For using a desoldering tool in good condition, it is recommended to conduct a daily check after every use and a periodic inspection depending on the frequency of use in a correct way.
Filters prevent flux from invading the station.
Always install filters when using a desoldering tool and inspect them periodically to ensure that they are not contaminated with flux or solder.
Early replacement can prevent solder suction performance and pump failure.
