6.1 Selecting Trigger Mode

The NR83A5(S) features a selectable trigger, allowing you to choose between two firing modes:

• Sequential Actuation Mode: The trigger must be pressed and the contact trip depressed against the workpiece in sequence for each nail. This mode offers precise nail placement.
• Contact Actuation Mode: The tool will fire a nail each time the contact trip is depressed against the workpiece while the trigger is held down. This mode allows for rapid firing.
