12.6 LIMIT SWITCH ADJUSTMENT
Referring to Figure 19:
Loosen the
jam nut
and set the
adjustment screw
so that
the
limit switch
will actuate to the off position when the saw
has cut through the workpiece.
12.7 COUNTERBALANCE SPRING TENSION
The
counterbalance spring
is located on the rear of the saw
table (refer to Figure 20). The counterbalance spring is used
to adjust the amount of down force the saw arm puts on the
workpiece when the hydraulic control cylinder is fully open.
If adjustment is needed:
1. Raise the saw arm to its full upright position and lock
it in position.
2. Set the spring tension by adjusting the nut until 1-1/4
to 1-1/2 inches are exposed on the right side of the
eyebolt mount.
The saw can now be returned to service.
