AIR POWER TOOL PRECAUTIONS
WARNING! Immediately switch off the tool if any of the following occurs:
• Malfunction of the air inlet, air compressor or damage to the air supply hose.
• The switch or trigger is broken.
• The drill bit moves in an unsafe way.
1. Ensure air source matches the pressure rating of the tool’s motor (see Specifications).
2. Make sure the power switch is in the OFF position before connecting the tool to the air source.
3. Do not place the tool down until the drill bit has stopped moving. The drill bit may catch the
surface of work material and wrench itself free, causing injury to the user or others in the
work area.
4. Never use a tool with a cracked or worn drill bit. Change the drill bit before using.
5. Do not start the tool when the drill bit is touching the work piece.
6. Always use both hands when operating the tool, unless the tool is designed for single hand use.
7. Hold tool by insulated gripping surfaces when performing an operation where it may contact
hidden wiring or its own cord. Contact with a "live" wire will electrify exposed metal parts and
shock the operator.
8. Before using the tool on a work piece, test the tool by running it at the highest no-load speed
for at least 30 seconds in a safe position. Stop immediately if there is any abnormal vibration or
wobbling that could indicate poor installation of the drill bit. Check the tool to determine
the cause.
9. Take work breaks to prevent the tool’s motor from overloading and/or overheating.
10. When the tool is in operation, keep hands away from the drill bit and the area it is
being applied to.
11. Do not use the tool on any material containing asbestos.
12. Do not touch the drill bit or the surface that has been cut with this tool immediately after use.
The surface will be hot and may cause an injury.
13. Do not allow persons who are not familiar with the tool or have not read these instructions to
use the tool.

VIBRATION PRECAUTIONS
1. 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.
2. 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 by or worsened from tool use.
3. If you feel any medical symptoms related to vibrations (such as tingling, numbness, and white
or blue fingers), seek medical attention as soon as possible.
4. DO NOT use this tool if one of the following applies:
a. Pregnant
b. Impaired blood circulation to the hands
c. Past hand injuries
d. Nervous system disorders
e. Diabetes
f. Raynaud’s Disease
5. Do not smoke while operating the tool. Nicotine reduces the blood flow to the hands and
fingers, increasing the risk of vibration-related injury.
6. Wear suitable gloves to reduce the effects of vibration.
7. Use the tool with the least amount of vibration, when there is a choice between
different processes.
8. Do not use for extended periods. Take frequent breaks to when using this tool.

SPECIFIC SAFETY PRECAUTIONS
1. When drilling deep holes, periodically remove the drill bit from the workpiece to allow debris to
clear out from the bit.
2. Do not exceed air pressure of 90 PSI when using this tool.
WARNING! Exceeding the maximum pressure rating of 90 PSI will drastically reduce the life
of the tool and potentially cause serious injury to the operator.
3. Do not use quick disconnect couplings when installing this tool. See the section titled
Installation for correct setup.
4. Always shut off air supply, drain hose of air pressure, and disconnect the tool from the air
supply when not in use, or making any adjustments or repairs.
TOOL USE AND CARE
1. Use the correct tool for the job. Do not force a tool or attachment to do the work of a larger
industrial tool. Maximize tool performance and safety by using the tool for its intended task.
2. This tool was designed for a specific function. Do not modify or alter this tool or use it for an
unintended purpose.
3. Securely hold this tool using both hands, unless it is designed for single hand use. Using a tool
with only one hand can result in loss of control.
4. Maintain tools with care (see Maintenance).
5. Remove adjusting keys and wrenches from the tool before operation or connecting it to a power
source. A wrench or key that is left attached to a rotating part of the tool increases the risk of

AIR COMPRESSOR
Ensure the compressor used with the tool can supply the required Cubic Feet per Minute at the required
PSI (see Specifications).
1. Use proper size and type of air pressure line
and fittings.
2. Use only clean, dry, regulated compressed air at the
rated range as marked on the tool.
CAUTION! Do not use an air source besides an air
compressor to power this tool.
3. Always use an air regulator, an in-line filter and
a moisture trap in your compressed air system.
These accessories will increase the tool’s life and
keeps the tool in good working condition. See the
diagram for recommended components of an
air line.
4. Avoid using an air hose that is too long. The longer
the hose, the lower the pressure that reaches the tool, possibly causing it to cease functioning.
As well, a longer hose can become a tripping hazard.
5. Air tool CFM consumption ratings are based upon a 25% duty cycle. If you require continuous
duty, a larger compressor is required.
AIR SOURCE INSTALLATION
WARNING! Never use pure oxygen, carbon dioxide, combustible gases or any bottled gas as an air
source for a tool. Such gases are capable of causing an explosion and serious injury to persons.
1. Set the air pressure regulator on the air compressor to the recommended PSI level (see
Specifications). Do not exceed the tool recommended air pressure. Excess pressure could
result in damage to the tool, to your workpiece or serious injury.
2. Prepare a standard 1/4 in. air connector for use with your tool. Wrap the threaded portion of
the air connector with thread seal tape. Wrap in a clockwise direction so it will not unravel when
attaching to a quick connector. Attach it to the tool air inlet and tighten.
3. Attach a standard quick connector to the air source’s hose. Attach the air hose to the
tool’s air connector.
4. Check the air line and its connections for air leaks. Do not use the tool until you have repaired
all air leaks.
