Review on Milton S 506 Original Chuck Inflator by Jessie Ritchie

First off, this is a really good pump. It's explosion-proof, you can buy parts for it, and it's ADJUSTABLE so you can set it to the pressure range you want. I use mine primarily for car tires and my weight is around 8 lbs. That's fine for 90psi truck tires, but that's not what I bought it for.

Remove the large screw at the end of the cartridge and use a small screwdriver to adjust the gauge. 1/2 turn = approximately 5 psi at the bottom (30-40 psi) end of the scale. A bit of trial and error with a pressure gauge you trust at the pressure you're measuring. and you did To save yourself a cycle of disassembly and reassembly, be sure to insert the cartridge with the gauge facing the sight hole.
