Question about Stanley NEW Bostitch 2 HP 6 Gallon Electric Air Compressor

1 Answer

I have a Bostitch CAP2000P-OF 6 gal compressor. When the pressure switch cycles off, the compressor bleeds off air till the pressure switch cycles on then it stops. It repeats this cycle constantly. It will also bleed air if I press the red "off" button. It is not coming from the bleed off valve.

Something is wrong with your "unloader" I should think. That is the device that removes the pressure from the cylinder so the machine does not have to start up against its full air pressure
There will be a narrow air pipe connecting the compressor to the switch assembly which bleeds off the air when the power is off. That hiss you get when you turn it off or it turns itself off.
I think you will find a leak there or possibly the non return valve that stops all the air escaping when the unloader valve is open has failed or got a foreign body stuck in its seating.

Can the pressure switch on a Bostitch pancake compressor model cap2000p-of be adjusted so the compressor will come on and shut off at a different pressure than what was set a the factory?

NO unfortunate There is a electric pressure stop on this model !! not an adjustable pressostat (presure switch) pos 21 is the electric stop at maybe 8 or 10 bar
the savety valve is pos 22 (there is mostly a maximum pressure notition on to read) there is nothing to adjust on this type compressor what is made for a group a (Stanley-Bostitch-Dewalt) patented this pump is placed in several types of compressors of this brands.

I have a Stanley Bostitch CAP2000P-OF Air Compressor. It runs constantly and won't reach the shutoff pressure. It will build some pressure. When I turn it off, I dont hear any leaks.

There is a leak somewhere... Use a soapy solution at the air tube from the compressor head to the tank (both ends) and at all air hose connections. The bubbles will tell you where the leak is and you can repair the connections from there...

I have this compressor and when I pull the switch to turn it on nothing happens. It is only about 5 months old. Is there a reset switch or somthing?

Hi and welcome to FixYa, I am Kelly

The parts schematic can be found on this page:

Pop-ups have to be enabled to see the pdf file schematic that will come up with this address:

I tink your pressure switch has failed that is item 21 of the above link. The SHOULD be a warranty repair. Item 21 : AB-9415626 0021 PRESSURE SWITCH $21.60

It is possible that the motor itself has failed but on a unit 5 months old the pressure switch is the most likely suspect.

The warrnaty Service has an "At your expense shipping" statement.

To obtain warranty service, return the product at your expense together with proof of purchase to a

Bostitch Regional or authorized warranty repair center. You may call us at 1-800-556-6696 for the
location of authorized warranty service centers in your area.

Bostitch, Inc., warrants to the original retail purchaser that this product is free from defects in

material and workmanship, and agrees to repair or replace, at Bostitch's option, any defective
product within 1 year from the date of purchase.

Maybe you live in area where you could do a carry in service.

For sure I would call them.

Thanks for choosing FixYa,

My pressure reducer on my bostitch CAP2000P-OF compressor is broken how do I replace it?

Number 27 is your Regulator. As you see, the housing will have to be taken off, and this will be more involved than many other compressors, due to its compact design, and their choice of pressure switches, causing everything to be built on to the regulator. The part # is AB-9415883
and runs about 10 dollars. Here is a link to a larger diagram.

You can order it from a local service center, and to find them, you type your zip code into
the appropriate box at this link

I hope this helps, let me know if you need anything else.
