Finish Nailer leaker air through the top vent

Conrad - March 28, 2021
Tool Type

Nailer

Difficulty

Medium

Time

30-60 minutes

Tools Used

Screwdriver, Hex wrenches

This nailer is about 17 years old and has seen a lot of use. The last time I used it is work for a couple of trigger pulls and then began leading air through the top vent and stopped driving. I did some research on the repair and then went to the manufactures web site, but they no longer carried any parts. All the parts I needed I got from eReplacment parts.

Disassembly was fairly simple. The piston was stubborn to remove but a sharp rap on a wooden block did the trick. Checked all the parts for damage and found that the spring bumper was broken in several places. Ordered that part and replaced all the seals since the unit was apart. Recommend lubricating each seal and its mating part before reassembly. A good cleaning of the tool is also recommended along with oiling other areas with moving parts. Works great. Recommend about 80-85 psi when operating brad and finish nailers.

Nailer won't fire, only leaked air while the trigger was depressed in the trigger area

Nailer

Difficulty

Easy

Time

30-60 minutes

Tools Used

Socket set, Wrench Set, Dental Pick

Disassembled the trigger and then removed the trigger valve from the body of the gun using a socket. I replaced all of the O-rings in the trigger area and lubricated them with the oil that comes with the gun. I then reassembled the valve and screwed it back into the gun body. I reassembled the trigger making sure that the safety worked as it is designed to. The gun worked properly after the repair and continues to at this point. I am satisfied that the O-rings were the cause of the problem.
