10. To bend more conduit of the same material and at the

same angle, load and secure as described in steps 3
through 6. To bend the same type conduit but at a different
angle, load and secure; turn angle set knob to the desired
angle, then press toggle to bend.

11. Bending different type and size conduit requires repeating

steps 2 through 10.

4.3 Offset Bending

1.

Obtain distance “M” from table A, and measure this
distance from mark #1 and place mark #2.

2.

Now place mark #1 in line with front edge of shoe clamp
and make first bend.

3.

Next rotate conduit 180° level, place mark #2 in line with
front edge of shoe clamp and make second bend.

NOTE: When bending rigid aluminum, set bend angle indicator
approximately 4° short of desired angle, since aluminum does
not have spring-back of steel.

4.4 Stub-up Bending

1.

Table C shows minimum length (inches).

2.

Mark #1 is stub length, deduct from this as per table C
and obtain mark #2.

To locate distance between centers of offset bending marks other than listed in
table A use the following multipliers:

15° bend - 3.9
30° bend - 2.0
45° bend - 1.4
