Here is the excerpt from one of my nail gun manuals. This happens to be a Hitachi full headed framing nailer, but all them work the same [Senco,Bostich,Pasload...]

(2) Continuous operation (push lever fire)

a) Pull the trigger with the Nailer off the workpiece

b)Depress the push lever against the workpiece to drive the nail [Push the nose down]

c)Move the nailer along the workpiece with a bouncing motion. Each depression of the puch lever will drive a nail.

A soon as the desired number of nails have been driven, remove the finger from the trigger.

FWIW, I can recall several occasions when operating pneumatic nailers in tight spaces like joist bays or closets or the like, where I could barely fit the gun into the cavity, and upon firing the first shot, the subsequent bounce recoil bounce back turn the damn thing into tommy gun as it tried to empty its clips.

This guy could have got pinned against the scaffold, or the building, or under the guy after the fall, producing the same effect.

I could have an easier time believing this was an accident if he got shot once or twice, but six times from two different angles?

Secondly, imagine walking a wall with a framing nailer in your hand. Something, anything, causes you to fall. Your first instinct will be to drop the gun and reach for whatever you can.

That's what I did when a gust of wind knocked over the trusses we were standing on a Hardees in Tampa. Fla., knocking me off the wall.
