SAFETY

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.

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.

Air Supply

TO PREVENT 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.

SAFETY

1.Incorporate a filter, regulator with pressure gauge, oiler, in-line shutoff 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 into the airline connection before operation.

Add a few more drops after each hour of continual use.

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

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.

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

4.Release the tool???s trigger.

5.Close the in-line safety valve between the compressor and the tool.

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

7.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.

8.The air pressure setting must not exceed job site regulations/restrictions. The air pressure setting must not exceed 90 PSI when being used with work pieces that have a thickness of less than 1-3/4???.

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

10.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 trigger 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 unpowered.
