ning tool (5 13 500 99).
Various suction nozzles solve many desoldering problems. The suction nozzles can
be changed easily; a suitable tool is integrated into the cleaning tool. The thread on
new suction nozzles should be smeared with „Antilocking paste".
Only change and clean suction nozzles when hot.
To avoid the suction nozzle seizing solid with the heat, the suction nozzle should be
unscrewed regularly and the thread smeared with „Antilocking paste".
In the case of a very dirty thread or a broken suction nozzle, the repair can be perfor-
med as follows:
1. Drill out with 4 mmø drill, maximum 11 mm deep.
2. Recut the thread with an M 5 / 12 – 24 UNC 2A tap, remove swarf.
3. Smear new suction nozzle with antilocking paste and screw in place.
Cleaning DSX 80
To achieve good desoldering results it is important to clean the desoldering head
regularly. This includes emptying the solder collecting container, replacing the glass
tube filter, as well as checking the seals. Correct sealing of the front faces of the glass
cylinder ensures full suction performance. Dirty filters affect the air flow rate through
the desoldering tool.
Various suction nozzles solve many desoldering problems. A suitable tool for chan-
ging the suction nozzle is integrated into the cleaning tool (5 13 500 99). The suction
nozzles can be straightforwardly and quickly changed using a short rotational move-
ment (approx. 45°C). When inserting and locking the suction nozzle, press gently
against the heater element.
Only change and clean suction nozzles when hot. To clean the suction nozzle bore and
the suction tube, use the cleaning tool.
In the case of heavy deposits of dirt in the cone area, it is not possible to insert a new
suction nozzle. These deposits can be removed using the cleaning insert
{5 87 067 94) for the heater element cone.
