This comperssor is oiless thus has a vinyl piston ring that wears quite fast depending on use and conditions at the work site. Slow pressure build or cycle never completes indicates a worn cylinder and piston ring. I would replace the cylinder, piston ring, valve plate, and intake valve. These parts are not expensive and available at www.bostitch.com. enjoy

Why will my bostitch pancake compressor 240 psi tank 180 regulator that the guages will not show building pressure


Hi, There are different posibilities. I would need more information. Was it always like that? Does the guage on the main tank and the guage on the regulator both not show more than 20psi? When the auto shut-off is triggered do you feel there is more than 20 psi in the tank?

Stanley Bostitch compressor cpack model runs and runs but won't fill tank.


check for any air leaks and fix as needed. then look for oil coming from cylinder heads , if oil is coming from heads you have blown head gaskets ,it wont build pressure like this. you might also check the pop off valve to be blown open. push the pin in and see if air starts to build up then. If so get a new valve.also check the drain valve under the tank and make sure its closed.

Hi have a cosmo air compressor that will only build up 25 lbs of pressure instead of 12olbs?


If the compressor is older or had a lot of use the rings might be worn. Try a compression test on the cylinder to see if there is bypass in the rings.Try this onlt if it keeps running and doesn't build pressure. If it builds up and stops at 25 lbs. the problem is different it would be in the pressure switch. You can then try to increase the the shut off pressure in the switch by turning up the adjustment screw. if this doesn't work I would then change the presure switch for a new one.

My guess is the pressure switch is stuck. Unplug it take the cover off where you turn it on and tap around the contactors lightly with a screwdriver. Then plug it back in and try it.

My compressor won't build pressure over 90lbs


Small leak will prevent the unit from building proper pressure. Check all connections with soapy water and repair as needed (including under cover). If no leaks are found check cylinder for scratches. Push piston to top of stroke and check walls for fine scratches. If scratched, pressure is leaking past vinyl piston ring. If no scratches or leaks, most likely reed valves, head gasket or combination of both. Easy test, with compressor running and attained 90 lbs, place finger over air intake and check for good suction (carefull could be hot) . If good suction, then air is leaking somewhere, of no suction suspect reed valves/worn cylinder, if air seems to be blowing out of intake, suspect reeds /gaskets. Good holidays

I Have a 5.5.hp oilfree air compressor that builds air up to 45 lbs an stops building pressure and keeps run.will not shut off


Is you air regulator working? I suspect your reed valves in the head need replacing as they may not be holding pressure over the 45psi that you mentioned, and are allowing the air pressure to defeat them which allows the psi over 45 psi to bleed back into the air compressor cylinder.

WILL NOT BUILD UP AIR PRESSURE PAST 20 LBS.


Check to see if air is leaking past 'pressure relief' valve. It's probably leaking and that's where all the air is going.

Husky comp on 1st start builds up 75 lbs and wont restart


Check the reset button on the motor to see if it tripped. The motor may be overheating. Some motors have an internal breaker and they have to cool off before they restart. Also check the pressure switch. Move the switch back and forth ( on and off ) and listen for a click. If it doesn't click with low to no air pressure then the switch is bad.
