the safety is bumped while the trigger is
depressed.
Only fire fasteners into the work surface; never
into materials too hard to penetrate.
Grip the tool firmly to maintain control while
allowing the tool to recoil away from work surface
as the fastener is driven. If the safety element is
allowed to recontact the work surface before the
trigger is released, an unwanted fastener will be
fired.
Do not drive fasteners on top of other fasteners
or with the tool at too steep an angle. Fasteners
can ricochet causing personal injury.
Do not drive fasteners close to the edge of the
work piece. The work piece may split, allowing
the fastener to fly free or ricochet and cause
personal injury.
FOR CONTACT ACTUATION TOOLS ONLY, Do
not use on scaffoldings or ladders or for tasks in
which changing location involves the use of
scaffoldings, stairs, ladders, and the like. Do not
use for specific tasks transportation safety
systems or vehicles and wagons.

Compressor
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.
General operation
Depending on the CFM draw of the tools being operated, your new air
compressor can be used for operating paint sprayers, air tools, grease
guns, air brushes, caulking guns, sandblasters, inflating tires and plastic
toys, spraying weed killer and insecticides, etc. An air pressure regulator is
usually necessary for most of these applications.
How it works
To compress air, the pistons move up and down in the cylinder. Air enters
through the valve inlet on the down stroke and the discharge valve remains
closed. Air is compressed on the up stroke. The inlet valve closes and the
compressed air is forced out through the discharge valve, through the
check valve, and into the air receiver.
Working air is not available until the compressor has raised the air receiver
pressure above that required at the service connection. The air inlet filter
openings must be kept clear of obstructions, which could reduce the air
compressor’s air delivery.

Electrical Requirements (cont’d)
Extension cords
Using extension cords is not recommended. The use of extension cords will
cause voltage to drop, resulting in power loss to the motor and overheating.
Instead of using an extension cord, increase the working reach of the air
hose by attaching another length of hose to its end. Attach additional
lengths of hose as needed. If an extension cord must be used:
z Use 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
z The extension cord must be in good condition
z The extension cord must be no longer than 50 feet
z 14-gauge (AWG) or larger. (Wire size locations as gauge number
decreases. 12 AWG and 10 AWG may also be used. (DO NOT USE 16
OR 18 AWG.)
Voltage and circuit protection
This air compressor can be operated on a 15 amp circuit if the following
conditions are met:
z Voltage supply to the circuit must comply with the National Electrical
Code.
z The circuit is not used to supply any other electrical needs.
z Extension cords comply with the above specifications.
z The circuit must be equipped with a 15-amp circuit breaker or 15 amp
time delay fuse. Time delay fuses should be marked “D” in Canada and
“T” in the US.
If any of the above conditions cannot be met, or if the operation of the
compressor repeatedly causes interruption of the power, it may be
necessary to operate it from a 20 amp circuit. It is not necessary to change
the cord set.

Compressor (cont’d)
Installation and location
Locate the compressor in a clean, dry, well-ventilated area. The compressor
should be located 12 to 18 inches from a wall or any other obstruction that
might interfere with the air flow through the fan blade belt wheel. Place the
compressor on a firm, level surface. The air compressor is designed with
heat dissipation fins that allow for proper cooling. Keep the fins or other
parts that collect dirt or dust clean. A clean compressor runs cooler and
provides longer service. Do not place rags, containers or other materials on
top of the compressor.
Controls
Become familiar with these controls before operating the unit.
z ON/AUTO/OFF Switch: Turn this switch ON to provide automatic power
to the pressure switch and OFF to remove power at the end of each use.
z 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.
z Safety Valve: If the pressure switch dies not shut off the air compressor
at its “cut-out” pressure setting, the safety valve will protect against high
pressure by “popping out” at its factory-set pressure (slightly higher than
the pressure switch “cut-out” setting).
z Tank Pressure Gauge: The tank pressure gauge indicates the reserve
air pressure in the tank.
z Outlet Pressure Gauge: The outlet pressure gauge 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.
z Regulator: Controls the air pressure shown on the outlet pressure
gauge. Turn regulator knob clockwise to increase pressure and
counterclockwise to decrease pressure.
z Universal Quick-Connect Body: The universal quick-connect body
accepts the three most popular styles or quick-connect plugs: industrial,
automotive (Tru-flate), and ARO. One hand push-to-connect operation
makes connections simple and easy.

Compressor (cont’d)
Controls (cont’d)
z Cooling system: This compressor contains an advanced design
cooling system that includes an engineered fan that blows air through
the vent holes in large amounts.
z Air Compressor 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.
z Drain Valve: The drain valve is located at the base of the air tank and is
used to drain condensation at the end of each use.
z 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.
