Operating
1. General Operation
To operate the nailer, ensure a charged battery is installed and nails are loaded. Press the contact trip firmly against the workpiece surface. Then, pull the trigger to drive a nail. The tool is designed for sequential firing, meaning the contact trip must be pressed against the surface before the trigger can be pulled for each nail.
