2、Installation：When installing machine should be installed in a horizontal on the bottom of foundation,

level the machine very well, using leveling pads or foundation bolts.

IV. Safety inspection and Safety rules during and/or before operation

To ensure safety, it is necessary to do the following inspections for this machine after installation.

Check if the transportation procedure has influenced the accuracy and functions of the machine.

Check if the foundation of the machine is appropriate.

Check if the machine's main power switch should have earth wiring connected.

Use the multitester to check the stability of the three-phase voltage, and the low voltage must be the range of

208V-240V or high voltage must be 440V-480V, can not use voltage higher than 480V.

Check if the control panel function and push button are functioning

Check emergency stop function.

Check if safety protection accessories are functioning well

Check if other accessories, including hydraulic and pneumatic ones, are connected well (including transformer etc.)

Check if the oil amount indicator and air pressure indicator are normal.

Make sure no obstacle is around machine and control system.

Make sure no personnel are in dangerous area.

Tools and any unnecessary items are not allowed on the machine, moving parts, or similar locations.

6

Before pressing/switching any button/switch always confirm that the button/switch is the correct one and never touch

a switch accidentally. Malfunction and potential danger might result.

Do not operate when wearing gloves or loose clothing. Malfunction and potential danger might result.

Do not touch switches with wet hands, an electric shock could occur.

If a work requires two or more operators, the cooperation among each operator must be well organized, every step of

each operator should be clarified to avoid potential danger.

Tools should be consisting with the machine's specifications, such as dimensions,weight and types.Grip workpieces

carefully to minimize movement and vibration between workpieces.Too much movement/vibration might result in

injuries of personnel, or damage the machine or workpiece.

Stop the machine before replacing workpiece, and reserve sufficient distance between workpiece and machine.Safety

for the electrical connection/disconnection

Electrical connection:

A cable with four wires is supplied to connect your machine into the 3 phase power supply.The exact power source

voltage, frequency, and number of phase shall be checked according to the installation diagram and circuit diagram.

The correct direction of main motor should be checked after connecting.

Electrical disconnection:

Be sure to disconnect this machine from power source, when you want to stop the job for maintenance or adjustment.

Grounding

The grounding of this model is carried out b y connecting the yellow/green terminal of supply cable to the grounding

terminal of power source. Be sure to ground your machine before connecting machine to power source in any

situation.

Warning!

Do not disconnect grounding terminal before disconnecting power source.

Description for the safety function of this machine

The following safety functions are equipped with this machine. Be sure to check and

ensure the correct function before you start to operate your machine:

The emergency stop device:

The machine is designed to be immediately stopped under emergency situation. As soon

as this device is actuated, any movement will be stopped in a short time after the actuation of emergency stop switch

(E-stop).

Be sure to check that machine action will stop immediately after this button is pressed and will not cause any action

when this button is disengaged.

V. Machine adjustment

CLEARANCE CHART

Before operation, please use the following formula to calculate & adjust the gap between the punch & die according to

the thickness of the work piece

For the following,A=material X2,for example,if you want to process 10Ga. thickness material,the

A=0.137X2=0.274inch
B=thickness of material -0.5~2mm. For example,if the thickness of the material is 2.0mm,the B=1.0mm. If the

thickness of the material is 10Ga, B=0.098” ( 12Ga.)

7

How to adjust A and B, please pay attention to the following steps:

1) Adjust A: A can be adjusted through No.3 hand wheel left and right to adjust A.

2) Adjust B: Loose No 2 after adjust to the right pressure then tight No.1

8

TABLE CROWNING COMPENSATION

If the angles of work-piece two sides are both on 90 degree,but middle side only 89 degree,Micro adjusting

screws at bending left and bottom beam for compensate the middle has the same angle.

1) Open the top beam,and then turn off the machine power

2) Tight screws A-G at upper beam and folding leaf,and make screw tight following different work-piece

crowing situation.

VI. Lubrication

Please lubricate the following oil fittings ① ② ③ ④ four times a day, using lubrication oil # Shell

Tonna-33

10

VII. How to use back gauge

This machine comes with a manual back gauge. Before first time use, please install the back gauge
first. Two support arms are mounted on the rear side of the table by screw 1 and 2, the stop bar # 6 on the

back gauge is mounted by screw 3.
Adjust the distance of back gauge: Loosen the butterfly nut # 4 and then T-nuts are released. Move the stop
bar # 6 back and forth to adjust the distance of the back gauge you need. Then tighten screw # 4.

Operation Instruction

1)Turn the main power switch on the electric box to “ON” position

2) then power light is on , turn E-STOP RESET clockwise to fully release the E-stop push button, and
press bush button for pump start

15

3）Angle set up: turn the black locking knob(circled in red ) to counter clockwise to release the set-up bar and
set up the bending degree you need then tighten the black locking knob, the bending angle degree can be
set-up from 0-135°。

This machine has two operation modes: one is for Auto cycle, and 2nd is for inch ( jog).

4)-1 on inch ( jog ) mode:

Press unclamp foot pedal, the top beam raises up, please insert the material in ,then press clamp pedal to
close down the top beam with fingers. ( caution: the top beam must be closed down tightly, otherwise,
The bending leaf will be not lifted up to make bend. ) press BEND foot pedal to jog the bending leaf up.

Or push the following circled black controller up to BEND position, the bending leaf will go up joggly and

push the black controller down to release position, the bending leaf will go down joggly.

16

4)-2 on Auto cycle operation mode:

Press BEND foot pedal, the bending leaf automatically go up and make bend and then automatically go
back to the bottom postion and stops to make one autocycle bending. Or 2nd way, push and release the
above circled black controller up to BEND position, the bending does the same automatic cycle bending and
then stops.

X.Troubleshooting

Troubles Possible cause Remedy

Hydraulic cylinder crawling

Hydraulic or pipe has air Start the hydraulic system and forth several times to

the maximum stroke, forced exclusion of air; seal the
pipeline and system.

Somewhere a negative
pressure in the hydraulic
cylinder

Locate a negative pressure at the hydraulic cylinder
and sealed, then exhaust the air.

Ring seal too tight Adjustment ring, so as not to loose not tight, to ensure

that the rod can be pulled back and forth by hand.

Cylinder wall or piston
surface strain, badly worn or
local corrosion

Boring the cylinder bore, the piston reassortment

Leakage of the hydraulic

cylinder

Cylinder bore and piston with
the gap due to wear resulting
in increased tolerance, rod
surface damage

Repair rod damage

Seal the edges injury or aging

Replace the seals

Pipe joint is not seal tightly

Replace the seals

Hydraulic cover is not seal
tightly

Check the seal contact surface machining accuracy
and aging, be replaced or repaired.

Due to poor exhaust air
temperature adiabatic
compression cause local
damage seals

Inspect the exhaust system, or additional exhaust,
timely exhaust.

Sound and noise

1) hydraulic cylinder has air

2) Cylinder rod lack oil

1)Slow movement of the piston several times, each
time went to the top, to exclude gas tank, you can
eliminate this serious noise, but also to prevent seals
burns.

2) cylinder rod oil can also cause less noise, this time
should be oiled at the pole.
