Title: read the breakin directions
Review: after you read the directions follow the break in procedure. add the oil before you fire it up. open the tank drain and run it for 20 mins with the tank drain open to break it in. then close the drain. after i used it to inflate some tires on various pieces of equipment i shot 25 or so narrow crown staples into some oak, no problems ( at 100lbs on the regulator. always check your equipment for the proper pressure). then to check the presure gauges i left the tanks fill. tank gauge read 155 lbs. regulator 145. i'm not sure why there is a difference, but the regulator control when it seem to be turned all the way to where it's tight, can still be rotated which i did until i reached 145lbs at the regulator. however, i stopped at 145lbs so that i didn't break it. hope this is helpful.
