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)

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 fasteners
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

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)

• 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 fasteners. (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,
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
fastener may follow the grain of the
wood (shiner), causing it to protrude
unexpectedly from the side of the work
material. Drive the fastener perpendicular
to the grain to reduce risk of injury. (Fig. N)
• Do not drive fasteners onto the heads
of other fasteners or with the tool at
too steep an angle. Personal injury
from strong recoil, jammed fasteners, or
ricocheted fasteners may result. (Fig. O)
• Be aware of material thickness when
using the stapler. A protruding fastener
may cause injury.
• Be aware that when the tool is being
utilized at pressures on the high end
of its operating range, fasteners can
be driven completely through thin or
very soft work material. Make sure the
pressure in the compressor is set so that
fasteners are set into the material and not
pushed completely through. (Fig. P)

• Keep hands and body parts clear of
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 stapler 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 fastener into
another fastener 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 stapling 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
trigger, be careful of unintentional
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 stapler, 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 trigger, do not actuate
the tool unless the tool is placed firmly against the
workpiece.
• 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

• Do not drive fasteners blindly into FIG. U
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.
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.

OPERATION
Preparing the Tool
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 stapler pointed away from yourself
and others. For safe operation, complete the following procedures
and checks before each use of the stapler.
CAUTION: NEVER spray or in any other way apply lubricants or
cleaning solvents inside the tool. This can seriously affect the life and
performance of the tool.
NOTE: These staplers are designed to be used without oil.
1. Before you use the stapler, be sure that the compressor tanks
have been properly drained.
2. Wear proper eye, hearing and respiratory protection.
3. Remove all fasteners from the magazine.
4. 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.
5. Check air supply. Ensure that air pressure does not exceed
recommended operating limits, refer to Tool Specifications.

Mode Selection
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: Keep fingers AWAY from trigger when not driving
fasteners to avoid accidental firing. NEVER carry tool with finger on
trigger. In contact mode tool will fire a fastener if safety is bumped
while trigger is depressed.
The DWSL18CAP features a selectable trigger system that allows the
user to choose between the following modes of operation
Sequential Trip
Sequential trip requires the operator to hold the contact trip against
the work surface before pulling the trigger. This makes accurate
fastener placement easier. The sequential trip allows exact fastener
placement 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
second fastener if the tool is contacted against the work or anything
else while the operator is holding the trigger pulled.
Contract Trip
The common operating procedure on contact trip tools is for the
operator to contact the work surface 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. 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 the trigger pulled) an unwanted second fastener will be driven.
TO CHANGE OPERATING MODES (FIG. 1–3)
WARNING: Disconnect air line from tool and remove fasteners
from magazine before making adjustments or personal injury may
result.
SEQUENTIAL TRIP ACTION
Use sequential action for intermittent nailing where very careful and
accurate placement is desired.
To operate the stapler in sequential action mode:
1. Rotate the trigger mode selector (B) FIG. 2
clockwise to the sequential action position
, as shown in Figure 2.
2. Fully depress nosepiece against the work
surface.
3. Pull trigger.
4. Release trigger.
5. Lift nosepiece off work surface.
6. Repeat steps 2 through 4 for next application.
WARNING: The contact trip needs to be depressed followed by a
trigger pull for each fastener followed by a release of both the contact
trip and trigger after each fastener.
CONTACT TRIP ACTION
Bump/contact action is intended for rapid nailing on flat, stationary
surfaces.
When using bump action, two methods are available: place
actuation and bump actuation.
Rotate the trigger mode selector (B) FIG. 3
counterclockwise to the contact action position
, as shown in Figure 3.
