6. If one or more of the other corners does not match the upper left corner, loosen the lock nut and
adjust the caster directly underneath that corner up or down until the focus tool fit at that corner
matches the fit at the upper left corner. First loosen the lock nut (1), then turn the adjusting screw
(2) in 1/8 turns. Once the foot is at the correct height, tighten the lock nut (1). When you are done,
the focus tool fit at all four corners should be the same.
*Alternate leveling method
For the best leveling results, use a digital caliper and adjust the caster directly under each corner
that does not match the height of the upper left corner until that corner matches the upper left
corner’s height. Verify that you zero out the caliper before taking any measurements. The height at
each corner should be within 0.010” (0.254 mm) of the height at the upper left corner.
