Risk of Explosion or Fire
Risk of Bursting
Risk to Breathing
(Asphxiation)
Air Tank: On February 26,
2002, the U.S. Consumer
Product Safety Commission
published Release # 02-108 concerning
air compressor tank safety:
Air compressor receiver tanks do
not have an infinite life. Tank life
is dependent upon several factors,
some of which include operating
conditions, ambient conditions, proper
installations, field modifications,
and the level of maintenance. The
exact effect of these factors on air
receiver life is difficult to predict.
If proper maintenance procedures are
not followed, internal corrosion to the
inner wall of the air receiver tank can
cause the air tank to unexpectedly
rupture allowing pressurized air
to suddenly and forcefully escape,
posing risk of injury to consumers.
The following conditions could lead
to a weakening of the air tank, and
result in a violent air tank explosion:
• Failure to properly drain condensed
water from air tank, causing rust and
thinning of the steel air tank.
• Drain air tank daily or after each use.
If air tank develops a leak, replace it
immediately with a new air tank or
replace the entire compressor.
• Modifications or attempted repairs to
the air tank.
• Never drill into, weld, or make any
modifications to the air tank or its
attachments. Never attempt to repair a
damaged or leaking air tank. Replace
with a new air tank.

Assembly / Installation
Assembling the Compressor Installation
The air compressor
should be turned
off, unplugged from the power source,
the air bled from the tank and the
unit allowed time to cool before any
maintenance is performed. Personal
injuries could occur from moving parts,
electrical sources, compressed air or hot
surfaces. The quick connect assembly
must be attached before use. Failure to
assemble correctly could result in leaks
and possible injury.
If unsure of assembly instructions or
you experience difficulty in the assembly
please call your local service department
for further information.
1. Unpack the air compressor. Inspect
the unit for damage. If the unit has
been damaged in transit, contact
the carrier and complete a damage
claim. Do this immediately because
there are time limitations to damage
claims.
2. Check the compressor’s serial label
to ensure that you have received the
model ordered, and that it has the
required pressure rating for its
intended use.
3. Locate the compressor according to
the following guidelines:
a. Position the compressor near
a grounded electrical outlet.
b. The compressor must be at
least 12 inches (31 cm) from
any wall or obstruction, in a
clean, well-ventilated area, to
ensure sufficient air flow and
cooling.
c. In cold climates, store portable
compressors in a heated
building when not in use. This
will reduce problems with
motor starting and freezing of
water condensation.
d. Remove the compressor from
the carton and place it on the
floor or a hard, level surface.
The compressor must be level
to ensure proper drainage of
the moisture in the tank.
Location of the Air Compressor
The air compressor should always be

be exposed to flammable liquids or
vapors. This product is not intended
for installation or use in a commercial
garage or shop environment.
Grounding Instructions
This product must be grounded. In
the event of an electrical short circuit,
grounding reduces the risk of electric
shock by providing an escape wire
for the electric current. This product
is equipped with a cord having a
grounding wire with an appropriate
grounding plug. (See Figure 3.) The
plug must be plugged into an outlet
that is properly installed and grounded
in accordance with all local codes and
ordinances. Check with a qualified
electrician or service personnel if
these instructions are not completely
understood or if in doubt as to whether
the tool is properly grounded.
Improper installation of the
grounding plug will result
in a risk of electric shock.
If repair or replacement
of the cord or plug is necessary, do
not connect the grounding wire to
either flat blade terminal. The wire with
insulation having an outer surface that
is green with or without yellow stripes
is the grounding wire. Substitution
of the signal word “DANGER” for
“WARNING” is not prohibited when
the risk associated with the product is
such that a situation exists which if not
avoided will result in death or serious
injury. Check with a qualified electrician
or serviceman if the grounding
instructions are not completely
understood, or if in doubt as to whether
the product is properly grounded. Do
not modify the plug provided; if it will
not fit the outlet, have the proper outlet
installed by a qualified electrician.
This product is for use on a nominal
120-V circuit and has a grounding plug
similar to the plug illustrated in (Figure
3). Only connect the product to an outlet
having the same configuration as the
plug. Do not use an adapter with this
product.
Extension Cords
Use only 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. Make sure your
extension cord is in good condition.
When using an extension cord, be
sure to use one heavy enough to carry
the current your product will draw.
Cords must not exceed 50 feet and
No. 12 AWG size must be used. An
undersized cord will cause a drop in line
voltage resulting in loss of power and
overheating.
Break In Procedures
No break in procedure is required
by the user. This product is factory
tested to ensure proper operation and
performance.

