Introduction
555BAT™ Battery-Powered Bender
555BAT™ Battery-Powered Bender
The 555BAT™ is intended to bend 1/2" – 2" conduit
and Schedule 40 pipe. The bender can be used in either
the vertical or horizontal bending positions. With fresh,
fully-charged batteries, the bender can perform over
100 bends in 2" rigid steel or IMC conduit.
The bender is equipped with two 12-volt batteries and
an onboard battery charger. A battery gauge with a
switch allows the operator to determine the charge level
of each battery. The bender can be used while charging
is in progress. The battery compartment is lockable to
prevent theft of the batteries.
Batteries
Two rechargeable 12-volt deep cycle batteries are
standard equipment on the 555BAT™ Battery-Powered
Bender. The batteries are connected in series to provide
24 volts to the bender. The batteries are intended for
use in any position, so the bender can be used to bend
in the vertical or horizontal bending positions.
To get the best performance from the batteries:
• Charge the batteries before first use.
• Charge the batteries after partial discharge rather
than after full discharge.
• Store the batteries at full charge; recharge every
6 months.
• Store the batteries at 68° to 77° F (20° to 25° C).
Batteries contain hazardous chemicals and produce
explosive hydrogen gas. Refer to the Material Safety
Data Sheet for Sealed Maintenance Free Lead Acid
Batteries for further safety information.
When replacement is necessary, replace with two
PowerSonic Model PS-12600 batteries, or equivalent
batteries with the following characteristics:
• 12-volt
• sealed construction
• rated by the manufacturer for use in any position
• deep-cycle type
• capacity of 60 amp-hours nominal
• dimensions as illustrated
Battery Dimensions (Maximum)
10-3/8" (26.3 cm)
Hole Diameter to be
Suitable for 5/16" Bolt
7-3/8" (18.7 cm)
9" (22.8 cm)
10.25" (26 cm)
Battery Charger
The onboard battery charger will charge new, fully
discharged 60 amp-hour batteries in 12 hours or less.
Larger batteries require more time to recharge. After
the batteries are fully charged, the charger switches
to a “float” mode to prevent overcharging the batteries.
The float mode will keep the batteries at full charge
indefinitely without overcharging.
The charger can be used while bending is in progress.
Note: Using the bender continuously to bend large
diameter conduit while charging will deplete
the batteries faster than the charger can
charge them.
See the battery charger instruction manual for a
complete set of safety information and operating
instructions.
Replacement batteries must be
rated by the battery manufacturer for
use in any position. Other batteries
may leak acid when the bender is
transported or used in the horizontal
bending position.
Failure to observe this warning can
result in severe injury or death.

Operation (cont’d)
555BAT™ Battery-Powered Bender
Adjusting the Squeeze
When bending 1-1/2" – 2" EMT or IMC, the roller
support must be engaged so that it contacts the conduit;
the pressure against the conduit is the “squeeze”.
Due to variations in conduit, the standard adjustment
may provide too much or too little squeeze. If the
conduit develops excessive side marking when bent,
the squeeze is set too high. If the conduit becomes
excessively oval or wrinkled, the squeeze is set too low.
1. Use a screwdriver to loosen the set screws.
2. Use a wrench to rotate both adjusting bolts 1/2 turn
clockwise to INCREASE squeeze or 1/2 turn
counterclockwise to DECREASE squeeze.
Note:In order to distribute the load evenly,
adjust both bolts to the same setting.
See the illustration.
3. Tighten the set screws.

Offsets
An offset is used to route the conduit around an obstruction. To make an offset, two equal bends are required.
The distance between the two bends is the center-tocenter distance.
When working past an obstruction, it is necessary to
determine the location of the first bend. The center-tocenter distance is then used to determine the location of
the second bend. When working toward an obstruction,
it is necessary to determine the location of the second
bend. The center-to-center distance is then used to
determine the location of the first bend.
Working Past an Obstruction
1. Select the size and type of conduit. Measure the
height of the obstruction and the distance labeled
LENGTH. Determine the angle to be used.
2. Find the table that corresponds to the size and type
of conduit selected in Step 1.
3. To the right of the size and type of conduit, find the
dimension labeled X. Subtract X from LENGTH.
Place the first bending mark this distance from the
end of the conduit.
4. Under the column labeled ANGLE, find the appropriate angle. Find the row labeled L1. In the row at
the top of the page, find the height (H) of the offset.
The number shown at the intersection of row L1 and
column H is L1. Place the second bending mark L1
inches from the first bending mark.
