Check to see if the jacks are just slow but physically able to return without adding a lot of sloppy lost motion. Pinning, lubrication, may be required.</div> <div class="Section1">2. Are the jacks binding when the keys are "bottoming out"?

Don't alter the checking unless you know that is the problem or they are not checking correctly now.
