Bending Conduit
1. Use the hydraulic pump to advance the ram until
the shoe contacts the conduit. Apply slight pressure
to the ram. 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. Refer to the “Bending
Instructions” section of this manual for marking the
conduit for the necessary bend.
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 for Common Bends”
to nd 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.
To use this table, nd the size of the conduit
to be bent in the left column, and nd the
desired angle of bend in the second row. The
intersection of the appropriate column and
row shows the approximate amount of ram
travel necessary to ac com plish the desired
angle of bend.
