8. Always wear hearing protection
when using the tool.
Prolonged exposure to high intensity noise is able to cause hearing loss.
9. Risk of Electric Shock. This tool is not provided with an insulated gripping surface.
Contact with a ″live″ wire will also make exposed metal parts of the tool ″live″ and shock the operator.
10. Avoid body contact with grounded surfaces such as pipes, radiators,
ranges and refrigerators. There is an increased risk of electric shock if your body is grounded.
11. Explore the workpiece to avoid contact
with hidden wiring. Thoroughly investigate the workpiece for possible hidden wiring before performing work. Contact with live wiring will shock the operator.
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.
9. Always use proper guard with grinding wheel.
A guard reduces the risk of injury to persons from broken wheel fragments.

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-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.
3. Turn the tool's throttle or switch to the off position; refer to Operation section for description of controls.
4. Close the in-line shutoff 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.
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.
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.
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.
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: 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.
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.
