OPERATING PRECAUTIONS
1. Make sure both heater and nozzle are cool before attaching the nozzle.

.
Caution High Temperature Operation
Do not use the LF- 852DII 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
NOTE: In ord to protect the pump during transportation , the pump in the
