Why is my nail gun blowing air out the back?

If you try to fire a pneumatic nail gun or stapler, but only hear air leaking when engaging the trigger, it’s likely that your tool’s “O-Ring” is not sealing properly. Simply stretch the “O-Ring” on the firing valve and apply grease. This should take care of the issue – helping your air tool run properly.

Why is my Porter Cable nail gun leaking air?

Nail guns require more frequent maintenance than other power tools. These forces can wear down the o-rings in the gun, causing them to leak air. You will need to install an overhaul kit in your nail gun if it is leaking from the nose, head or trigger.

Why is my nail gun not firing?

Jams are typically caused when nails feed incorrectly and wedge against the driver blade, preventing the tool from cycling. Jams are the most common cause of a nailer not firing. For safety, first disconnect the tool from the air supply, retract the feeder mechanism, and remove any excess fasteners from the magazine.

Do nail guns wear out?

Pneumatic nailers are powerful workhorses and handle long hours of work. Over time, the continual use of the parts can begin to wear or become damaged.

Why is my nail gun double firing?

Many nail guns have a recoil, or pushback once the nail is fired. When this happens, a contact firing nailer is more likely to “double fire,” sending two fasteners out of the tool before the trigger is released. The danger, of course, is that the fastener ricochets or shoots elsewhere than the intended surface.

How does an air nailer trigger work?

Before the trigger is pulled, the air pressure below the piston is greater than the air pressure above it, which keeps the piston at the top of the cylinder. When the trigger of the nailer is depressed, the valve opens, forcing air into the cylinder and making the pressure above the piston greater than below it.

How long does a nail gun last?

A battery for a cordless tool will last approximately 3 years or 1,000 charge cycles. For gas-powered nailers, expect to pay about $13 to $15 for a single fuel cell. While fuel cell life can differ depending upon size and application of the tool, most deliver 1,000 to 1,300 shots.

Why is my Dewalt nail gun not shooting nails?

Clear out any jams in your Dewalt nail gun. Remove the battery and the magazine and make sure there are no fasteners causing a jam in the mechanism. If you see a jammed fastener, remove it and manually push the driver blade back up. Reinsert the battery and magazine.
