Note: For additional information regarding the parts listed in the following pages, refer
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. Connect a regulator valve, an in-line shut off valve and 1/4” NPT air hose (all sold separately) to the Quick Coupler. Use thread tape on all threaded connections.
The air hose must be long enough to reach the work area with enough extra length to allow free movement while working. An in-line shutoff ball valve is an important safety device because it controls air supply even if air hose is ruptured. The shutoff valve should be a ball valve because it can be closed quickly. See pages 8 and 9 for
Air Tool Setup procedures.
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.

tool. Other components, such as coupler plug and industrial-grade quick coupler, will make operation more efficient, but are not required.
WARNING! TO PREVENT SERIOUS
INJURY FROM ACCIDENTAL
OPERATION: Do not install a quick
coupler on the tool. 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 work area with enough extra length to allow free movement.
4. Release Trigger (32).
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 pressure gradually, while checking the air output gauge to set the right pressure.
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 tool will not be used at this time, turn off and detach air supply, safely discharge any residual air pressure, and release 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.
Work Piece and Work Area Set Up
1. Designate a work area that is clean and well-lit. The work area must not allow access by children or pets to prevent distraction and injury.
2. Route the air hose along a safe path to reach the work area without creating a tripping hazard or exposing the air hose to possible damage. The air hose must be long enough to reach the work area with enough extra length to allow free movement while working.
3. Secure loose workpieces using a vise or clamps (not included) to prevent movement while working.
4. There must not be hazardous objects
(such as utility lines or foreign objects) nearby that will present a hazard while working.

(90 days if used by a professional contractor or if used as rental equipment). This warranty does not apply to damage due directly or indirectly, to misuse, abuse, negligence or accidents, repairs or alterations outside our facilities, 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

To take advantage of this warranty, the product or part must be returned to us with transportation charges prepaid. Proof of purchase date and an explanation of the complaint must accompany the merchandise. If our inspection verifies the defect, we will either repair or replace the product at our election or we may elect to refund the purchase price if we cannot readily and quickly provide you with a replacement. We will return repaired products at our expense, but if we determine there is no defect, or that the defect resulted from causes not within the scope of our warranty, then you must bear the cost of returning the product.
This warranty gives you specific legal rights and you may also have other rights which vary from state to state.
