Item 98580

Personal Safety

1.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.

2.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.

3.Avoid unintentional starting. Be sure the switch is off before connecting 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.

4.Remove adjusting keys and wrenches before turning the tool on. A wrench or a key that is left attached to a rotating part of the tool increases the risk of personal injury.

5.Do not overreach.

Keep proper footing and balance at all times.

Proper footing and balance enables better control of the tool in unexpected situations.

6.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.

7.Always wear eye protection.

Wear ANSI-approvedsafety goggles.

8.Always wear hearing protection when using the tool.

Prolonged exposure to high intensity noise is able to cause hearing loss.

Tool Use and Care

1.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.

2.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.

3.Do not use the tool if the switch does not turn the tool on or off. Any tool that cannot be controlled with the switch is dangerous and must be repaired.

4.Disconnect the tool from the air 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, safely discharge any residual air pressure, and release the throttle and/or turn the switch to its off position before leaving the work area.

5.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.

6.Maintain the tool with care. Keep a cutting tool sharp and clean. A properly maintained tool, with sharp cutting edges reduces the risk of binding and is easier to control.

7.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.

8.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.

Specific Safety Instructions

1.The warnings and precautions discussed 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.

2.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-basedpaints

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.)

3.Obey the manual for the air compressor used to power this tool.

4.Install an in-lineshutoff valve to allow immediate control over the air supply in an emergency, even if a hose is ruptured.

5.Use this tool with both hands only. Using tools with only one hand can result in loss of control.

6.Do not lay the tool down until it has come to a complete stop. Moving parts can grab the surface and pull the tool out of your control.

Vibration Precautions

This tool vibrates during use. Repeated or long-termexposure to vibration may cause temporary or permanent physical injury, particularly to the hands, arms and shoulders. To reduce the risk ofvibration-relatedinjury:

1.Anyone using vibrating tools regularly or for an extended period should first be examined by a doctor and then have regular medical check-upsto 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-relatedinjury.

3.Wear suitable gloves to reduce the vibration effects on the user.

4.Use tools with the lowest vibration when there is a choice.

5.Include vibration-freeperiods 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.

Save these instructions.

Initial Tool Set Up/Assembly

Read the entire Important Safety Information section at the beginning of this manual including all text under subheadings therein before set up or use of this product.

Note: For additional information regarding the parts listed in the following pages, refer to the Assembly Diagram near the end of this manual.

Note: This air tool may be shipped with a protective plug covering the air inlet. Remove this plug before set up.

Air Supply

To prevent serious injury from explosion:

Use only clean, dry, regulated, compressed air to power this tool. Do not use oxygen, carbon dioxide, combustible gases,

or any other bottled gas as a power source for this tool.

1.Incorporate a filter, regulator with pressure gauge, oiler, in-lineshutoff valve, and quick coupler for best service, as shown on Figure A on page 8 and Figure B on page 9.An in-line shutoff

ball valve is an important safety device because it controls the air supply even if the air hose

is ruptured. The shutoff valve should be a ball valve because it can be closed quickly.

Note: If an automatic oiler system is not used, add a few drops of Pneumatic Tool Oil to the airline connection before operation. Add a few more drops after each hour of continual use.

2.Attach an air hose to the compressor's air outlet. Connect the air hose to the air inlet of the tool. Other components, such as a coupler plug

and quick coupler, will make operation more efficient, but are not required.

WARNING! To prevent serious injury from accidental operation:

Do not install a female quick coupler on the tool.

Such a coupler contains 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 performance, can be hindered by undersized air supply components. The air hose must be long enough to reach

the work area with enough extra length to allow free movement while working.

3.Turn the tool's throttle or switch to the off position; refer to Operation section for description of controls.

4.Close the in-lineshutoff valve between 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, safely discharge any residual air pressure, and release

the throttle and/or turn the switch to its off position to prevent accidental operation.

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 not powered.
