Caution High Temperature Operation

 

Do not use the LF- 852D near ignitable gases, or other inflammable materials. Both 
nozzle and hot air are extremely hot and can cause burns. Never touch the nozzle 
and heater assembly or allow the hot air to blow against your skin. Initially, the iron 
may emit white smoke, but this will soon dissipate. 

 
3. Be sure to cool the unit after using. While the power switch off, the unit will 

automatically blow cooling air through the pipe for a short period of time. Do not 
disconnect the plug during this cooling process. 

 
4. Do not disassemble the pump. 

 

  If the pump or other critical internal components become faulty, discontinue its use 

immediately. Please return to your vendor or its authorized repairers for proper servicing. 

 
5. Disconnect the plug while the unit is not in use. 

When the power cord is connected into the power supply, the unit has a little flow of 
electricity; even the Power Switch is in off position. So when you don’t use the unit 
for a longer period of time, disconnect the plug. 

 

Operation Setup 

1.

 

Select the Nozzle that matches the size of the IC. Attach the nozzle when both the 
heating element and the nozzle are cool and the unit is turned off and unplugged.   

 
2.    Loosen the screw on the nozzle. Attach nozzle. 
 

IMPORTANT

: Do not force the nozzle or pull on the edge of the nozzle with pliers. 

Also, do not tighten the set-screw too tightly. 
 

Suitable for desoldering of SMD components such as SOIC, CHIP, QFP, PLCC, 
BGA etc. 

 
 

OPERATING INSTRUCTIONS 

Caution: 

Check carefully for any damage during transportation and ensure that the 

working voltage matches your power supply before plugging in the station. 

 
1. Ensure that the base unit power switch is in the “OFF” position. 
2. Plug in AC power cord and turn “Mains power switch” to “ON” position then the 

temperature LED and wind LED display will be ON and show the value. 

3. Press “

” or“

”key on the left side of the front panel to choose the desired 

temperature. When the temperature reaches to the desired temperature that the 
heating indicator light will be flashed on and off to maintain the set temperature .The 
temperature will change 1 degree by pressing the keys “

” or“

” at a time.
