Vibration Precautions

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.

SAFETY OPERATION MAINTENANCESETUP

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.

SAVE THESE INSTRUCTIONS.

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

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.

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 10
and Figure B on page 11. 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.

SAFETYOPERATIONMAINTENANCE SETUP

4. Release the tool’s trigger and empty its magazine.

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
workpieces 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.

and warrants to the original purchaser that this product is free from defects in materials and workmanship for the
period of 90 days from the date of purchase. This warranty does not apply to damage due directly or indirectly,
to misuse, abuse, negligence or accidents, repairs or alterations outside our facilities, criminal activity, improper
installation, normal wear and tear, or to lack of maintenance. We shall in no event be liable for death, injuries
to persons or property, or for incidental, contingent, special or consequential damages arising from the use of
our product. Some states do not allow the exclusion or limitation of incidental or consequential damages, so the
above limitation of exclusion may not apply to you. THIS WARRANTY IS EXPRESSLY IN LIEU OF ALL OTHER

If our inspection verifies the defect, we will either repair or replace the product at our election or we may

return repaired products at our expense, but if we determine there is no defect, or that the defect resulted
