SPECIFICATION CHART
GLOSSARY
Cut-in Pressure: While the motor is off, air tank pressure
drops as you continue to use your accessory. 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 you turn on your air compres-
sor and it 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".

7-ENG D22235
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
valve remains closed. On the upstroke of the piston, air is
compressed. The intake valves close and compressed
air is forced out through the exhaust valve, through the
outlet tube, 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: The pressure release valve
located on the side of the pressure switch, is designed to
automatically release compressed air from the compres-
sor head and the outlet tube when the air compressor
reaches "cut-out" pressure or is shut off. If the air is not
released, the motor will try to start but will be unable to.
The pressure release valve allows the motor to restart
freely. When the motor stops running, air will be heard
escaping from the valve for a few seconds. No air should
be heard leaking when the motor is running.
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.
Safety Valve: If the pressure switch does not shut off the
air compressor at its cut-out pressure setting, the safety
valve will protect against high pressure by "popping off"
at its pre-set pressure.
Regulator: The air pressure coming from the air tank is
controlledbytheregulatorknob.Turntheknobclockwise
to increase pressure and counterclockwise 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 pressure
may have to be adjusted while operating the accessory.
Outlet Pressure Gauge: The outlet pressure gauge
indicatestheairpressure available at the outlet side of the
regulator. This pressure is controlled by the regulator and
is always less or equal to the tank pressure. See "Oper-
ating Procedures."
Tank Pressure Gauge: The tank pressure gauge indi-
cates the reserve air pressure in the tank.
You have purchased an air compressor unit consisting of a 1 cylinder, single-stage air compressor pump, an air tank
and associated controls.
This air compressor requires no oil. Now you can enjoy all the benefits of having an air compressor without ever having
to purchase, add or change oil.

D22235
Break-In Procedures
This procedure is only required the first time the air
compressor is put into service.
1. Set the pressure switch OFF/AUTO lever to the "OFF"
position.
2. Plug the power cord into the correct branch circuit
receptacle.
3. Turn the regulator clockwise, opening it fully, to
prevent air pressure build-up in the tank.
4. Move the OFF/AUTO lever to "AUTO". The compres-
sor will start.
5. Run the compressor for 15 minutes. Make sure the
regulator is open and there is no tank pressure build-
up.
6. After 15 minutes, close the regulator by turning it
counterclockwise. The air tank will fill to cut-out
pressure and then the motor will stop.
Refer to Operating Procedures.
RISK OF ELECTRICAL SHOCK. IF REPAIR-
ING OR REPLACING CORD OR PLUG, THE
GROUNDING WIRE MUST BE KEPT SEPA-
RATE FROM THE CURRENT-CARRYING
WIRES. NEVER CONNECT THE GROUNDING
WIRE TO A FLAT BLADE PLUG TERMINAL.
(THE GROUNDING WIRE HAS INSULATION
WITH AN OUTER SURFACE THAT IS GREEN
- WITH OR WITHOUT YELLOW STRIPES.)
If these grounding instructions are not completely under-
stood, or if in doubt as to whether the compressor is
properly grounded, have the installation checked by a
qualified electrician.
Location of the Air Compressor
Locate the air compressor in a clean, dry and well venti-
lated area. The air filter must be kept clear of obstructions
which could reduce air delivery of the air compressor. The
air compressor should be located at least 12" away from
the wall or other obstructions that will interfere with the
flow of air. The air compressor head and shroud are
designedtoallowforpropercooling.Ifhumidity is high, an
air filter can be installed to remove excessive moisture.
Follow the instructions packaged with the air filter for
proper installation.
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 grounding
plug and a 3-slot receptacle that will accept the plug
on the product.
• in good condition.
• no longer than 50 feet.
• 12 gauge (AWG) or larger. (Wire size increases as
gauge number decreases. 10 AWG and 8 AWG may
also be used. DO NOT USE 14 or 16 AWG.)
Grounding Instructions
IMPROPER GROUNDING CAN RESULT IN
ELECTRICAL SHOCK. IN THE EVENT OF A
SHORT CIRCUIT, GROUNDING REDUCES
THE RISK OF SHOCK BY PROVIDING AN
ESCAPE WIRE FOR THE ELECTRIC CUR-
RENT. THIS AIR COMPRESSOR MUST BE
PROPERLY GROUNDED.
1. The air compressor is equipped with a cord having a
grounding wire with an appropriate grounding plug.
The plug must be used with an outlet that has been
installed and grounded in accordance with all local
codes and ordinances. The outlet must have the
same configuration as the plug. DO NOT USE AN
ADAPTER.
2. Do not modify the plug that has been provided. If it
does not fit the available outlet, the correct outlet
should be installed by a qualified electrician.
3. Inspect the plug and cord before each use. Do not
use if there are signs of damage.
INSTALLATION & BREAK-IN PROCEDURES

9-ENG D22235
Before you store the air compressor, make sure you do
the following:
1. Review the "Maintenance" section on the preceding
pages and perform maintenance as necessary. Be
sure to drain water form the air tank.
2. Protect the electrical cord and air hose from damage
(such as being stepped on or run over). Wind them
loosely around the compressor handle and shroud.

AND BLEED OFF ALL AIR PRESSURE.
Air Filter - Inspection
NOTE
Keep the air filter clean at all times. Do not
operate the compressor with the air filter re-
moved.
A dirty air filter will not allow the compressor to operate at
full capacity. Before you use the compressor, check the
air filter to be sure it is clean.
To remove and clean (wash in mild detergent) or replace
the foam air filter, compress the rear slotted end of each
of the two pins holding filter in place and pull pin forward
releasing the filter itself. To reinstall a clean filter, place in
position and push retaining pins into holes securing filter.
NOTE: Wire support screen supplied in the replacement
parts kit, to be positioned behind the foam filter, is not
required on this 3/4 HP model.
Check Valve - Replacement
1. Release all air pressure from air tank and unplug
outfit.
2. Remove shroud.
3. Loosen the top and bottom nuts and remove the
outlet tube.
4. Remove the pressure release tube and fitting.
5. Unscrew the check valve (turn counterclockwise)
using a socket wrench.
6. Check that the valve disc moves freely inside the
check valve and that the spring holds the disc in the
upper, closed position. The check valve may be
cleaned with a solvent, such as paint and varnish
remover.
7. Apply sealant to the check valve threads. Reinstall
the check valve (turn clockwise).
8. Replace the pressure release tube and fitting.
9. Replace the outlet tube and tighten top and bottom
nuts.
10. Replace the shroud.
Safety Valve - Inspection
IF THE SAFETY VALVE DOES NOT WORK
PROPERLY, OVER-PRESSURIZATION MAY
OCCUR, CAUSING AIR TANK RUPTURE OR
AN EXPLOSION. OCCASIONALLY PULL THE
RINGONTHESAFETYVALVETOMAKESURE
THAT THE SAFETY VALVE OPERATES
FREELY. IF THE VALVE IS STUCK OR DOES
NOT OPERATE SMOOTHLY, IT MUST BE RE-
PLACED WITH THE SAME TYPE OF VALVE.
Motor
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 re-start after the motor
cools.
If the overload protector shuts the motor off frequently,
check for a possible voltage problem. Low voltage can
also be suspected when:
1. the motor does not get up to full power or speed;
2. fuses blow out when starting the motor; lights dim
and remain dim when motor is started and is running.
