Porter Cable pneumatic finish nailer

[sbhayden1]

My 16 ga FN 250b nailer will only cycle every 6 or 8 attempts and then only when held vertically. I have replaced the maintenance kit of bumper, driver, gasket,handling all parts carefully and making sure they were all lubed well. I carefully torqued all bolts sequentially. Pulling the trigger usually gives only a tiny spurt of air and nothing else. Any counsel?

Your trigger assembly might be your next unit of choice to change,sometimes the seal in the unit goes slack,additionally,there's a particular position the unit is suppose to be facing and that might be the prob.

hope this helps

Another suggestion,have you verified the pressure comming from your compressor to the rear of the nailer? should take a look at that if you have not.

Thanks for the counsel.I'll check the trigger because the air pressure operated other air tools just fine.
