The gibs control the accuracy of the sliding parts
and keep them stable during operation. The goal
of adjusting the gibs is to remove unnecessary
play when the slides are moved, without tighten-
ing them so much that they bind. Each gib can
be tightened or loosened by using the adjustment
screws.
To adjust the gibs:
1.
Loosen the hex nuts on the set screws.
2.
Evenly adjust the setscrews while moving the
sliding part until you feel a slight amount of
resistance.
3.
Tighten the hex nuts against the casting while
holding the setscrews in place so they do not
move when the hex nut is tightened.
