Important Safety Information (Continued)

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.

d.Use safety equipment. A dust mask,non-skidsafety shoes and a hard hat must be used for the applicable conditions.

Ensuring that the tool is used only when the operator and all

other personnel in the work area are wearing ANSI Z87 eye protection equipment, and when required, other

appropriate protection equipment such as head, hearing

and foot protection equipment. Serious eye or permanent hearing loss could result.

e. Always wear hearing protection when using the tool.Prolonged exposure to high intensity noise is able to cause hearing loss.

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.Always assume that the tool contains fasteners.

Do not point the tool toward yourself or anyone whether it contains fasteners or not.

Do not drop or throw the tool. Dropping

or throwing the tool can result in damage that will make the tool unusable or unsafe. If the tool has been dropped or thrown, examine the tool closely for bent, cracked or broken parts and air leaks. STOP and repair before using or serious injury could occur.

Avoid long extended periods of work with the nailer. Stop using the nailer if you feel pain in

hands or arms.

Hold tool by insulated gripping surface when performing an operation where the tool or

fastener may contact hidden wiring. Contacting a “live” wire will make exposed metal parts of the tool “live” and shock the operator.

Never place hands or any other body parts in the nail discharge area of the nailer.The nailer might eject a fastener and

could result in death or serious personal injury.

Electrical Safety

Replace batteries only with same size batteries. Do not mix old and

new batteries. Using wrong size batteries can create a risk of fire or injury.

The front end of the tool may be made “live” if the tool comes

into contact with live wiring in the wall.TO PREVENT ACCIDENTAL ELECTRICAL SHOCK, HOLD TOOL ONLY BY THE SOFT GRIP HANDLE.

Tool Use and Care

a.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.

Disconnect the tool from the air source before making adjustments, doing tool maintenance,

clearing jams, touching the safety yoke, leaving work area, loading, or unloading the tool. Such precautionary measures reduce the risk of injury to persons.

b.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.

c.Maintain the tool with care. A properly maintained tool reduces the risk of problems and is easier to control.

d.Use only those fasteners listed in the “Fastener Interchange Information” section on page 16 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.

e.Always work in a well-ventilatedarea.Wear OSHAapproved dust mask.

Always disconnect the tool from the power source when unattended, performing any

maintenance or repair, clearing a jam, loading, unloading , or moving the tool to a new location.

Always fit tool with a fitting or hose coupling on or near the tool in such a manner that all

compressed air in the tool is discharged at the time the fitting or hose coupling is disconnected. Do not use a check valve or any other fitting which allows air to remain in the nailer. Death or serious personal injury could occur.

Never carry the nailer by the air hose or pull the hose to move the nailer or a compressor.

Keep hoses away from heat, oil and sharp edges. Replace any hose that is damaged, weak or worn. Personal injury or tool damage could occur.

Set-Up

Lubrication

This nailer requires no lubrication for normal operation. However, lubrication willnot harm the tool.

The work surface can become damaged by excessive lubrication.

Minimum Components Required For Hook-up

AIR COMPRESSOR: The air compressor must be able to maintain a minimum of 70 psi when the nailer is being used. An inadequate air supply can cause a loss of power and inconsistent driving (see Chart 1).

PRESSURE REGULATOR: A pressure regulator is required to control the operating pressure of the nailer between 70 psi and 120 psi.

AIR SUPPLY HOSE: Always use air supply hoses with a minimum working pressure rating equal to or greater than the pressure from the power source, or 150 psi, whichever is greater. Use 1/4 inch air hose for runs up to 50 feet. Use 3/8 inch air hoses for 50 ft. run or longer (see Figure 7 and Chart 2).

Hook-upInstructions For Nailer to Air Supply

Figure 8 shows the recommended hookup for the nailer.

NOTE: For better performance, install a 3/8 inch quick plug (1/4 inch NPT threads) with an inside diameter of 0.315 inch (8 mm) on the nailer and a 3/8 inch quick coupler on the air hose.

1.With ON/OFF switch in OFF position, plug compressor into electrical outlet.

2.Close pressure regulator by turning all the way to the left. Turn compressor ON and let it pump all the way up to automatic shut-offpressure.

3.Attach air hose to regulator outlet. Adjust pressure regulator by turning to the right so that outlet pressure is between 70 psi to 120 psi.

4.Load fasteners into nailer (See Loading/Unloading the Nailer section on page 11).

5.Point the nailer in a safe direction while attaching to air hose.

6.Nailer is ready for use. You may need to adjust outlet pressure to achieve proper fastener depth.
