debris, collation material, or dust

which could harm operator’s eyes.

The operator and all those persons in the

general area should wear safety glasses

with permanently attached side shields.

Approved safety glasses are imprinted

with the characters “Z87.1”. It is the

employer’s responsibility to enforce the

use of eye protection equipment by the

tool operator and other people in the work

area. (Fig. A)

• Always wear appropriate personal

hearing and other protection during

use. Under some conditions and duration

of use, noise from this product may

contribute to hearing loss. (Fig. A)

• Use only clean, dry, regulated air.

Condensation from an air compressor can

rust and damage the internal workings of

the tool. (Fig. B)

• Regulate air pressure. Use air

pressure compatible with ratings on

the nameplate of the tool. (Not to

exceed 120 psi, 8.3 bar) Do not connect

the tool to a compressor rated at over

200 psi. The tool operating pressure must

never exceed 200 psi even in the event of

regulator failure. (Fig. C)

English

• Only use air hose that is rated for a maximum working

pressure of at least 150 PSI (10.3 BAR) or 150% of the

maximum system pressure, which ever is greater. (Fig. D)

• Do not use bottled gases to power this FIG. E

FIG. F

FIG. G

tool. Bottled compressed gases such as

oxygen, carbon dioxide, nitrogen, hydrogen,

propane, acetylene or air are not for use

with pneumatic tools. Never use

combustible gases or any other reactive

gas as a power source for this tool. Danger

of explosion and/or serious personal injury

may result. (Fig. E)

• Use couplings that relieve all pressure

from the tool when it is disconnected

from the power supply. Use hose

connectors that shut off air supply from

compressor when the tool is disconnected.

(Fig. F)

• Disconnect tool from air supply when

not in use. Always disconnect tool

from air supply and remove fasteners

from magazine before leaving the

area or passing the tool to another

operator. Do not carry tool to another

work area in which changing location

involves the use of scaffoldings, stairs,

ladders, and the like, with air supply

connected. Do not make adjustments,

remove magazine, perform maintenance or clear jammed

fasteners while connected to the air supply. If the contact trip is

adjusted when the tool is connected to the air supply and nails are

loaded, accidental discharge may occur. (Fig. G)

• Connect tool to air supply before loading fasteners, to

prevent a fastener from being fired during connection. The

tool driving mechanism may cycle when tool is connected to

the air supply. Do not load fasteners with trigger or contact trip

depressed, to prevent unintentional firing of a fastener.

• Do not remove, tamper with, or FIG. H

FIG. I

FIG. J

otherwise cause the tool, trigger, or

contact trip to become inoperable.

Do not tape or tie trigger or contact trip in

the ON position. Do not remove spring

from contact trip. Make daily inspections

for free movement of trigger and contact

trip. Uncontrolled discharge could result.

• Inspect tool before use. Do not

operate a tool if any portion of the tool,

trigger, or contact trip is inoperable,

disconnected, altered, or not working

properly. Leaking air, damaged parts

or missing parts should be repaired or

replaced before use. (Fig.H)

• Do not alter or modify the tool in any

way. (Fig. I)

• Always assume that the tool contains

fasteners.

• Do not point the tool at co-workers

or yourself at any time. No horseplay!

Work safe! Respect the tool as a working

implement. (Fig. J)

English

• Keep bystanders, children, and visitors away while operating

a power tool. Distractions can cause you to lose control. When

tool is not in use, it should be locked in a safe place, out of the

reach of children.

• Remove finger from trigger when

not driving fasteners. Never carry

tool with finger on trigger. Accidental

discharge could result. Using the trigger

lock-off will prevent accidental discharge.

• Do not overreach. Maintain proper

footing and balance at all times. Loss of

balance may cause cause personal injury.

(Fig. K)

• Make sure hose is free of obstructions

or snags. Entangled or snarled hoses can

cause loss of balance or footing.

• Use the tool only for its intended use.

Do not discharge fasteners into open

air, concrete, stone, extremely hard

woods, knots or any material too hard

for the fastener to penetrate. Do not

use the body of the tool or top cap as

a hammer. Discharged fasteners may

follow unexpected path and cause injury.

(Fig. L)

• Always keep fingers clear of contact

trip to prevent injury from inadvertent

release of nails. (Fig. M)

• Refer to the Maintenance and Repairs

sections for detailed information on

the proper maintenance of the tool

• Always operate the tool in a clean,

FIG. P

FIG. N

FIG. O

lighted area. Be sure the work surface

is clear of any debris and be careful not

to lose footing when working in elevated

environments such as rooftops.

• Do not drive fasteners near edge

of material. The workpiece may split

causing the fastener to ricochet, injuring

you or a co-worker. Be aware that the nail

may follow the grain of the wood (shiner),

causing it to protrude unexpectedly from

the side of the work material. Drive the

nail perpendicular to the grain to reduce

risk of injury. (Fig. N)

• Do not drive nails onto the heads

of other fasteners or with the tool

at too steep an angle. Personal injury

from strong recoil, jammed fasteners, or

ricocheted nails may result. (Fig. O)

• Be aware of material thickness when

using the nailer. A protruding nail may

cause injury.

• Be aware that when the tool is being

utilized at pressures on the high end

of its operating range, nails can be

driven completely through thin or

very soft work material. Make sure

the pressure in the compressor is set so

that nails are set into the material and not

pushed completely through. (Fig. P)

FIG. K

FIG. S

immediate work area. Hold workpiece

with clamps when necessary to keep

hands and body out of potential harm. Be

sure the workpiece is properly secured

before pressing the nailer against the

material. The contact trip may cause the

work material to shift unexpectedly.

