Gardner Bender B2000 Series G Cyclone Bender - Manual (Page 3)

6. When bending 1 ⁄
2
" - 1" conduit the upper roller and support
arm must be positioned between the shoe and the roller
housing. Position the urethane roller by moving the roller
housing against the frame stop and removing the pin.
7. Lift the roller support arm to clear the nylon rollers and
swing the arm (toward shoe) over the roller housing.
Lower the arm into the support bracket and insert the ring
pin. See Figure 4.
Figure 4. Position Roller Support
8. Insert the conduit in the shoe groove marked with the
number matching the size conduit being bent. The conduit
must set in the shoe and in the jaw. The end of the conduit
must extend a minimum of 2" beyond the jaw. See Figure
3. Refer to table A or B on page 5 for bending data.
9. Each time a different size and type of conduit is being
bent, three facts must be determined and set into the
bender shoe control system. The required settings are:
conduit size, material and desired bend angle. Prior to
setting, be sure the desired size indicator scale is toward
the operator and the correct shoe grooves are also toward
the operator.
a. Lift the locking handle. See Figure 5. Use the two
small pins to rotate the angle disc, clockwise, until the
red zero line is directly in line with the zero line on the
size scale.
b. Set the bender for specific conduit size by turning the
angle disc until the red line is on the size indicator
mark which matches the size conduit being bent. Be
sure the correct size scale is being used (EMT, lMC,
or Rigid).
c. Move the bend angle set knob (See Figure 5) until the
flat edge of the pointer is on a line indicating the exact
degree of bend desired. Lower the center arm to lock
the pointer and scale and to prevent inadvertent
movement during bending.
Figure 5. Set Angle Scale
10. Activate the bending shoe by holding the pendant control
toggle switch in the “Bend” position. The shoe will rotate
until the angle set on the pointer is reached.
11. To remove the conduit, hold the toggle switch in “Return”.
The shoe will return to the start position and stop
automatically. The zero set light will come on. Bending
more conduit of the same type and size is accomplished
by loading conduit and pressing the toggle switch.

" and 2" Conduit
NOTE: All operations referring to “toward the operator” are
viewed from the lifting handle end of the bender frame.
1. Bending 1 1 ⁄ 4 " through 2" requires using one of the three
sets of nylon rollers and one of the grooves on the lower
half of the bending shoe.
2. Move the roller housing against the frame stop. See
Figure 10. The upper urethane roller must be on the
outside (toward frame handle) of the roller housing. See
Figure 6. If it’s not, pull the ring pin. Lift the roller support
arm, swing it over the roller housing, lower the handle into
the bracket and insert the ring pin.

CAUTION: To avoid damage to the bending shoe,
always place the roller housing against the frame stop,
prior to activating the bending shoe.
