Adjusting Clamping
Pressure
The correct clamping pressure depends on the
workpiece thickness. The ideal pressure will
have medium/hard resistance and will lock the
workpiece into position easily—much like a pair
of vice grips. This pressure is adjusted by moving
the clamping pressure adjusting nuts, shown in
Figure 16, located on both sides of the pan and
box brake.

(one side).
To adjust the clamping pressure:
1.
Lower the bending leaf.
2.
Place the workpiece between the fingers and
the clamping block.
3.
Push the foot pedal down and lock it in
place.
— If the foot pedal will not lock in place,
loosen the clamping pressure evenly until
it will lock.
— If the foot pedal locks in place but the
workpiece is not clamped snug, tighten
the clamping pressure.
