Blown PC Nailers4/16
Can anyone suggest why these two guns blew out within three days of each other? Pressure at 100 lbs. Different size nails. One happened during a misfire.
They look well used.
Might you have had a spike in air pressure? Do you have a blow off valve that limits the top pressure?
We use Senco SLP20 and Omer micro pinners, bullet proof.
Are these oil or oil-less, hydraulic pressure is far more powerful than just air. Who is putting the few drops in them in the morning?
Brad nailers,staplers, pinners should all be run 60-80 psi. Typically 65psi.
We hardly ever oil our guns. We have Hitachi trim guns that are 20years old which have done many mansions worth of nailing with a little drop of oil once a week in full use. We donít want oil all over the trim. They arenít framing guns.
I owned one of the PC pinners for years. The driver pin started leaving dents so we switched to Greg. I still own a PC 18 gauge stapler from the mid 2000ís that has fastened every cabinet back weíve done.
The older PC guns were quite good.
Both of them, 18 ga, were about 15 years old, and nothing lasts forever, but it was curious that they both blew a couple of days apart.
But I was noticing yesterday that the Dewalt pancake compressor that was serving them, surges; the air pressure is not even. So I think that was the cause.
I oil minimally, depending on the use. I had trouble with my Grex and Cadex pinners several years ago and learned that a drop a day is too much. No problems since I reduced.
Must be common to these models.
They're old. They're worth 100.00. They don't owe you anything. Just get a new one.
