I have an 11 gallon 135psi compressor (Sanborn) and it kicks off when the tank reaches ~110psi. I can set the outflow pressure through the regulator only up to the highest pressure of ~110psi, however I can’t figure out how to get the tank to build to 135psi as it should?
This doesn’t let me use some of my air tools/space hammer and causes the compressor to kick on more often than it should.
and remove the plastic cover surrounding the relay (where the power cord comes out) under that cover you will see a relay, you should also see an adjustment screw with a spring around it, this is the adjustment for the relay armature. screw it in to increase the kick off pressure…
BE VERY CAREFULL TO ONLY TURN IT ONE TURN AT A TIME, then fire up the compressor to see where it stops.
BE VERY, VERY CAREFULL NOT TO EXCEED THE TANK’S PRESSURE SPECIFICATIONS!!!!! IT COULD RESULT IN SEROIUS INJURY OR DAMAGE TO THE COMPRESSOR!!!
when setting a compressor to the max operating pressure, al;ways verify the tank pressure with a known accurate pressure gage. the one on the compressor may be off by as much as 5 pounds and you could be acutally setting the pressure too high if the gauge is off on the low side of actual pressure. i have never had a problem with air tools with 110 pounds pressure. most air tools require 85-100 pounds.
