Operation - Greenlee 555 Series Instruction Manual

Operation

Always use safety glasses. Everyday
glasses only have impact resistant
lenses; they are NOT safety glasses.
When using in dusty environment, use
face or dust mask.
Failure to wear eye protection could
result in serious eye injury from flying
debris.
Pinch points:
• Keep hands away from bending
shoe, rollers, and conduit when
bender is in use.
• Support conduit when unloading.
Conduit can become loose and fall
if not properly supported.
Failure to observe these warnings
could result in severe injury or death.
Wear proper apparel. Do not wear loose clothing,
gloves, neckties, rings, bracelets, or other jewelry
which may get caught in moving parts. Nonslip foot-
wear is recommended. Wear protective hair covering
to contain long hair.
Failure to observe this precaution could result in
severe injury or death.
Bending Conduit
Refer to the "Identification" section of this manual.
1. Plug the bender into a grounded 20 amp outlet.
2. Plug the pendant switch into the pendant receptacle
(6).
3. Turn on the main power switch (7).
4. Verify the shoe orientation.
For the 555DX only: If the pendant
display shows approximately the same
degree as the pointer on the shoe,
the shoe position is correct. If not,
rotate the shoe's engagement points
in the sprocket 90° by hand or zero
the pendant display. The shoe units in
the 12580 and 12581 bending groups
have drive studs that will align in only one position

with the holes in the sprocket. Re-zero the pendant
display to align the desired shoe pointer with zero
on the bender decal.
5. Press BEND or UNLOAD on the pendant until
the shoe is 5° to 10° before the starting point (0°)
(approx. –5° on 555DX pendant).
6. Load the conduit so that the bending mark is
aligned with the front edge of the hook.
7. Determine the angle to stop at to achieve the
desired bend angle from the bending decal or tables
in this manual.
8. Bend the conduit.
a. For 1-1/2" and 2" EMT or IMC conduit, use the
roller engagement arm (4) to raise the squeeze
rollers and position them so that both rollers
make contact with the conduit. Note that the
engagement arm can be placed in either of two
positions to facilitate hand or foot actuation.
Press BEND while applying pressure to the
engagement arm until the rollers hit their stop.

b. For all other conduit, press BEND while making
sure the bend mark stays at the front of the hook
until the conduit contacts the tail roller.
9. Continue to press BEND until reaching the desired
bend angle.
• On the 555DX pendant, use JOG to sneak up on
an angle. JOG will advance the shoe about 1/2°.
• On both the 555CX and 555DX pendant, use
BEND to sneak up on an angle.
Note: The angles displayed on the bending decal
and the pendant may not always be in sync due
to shoe casting variations, although they will be
consistent.
10. Press UNLOAD to free the conduit.
11. Twist the conduit to release it from the hook and
remove it from the shoe.
