Porter Cable BN200 will not retract

[cbgav]

Brad nail driver assembly will not retract most times. Have disassembled, inspected and lubricated many times, same problem. Can you suggest O Ring(s) most likely to cause this problem?
Does the "service kit" include these parts?
thanks

Hey cbgav,
The overhaul kit should remedy your problem...part # 60079..it has all the o-rings you will need..[sometimes the valve piston also will need replaced..part # 883832..]
parts avail at ereplacementparts.com..
hope this helps..

My BN200 was doing the same thing. The seal, ref #104, in the cap that the spring, ref # 105, goes against deteriorates and causes the piston, ref # 107 to not work properly. Replace the seal and it should fix the problem.

My BN200V12 just broke on me. The compressor hums and hums but does not shut off and none of the lights light up- no green, no red. Nada. Anybody have a clue as to what the problem might be?
