Leveling appliances can be tricky business, but one simple tool can change that. Get yourself an Air Shim from Calculated Industries. They can be used in a wide range of applications, and they make leveling appliances much simpler. Just slide the little black bag near whatever part of the machine needs adjusting and start pumping air into it. Then, place a level on top of the appliance and watch for the bubble to hit the center. All that’s left is to adjust the appliance’s leg to that height and let the air out of the shim.
