Pneumatic Nail Guns

The most popular sort of nail gun is the pneumatic nailer. In these machin­es, the hammering force comes from compressed air, typically generated by a separate air compressor. A pneumatic nailer uses the same sort of hammer as a solenoid nailer: It has a sliding piston that drives a long blade. When the air pressure above the piston head is greater than below it, the piston is forced downward. When the air pressure below the piston is greater than above it, the piston stays up. The trigger mechanism serves to channel the flow of compressed air to shift this balance.

Some nail guns can launch nails at 1,400 feet per second.

Pneumatic nail guns work very well, even at driving thick nails through hard material.

Each gun is specifically designed to accept and use specific thickness and lengths of nails

Here's what happens when you pull the trigger on a pneumatic nail gun:

1. The trigger valve closes and opens a passageway to the atmosphere. With the trigger valve in this position, the compressed air can't flow to the area above the valve plunger.

2. There is greater pressure below the plunger than above it. The plunger rises up, and the compressed air makes its way to the piston head.

3. The compressed air drives the piston and the blade downward, propelling the nail out of the chamber.

4. As the piston slides downward, it drives the air inside the cylinder through a series of holes, into a return air chamber (f).

As more air is pushed into the chamber, the pressure level rises. When you release the trigger, compressed air pushes the plunger back into place, blocking the air flow to the piston head. With no downward pressure, the compressed air in the return air chamber can push the piston head back up. The air above the piston head is forced out of the gun, into the atmosphere.

OSHA recommends:

• Follow all manufacturer’s instructions when using a nail gun.

• Ensure the tool meets all applicable OSHA guarding standards.

• Wear safety glasses that provide a side shield.

• Never attempt to modify or circumvent a safety feature.

• Keep your fingers away from the trigger when not driving nails.

• Consider using a sequential gun that requires both the trigger and the nose of the gun to be depressed before firing.

• Always disconnect the gun before performing maintenance, moving to another work area or clearing jams.

• Position yourself and your free hand out of the line of fire, and watch out for co-workers behind the nailing surface. Never point a nail gun at someone.
