h.

 

Leave a space of 30cm or more behind the rework station for the upper part to move and rotate. 

2.

 

Power supply: 

a.

 

Use a power supply with little fluctuations in voltage. 

b.

 

Fluctuation: 220V±10  

c.

 

Frequency fluctuation: 50Hz±3  

 

D. Safety Cautions    

                                    

1.

 

Don't blow to the rework station directly when it is working, or there will be a negative 

difference from the surface of the heating board, thus some parts will be burnt out. 
2.

 

After it is started, the high temperature area should not touch any objects, or it will lead to a fire 

or explosion. The PCB and other parts should be put on the PCB bracket.  
3.

 

No vibration. Handle it gently. 

4.

 

Don't touch the heaters with your hands when it is working, or you will get hurt. 

 
 
5.

 

Don't use combustible spray, liquefied and flammable gas near the rework station after it is 

started. 
6.

 

Don't try to re-equip the machine, or there may be a fire or an electric shock. 

7.

 

There are high-pressure parts in the circuit box. Don't disassemble it. 

8.

 

If some metals fall in the rework station when it is working, turn off the power immediately. 

After it is cooled down, get the metal out, and clean the machine. If not, there may a smell when the 
machine starts working next time. 
9.

 

When the rework station's temperature rises abnormally or smokes, turn off the power and 

inform the service technicians to repair it. Turn off the power of the circuit box and the the machine 
while moving the rework station. Hold the plug when we remove the wire, or it will lead to a poor 
contact then the machine can't work very well. 
10.

 

Turn off the power when stop using it. 

11.

 

Don't put the rework station on the wires, or there may be a failure, a fire, or an electric shock. 

12.

 

Before you use the machine, you must read the instructions attentively. 

Note: when the machine works, it will produce some smell. So ensure the comfortable, healthy and 
safe operation environment, please keep the air in circulation.
