IMPORTANT SAFETY INSTRUCTIONS SAFETY INSTRUCTIONS PERTAINING TO A RISK OF FIRE, ELECTRIC SHOCK, OR INJURY TO PERSONS WARNING – When using tools, basic precautions should always be followed, including the following: General To reduce the risks of electric shock, fire, and injury to persons, read all the instructions before using the tool. Work area a. Keep the work area clean and well lighted. Cluttered benches and dark areas increase the risks of electric shock, fire, and injury to persons. c.
Tool use and care SAFETY a. 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 can lead to loss of control. b. 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. c. Do not use the tool if the trigger does not turn the tool on or off.
Specific Safety Instructions 3. Choice of triggering method is important. Check manual for triggering options. 4. Always assume the tool contains fasteners. 5. Do not point the tool toward yourself or anyone whether it contains fasteners or not. 6. Do not actuate the tool unless the tool is placed firmly against the workpiece. 20. Do not fire fasteners into a workpiece that has people, utility lines, or other objects behind or inside it. 21. Keep balance while using this tool.
Vibration Precautions 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.

Operating Instructions 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. SAFETY Inspect tool before use, looking for damaged, loose, and missing parts. If any problems are found, do not use tool until repaired. Workpiece and Work Area Set Up 2. Route the air hose along a safe route to reach the work area without creating a tripping hazard or exposing the air hose to possible damage.
Contact Safety Trip (Bump Fire) Mechanism Definition SAFETY The contact safety trip (or bump fire) mechanism allows rapid fire. Use the Mode Switch near the Trigger to change modes. The tool should only fire if the Safety Nosepiece is pressed against the workpiece and the trigger is pulled. It should fire again if the trigger is released and pulled OR if the safety is lifted and pressed against the workpiece again. The Tool should not fire if the Safety Nosepiece is not pressed against an object.
TO PREVENT SERIOUS INJURY FROM ACCIDENTAL OPERATION, BEFORE LOADING: • Wear ANSI-approved safety goggles with side shields. Other people in the work area must also wear ANSI-approved impact safety goggles with side shields. • Release the trigger. • Detach the air supply. • Attempt to fire the Tool into a piece of scrap wood to ensure that it is disconnected and is incapable of firing any fasteners. Note: Make sure nail type and angle are correct for nailer. 1.
