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
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.
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 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.Avoid unintentional starting. Be sure the trigger is released before connecting to the air supply. Do not carry the tool with your finger on the trigger or connect the tool to the air supply with the trigger pressed.
d.Do not overreach. Keep proper footing and balance at all times.
Proper footing and balance enables better control of the tool in unexpected situations.
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.
h.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.
i.Always assume that the tool contains fasteners. Do not point the tool toward yourself or anyone whether it contains fasteners or not.
j.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.
k.WARNING – Remove finger from the trigger when not driving fasteners.

Never carry the tool with finger on trigger, the tool is able to fire a fastener.
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 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.Do not use the tool if the trigger does 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.
d.Disconnect the tool from the air 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.
e.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.
f.Maintain the tool with care. A properly maintained tool reduces the risk of binding and is easier to control.
g.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.
h.Use only accessories that are identified by the manufacturer for the specific tool model. Use of an accessory not intended for use with the specific tool model, increases the risk of injury to persons.
i.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.
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.
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.
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.

23.Install in-line shutoff valve to allow immediate control over air supply in an emergency, even if a hose is ruptured.
24.Do not engrave or stamp anything into the housing to avoid weakening it.
25.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.)
26.The warnings and precautions discussed in this manual cannot cover all possible conditions and situations that may occur.
It must be understood by operator that common sense and caution are factors which cannot be built into this product, but must be supplied by operator.
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.
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.
