Do not use if damaged: 

If the pump doesn’t work or the rework station becomes 

faulty, discontinue using immediately. To comply with safety standards, the pump 
or other part must only be replaced by authorized technicians as special purpose 
tools are required. Only the technician is permitted undertake repairs. Use the 
original replacement part only. 

 

  Remember unplug in the power cord: 

The station must be switched off and the 

power cord must be unplug-in before replacing the fuse in AC socket in rear side of 
the machine.   

 
 

PRODUCT FEATURES 

  With specially intelligent chip microcomputer control design, double LED display 

operate by pressing keys, make it convenient and comfortable operation. 

 

  Temperature and air blow by digital display readout, easy to read.   

 

  With the high power heating element, heat up quickly, the momentary power can 

reach 550W. 

 

  Temperature adjustable, suits for removing QFP, SOP, PLCC or SOJ chips etc., 

      especially the built in static free circuit design is safety for the sensitive elements 

like CMOS ICs.

 

 

◆ 

Auto-cooling design: When the power switch off, the cooling system will begin to 
work automatically, the temperature falls down to 7

5℃(167℉) 

to protect the 

heating element from burning ..

 

       

 Heating element auto-protecting function: When heating element reaching a high        

temperature which can be protected automatically, to lasting the life of heating 
element.   
 
 

PRODUCT DESCRIPTION 

The temperature controlled Hot-Air LF-852D SMD rework station built in an 
intelligent microcomputer chip which is specially designed for the present lead free 
SMD chips such as SOIC, CHIP, QFP, PLCC, BGA etc reworks to meet RoHS 
requirement. This appliance equipped with a high power heating element and gets very 
fast heat up time. A high-quality sensor and heat transfer technology ensure precise 
temperature regulation is essential for making consistent, reliable. The aluminum 
housing has the advantages of strong structure, good heat sink and effectively resistant 
of electro-magnetic interference.
