90˚ Bends
4. For first bend, measure from end of tube
and mark at blueprint dimension. (Figure 3)
5. Raise Latch. Bring handles together to
release Drive Arm. Swing Drive Arm counter
clockwise until it stops. Move Swinging Arm to
clear opening between Form Handle & Roll.
6. Position tube in bender. (Figure 4a) If the
end from which you measured is in the Form
Handle, the measured mark should be
directly under the 90˚ mark on the Drive
Arm. (Figure 4a) If, however, the end from
which you measured is to the right (Not in
the Form Handle), set the mark on the tube
directly under the "R" on the Drive Arm.
(Figure 4b)
7. Close Latch over tube and Swinging Arm
over Roll Shaft.
8. To Ratchet - Pull Ratchet Handle away from
Form Handle. After each pull, Drive Arm will
remain locked due to the Holding pawl.
Actuate Ratchet Handle until pointer on
Swinging Arm is at 90˚. Because tubing has
a slight springback action, it may be neces-
sary to over bend slightly to allow tube to
spring back to 90˚.
9. To release Bender, follow Step 5.
10. If more than one bend is required, measure
from center line of the preceding bent leg
and mark tube to blueprint dimension (See
Figure 5) . Position tube in bender as out-
lined in Step 6.
11. For convenience, the Form Handle Clamping
Pad may be held in a vise.
45˚ Bends
12. For first bend, measure from end of tube
and mark at blueprint dimension.
13. Position tube in bender, as illustrated in
Figure 4 a-b . When making a 45˚ bend, the
end from which you measured and marked
the tube may be either in the Form Handle
or to the right (Not in the Form Handle). In
either case, the mark on the tube should be
under the 45˚ mark on the Drive Arm.
14. Close Latch over tube. Move Swinging Arm
to engage Roll Shaft.
15. To Bend - Follow Step 8 until pointer on
Swinging Arm is at 45˚.
