3.3 Adjusting Depth of Drive
The tool features a tool-free depth adjustment wheel to control how deep the fasteners are driven into the material.
- Locate the depth adjustment wheel near the nose of the tool.
- Rotate the wheel to increase or decrease the driving depth. Test on a scrap piece of material to achieve the desired depth.

4. Operating the Tool
4.1 Selecting Firing Mode
The NEU MASTER nailer offers two working modes: Single Firing and Contact Firing.
- Single Firing Mode: For precise placement of individual fasteners. Press the safety pole against the workpiece, then pull the trigger.
- Contact Firing Mode (Bump Firing): For rapid fastening. Hold the trigger, then press the safety pole against the workpiece to fire.
Figure 4.1: Illustration of the two firing modes: Single Firing for delicate projects and Bump Firing for large-scale projects.
4.2 Using the Safety Pole
The safety pole is a critical feature designed to prevent accidental firing. The tool will only fire when the safety pole is fully depressed against the workpiece.
Figure 4.2: The safety lock mechanism, which ensures the tool only fires when the safety pole is fully depressed against the work surface, preventing damage and accidental injury.
4.3 LED Work Light
The integrated LED light illuminates the work area, improving visibility in dimly lit conditions. It also serves as a diagnostic indicator (see Troubleshooting section).
