Operating Instructions

Bending
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. See the illustration under
"Ram Travel Table for Common Bends."
2. Use the hydraulic pump and advance the ram until
the shoe contacts the conduit and the conduit is
seated in the follow bar. Check the placement of the
conduit to be sure that the bending mark is aligned
with the outside edge of the saddle.
Note: For specific pump operating instructions, see
the instruction manual supplied with the hydraulic
pump.
3. Consult the "Ram Travel Table" to find the amount
of ram travel necessary to accomplish the bend.
4. Use the hydraulic pump to advance the ram by the
necessary amount of ram travel.
5. 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; the second
bend angle is twice the number of degrees and
requires more ram travel than the first and third
bends. If making a 4-bend saddle, rotate the conduit
before making the second and fourth bends.
6. Repeat steps 2–5 until the last bend is made.
7. Release the hydraulic pressure at the pump.
Remove the locking hitch pin to release the upper
connecting plate. Lift the plate clear of the shoe,
follow bar, and saddle.
8. Remove the conduit from the bender.
