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.
7.0 User-maintenance
7.1 Lubrication
The machine must be lubricated every day of
service with a few drops of oil at the pivot points. Oil
fittings are located at both yoke assemblies (A,
Figure 7) and the apron assembly near the hinge pin
(B).
Lightly oil all machined (unpainted) parts when not
in use, to inhibit rust.
