ON/AUTO/OFF SWITCH
Place this switch (L) in the ON/AUTO
H
L
position to provide automatic power to the
pressure switch and OFF to remove power
at the end of each use. NOTE: ALWAYS
ensure the switch (L) is in the OFF
position before removing or replacing
pressure switch cover.
PRESSURE SWITCH
The pressure switch (H) 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.
SAFETY VALVE
If the pressure switch does not shut off the air
G
compressor at its cut-out pressure setting, the
safety valve (G) will protect against high pressure
by popping out at its factory set pressure (slightly
higher than the pressure switch cut-out setting).
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.
TANK PRESSURE GAUGE
The tank pressure gauge (K) indi-
E
F
D
K
cates the reserve air pressure in
the tank.
REGULATED PRESSURE
GAUGE
The regulated pressure gauge (D)
indicates the air pressure available
at the outlet side of the regulator. This pressure is controlled by the
regulator and is always less than or equal to the tank pressure.
REGULATOR
The regulator (F) controls the air pressure shown on the regulated
pressure gauge. Pull the knob out and turn clockwise to increase
pressure and counterclockwise to decrease pressure. When the
desired pressure is reached push knob in to lock in place.
UNIVERSAL QUICK CONNECT BODIES
The universal quick connect body (E) accepts the three most popular
styles of quick connect plugs: Industrial, automotive, and ARO. One
hand push-to-connect operation makes connections simple and
easy. The two quick connect bodies allow the use of two tools at the
same time.
DRAIN VALVE
The drain valve (B) is located at the base of
B
the air tank and is used to drain
condensation at the end of each use.
See
Draining Air Tank under Maintenance.
COOLING SYSTEM
This compressor contains an advanced design cooling system.
It is normal for this fan to blow air through the vent holes in large
amounts. The cooling system is working when air is expelled.
10

AIR COMPRESSOR PUMP
The pump compresses air 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.
AIR INTAKE FILTER
The filter (J) is designed to clean air entering the
J
pump. To ensure the pump continually receives a
clean, cool, and dry air supply the filter must always
be clean and the filter intake must be free from
obstructions.
MOTOR OVERLOAD PROTECTOR
The motor has an automatic reset thermal overload protector. If the
motor overheats for any reason, the overload protector will shut off
the motor. The motor must be allowed to cool down before restarting.
The compressor will automatically restart after the motor cools.

1. Ensure On/Auto/Off switch is in the OFF position.
2. Remove air compressor plug from outlet.
3. Drain air tank.
4. Allow air compressor to cool down before starting service.
NOTE: All compressed air systems contain maintenance parts (e.g.,
oil, filters, separators) that are periodically replaced. These used parts
may contain substances that are regulated and must be disposed of in
accordance with local, state, and federal laws and regulations.
NOTE: Take note of the positions and locations of parts during
disassembly to make reassembly easier.

WARNING: Risk of bursting. If the safety valve does not work
properly, over-pressurization may occur, causing air tank rupture or
an explosion.
WARNING: Risk from flying objects. Always wear certified safety
equipment: ANSI Z87.1 eye protection (CAN/CSA Z94.3) with side
shields when using the compressor.
Before starting compressor, pull the ring on the safety valve to
make sure that the safety valve operates freely. NOTE: Ring may
be difficult to pull when air tank pressure is at 0 PSI. If the valve is
stuck or does not operate smoothly, it must be replaced with the
same type of valve.

WARNING: Risk of unsafe operation. Risk from noise. Air tanks
contain high pressure air. Keep face and other body parts away from
outlet of drain. Use eye protection [ANSI Z87.1 (CAN/CSA Z94.3)]
when draining as debris can be kicked up into face.
WARNING: Risk from noise. Use ear protection [ANSI S12.6
(S3.19)] as air flow noise is loud when draining.
NOTE: All compressed air systems generate condensate that
accumulates in any drain point (e.g. tanks, filter, aftercoolers, dryers).
This condensate contains lubricating oil and/or substances which
may be regulated and must be disposed of in accordance with local,
state, and federal laws and regulations.
1. Ensure On/Auto/Off switch is in the OFF position.
2. Lift compressor into an inclined position so drain valve (B) is at
the lowest point (this will assist in removing moisture, dirt, etc.
from air tanks).
3. Place a suitable container under the drain valve to catch
discharge.
4. Grasp lever on drain valve.
5. Slowly rotate lever to gradually bleed air from air tank.
WARNING: Risk of bursting. Drain air tank daily. Water will con-
dense in air tank. If not drained, water will corrode and weaken the
air tank causing a risk of air tank rupture.
CAUTION: Risk of property damage. Drain water from air tank may
contain oil and rust, which can cause stains.
6. When air tank pressure gauge reads 10 PSI, rotate valve to the
fully open position.
7. Close drain valve when finished.

CFM: Cubic feet per minute.
SCFM: Standard cubic feet per minute; a unit of measure of air
delivery.
PSI: Pounds per square inch; a unit of measure of pressure.
kPa (kilopascal): Metric pressure measurement. 1 kilopascal
equal 1000 pascals.
Code Certification: Products that bear one or more of the
following marks: UL, CUL, ETL, CETL, have been evaluated by
OSHA certified independent safety laboratories and meet the
applicable Standards for Safety.
Cut-In Pressure: While the motor is off, air tank pressure drops
when accessory is used. When the tank pressure drops to a certain
low level the motor will restart automatically. The low pressure at
which the motor automatically restarts is called cut-in pressure.
Cut-Out Pressure: When an air compressor is turned on and
begins to run, air pressure in the air tank begins to build. It builds
to a certain high pressure before the motor automatically shuts
off, protecting your air tank from pressure higher than its capacity.
The high pressure at which the motor shuts off is called cut-out
pressure.
Branch Circuit: The circuit carrying electricity from electrical panel
to outlet.
Duty Cycle: This air compressor pump is capable of running
continuously. However, to prolong the life of your air compressor,
it is recommended that a 50%-75% average duty cycle be
maintained; that is, the air compressor pump should not run more
than 30-45 minutes in any given hour.
