9.4 Spindle travel range
If “overstroke” occurs in the spindle upper or lower
position (i.e. spindle continues to travel too far after
reaching its limit), adjust as follows:
1. The adjustment area is on back of head,
opposite the auxiliary dial. Move head to the
far right end of rail for access.
2. Move spindle to its upper position. There
should be 3 to 5mm (1/8” to 3/16”) clearance.
3. The cam should be sufficiently contacting the
limiter, as shown in Figure 9-5. If it does not,
Loosen set screw on cam (L) and rotate cam
so that it contacts the limiter, as shown in
Figure 9-5.
4. If needed, loosen screw (N) and adjust limit
device for proper contact with cam.
5. Tighten cam set screw (L).
6. Move spindle to lowest position and slowly
allow cam to touch limit switch until you hear a
“click”.
7. Tighten screw (N).
