Greenlee 854 Instruction Manual page 9

Operation (cont'd)
1. Mark the conduit.
• The decals on the bender and the Bending
Instructions section of this manual provide basic
instructions for marking and bending the conduit.
They are based on measurements with common
fractions for accurate results.
• For a higher level of precision, see the Special
Bending Information section of this manual. This
section is based on measurements carried out to
two decimal places.
2. Turn the power switch/circuit breaker to ON.
3. Use the shoe selection switch on the side of
the bender to select the proper shoe (1/2" to
1-1/4" shoe or 1-1/2" to 2" shoe). Press BEND or
UNLOAD until the pointer of the selected shoe is 5°
to 10° before the 0° starting point.
4. Insert the conduit into the proper shoe groove and
hook (green hooks indicate IMC, rigid, and sched-
ule 40 pipe; silver hooks indicate EMT). Load the
conduit so that the bending mark is aligned with the
front edge of the shoe hook.
• If bending 1/2" to 1-1/4" conduit, use the roller
support unit as explained under Operation.
• If bending 1-1/2" to 2" EMT, IMC or rigid
aluminum, use the roller support unit and set
the squeeze as explained under Operation.
• If bending 1-1/2" to 2" rigid steel conduit or
schedule 40 pipe, ensure that the roller support
unit is in the lowered position.
5. See the instruction decal or the Scale Reading Table
for the appropriate bend angle.
6. Bend the conduit:
a. Press and hold BEND.
b. Release the BEND switch as you approach the
desired angle of bend.
c. Press BEND momentarily until the bend is
complete.
7. Unload the bender.
a. Press UNLOAD. The shoe will rotate back and
drop the 1-1/2" to 2" roller support unit, if it was
used.
b. After the shoe has rotated backward 15° to 20°,
release the switch.
c. After the shoe stops completely, twist the
conduit to release it from the hook.
Remove the conduit.
d. Press and hold UNLOAD until the shoe has
rotated back to 0°.

USING ROLLER SUPPORT UNITS
Use the roller support units to squeeze the conduit as it
is bent.
Using the 1/2" to 1-1/4" Roller Support Unit
Pivot this roller support upward and into place when
bending all types of 1/2" to 1-1/4" conduit. Pivot the
roller support down for easier loading and unloading.
Using the 1-1/2" to 2" Roller Support Unit
Engage this roller support when bending 1-1/2" to 2"
EMT, IMC, and rigid aluminum conduit:
1. Position the shoe at the load point shown on the
bend angle chart, approximately 10° before 0°.
2. Insert the tube into the hook system and position
the conduit into the shoe groove.
3. Pull the roller support into the bend start position.
The retaining roller on the 1-1/2" rear roller
assembly will be held by the roller retaining cam.
4. The tube will have freedom to move to allow
positioning of the bending mark.
5. Press BEND until the desired bend angle is
achieved.
Notes:
• If it is difficult to engage the rollers completely, the
squeeze is probably set too high. See Adjusting the
Squeeze in this section of the manual.
• When the roller support is raised, the bender will travel
a maximum of approximately 105°.
• Do not allow a bend or coupler to go over the roller
supports.
• Do not allow the trailing end of the conduit to go
over the roller supports.
Failure to observe these precautions may result in
damage to the bender.
