How do I adjust the depth of drive for an F350 Framing nailer?

Do not attempt to operate or service the nailer until you have read and understood all safety precautions and manual instructions. Disconnect the air and remove fasteners from the nailer when making any adjustments or servicing it. The F350 Framing nailer has a 3/16 hex key located in the rear of the magazine. To adjust the depth of the nail, loosen the bolt on the work contacting element with the hex key. Raise the work contact up to drive the nail deeper or lower the work contact to drive the nail more flush. Tighten the bolt on the work contact and test the tool.
