such as wood, paint, metal,
concrete, cement, or other masonry.
This dust often contains chemicals
known to cause cancer, birth defects,
or other reproductive harm. Wear
protective gear.
GENERAL SAFETY
Since the air compressor and other
components (material pump, spray
guns, filters, lubricators, hoses,
etc.) used, make up a high pressure
pumping system, the following safety
precautions must be observed at all
times:
1. Read all manuals
included with this
product carefully. Be
thoroughly familiar with
the controls and the proper use of
the equipment.
2. Follow all local electrical and safety
codes as well as in the United
States, the National Electrical Codes
(NEC) and Occupational Safety and
Health Act (OSHA).
3. Only persons well acquainted
with these rules of safe operation
should be allowed to use the

6. Do not stand on or use the unit as
a handhold.
7. Before each use, inspect
compressed air system and
electrical components for signs of
damage, deterioration, weakness
or leakage. Repair or replace
defective items before using.
8. Check all fasteners at frequent
intervals for proper tightness.
Motors,
electrical
equipment and controls can
cause electrical arcs that
will ignite a flammable gas
or vapor. Never operate or repair in or
near a flammable gas or vapor. Never
store flammable liquids or gases in the
vicinity of the compressor.
Compressor parts may
be hot even if the unit is
stopped.
9. Keep fingers away from a
running compressor; fast moving
and hot parts will cause injury and/
or burns.
10. If the equipment should start
to vibrate abnormally, STOP
the engine/motor and check
immediately for the cause.
Vibration is generally a warning of
trouble.
11. To reduce fire hazard, keep engine/
motor exterior free of oil, solvent,
or excessive grease.
An ASME code
safety relief valve
with a setting no higher than 170 psi
MUST be installed in the tank for this
compressor. The ASME safety valve
must have sufficient flow and pressure
ratings to protect the pressurized
components from bursting.
See compressor
specification decal
for maximum operating pressure.
Do not operate with pressure switch
or pilot valves set higher than the
maximum operating pressure.
12. Never attempt to adjust ASME
safety valve. Keep safety valve
free from paint and other
accumulations.
Never use plastic
(PVC) pipe for
compressed air. Serious injury or death
could result.
Never
attempt
to repair or modify a tank!
Welding, drilling or any
other modification will
weaken the tank resulting in damage
from rupture or explosion. Always
replace worn, cracked or damaged
tanks.
Drain liquid from
tank daily.
13. Tanks rust from moisture build-up,
which weakens the tank. Make
sure to drain tank regularly and
inspect periodically for unsafe
conditions such as rust formation
and corrosion.
14. Fast moving air will stir up dust
and debris which may be harmful.
Release air slowly when draining
moisture or depressurizing the
compressor system.
SPRAYING PRECAUTIONS
Do not
spray
flammable materials in
vicinity of open flame
or near ignition sources
including the compressor unit.
15. Do not smoke when spraying paint,
insecticides, or other flammable
substances.
16. Use a face mask /
respirator when spraying
and spray in a well
ventilated area to
prevent health and fire
hazards.
17. Do not direct paint or other
sprayed material at the compressor.
Locate compressor as far away
from the spraying area as
possible to minimize overspray
accumulation on the compressor.
18. When spraying or cleaning with
solvents or toxic chemicals, follow
the instructions provided by the
chemical manufacturer.
Introduction
Refer to Figure 2 to locate the
following items.
On/Off Switch — This unit is
equipped with an illuminated
On / Off switch. In the “ON” position
the button will be depressed and
the switch will light up. The switch
will remain lit as long as the button
is depressed and there is power to
the unit. The pressure switch will
automatically turn the pump / motor
on or off based on the pressure inside
the tank. If the unit is unplugged the
light will not be on. In the “OFF
position the switch will not be
depressed and the light will not be on.

