Instructions of the desoldering iron gun

WARNINGS:

1. To avoid injury or damage to the desoldering gun, do not touch the metallic parts near the nozzle or use it near flammable items.

2. Always unplug the gun before any maintenance except for removing the solder waste.

3. If the pump does not work, clean the nozzle & heater and replace the filter immediately.

4. After use, the solder waste will be stored in the pipe. Clean it in time otherwise the solder waste will block the desoldering gun, or the solder waste will get oxidized (lead free solder’s melting point is 220℃, non-lead free solder’s melting point is 180℃), swelled and stuck on the inner wall tightly. It can't be removed even with the cleaning pin.

Please follow the steps below to clean the solder waste:

1. Push the knob up to unlock the back holder.

2. Take the spring out from the glass tube, then clean the solder waste.

3. Put the spring back to glass tube, then put glass tube back. Press the back holder, then the knob will bullet down and become locked automatically.

 Instruction：

1. After each operation is finished, let the desoldering gun suck in the air 3-5 times soon, which can clean the solder waste inside the pipe.

2. If the operation interval is about 20 minutes, use the cleaning tool to clean the pipe after having the desoldering gun suck in the air.

3. When you find the desoldering efficiency gets down, please use the cleaning pin to clean the pipe immediately.

4. If the operation interval is long, it is advised to adjust the temperature to about 200℃. When you use it again, you can reset it to the working temperature.

5. When the glass tube has absorbed about 1/2 solder waste, clean it immediately. When you find the filter is getting hardened, replace it immediately.
