WARNING!
Improperly connecting the grounding wire can result in the risk of electrical
shock. Check with a qualified electrician if you are in doubt as to whether
the outlet is properly grounded. Never remove the grounding prong from
the plug. If the cord or plug is damaged, have it repaired before using. If the
plug does not fit the outlet, have the proper outlet and/or plug installed by
a qualified electrician. The Jancy Slugger Bender must be plugged into an
appropriate outlet, properly installed in accordance with all codes and ordi-
nances. The plug and outlet should look like those in Figure A.
grounding instructions
Use only 3-wire extension cords, that have 3-prong grounding-type plugs and 3-pole receptacles that accept
the machine’s plug. Replace or repair damaged cords before use. Make sure your extension cord is in good
condition. When using an extension cord, be sure to use one heavy enough to carry the current your product
will draw. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating the
machine. Jancy recommends using a minimum 12 gauge extension cord not to exceed 50 feet.
extension cords
This machine is designed to run on either 110 or 220 volts. Operating this machine on voltage other than that
stated on the machine will increase the risk of fire, and/or personal injury.
110 Volt machines must be plugged into a circuit that is controlled by a minimum 25 Amp circuit breaker.
220 Volt machines must be plugged into a circuit that is controlled by a minimum 15 Amp circuit breaker.
Failure to use the minimum rated circuit breakers will increase the risk of fire, and/or personal injury.

If possible, build a ramp at the front of the machine.
With some assistance, roll the machine off of the pallet using caution not to drop it to the ground or onto
anyone's feet or hands.
Method #2:
Lift machine off of pallet by using a forklift, or overhead lift, etc.
Position a single lifting strap around the upper box tube at the front end of
the machine (as pictured).
ONLY RAISE THE MACHINE HIGH ENOUGH TO REMOVE THE PALLET,
SET THE MACHINE ON THE GROUND AS SOON AS POSSIBLE.
Alternatively: Remove the two middle 2X6 boards from under the machine
by removing the screws at both ends. Position the forks under the lower frame. Only lift the machine
high enough to remove the shipping pallet.
Have a qualified electrician install the appropriate power connector to the end of the
power cord.
Remove all contents from packaging and inspect to ensure no damage was incurred during shipping. Your JB2400
package should also include the following:

operating instrucions
The Jancy Bender is designed to accommodate a wide variety of tube and pipe diameters and wall thicknesses.
To ensure a quality bend, use the appropriate sized tooling for the material being bent. Example: 1.50” pipe is
1.90” OD, where as 1.50” tube is 1.50” OD. In most cases a Center Line Radius (CLR) of three (3) times that of
the outer diameter should be used. See Appendix A of more information on bend quality and troubleshooting.
The Jancy Bender is fitted with a lockable master switch. It is recommended that the switch is locked when not
in use to prevent untrained or unauthorized use of the machine.
Turning on the power
- Rotate the main power switch handle clockwise to the “ON” position.
- To turn the machine off, rotate the handle counter clock-wise to the “OFF” position.
Form die assembly installation
Caution!
The forming dies can be extremely heavy. Use assistance or mechanical means to lift the larger form dies
into position.
Caution!
Do not drop the form dies, damage to the machine and/or personal injury may result.
- Install form die over the central locating pin.
- Rotate die until all of the smaller drive pins are engaged, lower form die completely.
Pressure die assembly installation
- Remove the pressure die pull handle.
- Position the pressure die assembly in the opening of the pressure die pivot, with the bronze pressure die
towards the clamp arm. Insert pull handle into the pressure die pivot assembly.
- To re-position pressure die pivot assembly, loosen and remove the three (3) 3/4-10 SHCS that hold the pressure
die base to the upper bending arm.
- Insert test material into the clamp arm, and rotate the pressure die assembly into place.
- With the “cam” handle in the full rearward position, position the pressure die assembly approximately 1/4” - 3/8”
from the form die.
- Locate the threaded holes in the upper bending arm just behind the bolt holes in the pressure die base. Position
the pressure die pivot assembly over these holes and install and tighten the two (2) 3/4-10 x 1.50” SHCS. Insert
the 3/4- 10 x 7.50” SHCS into the “cam” assembly, do not tighten yet.
- Rotate the “cam” assembly until the pressure die barely touches work piece, but allows the pressure die
assembly to beswung out of position. Tighten the 3/4-10 x 7.50” SHCS.

WARNING: Before powering up the machine, ensure that all moving parts are clear
of obstructions, all bolts have been secured, and that the control lever is in the
center/neutral position.
- Ensure that the appropriate tooling is installed for the bending material.
- Turn main power on.
- Spray pressure die with white lithium based aerosol spray lubricant such as Jancy White Grease (#JB0810/
#JB0811).
- Insert material into the clamp arm, aligning the zero mark on the form die and the beginning of the bend.
- Rotate the pressure die assembly into position, adjusting the “cam” as necessary (see above section on pres-
sure die assembly installation).
- To make a bend, slowly raise the control handle to the upper position.
- Release the handle at the desired bend angle, taking into account the “spring back” of the material.
- Releasing the handle will return the lever to the center/neutral position and stop all bending/retracting motion.
- To retract the arms and reset the machine for the next bend, lower control lever to the down position, holding it
there until the arms are fully retracted.
- Rotate the pressure die assembly out of the way and remove the material.
- It may be necessary to tap on material with a mallet to dislodge it from the form die.
For repeatable bends:
This Jancy Slugger Pipe/Tube bender is equipped with a limit switch system to allow for repeatable bending.
To set up the machine for repeatable bends using test bend
material:
- Thread micro adjusting collar half way onto the macro collar
- Make a test bend to the desired angle taking into account the “spring back” of
the material.
- At the desired angle, loosen the macro collar fixing screw and slide the assem-
bly towards the limit sensor. Tighten the macro collar fixing screw when the light
on the sensor comes on.
To set up the machine for repeatable bends using the preset gauge:
- Estimate the amount of “spring back” for the material being bent.
- Add this amount to the desired bend angle, this is the "adjusted bend angle".
- Loosen the macro collar fixing screw and slide the assembly towards the limit sensor.
- Tighten the fixing screw at the adjusted bend angle on the “PRESET BEND TO ANGLE” gauge.
- Adjust the micro adjustment collar to fine tune the bend angle during test bending.
For best results and consistent repeatable bends, develop a routine for making the bend.
- Load the material in the same manner.
- Rotate the pressure die assembly into the same position.
- Do not adjust the “cam” or adjusting collars, once acceptable bends have started.
Once finished with the limit switch, return the adjusting collars to the most rearward position. This will prevent
the sensor system from being triggered accidentally.

troubleshooting
Problem: Solution:
Machine does not switch on 1) Check plug/power cord.
2) Check power distribution panel and
circuit breaker.
Machine stops working 1) Machine overload.
2) Material is too much for machine.
Turn off machine, let it sit for a few seconds,
then switch back on.
3) Move control lever to the down position to
release material.
Nothing happens when control lever is moved Bend angle limit switch engaged, move
adjusting collars away from sensor.
Inconsistent bend angles Incorrect “adjusted” bend angle used, adjust
“springback” amount.
Wrinkles on internal surface of bend 1) Pressure die and form die may be touching
2) Form die radius is too small for material, refer
to chart for correct former.
Excessive ovalization Worn pressure die, rotate or replace die.
Necking of material at beginning Pressure die “grabbing” material, spray pressure
and end of bend die with spray grease.
