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.

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.
