OPERATING INSTRUCTIONS
OFFSET BENDS
1. Determine the height and angle for the desired offset
2. Refer to the rolling shoe starting position chart and use the multipler
calculation to determine the starting arrow position of the rolling shoe.
As an example, for a 45° bend, the multiplier is 1.41. To make a 10" high
offset bend, multiply 10" × 1.41 = 14.1". Place the arrow on the rolling
shoe at the 14.1" mark on the horizontal scale.

3. Using a battery powered drill (recommended drill –
1/2" variable speed cordless drill with a minimum
18 Volts), connect to the hex drive shaft with
the 3/8" hex bit provided. Align the
zero line on the vertical
scale with the vertical scale
indicator (see drawing).
4. With the conduit support
block lowered, the rolling
carriage block closed and
secured and the conduit
hold down open, slide the conduit over the conduit support block and
through the correct groove on the rolling and elevating shoes. (See chart
below for the correct groove size). Continue to slide the conduit past the
elevating shoe until the desired amount of conduit extends past the shoe.
The length of conduit that extends past the edge of the elevating shoe
will be the straight portion of the conduit that extends past the offset.
NOTE: All shoes are marked with a line indicating the center of the bend.

5. Raise the conduit support block. Then close the conduit hold down
and tighten the screw(s) against the conduit. Be sure the conduit is
completely seated in the elevating shoe groove(s).
