FEATURES (FIG. 1)

AUTO/OFF SWITCH
Place this switch (L) in the AUTO (I) position to provide automatic power to the pressure

switch and OFF (O) to remove power at the end of each use.
PRESSURE SWITCH

The pressure switch (H) 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.
SAFETY VALVE
If the pressure switch does not shut off the air compressor at its cut-out pressure setting,

the safety valve (G) will protect against high pressure by popping out at its factory set
pressure (slightly higher than the pressure switch cut-out setting).

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.

TANK PRESSURE GAUGE
The tank pressure gauge (K) indi-cates the reserve air pressure in the tank.
REGULATED PRESSURE GAUGE
The regulated pressure gauge (D) indicates the air pressure available at the outlet side of

the regulator. This pressure is controlled by the regulator.
REGULATOR

The regulator (F) controls the air pressure shown on the regulated pressure gauge. Pull the
knob out and turn clockwise to increase pressure and counterclockwise to decrease pressure.
When the desired pressure is reached push knob in to lock in place. The regulated pressure

range is 7-150 psi.

AWARNING: Risk of Bursting. Too much air pressure causes a hazardous risk of bursting.

Check the manufacturer's maximum pressure rating for air tools and accessories. The
regulator outlet pressure must never exceed the maximum pressure rating.

UNIVERSAL QUICK CONNECT BODIES
The universal quick connect body (E) accepts the three most popular styles of quick connect

plugs: industrial, automotive, and ARC. One hand push-to-connect operation makes
connections simple and easy. The two quick connect bodies allow the use of two tools at

the same time.
DRAIN VALVE

The drain valve (M) is located at the base of the air tank and is used to drain condensation
at the end of each use. See Draining Air Tank under Maintenance.

COOLING SYSTEM
This compressor contains an advanced design cooling system. It is normal for this fan to

blow air through the vent holes in large amounts. The cooling system is working when air
is expelled.

AIR COMPRESSOR PUMP
The 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.

Grounding Instructions (Fig. 2)

`&WARNING: Risk of electrical shock. In the event of a short circuit, grounding reduces the

risk of shock by providing an escape wire for the electric current. This air compressor must
be properly grounded.

The portable air compressor is equipped with a cord having a grounding wire with an

appropriate grounding plug.

1. The cord set and plug (R) with this unit contains a grounding pin (S).This plug MUST be
used with a grounded outlet ([).

IMPORTANT: The outlet being used must be installed and grounded in accordance with all
local codes and ordinances.

2. Ensure the outlet being used has the same configuration as the grounded plug. DO NOT
USE AN ADAPTER.

3. Inspect the plug and cord before each use. Do not use if there are signs of damage.

4. If these grounding instructions are not completely understood, or if in doubt as to

whether the compressor is properly grounded, have the installation checked by a

qualified electrician.

ADANGER: Risk of electrical shock. IMPROPER GROUNDING CAN RESULT IN

ELECTRICAL SHOCK.

• Do not modify the plug provided. If it does not fit the available outlet, a correct outlet
should be installed by a qualified electrician.
Repairs to the cord set or plug MUST be made by a qualified electrician.

Extension Cords

If an extension cord must be used, be sure it is:

• 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

• in good condition

• plug is not worn

• no longer than 50 feet (15.2 m)

12 gauge (AWG) or larger. (Wire size increases as gauge number decreases. 10 AWG and
8 AWG may also be used. DO NOT USE 14 OR 16 AWG.)

NOTICE: Risk of property damage. The use of an undersized extension cord 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. Always use a minimum 3/8"

(9.5 ram) or greater air hose rated at 300 psi.

Voltage and Circuit Protection

Refer to the Voltage and Minimum Branch Circuit Requirements under Specifications.
ACAUTION: Risk of Overheating. Certain air compressors can be operated on a 15 amp

circuit if the following conditions are met.

= Voltage supply to circuit must comply with the National Electrical Code.
= Circuit is not used to supply any other electrical needs.
= Extension cords comply with specifications.
= Circuit is equipped with a 15 amp circuit breaker or 15 amp time delay fuse.

NOTE: If compressor is connected to a circuit protected by fuses, use only time delay
fuses. Time delay fuses should be marked "D" in Canada and "T" in the U.S.

If any of the above conditions cannot be met, or if 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.

automatically shuts off, protecting your air tank from pressure higher than its capacity. The

high pressure at which the motor shuts off is called cut-out pressure.
Branch Circuit: The circuit carrying electricity from electrical panel to outlet.
Duty Cycle: 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.

Troubleshooting Guide

This section provides a list of the more frequently encountered malfunctions, their causes

and corrective actions. The operator or maintenance personnel can perform some corrective
actions, and others may require the assistance of a qualified DEWALT technician or your
dealer.
