Operation
Precautions
To extend the life of the heating element in the hot air gun, do not use the device continuously at a low
airflow and a high temperature. Allow the heating element to cool after maximum 20 minutes of usage.
Place the hot air gun back in its stand when not in use.
Make sure that both heater and nozzle are cold before attaching the nozzle.
Warning! High temperature.
Both nozzle and airflow are extremely hot and can cause severe burns.
Never touch the nozzle and heater assembly or allow the hot air to blow against your skin. When used for
the first time, the hot air gun may emit some white smoke, but this will soon dissipate.
Caution!
Always let the unit cool down after use. After switching off, leave the power cord plugged in for a
few minutes. When you switch off the unit, the automatic cooling function blows cooling air through the
heater pipe for a short period. This protects the heater from damage and extends its lifetime. Do not
disconnect the mains plug during this cooling process.
Do not disassemble the pump. If the pump or other internal components become faulty, stop using the
device immediately. Contact your vendor or its authorised service centre for repair.
Setup
Caution!
Do not force the nozzle or pull its edges with pliers. Do not over-tighten the screw.
1.
Switch off the device. Wait until the automatic cooling process has stopped, and then disconnect the power
cord.
2.
Wait until both heater and nozzle are completely cold.
3.
Select the nozzle that matches the IC size.
4.
Loosen the screw on the nozzle, slide the nozzle on the heater pipe, and fix it with the screw.
5.
Plug in the power cord and switch on the station

QFP Desoldering
1.
Hold the nozzle directly over the IC and wait for the hot air to melt the solder.
Caution!
Be careful not to touch the IC or the leads with the nozzle.
2.
Once the solder has melted, remove the IC using pliers.
3.
Clean the remaining solder chips with a wick or the desoldering iron.
QFP Soldering
1.
Apply a suitable quantity of solder paste and flux (preferably no-clean) and place the SMD on the circuit
board.
2.
Preheat the SMD.
3.
Heat the lead frame evenly.
4.
When soldering is finished, wash the area with a defluxer.
5.
Inspect all joints carefully.

Cleaning and Maintenance
11.1
General
Perform only the maintenance as described in this user manual. Contact an authorised dealer or service
agent for any other maintenance or repair.
If the irons, gun, or station become faulty or, for some reason do not operate normally, return them to the
service department of your authorized dealer or service agent.
Clean the outer cover of the irons, gun, and station with a damp cloth and a small amount of liquid
detergent. Never submerge the unit in liquid or allow any liquid to enter the case of the station. Never use
any solvent to clean the case.
Use only original replacement parts.