Operating Instructions and Parts List
Introduction (Continued)
Pressure Switch (located
internally) - When the compressor
is turned ON, this switch will shut
compressor off automatically when
tank pressure reaches maximum shut-
off / cut-out pressure. If compressor
remains on and air is depleted from
tank, this switch will allow compressor
to automatically restart at the restart /
cut-in pressure.
Regulator - The regulator controls
the amount of air pressure released at
the hose outlet. Turning the regulator
knob clockwise (to the right) will
increase air pressure at the outlet.
Turning the knob counter-clockwise
(to the left) will lower air pressure to
the outlet. Turning knob fully counter-
clockwise will shut off flow of air
completely.
Pressure Gauges - There are two
gauges on this compressor. These
gauges read air pressure in pounds
per square inch (psi). The larger
gauge shows pressure at the outlet.
Make sure this gauge reads ZERO
(by adjusting the regulator) BEFORE
changing air tools or disconnecting
hose from outlet. The small gauge
shows pressure in the tank indicating
compressor is building pressure
properly.
Installation
LOCATION
It is extremely important to use the
compressor in a clean, well ventilated
area where the surrounding air
temperature will not be more than
104°F.
A minimum clearance of 18 inches
between the compressor and a wall
is required because objects could
obstruct air flow.
Do not locate the
compressor
air inlet near steam, paint spray,
sandblast areas or any other source
of contamination. This debris will
damage the motor.
GROUNDING INSTRUCTIONS
1. This product is for use on a
nominal 120 volt circuit and has a
grounding plug that looks like the
plug illustrated in Figure 3. Make
sure the product is connected
to an outlet having the same
configuration as the plug. This
product must be grounded. In
the event of an electrical short
circuit, grounding reduces risk of
electrical shock by providing an
escape wire for electric current.
This product is equipped with a
cord having a grounding wire
with an appropriate grounding
plug. Plug must be plugged into
an outlet that is properly installed
and grounded in accordance with
all local codes and ordinances.
ASME Safety Valve - This valve
automatically releases air if the tank
pressure exceeds the preset maximum.
Handle - Designed to move the
compressor.
Drain Valve - This valve is located on
the bottom of the tank. Use this valve
to drain moisture from the tank daily
to reduce the risk of corrosion.
Motor Reset - (not shown, located
inside motor). If the unit is over
worked, a motor reset (also known as
an overload protector) will shut the
unit off.
This compressor is
equipped with an
overload protector which will shut off
motor if it becomes overloaded.
If the unit shuts off, place ON / OFF
switch in the OFF position and wait
approximately 30 minutes for unit to
cool down. Turn switch to ON position
again to resume work.
If the overload
protector is
actuated, the motor must be allowed
to cool down for approximately 30
minutes before it will reset.

Installation (Continued)
Improper
use of
grounding plug can result in
a possible risk of electrical
shock!
Do not use a
grounding adapter
with this product!
2. If repair or replacement of cord or
plug is necessary, do not connect
grounding wire to either flat blade
terminal. The wire with insulation
having an external surface that
is green (with or without yellow
stripes) is the grounding wire.
Never connect
green (or green
and yellow) wire to a live terminal.
3. Check with a qualified electrician
or serviceman if grounding
instructions are not completely
understood, or if in doubt as
to whether product is properly
grounded. Do not modify plug
provided; if it will not fit outlet,
have proper outlet installed by a
qualified electrician.
Overheating, short
circuiting and fire
damage will result from inadequate
wiring.
LUBRICATION
This is an oilless product and DOES
NOT require lubrication to operate.
Pre-Operation
BEFORE FIRST START-UP
BREAK-IN PROCEDURE
(Complete this procedure before
using compressor for the first time.
Once completed, it is not necessary to
repeat.)
1. Turn regulator knob fully clockwise
(to the right) to open air flow.
2. Do not attach a hose or any other
fitting to the compressor.
3. Turn ON / OFF switch to OFF
position.
4. Plug in power cord.
5. Turn ON / OFF switch to ON
position and run compressor for 30
minutes.
6. Turn ON / OFF switch to OFF
position.
7. Unplug power cord.
The compressor is now ready for use.
BEFORE EACH START-UP
OPERATING PROCEDURE
1. Turn regulator knob fully
counterclockwise (to the left) to
close air flow.
2. Connect air hose to outlet of
regulator.
3. Turn ON / OFF switch to OFF
position.
4. Plug in power cord.
5. Turn ON / OFF switch to ON
position and let compressor run
until it reaches automatic shutoff
pressure.
6. Attach tire chuck or tool to end of
hose.
7. Turn regulator knob clockwise (to
the right) to desired pressure of
tool being used.
Operation
START-UP
Do not attach air
tools to open end
of the hose until start-up is completed
and the unit checks OK.
ON / OFF CYCLING OF COMPRESSOR
In the ON / AUTO position, the
compressor pumps air into the tank.
When a shut-off (preset “cut-out”)
pressure is reached, the compressor
automatically shuts off.
If the compressor is left in the
ON / AUTO position and air is depleted
from the tank by use of a tire chuck,
tool, etc., the compressor will restart
automatically at its preset “cut-in”
pressure. When a tool is being used
continuously, the compressor will cycle
on and off automatically.
In the OFF position, the pressure
switch cannot function and the
compressor will not operate. Make
sure switch is in OFF position when
connecting or disconnecting power
cord from electrical outlet.
PRESSURE GAUGES
The large gauge next to the regulator
knob indicates air pressure going to
hose (and any tool attached to end of
hose).
The small gauge next to the safety
valve indicates air pressure in tank.
MOISTURE IN COMPRESSED AIR
Moisture in compressed air will form into droplets as it comes from an
air compressor pump. When humidity is high or when a compressor is in
continuous use for an extended period of time, this moisture will collect
in the tank. When using a paint spray or sandblast gun, this water will be
carried from the tank through the hose, and out of the gun as droplets mixed
with the spray material.
IMPORTANT: This condensation will cause water spots in a paint job,
especially when spraying other than water based paints. If sandblasting, it
will cause the sand to cake and clog the gun, rendering it ineffective.
A filter in the air line, located as near to the gun as possible, will help
eliminate this moisture.
