6. Operating Instructions
6.1 General Operation
- With the air supply connected and nails loaded, position the muzzle of the nail gun firmly against the workpiece. The safety switch lock will disengage when pressed against the surface.
- Squeeze the trigger to drive a nail.
- Release the trigger and lift the tool from the workpiece.
6.2 Extended Muzzle Feature
The ST64L features a 4-inch slim extended muzzle, allowing access to tight spaces and deeper installations that standard nail guns cannot reach. This is particularly useful for tasks like cable raceway installation or furring strip installation in confined areas.
6.3 Safety Switch Lock
The integrated safety switch lock mechanism prevents accidental firing. The tool will only operate when the muzzle is pressed firmly against the work surface, enabling the trigger. When not pressed against a surface, the tool is disabled, enhancing user safety.
6.4 Visual Nail Window
The magazine features a transparent pusher and a visual window, allowing you to easily monitor the remaining nail supply and prevent dry firing.
