Introduction

Congratulations on the purchase of your new DEWALT Air Com-

pressor! You can be assured that this tool has been constructed with

the highest level of precision and accuracy. Each component has been

rigorously tested to ensure the quality, endurance and performance of

this air compressor.

By reading and following the safety, operation, maintenance and

troubleshooting steps described in this manual, you will receive years

of trouble free operation.

The manufacturer reserves the right to make changes in price, color,

materials, equipment specifications or models at any time without

notice.

Inspection of Compressor

Inspect for signs of obvious or concealed freight damage. Report any

damage to the delivering freight carrier immediately. Be sure that all

Features

PILOT VALVE

Pilot valves are used to maintain a

constant pressure range while running

continuously. The pilot valve may be

used to operate a discharge line

unloader or an unloading device in the

compressor head. The D

EWALT compressor unloads through the com-

pressor head. Unloading occurs when the receivers (tanks) reach a

preset cut-out pressure. The pilot valve opens, actuating the unloading

device that allows the compressor to run in an unloaded mode. When

the tank pressure drops to the preset cut-in pressure, the pilot valve

closes allowing the unloading device to close and the compressor once

again pumps into the tanks.

English

Manual Lock: The manual lock allows you to manually unload the

compressor with air pressure in the tank. To operate the unloading

device in the head, rotate the flip lever to an in-line position (dashed

lines). Be sure to return lever to the loaded position after starting the

engine or the pump will not operate at preset pressures.

SAFETY RELIEF VALVE

This valve (A) is designed to prevent system failures

by relieving pressure from the system when the

compressed air reaches a predetermined level. The

valve is preset by the manufacturer and must not be

removed or modified in any way.

AIR INTAKE FILTER(S)

The filter(s) (B) are designed to clean air entering the

pump. To ensure the pump continually receives a clean,

cool, and dry air supply the filter(s) must always be

clean and the filter intake must be free from

obstructions.

AIR TANK DRAIN VALVE(S)

The drain valve(s) (C) are used to remove

moisture from the air tank after the air

compressor is shutoff.

TANK PRESSURE GAUGE

The tank pressure gauge (D) indicates air

pressure in the air tank.

REGULATED PRESSURE GAUGE

The regulated pressure gauge (E) indicates the

air pressure available at the outlet side of the

regulator. This pressure is controlled by the

regulator and is always less or equal to the air

tank pressure.

PRESSURE REGULATOR

The regulator knob (F) controls the air pressure

coming from the air tank.

Preparation For Use

INITIAL SET-UP:

Read safety instructions before setting-up air compressor.

CAUTION: Do not operate without lubricant or with inadequate

lubricant. D

EWALT is not responsible for compressor failure caused by

inadequate lubrication.

Compatibility

Air tools and accessories that are run off the compressor must be

compatible with petroleum based products. If you suspect that a

material is not compatible with petroleum products, an air line filter for

removal of moisture and oil vapor in compressed air is required.

NOTE: Always use an air line filter to remove moisture and oil vapor

when spraying paint.

English

Location

CAUTION: In order to avoid damaging the air compressor, do not

allow the unit to be tilted more than 10˚ when operating.

Place air compressor at least 3 feet away from obstacles that may

prevent proper ventilation. Keep unit away from areas that have dirt,

vapor and volatile fumes in the atmosphere which may clog and gum

up the intake filter and valves, causing inefficient operation.

HUMID AREAS

In frequently humid areas, moisture may form in the bare pump and

produce sludge in the lubricant, causing running parts to wear out

prematurely. Excessive moisture is especially likely to occur if the unit

is located in an unheated area that is subject to large temperature

changes. Two signs of excessive humidity are external condensation

on the bare pump when it cools down and a “milky” appearance in

compressor lubricant. You may be able to prevent moisture from

forming in the bare pump by increasing ventilation or operating for

longer intervals.

NOISE CONSIDERATIONS

Consult local officials for information regarding acceptable noise levels

in your area. To reduce excessive noise, use vibration mounts or

silencers, relocate the unit or construct total enclosures or baffle walls.

Contact a D

EWALT service center or call 1-800-4DEWALT for

assistance.

TRANSPORTING:

WARNING: Unit weighs more than 160 lbs. Do not move or lift

without assistance.

When transporting the compressor in a vehicle, trailer, etc. ensure that

the tanks are drained and the unit is secured and placed on a flat

horizontal surface. Use care when driving so to avoid tipping the unit

over in the vehicle. Damage can occur to the unit or surrounding items

if unit is tipped. Use a ramp if loading or unloading the unit from a

height of more than 12".

MOVING:

When moving the unit into a position for use, grasp handle grips at rear

of compressor, and lift compressor high enough so unit can be rolled

on the front tire.

WARNING: Ensure proper footing and use caution when rolling

compressor so that unit does not tip or cause loss of balance.

When location is reached slowly lower rear of compressor to ground.

ALWAYS STORE COMPRESSOR IN A HORIZONTAL POSITION,

ON ALL FOUR RUBBER MOUNTS.

NOTE: Should the unit tip over, hard starting and smoking will occur

due to oil spillage.

Air Inlet Filter

CAUTION: Do not operate without air inlet filter

General Requirements

The piping, fittings, receiver tank, etc. must be certified safe for at

least the maximum working pressure of the unit. Use hard welded or

threaded steel or copper pipes, cast iron fittings and hoses that are

certified safe for the units discharge pressure and temperature. Use

pipe thread sealant on all threads, and tighten joints thoroughly to

prevent air leaks. DO NOT USE PVC PLASTIC.

CONDENSATE DISCHARGE PIPING

If installing a condensate discharge line, the piping must be at least one

size larger than the connection, as short and direct as possible,

secured tightly and routed to a suitable drain point. Condensate must

be disposed of in accordance with local, state and federal laws and

regulations.

NOTE: All compressed air systems generate condensate that

accumulates in any drain point (e.g. tanks, filter, aftercoolers, dryers).

This condensate contains lubricating oil and/or substances which may

be regulated and must be disposed of in accordance with local, state,

and federal laws and regulations.

Les conditions indiquées ci-après peuvent affaiblir le réservoir et

entraîner une violente explosion du réservoir :

1. Le fait de ne pas drainer convenablement l'eau condensée du

réservoir, entraînant la corrosion et l'amincissement des

parois en acier du réservoir. Drainer le réservoir

quotidiennement ou après chaque utilisation. Si le réservoir

présente une fuite, le remplacer immédiatement par un nouveau

réservoir ou un nouvel équipement de compresseur.

2. Modifications apportées au réservoir du compresseur ou

tentatives de réparation. Ne jamais percer un trou dans le

réservoir ou ses accessoires, y faire de la soudure ou y apporter
