Adjustment of the upper blade provides a simple method
of compensating normal deflection and errors in blade
grinding without the use of shims. Easily accessible
screws permit one man to make the adjustment in
minimum time.
SPRING COUNTERBALANCES
These support the weight of the ram, ram back brace and
back gauge assembly.
The counterbalances exert a
backward and upward force to maintain -maximum ram and
slide bearing contact, preventing improper blade clearance
or blade damage caused by "floating" of the ram. Spring
counterbalances are furnished on 0200, 0300 and 0400
series.