(Fig.Q)

• Do not use tool in the presence of

flammable dust, gases or fumes. The

tool may produce a spark that could

ignite gases causing a fire. Driving a nail

into another nail may also cause a spark.

(Fig.R)

• Keep face and body parts away from

back of the tool cap when working

in restricted areas. Sudden recoil can

result in impact to the body, especially

when nailing into hard or dense material.

(Fig. S)

• Grip tool firmly to maintain control

while allowing tool to recoil away

from work surface as fastener is

driven. In “Contact Actuation Mode” if

contact trip is allowed to recontact work

surface before trigger is released an

unwanted fastener will be fired.

• When using the sequential action FIG. T

trigger, do not actuate the tool

unless the tool is placed firmly

against the workpiece.

• Do not drive nails blindly into walls,

floors or other work areas. Fasteners

driven into live electrical wires, plumbing,

or other types of obstructions can result

in injury. (Fig.T)

• Stay alert, watch what you are

doing and use common sense when

operating a power tool. Do not use tool while tired or under

the influence of drugs, alcohol, or medication. A moment

of inattention while operating power tools may result in serious

personal injury.

WARNING: Some dust created by power sanding, sawing,

grinding, drilling, and other construction activities contains chemicals

known to the State of California to cause cancer, birth defects or other

reproductive harm. Some examples of these chemicals are:

• lead from lead-based paints,

• crystalline silica from bricks and cement and other masonry

products, and

• arsenic and chromium from chemically-treated lumber.

Your risk from these exposures varies, depending on how often you

do this type of work. To reduce your exposure to these chemicals:

work in a well ventilated area, and work with approved safety

equipment, such as those dust masks that are specially designed to

filter out microscopic particles.

WARNING: ALWAYS USE SAFETY GLASSES. Everyday

eyeglasses are NOT safety glasses. Also use face or dust mask

if operation is dusty. ALWAYS WEAR CERTIFIED SAFETY

EQUIPMENT:

English

• ANSI Z87.1 eye protection (CAN/CSA/Z94.3),

• ANSI S12.6 (S3.19) hearing protection,

• NIOSH/OSHA/MSHA respiratory protection.

OPERATION

Preparing the Tool (Fig. 2, 3)

WARNING: Read the section titled Important Safety Instructions

at the beginning of this manual. Always wear eye and ear protection

when operating this tool. Keep the nailer pointed away from yourself

and others. For safe operation, complete the following procedures

and checks before each use of the nailer.

1. Before you use the nailer, be sure that the compressor tanks

have been properly drained.

2. Lubricate the tool following these directions:

a. Use DEWALT pneumatic tool oil or a non-detergent S.A.E. 20

weight oil. DO NOT use detergent oil or additives as they will

damage o-rings and rubber parts.

b. Use a filter-regulator-lubricator in the air line between the

compressor and the tool when possible.

c. If a lubricator is not available, add 5 to 10 drops of oil in the air

fitting a least twice a day or every 4 hours of use.

FIG. 2 FIG. 3

3. Wear proper eye, hearing and respiratory protection.

4. Remove all fasteners from the magazine.

5. Check for smooth and proper operation of contact trip and

pusher assemblies. Do not use tool if either assembly is not

functioning properly. NEVER use a tool that has the contact trip

restrained in the up position.

6. Check air supply. Ensure that air pressure does not exceed

recommended operating limits, refer to Tool Specifications.

7. Connect air hose.

8. Check for audible leaks around valves and gaskets. Never use a

tool that leaks or has damaged parts.

WARNING: To reduce the risk of personal injury, disconnect tool

from air supply before performing maintenance, clearing a jammed

fastener, leaving work area, moving tool to another location or

handing the tool to another person.

Trigger (Fig. 1, 4)

WARNING: The operator must not hold the trigger pulled except

during fastening operation, as serious injury could result if the trip

accidentally contacted someone or something, causing the tool to

cycle.

WARNING: Keep hands and body away from the discharge area

of the tool.

WARNING: Never use rafter hook to hang tool from body, clothing

or belt.

The sequential triggering system gets its name from the “sequence”

required to drive a fastener.

1. Sequential Triggering: offers a positive safety advantage since it

will not accidentally drive a fastener if the tool is bumped against

any surface or anybody while the operator is holding the tools

with the trigger pulled.

English

2. Sequential Triggering: allows “place nailing” without the

possibility of driving a second, unwanted fastener on recoil.

DEWALT offers only one mode of operation with this tool.

NOTE: This tool operates sequentially, it’s operation is unique from

all other DEWALT tools. The moveable nose (D), which acts as the

contact trip, is in the “depressed” position at rest to allow visibility of

the nail points used for positive placement. When the tip of the nail is

placed in the preformed metal connector hole (G) and the trigger is

pulled, the moveable nose moves out from the tool to detect the work

surface. If the moveable nose does not detect the work surface close

to the nose of the tool, the tool will not actuate.

WARNING: To avoid serious injury from fasteners and flying debris

when installing metal connectors using the mcn nailer:

• Use only genuine DEWALT metal connector nails.

• Metal connector nails are not designed to penetrate metal. When

installing metal connectors, always place the exposed point of

the metal connector nail into the metal connector’s pre-formed

hole, and orient so the nail is perpendicular to the hole before

attempting to drive a fastener.
