would not allow air in to nailer
After installing the parts from Fix.com I applied some 3 in 1 oil into the area where the piston is and also where your air nozzle connects. the more oil the better, hook up the air hose and good to go. You tube has many videos for helping as well.

Combination Brad Nailer/Stapler would not operate
The plastic head valve inside the gun disintegrated. Common problem with old guns. Remove 4 screws (part1) with hex wrench and pull off back cap on gun. Try not to damage gasket (part3). Clean out all debris left by old head valve, If you can still use the o-ring from the head valve keep it. The original o-ring is not available buy I orde red a 33mmx2mm online and it works fine. Install per diagram using Vaseline or 3 in one oil on o-rings and cylinders. Make sure to put the flat face of the seal (part5) facing the back of the gun against the metal seal (part4), or it will leak air. Work the new head valve/seal inside the cylinder at the back of the cap to make sure that it compresses inside when it is tightened against the interior spring (part6). Re-Install 4 screws tightening opposite sides gradually so that head valve compresses into cylinder when tight. Should be good to go.
