I. MAIN SPECIFICATIONS
II. SAFETY INSTRUCTION
WARNING: THIS IS A VERY DANGEROUS MACHINE! FAILURE TO FOLLOW THE
SAFETY RULES MAY RESULT IN SERIOUS PERSONAL INJURY
As with all machinery there are certain hazards involved with operation and use of the
machine. Using the machine with respect and caution will considerably lessen the
possibility of personal injury. However, if normal safety precautions are overlooked or
ignored, personal injury to the operator may result.
This machine was designed and constructed for roll forming metal plate and some
similar material. We strongly recommend that this machine SHOULD NOT be modified
and/or used for any application other than for which it was designed. If you have any
questions about its application, do not use the machine until you contact us.
Read all instructions before using this very dangerous machine!

National Electrical Code and local codes and ordinances. This work should be done by
a qualified electrician. The machine should be grounded to protect the user from
electrical shock.
2. TRANSPORTATION (CERTIFIED FORKLIFT DRIVER IS REQUIRED)
1. Each chain or strap belt should be capable of lifting weight over 5,000LBS
2. The strap belt must be arranged properly as per cavity center of wooden box.
3. The forklift driver should be a qualified & trained person.
4. Machine should be loaded at the cavity center of the truck to avoid any sliding.
5. After loading onto truck, use steel wire to fix the machine body on truck and ensure

3. POSITIONING & CLEANING
·Site : When select site, ensure there is free space for material handing around the
machine.
5
·Foundation: The machine requires a plain & stable ground to have an excellent bending
performance. It is better to be fixed on 150mm reinforced concrete ground.
·Leveling: Four sheet shims are placed under the adjusting bolt of the foot plate, the
machine is leveled by level gauge.
·Cleaning: Use a liquid solvent such as kerosene or white spirit to remove the protective
coating and any dirt from the up-painted surface of the machine. Don’t disturb any
moving parts until the full surface has been cleaned.
4. ELECTRICAL CONNECTION
·Before connecting machine into local 3-phase ac source at your plant, please double
check same voltage and phase.
·Connect the ac source with machine cable which has 4 wires, correctly, the ground wire
must be connected with ground.
·After connecting ac source to shaft, check motor rotation is in the correct rotation
direction as per the arrow on the motor.
·If wrong direction, please immediately stop motor to avoid motor damage. Please

III. OPERATION INSTRUCTION
For models#
PBR-0412E/ PBR-04316E / PBR-0425E / PBR-0510E / PBR-0610E/ PBR-0810E &
PBR-1010E:
1.Press the down push button to move the bending roll down
2. Put the sheet metal material into the rolls as picture shown and crank the big
hand-wheel to barely touch the material.
Width of the sheet metal – is necessary to form the designed size circles is the 1st
6
consideration in circle forming. Decide approximate length of material need. Use the
formulary “C=πx ID”(C is Circumference;πis 3.1416; ID is Internal Diameter).
Sample:ID=12”, operator need to prepare material length approximate 37.7” or
approximate length of material which need.
3.Push the up/down buttons to move the bending roll up/down for right position,
and press foot pedal to roll the sheet metal material.

4. Press the foot pedal to make the rolls turn forward and reverse to roll the
material back and forth completely to make the part.
5. Press the foot pedal When finished with that part, then turn the cone
attachment down 90 degrees.
Loose this cone attachment

Press the foot pedal Loosen this locking bolt, get ready to swing out the top
roller.
6.Rotate this handle counter clockwise 90 degrees, and hold and pull the top
roller shaft to swing out the top roller, then remove the part out of the top
roller. Then push the top roller back into the housing, and turn this handle
clockwise 90 degrees, make sure the top roller sits correctly. Turn the
black knob of the locking bolt to lock the top roller in position.
This handle is to
