IMPORTANT SAFETY 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,
fire, and injury to persons, read all the
instructions before using the tool.
Work area
SAFETYOPERATIONMAINTENANCE SETUP
a. Keep the work area clean and well lighted.
Cluttered benches and dark areas increase the
risks of electric shock, fire, and injury to persons.
b. Do not operate the tool in explosive atmospheres,
such as in the presence of flammable liquids,
gases, or dust. The tool is able to create sparks
resulting in the ignition of the dust or fumes.
Personal safety
a. Stay alert. Watch what you are doing and
use common sense when operating the tool.
Do not use the tool while tired or under the
influence of drugs, alcohol, or medication.
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. Do not overreach. Keep proper
footing and balance at all times.
Proper footing and balance enables better
control of the tool in unexpected situations.
c. Keep bystanders, children, and visitors away
while operating the tool. Distractions are able
to result in the loss of control of the tool.
d. 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.
e. Always wear eye protection.
Wear ANSI-approved safety goggles
with side shields.
f. Do not attach the hose or tool to your body.
Attach the hose to the structure to reduce the
risk of loss of balance if the hose shifts.
g. WARNING – Do not fire fastener on top of another
fastener. This is able to cause the fastener to be
deflected and hit someone, or cause the tool to
react and result in a risk of injury to persons.

Tool use and care
a. 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
SAFETY OPERATION MAINTENANCESETUP
is unstable and can lead to loss of control.
b. Do not force the tool. Use the correct tool for the
application. The correct tool will do the job better
and safer at the rate for which the tool is designed.
c. Disconnect the tool from the air source before
making adjustments, doing tool maintenance,
or leaving work area. Such precautionary
measures reduce the risk of injury to persons.
d. Store the tool when it is idle out of reach
of children and other untrained persons.
A tool is dangerous in the hands of untrained users.
Service
a. Tool service must be performed only
by qualified repair personnel.
b. When servicing a tool, use only identical
replacement parts. Use only authorized parts.
e. Maintain the tool with care.
A properly maintained tool reduces the risk
of binding and is easier to control.
f. Check for misalignment or binding of moving
parts, breakage of parts, and any other condition
that affects the tool’s operation. If damaged, 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.
g. Use only those fasteners listed in the
Specifications chart of this manual.
Fasteners not identified for use with this tool by the
tool manufacturer are able to result in a risk of injury
to persons or tool damage when used in this tool.
c. Use only the lubricants supplied with the
tool or specified by the manufacturer.
Air source
a. Never connect to an air source that is
capable of exceeding 200 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. 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.

Fasteners can ricochet causing personal injury.
the housing to avoid weakening it.
12. Do not fire fasteners too close to the edge of
a workpiece. They may split the workpiece
and fly free, causing personal injury.
13. Keep clear of the workpiece near the area being
fastened. Fasteners may bend sideways during
firing, causing them to exit the workpiece at an
unexpected point, causing personal injury.
14. Transport tool safely. Always disconnect
air supply when moving the tool.
15. Hold tool away from head and body. During operation
the tool may kick back causing injury.
16. Do not fire fasteners into a workpiece that has people,
utility lines, or other objects behind or inside it.
17. Keep balance while using this tool.
Keep area below clear if working in an elevated
location, and secure air hose to prevent falls
from bystanders accidentally pulling on it.
18. Obey the manual for the air compressor
used to power this tool.
19. Install an in-line shutoff valve to allow
immediate control over the air supply in an
emergency, even if a hose is ruptured.
20. Do not engrave or stamp anything into
21. 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 or
other masonry products
• 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.
(California Health & Safety Code § 25249.5, et seq.)
WARNING: The brass components of
this product contain lead, a chemical
known to the State of California to cause
birth defects (or other reproductive harm).
(California Health & Safety code § 25249.5, et seq.)
22. The warnings and precautions discussed in this
manual cannot cover all possible conditions and
situations that may occur. It must be understood
by the operator that common sense and caution
are factors which cannot be built into this
product, but must be supplied by the operator.
SAFETYOPERATIONMAINTENANCE SETUP
Vibration Precautions
This tool vibrates during use.
Repeated or long-term exposure to vibration 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 regularly or for an
extended period should first 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, nervous system disorders, diabetes,
or Raynaud’s Disease should not use this tool.
If you feel any symptoms related to vibration (such
as tingling, numbness, and white or blue fingers),
seek medical advice as soon as possible.
SAVE THESE INSTRUCTIONS.
2. Do not smoke during use. Nicotine reduces
the blood supply to the hands and fingers,
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 different 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.
