To adjust the fingers:
1. Loosen the cap screws on the fingers, then
push the fingers up into the hold down
assembly stop.
2. Making sure the fingers are held square and
tight to the hold down assembly stop (
Figure
2), then tighten the cap screws to secure
fingers.
To adjust for metal thickness:
1. Loosen the setscrews on the back of both
sides of the hold down assembly.
2. Rotate the eccentric on the back of the hold
down assembly. The hold down assembly will
move in and out, moving the front of the fin-
gers toward or away from the apron face
3. When the fingers are adjusted to the proper
offset and are parallel to the apron face and
base, tighten the set screw to secure the
eccentric. Note—The offset between the front
edge of the finger and the face of the apron
needs to be approximately 1
1
⁄
2
times the
thickness of the material being bent or great-
er. It cannot be less than 1
1
⁄
2
times or dam-
age will occur to the finger knife edge.
4. Loosen the two turnbuckle hex nuts on each
side of the hold down assembly (

5. Adjust the hold down assembly for the metal
thickness, using the turnbuckle on each side
of the hold down assembly. The holding pres-
sure should be great enough to hold the
metal from moving when bending, but not so
tight that the hold down handle is hard to
operate.
6. When the desired tension is reached, tighten
hex nuts on each side of the hold down
assembly.
