1. Depress the contact trip firmly against the work surface.
2. Pull the trigger.

WARNING: A fastener will be driven each time the
trigger is pulled as long as the contact trip remains
depressed which could result in accidental driving.

The bump action trigger's intended use is for rapid fastening
on flat, stationary surfaces.
Using the bump action trigger, two methods are available:
place actuation and bump actuation.
To Operate the Tool Using the Place Actuation Method
