unload
valves, allowing the compressor to start pumping air to
the tank. This signal also causes the pressure switch to
de-energize the throttle solenoid, forcing the engine to
full speed.
A lever on the top of the pilot valve will allow the operator
to manually stop the compression of air by the
compressor during initial engine start-up or if operation
does not require the use of compressed air (
Figure 5-5 ).
Since the head unloader valves require air pressure to
operate, there must be a minimum of 10 psi in the air tank
to allow the valves to operate properly.
For additional information on manually controlling the
pilot valve function, consult
Section 2.2.4, Pilot Valve ,
and Section A.8, Pressure System Control - Function
Sequences .
When purchasing air tools or planning a project, the rated
capacity of the compressor (24 CFM up to 175 psi) will
need to be taken into consideration. See
Appendix A,
Section A.4, Air Tool Air Consumption Chart , for
information on the compressed air requirements of
common tools. If the equipment is not listed in
Section
A.4 , check the desired power tool manufacturer’s
specifications. An air storage tank (30 gallon available)
can allow additional air CFM output for intermittent use.
NOTE
The leading cause of component failure
of the air control system is moisture. Air
tanks must be drained daily as a
minimum to eliminate condensation.
NOTE
The pressurized air system requires
routine maintenance. See Section 6.3,
Maintenance Schedule Table , for
important maintenance procedures.

NOTE
The Air N Arc 200 Power System unit
features a high pressure, 175 psi air
system. Check the maximum air
pressure rating on the air tools being
used. The operator is responsible for
regulating the air pressure when
necessary (See Section 6.5.5, Adjusting
Compressor Cut-In/Cut-Out Pressure ).
NOTE
The pressurized air system requires
routine maintenance. See Section 6.3,
Maintenance Schedule Table , for
important maintenance procedures.
CAUTION
Exposed high pressure air lines on the
unit become hot during operation— keep
everyone clear.
