Gardner Bender B2000 Series G-OLD Cyclone Bender User Manual
3 offset bending, 4 stub-up bending, Table a
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 indicator 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.
