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.
Conden sation 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

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)

• 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

• Keep hands and body parts clear of

FIG. Q

FIG. R

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.

• Choice of triggering method is
important. Check the manual for triggering options.

CONTACT ACTION TRIGGER

• When using the contact action

FIG. T

trigger, be careful of unin tentional
double fires resulting from tool
recoil. Unwanted fasteners may be

driven if the contact trip is allowed to
accidentally re-contact the work surface.
(Fig. T)

TO AVOID DOUBLE FIRES:

• Do not engage the tool against the
work surface with a strong force.

• Allow the tool to recoil fully after each actuation.

• Use sequential action trigger.

• When “contact” actuating the nailer, always keep tool in

control. Inaccurate placement of tool can result in misdirected

discharge of a fastener.

SEQUENTIAL ACTION TRIGGER

• When using the sequential action

FIG. U

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.U)

• 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.

• DEPTH ADJUSTMENT: To reduce risk of serious injury
from accidental actuation when attempting to adjust depth,
ALWAYS;

• Disconnect air supply

• Avoid contact with trigger during adjustments

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:

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

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

• NIOSH/OSHA/MSHA respiratory protection.

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 D

EWALT 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

WARNING: Always wear proper eye [ANSI Z87.1 (CAN/CSA

Z94.3)] and hearing protection [ANSI S12.6 (S3.19)] when operating
this tool.

WARNING: The operator must not hold the trigger pulled on

contact trip tools 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. A contact trip tool may bounce from the recoil of driving a
fastener and an unwanted second fastener may be driven, possibly
causing injury.

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

or belt.

CONTACT TRIP (BLACK TRIGGER)

The common operating procedure on “Contact Trip” tools is for the

operator to contact the work to actuate the trip mechanism while
keeping the trigger pulled, thus driving a fastener each time the work
is contacted. This will allow rapid fastener placement on many jobs,
such as sheathing, decking and pallet assembly. All pneumatic tools
are subject to recoil when driving fasteners. The tool may bounce,
releasing the trip, and if unintentionally allowed to recontact the work
surface with the trigger still actuated (finger still holding trigger pulled)
an unwanted second fastener will be driven.

SEQUENTIAL TRIP (GRAY TRIGGER)

The Sequential Trip requires the operator to hold the tool against

the work before pulling the trigger. This makes accurate fastener
placement easier, for instance on framing, toe nailing and crating
applications.

The Sequential Trip allows exact fastener location without the

possibility of driving a second fastener on recoil, as described under
Contact Trip.

The Sequential Trip Tool has a positive safety advantage because it

will not accidentally drive a fastener if the tool is contacted against
the work – or anything else – while the operator is holding the trigger
pulled.

CONTACT TRIP OPERATION (BLACK TRIGGER)

When using the contact trip (black) trigger the tool contains a contact
trip that operates in conjunction with the trigger to drive a fastener.

There are two methods of operation to drive fasteners with a contact

trip tool.
SINGLE FASTENER PLACEMENT: To operate the tool in this
manner, first position the contact trip on the work surface, WITHOUT
PULLING THE TRIGGER. Depress the contact trip until the nose
touches the work surface and then pull the trigger to drive a fastener.
Do not press the tool against the work with extra force. Instead, allow
the tool to recoil off the work surface to avoid a second unwanted
fastener. Remove your finger from the trigger after each operation.
RAPID FASTENER OPERATION: To operate the tool in this manner,
hold the tool with the contact trip pointing towards but not touching
the work surface. Pull the trigger and then tap the contact trip against
the work surface using a bouncing motion. Each depression of the
contact trip will cause a fastener to be driven.

English

7

SEQUENTIAL TRIP OPERATION (GRAY TRIGGER)

When using the sequential trip (gray) trigger the tool contains a
contact trip that operates in conjunction with the trigger to drive a
fastener. To operate a sequential trip tool, first position the contact
trip on the work surface
WITHOUT PULLING THE TRIGGER. Depress the contact trip and
then pull the trigger to drive a fastener. As long as the contact trip
is contacting the work and is held depressed, the tool will drive a
fastener each time the trigger is depressed. If the contact trip is
allowed to leave the work surface, the sequence described above
must be repeated to drive another fastener.
