INSTRUCTIONS
INSTRUCTIONS PERTAINING
TO A RISK OF FIRE,
ELECTRIC SHOCK, OR
INJURY TO PERSONS
WARNING – When using
tools, basic precautions
should always be followed,
including the following:
General
a. To reduce the risks of electric
shock, re, and injury to persons,
read all the instructions before us-
ing the tool.
Work area
a. Keep the work area clean and well
lighted. Cluttered benches and dark
areas increase the risks of electric
shock, re, and injury to persons.
b. Do not operate the tool in explo-
sive atmospheres, such as in the
presence of ammable liquids,
gases, or dust. The tool is able to
create sparks resulting in the ignition
of the dust or fumes.

SKU 98917 For technical questions, please call 1-800-444-3353. Page 3
c. Keep bystanders, children, and
visitors away while operating the
tool. Distractions are able to result in
the loss of control of the tool.
Personal safety
a. Stay alert. Watch what you are do-
ing and use common sense when
operating the tool. Do not use the
tool while tired or under the inu-
ence of drugs, alcohol, or medica-
tion. A moment of inattention while
operating the tool increases the risk
of injury to persons.
b. Dress properly. Do not wear loose
clothing or jewelry. Contain long
hair. Keep hair, clothing, and
gloves away from moving parts.
Loose clothes, jewelry, or long hair
increases the risk of injury to persons
as a result of being caught in moving
parts.
c. Avoid unintentional starting. Be
sure the Trigger (56) is off before
connecting to the air supply. Do not
carry the tool with your nger on the
Trigger or connect the tool to the air
supply with the Trigger on.
d. Remove adjusting keys and
wrenches before turning the tool
on. A wrench or a key that is left at-
tached to a rotating part of the tool
increases the risk of personal injury.
e. Do not overreach. Keep proper
footing and balance at all times.
Proper footing and balance enables
better control of the tool in unexpect-
ed situations.
f. Use safety equipment. A
dust mask, non-skid safety
shoes and a hard hat must
be used for the applicable conditions.
Wear heavy-duty work gloves during
use. Wear a full face shield if you are
producing metal lings or wood chips.
g. Always wear eye protec-
tion. Wear ANSI-ap-
proved safety goggles with
side shields during use.
h. Always wear hearing
protection when using
the tool. Prolonged expo-
sure to high intensity noise
is able to cause hearing loss.
Tool use and care
a. Avoid unintentional misres. Al-
though Nailer has a full
sequential safety trip
mechanism, do not point
tool towards yourself or
anyone whether it contains
nails or not.
b. Do not load fasteners when Nailer
is connected to air hose. Always
assume tool contains fasteners. Unin-
tentional ring may occur.
c. Fire nails into an appropriate work
surface only. Do not attempt to re
nails into surfaces too hard to pen-
etrate. Do not drive nails on top of
other nails, or at too steep an angle.
Nails can ricochet, causing personal
injury. Never re this tool into the air
or point it toward yourself or another
person.
d. Hold tool away from head and
body during use. Tool may kick
back, causing injury.
e. Do not re nails too close to edge
of workpiece. They may split the

SKU 98917 For technical questions, please call 1-800-444-3353. Page 4
workpiece and y free, causing per-
sonal injury.
f. Carry tool safely. Carry tool by
handle.
g. Use clamps or another practical
way to secure and support the
workpiece to a stable platform.
Holding the work by hand or against
the body is unstable and is able to
lead to loss of control.
h. Do not force the tool. Use correct
tool for application. The correct tool
will do the job better and safer at the
rate for which the tool is designed.
i. Disconnect the tool from the air
source before making any adjust-
ments, changing accessories, or
storing the tool. Such preventive
safety measures reduce the risk
of starting the tool unintentionally.
Turn off and detach the air supply
and safely discharge any residual
air pressure before leaving the work
area.
j. Store the tool when it is idle out of
reach of children and other un-
trained persons. A tool is dangerous
in the hands of untrained users.
k. Maintain the tool with care. Keep
tool clean. A properly maintained tool,
reduces the risk of binding and is
easier to control.
l. Check for misalignment or bind-
ing of moving parts, breakage of
parts, and any other condition that
affects the tool’s operation. If dam-
aged, have the tool serviced before
using. Many accidents are caused
by poorly maintained tools. There is a
risk of bursting if the tool is damaged.
m. Use only accessories that are
identied by the manufacturer for
the specic tool model. Use of an
accessory not intended for use with
the specic tool model, increases the
risk of injury to persons.
Service
a. Tool service must be performed
only by qualied repair personnel.
b. When servicing a tool, use only
identical replacement parts. Use
only authorized parts.
c. Use only the lubricants supplied
with the tool or specied by the
manufacturer.
Air source
a. Never connect to an air
source that is capable of
exceeding 120 PSI. Over
pressurizing the tool may
cause bursting, abnormal operation,
breakage of the tool or serious injury
to persons. Use only clean, dry,
regulated compressed air at the rated
pressure or within the rated pressure
range as marked on the tool (60 to
120 PSI). Always verify prior to using
the tool that the air source has been
adjusted to the rated air pressure or
within the rated air-pressure range.
b. Never use oxygen, carbon dioxide,
combustible gases or any bottled
gas as an air source for the tool.
Such gases are capable of explosion
and serious injury to persons.

