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.

Personal safety

Stay alert. Watch what you are do-a. ing 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.

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 (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.

Remove adjusting keys and d. 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.

is able to cause hearing loss.

Tool use and care

Avoid unintentional misres. a. Al-

though Nailer has a full sequential safety trip mechanism, do not point tool towards yourself or anyone whether it contains

nails or not.

Do not load fasteners when Nailer b. is connected to air hose. Always

assume tool contains fasteners. Unin-

tentional ring may occur.

Fire nails into an appropriate work c. surface only. Do not attempt to re

nails into surfaces too hard to penetrate. 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.

Hold tool away from head and d. body during use. Tool may kick

back, causing injury.

Do not re nails too close to edge e.

of workpiece. They may split the

workpiece and y free, causing personal injury.

Carry tool safely. f. Carry tool by handle.

Use clamps or another practical g. 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.

Do not force the tool. h. Use correct tool for application. The correct tool

will do the job better and safer at the

rate for which the tool is designed.

Disconnect the tool from the air i. source before making any adjustments, 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.

Store the tool when it is idle out of j. reach of children and other untrained persons. A tool is dangerous

in the hands of untrained users.

Maintain the tool with care. k. Keep tool clean. A properly maintained tool, reduces the risk of binding and is easier to control.

Check for misalignment or bind-l. 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.

Use only accessories that are m.

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

Tool service must be performed a.

only by qualied repair personnel.

When servicing a tool, use only b. identical replacement parts. Use only authorized parts.

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 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.

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.

The warnings and precautions dis-1. cussed 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.

WARNING:2. 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 lter out microscopic

particles. (California Health & Safety Code § 25249.5, et seq.)

mance, can be hindered by under-

sized air supply components.

The air hose must be long enough 3.

to reach the work area with enough

extra length to allow free movement

while working.

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.
