The bostitch nailer pictured along along with your question is a RN46 roofing coil nailer. It has a dial on the front of the nose for adjusting depth. Some older nailers (roofing nailers) do no have a means of adjusting so were set at the factory for best performance. The question of depth usually comes up when lower bumper fails and the nail is driven too deep. Easy test. Remove nails and find a very soft piece of wood. Dry fire the gun against soft wood and measure how deep the driver is entering the wood. Harder test. Remove the head and use any handy tool to push driver down to bottom. Measure how far the driver extends past nose (should be about 1/8 to 3/16). If more, replace the lower bumper. Good luck

Usually caused by debris in the small air passage from inside of gun to feeder piston. Easy to check. Remove the head and pull out the cylinder. Debris in the chamber is usually small pieces of oring or the lower bumper is coming apart. This debris will enter passage to feeder which is visible at bottom of chamber. If debris is found, clean chamber, passage, and feeder chamber. Debris will lodge on the oring between the body and nose. Clean and replace parts as needed. If the gun was found to be clean inside, suspect weak or missing feeder spring/s. Good luck/

If you have a very slow leak most likely the lower half of the headvalve (white plastic) is scratched. The gun will work ok but waste air. Parts are not expensive and are available from Dewalt service center. Remove head and pull out headvalve. Look for scratches where oring makes contact. If a lot of air is leaking, most likely cylinder seal needs replacing (vinyl ring installed on the headvalve) or has debris keeping it from making full contact with the cylinder. If you have lots of hours of use you may consider installing the rebuild kit. Good luck.

Remove the nails and take off the trigger to expose the trigger valve (usually part # tva6). Connect air and spray soapy water on the valve to determine if the air is leaking from the center of the valve or around the outer edge between the body and valve. If leaking from the center, could be defective valve or debris under oring. Pop out the valve and examine internal parts for cut oring or defect. If leaking from between body, you could have cut orings installing the valve. Make sure that there are no rough edges in the body of the gun. Bump fire or single fire happens with the trigger type not the valve. Bump fire trigger is usually black metal and single fire trigger is light color plastic. Good luck
