My bostitch pancake compressor - only getting to 100psi


i have the dial up all the way its supossed to get 135psi but its only getting to 100psi any reasons why or something i can do

Hi John.

What is happening to the compressor when the pressure gets to 100 PSI? Is it stopping, or running on but not building more pressure?

We can start to figure out why by you having a read of the pages about why an air compressor will not build pressure properly, linked from the troubleshooting section on the site map page.

Have a look, and post an update here about what you found, and we'll press on, OK?

Cheers,

Bill

Bostich Compressor never gets to cut off pressure?

by Shawn
(Denver)

I just replace the valve head with a newer style head from the CAP60PB-OF (mine is the CAP60P-OF) due to a broken valve flap. Now it gets to about 128lbs and stops building pressure but keeps running. The piston ring appeared to not have excessive wear.

Sounds as though you might have a gasket issue, Shawn.

Did you replace the gaskets when you replaced the valve plate? If not, you likely need to. If so, you may have a crimp or weakened area that lets go when the pressure gets to the 128 PSI, and then the air just cycles back and forth in the head.

Cheers,

Bill

Bostitch 2040 Wont build pressure past 80 psi?

by Paul
(BC, Canada)

The compressor just keeps going, does not make 135psi, there are no leaks, what can I look at next?

Hey Paul.

When you read the various tips about why air compressors stop building air pressure (troubleshooting section on the site map page) what have you checked so far, please?

It's often one of only two or three things that can cause this, all are noted on the pages of this site, and knowing what you have already found makes me helping you easier.

Why not check them out, and then, give me your answer(s) as a comment here, so that we can try to figure out what is happening (or not happening) with your air compressor?

Cheers,

Bill

Compressor will not turn off?

by Jeff
(Newmarket, Ontario, Canada)

My Bostich 150 psi oil free air compressor will not turn off it kicks the on switch back on

When it builds up pressure my Bostich 150 psi oil free air compressor will not allow me to shut off the compressor without plugging it out.

Worse than this the knob which allows me to control the amount of pressure released to sink nails deeper, will not stay it seems as if it is stripped.

What can I do to resolve these problems

Hi Jeff. Are you saying that your air compressor starts, builds pressure in the tank, the air pressure in the tank passes the normal cut out pressure, and the compressor keeps running? If that is the case, does the compressor blow off the PRV?

When you set the downstream air pressure level with the regulator, are you saying that, if for example you had set the pressure at 80 PSI for the nailer, that the pressure gauge on the regulator shows a higher pressure?

Please provide a bit more info in a comment here so I can follow the thread.

Cheers,

Bill

kicks switch back on
by: Jeff

Hi Bill the pressure builds to 120 psi and then stops. While it is filling if I try to push the off switch the compressor kicks it back on.

The knob that controls the pressure I can fire a nail at seems to be stripped.

So, the cut out pressure is 120 PSI, and the compressor will stop at that pressure? If you turn the switch off before the pressure reaches that 120 PSI, and the switch pops back on, I suspect the switch is pooched. However, to ease the maintenance issue, let the compressor reach 120 PSI and stop automatically, or pull the plug when you've had enough. Either that, or get the switch checked out.

You didn't answer me about the reading on the regulator gauge. If the knob is stripped from the inside (this is possible) it's time for a new regulator. Try pushing the knob in or pull it out and see if it connects that way. Some regulators are built so that the knob can be disconnected internally by pulling or pushing the knob. If that doesn't do anything, and you cannot adjust the downstream pressure, time for a new regulator.