Specic Safety Instructions
1. The warnings and precautions dis-
cussed in this manual cannot cover
all possible conditions and situations
that may occur. It must be under-
stood by the operator that common
sense and caution are factors which
cannot be built into this product, but
must be supplied by the operator.
2. WARNING: Some dust created by
power sanding, sawing, grinding, drill-
ing, 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 or other masonry products
• Arsenic and chromium from chemi-
cally treated lumber
Your risk from these exposures var-
ies, 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 lter out microscopic
particles. (California Health & Safety
Code § 25249.5, et seq.)
3. Take caution, as some woods contain
preservatives such as copper chro-
mium arsenate (CCA) which can be
toxic. When nailing these materials,
extra case should be taken to avoid
inhalation and minimize skin contact.
4. WARNING: The brass components
of this product contain lead, a chemi-
cal known to the State of California
to cause birth defects (or other repro-

SKU 98917 For technical questions, please call 1-800-444-3353. Page 6
ductive harm). (California Health &
Safety code § 25249.5, et seq.)
5. Only use with accessories rated to
handle forces exerted by tool during
operation. Other accessories not de-
signed for the forces generated may
break and forcefully launch pieces.
6. Attach all accessories properly to the
tool before connecting the air sup-
ply. A loose accessory may detach or
break during operation.
7. Obey the manual for the air compres-
sor used to power this tool.
8. Install in-line shutoff valve to allow
immediate control over air supply in
emergency, even if hose is ruptured.
9. Do not lay tool down until it has com-
pletely stopped. Moving parts can
grab surface and lead to control loss.
10. The pressure setting must not exceed
the job site regulations/restrictions.
11. The pressure setting on any Nailer
should not exceed 90 PSI when
working with workpieces that have a
thickness of less than 1-3/4”.
Vibration Precautions
This tool vibrates during use. Re-
peated or long-term exposure to vibra-
tion may cause temporary or permanent
physical injury, particularly to the hands,
arms and shoulders. To reduce the risk of
vibration-related injury:
1. Anyone using vibrating tools regu-
larly or for an extended period should
rst be examined by a doctor and
then have regular medical check-
ups to ensure medical problems are
not being caused or worsened from
use. Pregnant women or people
who have impaired blood circulation
to the hand, past hand injuries, ner-
vous system disorders, diabetes, or
Raynaud’s Disease should not use
this tool. If you feel any medical or
physical symptoms related to vibra-
tion (such as tingling, numbness, and
white or blue ngers), seek medical
advice as soon as possible.
2. Do not smoke during use. Nico-
tine reduces the blood supply to the
hands and ngers, increasing the risk
of vibration-related injury.
3. Wear suitable gloves to reduce the
vibration effects on the user.
4. Use tools with the lowest vibration
when there is a choice between dif-
ferent processes.
5. Include vibration-free periods each
day of work.
6. Grip tool as lightly as possible (while
still keeping safe control of it). Let
the tool do the work.
7. To reduce vibration, maintain tool as
explained in this manual. If abnormal
vibration occurs, stop immediately.

Air Supply
TO PREVENT
EXPLOSION:
Use only clean, dry, regulated,
compressed air to power this
tool. Do not use oxygen,
carbon dioxide, combustible
gases, or any other bottled
gas as a power source for this
tool.
1. Incorporate an in-line oiler, shut-off
valve, regulator with pressure gauge,
and lter for best service, as shown in
the diagram above. An in-line shut-
off valve is an important safety
device because it controls the air
supply even if the air hose is rup-
tured.
Note: If an automatic oiler system is not
used, add a few drops of Pneumatic
Tool Oil to the airline connection be-
fore operation. Add a few more drops
after each hour of continual use.
2. Attach an air hose to the compres-
sor’s air outlet. Connect the air hose
to the air inlet of the tool. Other com-
Rev 09l

ponents, such as a connector and
quick coupler, will make operation
more efcient, but are not required.
WARNING! TO PREVENT SERIOUS
INJURY FROM ACCIDENTAL
OPERATION:
Do not install a female quick
coupler on the tool. Such a coupler
contains an air valve that will allow
the air tool to retain pressure and
operate accidentally after the air
supply is disconnected.
Note: Air ow, and therefore tool perfor-
mance, can be hindered by under-
sized air supply components.
3. The air hose must be long enough
to reach the work area with enough
extra length to allow free movement
while working.
4. Close the in-line safety valve be-
tween the compressor and the tool.
5. Turn on the air compressor according
to the manufacturer’s directions and
allow it to build up pressure until it
cycles off.
6. Adjust the air compressor’s output
regulator so that the air output is
enough to properly power the tool,
but the output will not exceed the
tool’s maximum air pressure at any
time. Adjust the pressure gradually,
while checking the air output gauge
to set the right pressure range.
7. Inspect the air connections for leaks.
Repair any leaks found.
8. If the tool will not be used at this time,
turn off and detach the air supply
and safely discharge any residual air
pressure.
Note: Residual air pressure should not be
present after the tool is disconnected
from the air supply. However, it is a
good safety measure to attempt to
discharge the tool in a safe fashion
after disconnecting to ensure that the
tool is disconnected and unpowered.
To Attach An Air Connector:
1. Attach a 1/4” Connector (not
included) to the Air Plug (83) prior to
operation.
2. Wrap about 3” of pipe thread seal
tape (not included) onto threads of
the Connector before attaching it to
the Air Plug.
