二Installation of BGA rework station
（一）Installation sites
In order to ensure that the useful life of BGA rework station, installation of repair station must
meet the following conditions:
1、Awayfromflammableandexplosivematerials
2、Do not splash water or other liquids
3、Well-ventilated,dryplace
4、Stable , flat areas less susceptible to vibration
5、Place lessdust
6、Prohibit Placing heavy objects on top of the control box
7、Without the affect of air-conditioners,heaters and fans
8、Reserved for 30cm to move and rotate around the upper for the back of rework station
(二)Power Requirements
Voltage fluctuations: 220V±10
Frequency fluctuations: 50Hz±3

三、Safety Precautions of rework station
1、Do not use fans or other devices directly to the repair station hair when it works, otherwise it
will lead to negative differential heating plate surface , burn the workpiece.
2、When turned on, high-temperature heating zone can not be any direct contact with the object , it
may cause fire or explosion ,and the PCB workpiece should be placed on the PCB support
shelves.
3、Do not shake rework station , and move gently
4、Do not touch the high fever area , otherwise it will burn
5、When turned on, do not use the flammable spray , liquid or flammable gas near the repair
station.
6、Do not try to modify rework station , otherwise it will cause fire or electric shock.
7、Electrical box has the high-voltage components , do not attempt to disassemble
8、If the metal objects or liquids fall into the repair station when it works , immediately disconnect
the power , unplug the power cord until the machine to cool down , then completely remove
litter , dirt ; if dirt left ,there is odor when reboot.
9、When abnormal heating or smoking,immediately disconnect the power , and inform the
technical service to repair.It needs to disconnect the wires between the electrical boxes and
machine parts,and have to hold the plug,otherwise it leads to poor contact ,and does not work.
10、Note that the repair station not to press or run over other electrical equipment or power lines or
communication cable , and it may cause device malfunction or cause fire or electric shock.
11 、Before use the rework station, you must read this manual carefully
