Using the special pliers, strip off the insulation at the ends of the 0.35 mm2 wiring so that the length of bare metal is twice as long as the joint required (approx. 12 - 14 mm).
Fold back the bare metal to half this length.
Using the special pliers, strip off the ends of the 0.5 mm2 wire (approx. 6 - 7 mm).

Heat the crimp connector from the center outward until it is completely sealed and the adhesive comes out.
Set the hot air blower to the correct temperature (refer to operating manual).
When heating the connector, take care not to damage any other wiring, plastic parts or insulating material with the hot nozzle.

If the wire was originally taped, wrap it again with yellow insulating tape. If necessary, secure the wiring with new cable ties.
