My TS056CK staple gun releases a small amount of air pressure. Compressor is set at 90 psi and the brad gun works fine. Any ideas?

SOURCE: Air Compressor, low pressure

does the compressor keep running all the time but never gets above 40 or does it turn off at 40?
if it is turning off at 40 I would try using another gauge just to be sure it is 40psi, and if that is the case then you probably have a faulty pressure switch, if the compressor is constantly runnign but won't get past the 40psi then you may have a worn out compressor, check the oil for either a low level or if the oil is dirty, if it is you may just need to drain and refill but if that doesn't fix the issue then you will need to rebuild the compressor

Take head off of tool. Clean and lube orings on the head valve . Do not use wd40 use air nailer oil.

Hello. I can help you. The nail gun you have uses 18 gauge brads. I would use only original Bostitch 18 gauge.

The one MM of difference you mention is the reason why you do not have the pressure you did have. Get rid of those 31MM brads and get the 18 gauge. Home Depot carries the Bostitch line. I would go there or to homedepot.com

SOURCE: How do you load brads into the Arrow t50pbn staple gun?

Yes, the gun comes with no instructions. Strange but thanks, there is Internet. DO NOT PUSH THE TRIGGER during any time of this process. BE SAFE and use your common sense. If you don't know what you are doing, stop right now and see help from someone who knows more.

1. Turn the gun upside down so the bottom of the gun is upwards. let's suppose the end through which the stapes come out are on the left side and a little spring push tab is on the right side when the gun is in this position.
2. Push the spring tab in and you will see a little catch disengage from a notch (the notch is located just above this push tab).
3. While keeping the tab pushed in, pull the tab up until the catch that disengaged from the notch (see step, above) comes clear of the notched area of the gun.
4. The spring loaded bar / arm will pop /slide out now.
5. Load the staples into the staples housing / channel (make sure the open end of the staples is upwards (remember, the gun is upside down and the bottom of the gun is facing up)).
6. Slide the spring arm back in. Push it in a bit and let the catch in the push tab pop back into the notch.
