DESCRIPTION
OF OPERATION
Air Compressor
Pump:
To compress air, the piston
moves up and down in the cylinder. On the downstroke,
air is drawn in through the air intake valves. The exhaust
valves remain closed. On the upstroke of the piston, air
is compressed. The intake valves close and compressed
air is forced out through the exhaust valves, through the
outlet tubes, through the check valve and into the air tank.
Working air is not available
until the compressor has
raised the air tank pressure above that required at the air
outlet.
Check Valve:
When the air compressor is operating, the
check valve is "open", allowing compressed air to enter
the air tank. When the air compressor reaches "cut-out"
pressure, the check valve "closes", allowing air pressure
to remain inside the air tank.
Pressure Release Valve:
This unit DOES NOT require
a pressure release valve.
Pressure
Switch:
The pressure switch automatically
starts the motor when the air tank pressure drops below
the factory set "cut-in" pressure.
It stops the motor when
the air tank pressure reaches the factory set "cut-out"
pressure.
Motor Thermal
Overload
Protector:
The electdc
motor has an automatic thermal ovedoad protector. If the
motor overheats
for any reason, the thermal overload
protector will shut off the motor. The motor must be
allowed to cool before restarting.
Regulator:
The air pressure coming from the air tank is
controlled
by the regulator.
Turn the regulator
knob
clockwise to increase pressure and counter-clockwise
to
decrease pressure.
To avoid minor readjustment after
making a change in pressure setting, always approach
the desired
pressure from a lower pressure.
When
reducing from a higher to a lower setting, first reduce to
some pressure less than that desired, then bring up to the
desired pressure. Depending on the air requirements of
each particular accessory, the outlet regulated air pres-
sure may have to be adjusted while operating the acces-
sory.
OutJet Pressure
Gauge:
The outlet pressure gauge
indicatesthe air pressure available at the outlet side of the
regulator. This pressure is controlled bythe regulator and
is always
less or equal to the tank pressure.
See
"Operating Procedures".
Tank
Pressure
Gauge:
The tank pressure gauge
indicates the reserve air pressure in the tank.
Cooling
System:
This compressor
contains
an ad-
vanced design cooling system. At the heart of this cooling
system is an engineered fan. It is perfectly normal for this
fan to blow air through the vent holes in large amounts.
You know that the cooling system is working when air is
being expelled.
Air Intake
Filter:
The advance design of this unit
requires no air filter.
Drain Valve:
The drain valve is located at the base of
the air tank and is used to drain condensation at the end
of each use.
On/Auto-Off
Switch:
Turn this switch ON to provide
automatic
power to the pressure switch and OFF to
remove power at the end of each use.
INSTALLATION
AND
BREAK-IN
PROCEDURES
Location
of the
Air
Compressor
Your compressor comes to you completely
assembled
and ready for use. Operate the air compressor in a dry,
clean, cool and well ventilated area. The air compressor
pump and case are designed to allow for proper cooling.
Clean or blow off dust or dirt that collects on the air
compressor.
A clean air compressor
runs cooler and
provides longer service.
The ventilation
openings on
your air compressor
are necessary to maintain proper
operating
temperature.
Do not place rags or other
containers on or near these openings.
Voltage
and
Circuit
Protection
See front cover.
Extension
Cords
Use extra air hose instead of an extension cord to
avoid voltage drop and power loss to the motor.
If an extension cord must be used, be sure it is:
a 3-wire extension cord that has a 3-blade ground-
ing plug, and a 3-slot receptacle that will accept
the plug on the compressor
in good condition
no longer than 50 feet
14 gauge (AWG) or larger. (VVire size increases
asgauge number decreases.)
12 AWG, IOAWG
and 8 AWG may also be used. DO NOT USE 16
OR 18 AWG.
