Blower/vacuum air filters
The filters should be cleaned and changed regularly so that contamination does not block the air line.
This is important for the toxic gases generated during soldering to be filtered without problems.
Soldering tip/iron
Always keep the solder-coated area of the soldering tip coated with a small amount of solder.
Oxide coatings on the tip can reduce thermal conductivity.
The maximum thermal conductivity is obtained when the tip is coated with fresh solder.
Replacing the soldering tip
1. Always switch off the soldering station before replacing the soldering tip.
2. When the soldering tip is hot, use a heat-resistant pad to pull the soldering tip out.
3. Push the new soldering tip completely into the soldering iron. If the soldering tip is damaged or
not placed correctly, "PLUG" appears on the display.
Replacing the hot air gun heating element
The heating element is located in the middle part of the heat gun. Typically, the life of a heating ele-
ment is around a year (under normal conditions).
1. Loosen the three screws that secure the handle.
2. Pull off the plastic tube.
3. Remove the earthing.
4. The quartz glass and thermal insulation are built into the inside of the heat gun. Disconnect
the cable and pull out the heating element.
5. Insert the new heating element and reconnect the cable. Avoid any friction on the wire of the
heating element.
6. Reconnect the earth after the heating element has been inserted.
7. Reinstall the handle.
