Bending Conduit
1. Loosen the ram travel scale nut; set the ram travel
scale, which is read at the edge of the block, to zero.
Tighten the nut.
2. Mark the conduit. See the instructions for marking the
conduit for the necessary bend in this manual.
3. Insert the conduit into the bender. Align the bending
mark on the conduit with the center of the bending
shoe.
4. Consult the Ram Travel Table to find the amount of
ram travel necessary to accomplish the bend.
5. Use the hydraulic pump to advance the ram by the
amount of ram travel found in Step 4.
6. Release the hydraulic pressure at the pump and move
the conduit to the next bending position.
Note: If making an offset bend, rotate the conduit 180˚
before making the second bend. If making a
three-bend saddle, rotate the conduit 180˚ before
making the second and third bends. If making a
four-bend saddle, rotate the conduit 180˚ before
making the second and fourth bends.
7. Repeat Steps 5 and 6 until the last bend is made.
8. Remove the conduit from the bender.

FIGURES ARE APPROXIMATE
Note: To use this table, find the size of the conduit
to be bent in the leftmost column and find the
desired angle of bend in the top row. The inter-
section of the appropriate column and row shows
the approximate amount of ram travel necessary
to accomplish the desired angle of bend.
