Parts & Features

See figures below tor reference.

Air Intake Filter , , , ^ ^ ^

Provides clean air to the pump and must always be kept free of debris. Check on a daily basis or before each use.

Regulator Gauge

Indicates the outgoing air pressure to the tool and is controlled
by the regulator.

Tank Pressure Gauge

indicates the reserve air pressure in the tank.

Pressure Switch

This controls the power to the motor and also the
cut-in/cut-out pressure settings. This switch serves
as the Auto-On/Off positions for the unit.

Pressure Relief Valve

The pressure relief vaive iocated on the
side of the pressure switch, is designed to
automatically release compressed air when
the air compressor reaches cut-out pressure.
The reieased air should only escape

momentarily and the valve should then close.

__________________

Tank Safety Valve

Used to allow excess tank pressure to
escape into the atmosphere. This valve
should only open when the tank pressure
is above the maximum rated pressure.

R^ulator

me air pressure coming from the air tank is
controlled by the regulator. To increase the
pressure turn the knob clockwise and to
decrease the pressure turn the knob
counterclockwise.

Quick Connect

Offers a quick release feature for attaching and removing the air hose.

Tank Drain Valve

Used to drain condensation from the air tank. Located at bottom of tank.

Check Valve . . , *

When the pump is not in operation the valve closes to retain air pressure inside the tank. An internal component.

Installation & Assembly

A WARNING

The air compressor should be turned off and unplugged from
the power source before any maintenance is performed as
well as the air bled from the tank and the unit allowed time
to cool. Personal injuries could occur from moving parts,
electrical sources, compressed air or hot surfaces. The
regulator 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 instruction.

Quick Connect Assembly

1. Before assembly be sure that the
Quick Connect (Q.C.) threads have a
sealant applied from the factory to prevent
leaks around the threads. If no sealant is

present, wrap the threaded portion with

Teflon tape.

2. Attach the Q.C. assembly to the air compressor by

aligning the Q.C. threads to the regulator on the manifold.
Be certain to align the threads before tightening to prevent
thread damage.

3. The assembly should turn clockwise 1 to 1.5 revolutions

after hand-tightening with a 13/16ths size wrench. To prevent
damage and leaks, do not
over-tighten.

To Install the Air Intake Filter

Remove the air intake filter from the
poly bag and thread it onto the head
of the compressor as shown.

A CAUTION

Do not attempt to start the air compressor without first adding
oil to the crankcase. Serious damage can result unless filled
with oil. The pump is shipped without oil from the factory.
Only use non-detergent oils since multi-viscosity motor oils

leave carbon deposits on pump components, thus reducing

performance and compressor life.

A WARNING

Drain the tank to release all tank air

pressure before removing the oil fill cap.

Be sure the air vent in the oil fill cap {see

figure to the right) is free from debris.

If air vent is blocked, pressure can build
in crankcase causing damage to the
compressor and possible personal injury.

Lubrication and Oil

Remove the oil fill cap by turning it
counter-clockwise by hand. Fill the
compressor pump with an air compressor
oil such as SAE-30 non-detergent (API
CG/CD Heavy Duty) oil at slow intervals
until the oil reaches the center of the red
circle in the sight glass ( see figure above).
Use SAE-10 during extreme winter conditions.

Location of the Air Compressor

The air compressor should always be located in a clean,
dry, and well ventilated environment. The unit should have

at minimum, 12 inches of space on each side. The air fitter
intake should be free of any debris or obstructions. Check

the air filter on a daily basts to be sure it is clean and in

working order.

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. (See the figure below.) 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.

A WARNING

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 oonnect 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. 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
property 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 circuit having a nominal rating

of 120 volts and is factory-equipped with a specific electric
cord and plug to permit connection to a proper electric circuit.
Make sure that the product is connected to an outlet having
the same configuration as the plug. No adapter should be

used with this product. If the product must be reconnected

for use on a different type of electric circuit, qualified service

personnel should make the reconnection.

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 25 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.
