Operation — Installing and Bending Conduit (cont'd)
negative sign on and off. Pressing the CLEAR NUM-
BER key changes the adjust angle to 0. Any adjust
angle may be displayed by pressing the keys for the
desired size and type of conduit while in the Accuracy
Adjust programming mode. Press ENTER to save the
adjust angle and exit the Accuracy Adjust programming
mode. Only the change to the last displayed value will
be saved. Press RESET to exit the Accuracy Adjust
programming mode without saving a program change.
Changes saved are to permanent memory in the bender
and can only be changed by reprogramming.
1/2" to 1-1/4" Conduit
Press the BEND key while maintaining conduit align-
ment, until slack is taken up. When the conduit starts to
bend, the digital display starts to count from zero and
show the angle to which the conduit has been bent.
Releasing the BEND key at any time during the bend
stops the bender. The bend can then be resumed from
the point it was stopped. As the conduit approaches the
programmed angle, the bender slows and then stops at
the programmed angle. After stopping at the pro-
grammed angle, the BEND key will function if released
and pressed again. The JOG key can be used to bend
beyond the programmed angle in 1/2-degree incre-
ments. Press UNLOAD until the shoe has rotated back
about 10 or more degrees, and twist the conduit to
loosen it from the hook. If the bend is complete, remove
the conduit from the shoe. For offsets and saddles,
press UNLOAD until the shoe returns and stops at the
load position, move conduit to align mark 2 with the
hook, rotate conduit 180 degrees, and make the next
bend(s) as before.
1-1/2" and 2" Rigid and 40 Mil PVC-Coated
Rigid Conduit
Make sure that the rollers are in the fully retracted
position to the right. Press the BEND key while main-
taining conduit alignment until slack is taken up. When
the conduit starts to bend, the digital display starts to
count from zero and show the angle to which the
conduit has been bent. Releasing the BEND key at any
time during the bend stops the bender. The bend can
then be resumed from the point it was stopped. As the
conduit approaches the programmed angle, the bender
slows and then stops at the programmed angle. After
stopping at the programmed angle, the BEND key will
function if released and pressed again. The JOG key
can be used to bend beyond the programmed angle in
1/2-degree increments. Press UNLOAD until the shoe
has rotated back about 10 or more degrees, and twist
the conduit to loosen it from the hook. If the bend is
complete, remove the conduit from the shoe. For offsets
and saddles, press UNLOAD until the shoe returns and
stops at the load position, move conduit to align mark 2
with the hook, rotate conduit 180 degrees, and make
the next bend(s) as before.

1-1/2" and 2" EMT, IMC and Aluminum Rigid Conduit
Note: For aluminum rigid conduit, set squeeze to the
minimum position.
Press or jog the BEND key while engaging the roller
system using the support roller engagement handle.
Apply sufficient force on the handle so that the roller
system reaches its position against the stops before the
conduit starts to bend. Supporting the tail end of a long
conduit may ease engagement when bending vertically.
Continue to press the BEND key while maintaining
conduit alignment until slack is taken up. When the
conduit starts to bend, the digital display starts to count
from zero and show the angle to which the conduit has
been bent. Releasing the BEND key at any time during
the bend stops the bender. The bend can then be
resumed from the point it was stopped. As the conduit
approaches the programmed angle, the bender slows
and then stops at the programmed angle. After reaching
the programmed angle, the BEND key will become non-
functional.
A roller support lock has been provided to free up one
hand. Once the roller support engagement handle is
brought up into position, a locking cam holds the handle
in place and bending can proceed from this point
without further operator action on the handle. Lifting up
on the tail of the conduit makes roller engagement
easier. For 1-1/2" EMT, it may be easy to go past the
cam; if this happens, raise the cam by hand and rest the
handle against it. If you wish to change the position of
the conduit and it is held too tightly to move, lift up on
the cam while supporting the handle and allow the
handle to retract slightly. Reposition the conduit and
relock in place. The UNLOAD key will not function while
the locking cam is engaged.
Note: If you are unable to raise the handle enough to
engage the locking cam even after lifting up on the tail
of the conduit or pushing down on the nose, the
squeeze is probably set too high. If the handle easily
passes by the cam on 2", the squeeze is probably set
too low.
Press UNLOAD until the shoe has rotated back about
10 or more degrees, and twist the conduit to loosen it
from the hook. If the bend is complete, remove the
conduit from the shoe. For offsets and saddles, press
UNLOAD until the shoe returns and stops at the load
position, move conduit to align mark 2 with the hook,
rotate conduit 180 degrees, and make the next bend(s)
as before.
