The gib controls the smoothness of the slide
movement, as well as the run out or end play
of the spindle. Tightening the gibs too much will
make it hard to adjust the height of the spindle
and cause excessive wear on the slide. Loosening
the gibs too much will introduce spindle end play
and cause poor cutting results and excessive
wear on the spindle bearings.

Gib Adjustment

DISCONNECT MACHINE FROM POWER!
Use the spindle height handwheel to raise the
spindle to its highest position.
— If it is difficult to turn the handwheel or you
feel resistance from the spindle slide, the
gibs may need to be loosened.
Use the spindle height lock to hold the spin-
dle in place, then attempt to wiggle the top
of the spindle. If there is movement, the gibs
may need to be tightened.
