WARNING – When using tools, basic
precautions should always be followed, including the following:
General
To reduce the risks of electric shock, a.
re, and injury to persons, read all the
instructions before using the tool.
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 pressed.
Do not overreach. Keep proper d. footing and balance at all times.
Proper footing and balance enables better control of the tool in unexpected situations.
Work area
Keep the work area clean and well a. lighted. Cluttered benches and dark
areas increase the risks of electric
shock, re, and injury to persons.
Do not operate the tool in explosive b. 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.
Keep bystanders, children, and c. visitors away while operating the tool.
Distractions are able to result in the loss of control of the tool.
Personal safety
Stay alert. Watch what you are a. doing and use common sense when operating the tool. Do not use the
tool while tired or under the inuence
of drugs, alcohol, or medication. A moment of inattention while operating the tool increases the risk of injury to persons.
e. 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.
f. Always wear eye protection.
Wear ANSI-approved safety
goggles with side shields.
g.
Always wear hearing
protection when using the
tool. Prolonged exposure to
high intensity noise is able to cause hearing loss.
Do not attach the hose or tool to your h. body. Attach the hose to the structure to
reduce the risk of loss of balance if the hose shifts.
Always assume that the tool contains i. fasteners. Do not point the tool toward
yourself or anyone whether it contains fasteners or not.
Dress properly. Do not wear loose b. 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.
Avoid unintentional starting. Be c. sure the trigger is released before
40073, & 97521
WARNING – Do not re fastener on j. top of another fastener. This is able to
cause the fastener to be deected and
hit someone, or cause the tool to react and result in a risk of injury to persons.
WARNING – Remove nger from the k. trigger when not driving fasteners. Never carry the tool with nger on
trigger, the tool is able to re a fastener.

Tool use and care
Use clamps or another practical way a. to secure and support the workpiece to a stable platform. Holding the work
by hand or against the body is unstable and can lead to loss of control.
Do not force the tool.b. 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.
Do not use the tool if the trigger does c. not turn the tool on or off. Any tool that
cannot be controlled with the trigger is dangerous and must not be used until repaired.
specic tool model, increases the risk of
injury to persons. Use only those fasteners listed in the i.
Specications chart of this manual. Fasteners not identied 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.
Service
Tool service must be performed only a.
by qualied repair personnel.
When servicing a tool, use only b. identical replacement parts. Use only authorized parts.
Disconnect the tool from the air d. source before making adjustments, doing tool maintenance, clearing jams, touching the safety nosepiece, leaving work area, loading, or unloading the tool. Such precautionary
measures reduce the risk of injury to persons.
Store the tool when it is idle out of e. reach of children and other untrained persons. A tool is dangerous in the
hands of untrained users. Maintain the tool with care.f. A properly
maintained tool reduces the risk of binding and is easier to control.
Check for misalignment or binding g. 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.
Use only the lubricants supplied c.
with the tool or specied 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.
Never use oxygen, carbon dioxide, b. combustible gases or any bottled gas as an air source for the tool. Such
gases are capable of explosion and serious injury to persons.
Use only accessories that are h.
identied by the manufacturer for the specic tool model. Use of an
accessory not intended for use with the

Obey the manual for the air compressor 22. used to power this tool.
Install an in-line shutoff valve to allow 23. immediate control over the air supply in an emergency, even if a hose is ruptured.
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:
Do not engrave or stamp anything into 24. the housing to prevent weakening of the housing.
WARNING: Some dust created by 25. 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 lter out
microscopic particles. (California Health & Safety Code § 25249.5, et seq.)
WARNING: The brass components of 26. 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.) The warnings and precautions discussed 27.
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.
Anyone using vibrating tools regularly 1.
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, 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
ngers), seek medical advice as soon as
possible. Do not smoke during use. Nicotine 2.
reduces the blood supply to the hands
and ngers, increasing the risk of
vibration-related injury. Wear suitable gloves to reduce the 3.
vibration effects on the user. Use tools with the lowest vibration when 4.
there is a choice between different processes.
Include vibration-free periods each day 5. of work.
Grip tool as lightly as possible (while still 6. keeping safe control of it). Let the tool do the work.
To reduce vibration, maintain tool as 7. explained in this manual. If abnormal vibration occurs, stop immediately.

MAINTENANCE
TO PREVENT
SERIOUS INJURY FROM ACCIDENTAL OPERATION, BEFORE ANY MAINTENANCE OR REPAIRS ARE DONE (including
clearing jams):
Wear ANSI-approved safety
goggles with side shields. Other people in the work area must also wear ANSI-approved impact safety goggles with side shields.
