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 us- ing 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 explo- sive 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 do- ing and use common sense when operating the tool. Do not use the tool while tired or under the influ- ence of drugs, alcohol, or medica- tion. 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 switch is off before con- necting to the air supply. Do not carry the tool with your finger on the switch or connect the tool to the air supply with the switch on.

d.Remove adjusting keys and 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.

e.Do not overreach. Keep proper footing and balance at all times.

Proper footing and balance enables better control of the tool in unexpect- ed situations.

f.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. Wear a full face shield if you are producing metal filings or wood chips.

g.Always wear eye protec- tion. Wear ANSI-ap- proved safety goggles with side shields during use.

h.Always wear hearing protection when using the tool. Prolonged expo- sure to high intensity noise

is able to cause hearing loss.

Tool use and care

a.Avoid unintentional misfires. Be sure Trigger

(59) is in the OFF posi- tion when not in use and before plugging in. Do

not carry any tool with your finger on the Trigger, whether it is attached to an air source or not. Do not point tool towards yourself or anyone whether it contains nails or not.

b.Do not load nails with Trigger or safety depressed. Unintentional fir- ing may occur. Always assume Nailer contains fasteners.

c.Do not load fasteners when Nailer is connected to air hose. Always assume tool contains fasteners. Unin- tentional firing may occur.

d.Properly adjust Nailer angle to match corresponding fasteners before inserting nail strip. Failure to do so can cause Nailer to jam and lead to personal and/or property dam- age.

e.Fire nails into an appropriate work surface only. Do not attempt to fire

cleat nails or staples into surfaces too hard to penetrate. Do not drive cleat nails or staples on top of other cleat nails or staples, or at too steep an angle. Cleat nails and staples can ricochet, causing personal injury. Never fire this tool into the air or point it toward yourself or another person.

f.Hold tool away from head and body during use. Tool may kick back, causing injury.

g.Do not fire fasteners too close to edge of workpiece. They may split the workpiece and fly free, causing personal injury.

h.Carry tool safely. Carry tool by handle.

i.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 is able to lead to loss of control.

j.Do not force the tool. Use correct tool for application. The correct tool will do the job better and safer at the rate for which the tool is designed.

k.Disconnect the tool from the air source before making any adjust- ments, 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.

l.Store the tool when it is idle out of reach of children and other un- trained persons. A tool is dangerous in the hands of untrained users.

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

n.Check for misalignment or bind- 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.

o.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.

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 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 (70 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.

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.

Specific Safety Instructions

1.The warnings and precautions dis- cussed in this manual cannot cover all possible conditions and situations that may occur. It must be under- stood by the operator that common sense and caution are factors which cannot be built into this product, but must be supplied by the operator.

2.WARNING: Some dust created by power sanding, sawing, grinding, drill- ing, 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 chemi- cally treated lumber

Your risk from these exposures var- ies, 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.)

3.Take caution, as some woods contain preservatives such as copper chro- mium arsenate (CCA) which can be toxic. When nailing these materials, extra care should be taken to avoid inhalation and minimize skin contact.

4.WARNING: The brass components of this product contain lead, a chemi- cal known to the State of California to cause birth defects (or other repro- ductive harm). (California Health & Safety code ?? 25249.5, et seq.)

5.Only use with accessories rated to handle forces exerted by tool during operation. Other accessories not de- signed for the forces generated may break and forcefully launch pieces.

6.Attach all accessories properly to the tool before connecting the air sup- ply. A loose accessory may detach or break during operation.

7.Obey the manual for the air compres- sor used to power this tool.

8.Install in-line shutoff valve to allow immediate control over air supply in emergency, even if hose is ruptured.

9.Do not lay tool down until it has com- pletely stopped. Moving parts can grab surface and lead to control loss.

Vibration Precautions

This tool vibrates during use. Re- peated or long-term exposure to vibra- tion 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 regu- larly 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, ner- vous system disorders, diabetes, or

Raynaud???s Disease should not use this tool. If you feel any medical or physical symptoms related to vibra- tion (such as tingling, numbness, and white or blue fingers), seek medical advice as soon as possible.

2.Do not smoke during use. Nico- tine 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 dif- ferent 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.

an air valve that will allow the air tool to retain pressure and operate accidentally after the air supply is disconnected.

Note: Air flow, and therefore tool perfor- mance, can be hindered by under- sized air supply components.

3.The air hose must be long enough to reach the work area with enough extra length to allow free movement while working.

4.Close the in-line safety valve be- tween the compressor and the tool.

5.Turn on the air compressor according to the manufacturer???s directions and allow it to build up pressure until it cycles off.

6.Adjust the air compressor???s output regulator so that the air output is enough to properly power the tool, but the output will not exceed the tool???s maximum air pressure at any time. Adjust the pressure gradually, while checking the air output gauge to set the right pressure range.

7.Inspect the air connections for leaks. Repair any leaks found.

8.If the tool will not be used at this time, turn off and detach the air supply and safely discharge any residual air pressure.

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.

Joint Plate (86) lines up with the nut on Magazine. See Figure 5, above.

Replace and tighten the Adjuster

Knob.

3.Inspect Pin???s (34) location. See

Figure 6, below.

If you are driving 21?? angle nails, the Pin should be in the lower hole (position A). If you are driving 28?? or 34?? angle nails, the Pin should be in the upper hole (position B). If the Pin is in the wrong position, pull the Pin from its Washer (35), reposition the Bar Guide (36), and reinsert and secure the Pin and Washer. Before using Nailer, be sure Pin is properly secured.

1.The driving depth of a nail can be adjusted in two ways. First, by in- creasing or decreasing air pressure (never to exceed the maximum of 120 PSI). Secondly, by loosening the

Depth Screw (41) and adjusting the

Bracket A (40). We recommend you experiment in a scrap piece of mate- rial to determine how far to adjust the unit.

2.Attach air supply to Air Coupler. Start your air compressor and make sure it is set to between the recommended 70-120 PSI.

3.To fire, place the Safety Nosepiece of the Nailer on the workpiece. The

Nailer should not fire if the Safety

Nosepiece is not depressed. Once depressed, quickly squeeze the

Trigger once. Do not fire repeat- edly; nails could bounce off of one another causing injury. We recom- mend practicing with a piece of scrap material.

4.The Rubber Cover (43) provides a non-marring surface. If desired, the Rubber Cover may be removed to ex- pose the teeth on Safety Nosepiece.

Doing so provides a nonslip surface and can improve accuracy.

5.When finished, disconnect the Nailer from the air source.

Clearing Jams

WARNING! Anytime any maintenance or repairs are done (including clearing jams), wear ANSI-approved

impact safety goggles and appro- priate hearing protection. THEN:

a.Disconnect the Nailer from its air supply.

b.Empty the Magazine (79) com- pletely.

c.Try to fire the Nailer into a piece of scrap wood to ensure that there is no trapped air in the system.

d.Always leave Magazine open dur- ing maintenance. The Magazine is spring-loaded and may cause parts or a nail to fly out of Nailer.

1.If a nail is jammed in the discharge area, simply remove it with pliers.

2.If a nail is jammed in the magazine, pull the Tab (75) all the way back to the disengaged position. Using a screwdriver, attempt to release the

jammed nail by probing either or both

of the two openings in the maga- zine to release the nail. Pull out the jammed nail and the remainder of the nail strip that is still in the magazine.

3.Dispose of the remaining nail strip; it may be bent or damaged in some other way. Reload the magazine with a new nail strip.

4.Be careful. When pulling back the Tab, it will spring forward with
