SPECIFICATIONS
• 3.5 Peak HP
• 11 Gallon Air Tank
• Oil Lubricated Direct Drive Pump
• Cast-iron Cylinder
• Maximum Pressure: 125 PSI
• Power: 115V, 60 Hz, 15 Amps
• Air Delivery: 4.7 SCFM output @ 40 PSI / 3.0 SCFM output @ 90 PSI
• Duty Cycle: 50%
• Thermal Overload Protection for Safety
• High Flow Regulator for Precision Air Flow Control
• Dual Pressure Gauges
• Weight: 84 lbs. (38 kg)
Duty Cycle:
Duty cycle refers to the percentage of time a compressor can safely run within a given amount of time expressed as a ratio. Oil lubricat-
ed compressors are typically rated at a 50% duty cycle, meaning that the compressor motor can run about 50% of the total time it is
being used to supply air to a tool. During the “on” time, the motor is running to pressurize the tank. During the “off” time, the motor is
stopped and the tools are running off on the pressurized air stored in the tank. If your air tools are draining pressure off of the tank too
quickly, the compressor motor must run more than 50% of the time the compressor is in use. This can lead to overheating and will sig-
nificantly shorten the life of the compressor.
INSTALLATION AND LOCATION
The compressor must be used on a stable level surface. The air compressor must be used in a clean and well-ventilated area. The com-
pressor requires an unobstructed airflow and must be located a minimum of 20 inches from any walls or other obstructions.

GROUNDING INSTRUCTIONS
This product should 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.
The plug must be plugged into an outlet that is properly installed and grounded in accordance with all local codes and ordinances.
DANGER
Improper installation of the grounding plug can result in a risk of electric shock. If repair or replacement of the cord 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 with-
out yellow stripes is the grounding wire.
Figure 1
This product is for use on a nominal 120-volt circuit and has a three-prong grounding plug that
looks like the plug illustrated in Figure 1. Make sure that the product is connected to an outlet
having the same configuration as the plug. No adapter could be used with this product.
Grounded Outlet Box
Grounded Outlet
The use of a GFCI outlet is strongly recommended. The third prong is to be used to ground the
tool and provide protection against electrical shock. Never remove the third prong.
115 Volts

CAUTION
Extension Cords - Alltrade does not recommend the use on an extension cord with this product as this may result in the loss of power
and overheating of the motor. An additional air hose should be used instead of an extension cord.
However, if the use of an extension cord is unavoidable, use only UL listed three wire extension cords that have three-pronged ground-
ing type plugs and three prong receptacles that accept the tool's plug. Improper use of extension cords may cause inefficient operation
of your tool, which can result in overheating. Be sure your extension cord is rated to allow sufficient flow to motor. Refer to the guide
below for minimum gauge required for extension cords.

51 to 100 Feet
Use of an extension cord rated to carry the current the tool will draw is very important, especially when the power source is at great
distance. An extension cord of insufficient rating will cause a drop in line voltage, resulting in power loss and causing the motor to
overheat.
Guard against electrical shock. Avoid body contact with grounded services such as pipes, radiators, ovens, stoves, and refrigerator
enclosures. If not properly grounded, this power tool can incur the potential hazard of light trickle shock, particularly when used in
damp locations. If an electrical shock occurs, there is the potential of a secondary hazard such as your hands contacting an operating
air tool.

MOISTURE IN COMPRESSED AIR
Moisture is a normal by-product of compressing air. As the moisture builds during compressor use, it can be carried though the air
hose. When using a paint spray gun or sandblasting gun, the use of a special filter to remove moisture from the air line is highly rec-
ommended. Moisture in the compressed air will cause water spots in paint jobs and cause blasting media to clog the sandblasting gun.

Possible Cause
Possible Solution
When in the Start/Stop
option, motor runs continu-
ously:
Motor/Pressure switch does not shut off
motor when air compressor reaches "cut-out" tion. If the motor does not shut off, unplug the air
pressure and safety relief valve activates.
Move the motor/pressure switch to the "OFF" posi-
compressor. If the electrical contacts are welded
together, replace the pressure switch.
Air compressor is incorrectly sized.
Limit the air pressure to the capacity of the air com-
pressor. Either use a smaller tool or a larger air com-
pressor.
Poor ventilation.
Dirty cooling fins.
Relocate the air compressor to an area with an
ample supply of cool, dry, and well-circulated air is
available.
Overheating:
Clean the outer surfaces of the cooling fins on the
pump and motor assembly.