NOTE: To reset the motor overload toggle
turn the Power Switch to the OFF position
and unplug the unit from the power outlet.
Allow 10 minutes (minimum) for motor
overload cut-out to cool and reset. Unit
can then be plugged in and re-started..
Draining the Tank
Condensation
will accumulate in the tank. To prevent
corrosion of the tank from the inside, this
moisture must be drained at the end of
every workday. Be sure to wear protective
eyewear. Relieve the air pressure in the
system and open the drain valve on the
bottom of the tank and tilt tank to drain.
NOTE: In cold climates, drain the tank
after each use to reduce problems with
freezing of water condensation.
Checking the Safety Valve
(Figure 5)
Check the safety valve by performing
these three steps:
1. Plug the compressor in and run
until shut-off pressure is reached.
2. Wearing safety glasses, pull out on
the safety valve ring to release
pressure from the tank.
3. The safety valve should close
automatically at approximately
at 40-50 PSI.
If the safety valve does not allow
air to be released when
you pull out on the ring, or does
not close automatically, it must be
replaced.
Storage
For storing the air compressor, be sure to
do the following:
1. Turn the unit off and unplug the
power cord from the receptacle.
2. Remove all air hoses, accessories,
and air tools from the air compressor.
3. Perform the daily maintenance
schedule.
4. Open the drain valve to bleed all air
from the tank.
5. Close the drain valve.
6. Protect the electrical cord and air hose
from damage (such as being stepped
on or run over). Wind them loosely
around the compressor handle.
7. Store the air compressor in a clean
and dry location.

Troubleshooting
Risk of Unsafe
Operation. Unit cycles automatically when
power is on. When servicing, you may be
exposed to voltage sources, compressed
air, or moving parts. Before servicing unit
PROBLEM CAUSE CORRECTION
Low pressure or
not enough air
or Compressor
does not stop
Tank drain valve is open Close drain valve
Fittings leak Check fittings with soapy water. Tighten or reseal
leaking fittings. DO NOT OVERTIGHTEN.
Restricted air intake Clean or replace intake filter element.
Prolonged excessive use of air Decrease amount of air used.
Compressor not large enough Check air requirement of accessory. If it is higher than CFM and
pressure supplied by compressor, you need a larger compressor.
Most accessories are rated at 25% of actual CFM while running continuously.
Hole in air hose Check and replace if necessary.
Tank leaks
Immediately replace tank. DO NOT attempt to repair.
Blown seals Replace seals.
Valve leaks Replace seals.
Leaking or worn piston Replace piston.
Air leaks from
regulator, or
regulator does not
regulate pressure
Dirty or damaged regulator
internal parts.
Replace regulator or internal parts.
Regulated
pressure
gauge reading
drops when air
accessory is
being used
This is normal If pressure drops too low, adjust regulator while accessory is used.
Compressor not large enough Check air requirement of accessory. If it is higher than CFM and pressure
supplied by compressor, you need a larger compressor. Most accessories
are rated at 25% of actual CFM while running continuously.
Pressure relief
valve opens
Tank pressure exceeded
normal operating pressure
Replace pressure switch
Pressure switch stuck Replace pressure switch
Motor will not run Tank pressure exceeds preset pres-
sure switch limit
Motor will start automatically when tank pressure drops
below cut- in pressure of pressure tank.
Make sure the Thermal Overload
Switch has not tripped. The motor
has a built in thermal cut out that trips
when necessary to protect the motor
from damage when overheated.
Fuse blown or circuit breaker tripped
To reset the motor overload toggle turn the Power Switch to the OFF position and
unplug the unit from the power outlet. Allow 10 minutes (minimum) for motor
overload cut-out to cool and reset. Unit can then be plugged in and re-started.
• Replace blown fuse or reset circuit breaker. Do not use fuse or circuit
breaker with higher rating than specified for your branch circuit.
• Check for proper fuse; “Fusetron” type T is acceptable.
• Check for low voltage and proper extension cord size.
• Disconnect other applications from circuit. Operate
compressor on a dedicated circuit.
Check valve stuck open Remove and clean or replace.
Wrong wire gauge in cord or exces-
sive extension cord length
Check for proper gauge and extension cord length.
Loose electrical connections Contact authorized service center.
Paint spray on internal motor parts Have checked at service center. Do not operate compressor in the paint spray area
Possible defective motor Have checked at service center.
unplug or disconnect electrical supply to
the air compressor, bleed tank of pres-
sure, and allow the air compressor to cool.
