adjusting clamping
Qty
the correct clamping pressure depends on the
workpiece thickness. the ideal pressure will
have medium/hard resistance but will lock the
workpiece into position easily at the bottom of the
foot pedal stroke—much like a pair of Vice grip.
this pressure is adjusted by evenly turning the
clamping pressure knobs, shown in figure 13,
located on both sides of the pan and box brake.

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, loos-
en the clamping pressure knobs by turning
in even increments and re-clamp until it
locks.
— if the foot pedal locks in place but the
workpiece is not clamped snug, tighten the
clamping pressure.
