TO ADJUST THE PROXIMITY SWITCHES
For the proximity switches to work properly and
reverse the direction of the carriage at each end of a
traverse, a distance of 3/16 in. +/- 1/32 [4.75 mm +/
- 0.75] must be maintained between the top of the
switch and the actuator bracket on the bottom of the
carriage. See FIG. 33.
To adjust the clearance, loosen one of the switch
mounting nuts while tightening the other.
TO ADJUST THE GIB PLATE
The gib plate must be readjusted occasionally to
eliminate free play. Otherwise the grinding head can
move from side to side, and the bedknife may be
ground unevenly.
The gib must allow the carriage to be cranked freely
forward and back without any side play.
See FIG. 34. To adjust:
1. Crank the carriage all the way forward
(toward the operator position).
2. Tighten the front gib screw until the carriage
has no side play but the horizontal handwheel
can still be cranked.
3. Crank the carrige gradually back (away from
the operator position), and adjust the
remaining gib screws as you go.
