6.3 Adjusting for metal thickness

The hold-down assembly must be adjusted to allow
for clearance when making bends according to
material thickness. Clearance for material within
four gauges of the capacity should be twice the
thickness of the material. For lighter gauges use 1-
1/2 times the thickness.
Turn both knobs (M, Figure 6) the same amount to
maintain parallelism of fingers with apron.

6.4 Adjusting clamping pressure

Clamping pressure should be adjusted according to
material thickness. Clamping pressure should be
great enough to hold material securely in place but
not so much that it is difficult to lock the clamping
handles. Clamping pressure can be adjusted by
turning the nuts on the threaded rod portion of yoke
assembly (P, Figure 7).
When clamping handles are properly set, you will be
able to feel them drop into locking position.

6.5 Repeat bends

Adjust stop collar on stop rod (Figure 4) to limit
apron swing.

7.1 Lubrication

The machine must be lubricated every day of

Figure 7) and the apron assembly near the hinge pin
(B).
