To desolder the component you will need to use the solder sucker (solder pump). You should arm it by pushing its lever down. To use it, you should press its button, which is a trigger: its lever will get back to its normal position sucking everything located near its tip, hence its name. It works like if it was a small vacuum cleaner.

Here is the process: with one hand, you should melt the solder located at the component’s terminal, with the other, you should handle the solder sucker and aim its tip to the melted solder and press its button. The melted solder should be all gone.

Here is a tip: never keep your solder sucker armed after the job is done. This will make it to lose its pressure.

You also must pay attention to the correct way of handling the soldering iron, as we show in Figure 15. If you are left-handed you should invert the hands, of course.
