Pendant
Control
Upper
Roller
Frame Stop
The bender control pendant consists of a zero light, a green power
light, a jog push button, a push button for “Bend and Return”. An
8’ electrical cord connects the pendant to the bender frame. The
bender can be used in a horizontal or vertical position.
The end plate contains an ON-OFF switch which is also a circuit
breaker. When the switch is turned on, the two leds will flash red,
then green to indicate normal function.
To avoid damaging the bender control circuit, an input voltage
sensing system is built into the control circuit. If input voltage is less
than 92 VAC or higher than 132 VAC the bender will shut off. One of
the two LEDS located on the end plate will light to indicate whether
high or low voltage exists.
Re-set the bender by turning unit off then on again. If the incoming
current voltage has not been corrected, the bender will not operate.
The voltage range must be within 92 VAC to 132 VAC. Any situation
which causes a voltage drop or increase must be corrected before
using the B2000 Bender.
Voltage drops may be caused by:
• Extension cords that are too long.
• Extension cords made of light (16-18 gauge) wire.
• Multiple power tools on a single circuit.
• Other devices which require high amperes to operate.

6.0 MAINTENANCE
Figure 1
B2000 Bender Assembly
Periodic general maintenance to the bender may be required to
reduce the risk of malfunctioning rollers, sprockets, gear teeth,
and/or chains. These parts can become dirty, worn, or damaged
over time and may need to be greased or cleaned. Pressurized
air can be used to clean any dust or residue inside the bender
housing. The bender should not make any uncommon noises such
as rattling during use. If this happens, turn off the bender and
perform an inspection on the machine.
A troubleshooting aid exists on the printed circuit board mounted
to the inside of the operating handle. If all systems are functional,
a white L.E.D. (pictured in Figure 13) will flash once every two
seconds while the machine is powered up.
Error codes consist of different light patterns.
1. Blink twice = the motor is over heated.
2. Blink three times = limit switch has failed.
3. Blink 4 times = pendant control malfunction.
In addition the L.E.D. will be steady on if the bend or return button
is being pressed.
7.2 Forklift Transportation
1. Rotate bender to the horizontal bending position.
a. Pull handle end of the bender to remove the preload applied
on the positioning pin of the bender (Figure 14, #14), and
pull locking pin.
b. While pulling positioning pin, carefully raise the handle end
of the bender until the sprocket housing (Figure 14, #4)
locks in the horizontal position.
2. From the back of the bender opposite to the handle, insert forks
into fork tubes. Refer to decals located on frame for detailed
instructions.
3. Move to the desired location.
7.3 Lift/Hoist Transportation
1. If nylon sling is being used, ensure sling is long enough to
avoid contact with the bender. Bender should be hoisted in the
vertical bending position only.
2. Confirm that the Roller Housing (Figure 14, #20) and Upper
Roller (Figure 14, #12) are in place and locked.
3. Loop the nylon sling through the End Plate Lift Hook
(Figure 14, #26). DO NOT HOIST BENDER USING THE HANDLE
(Figure 14, #38).
4. NOTE: End Plate Lift Hook can also be used for job site tethering
for added security.
