6.2 Replacing the spark plug connector and the high-voltage cable
•
The spark plug connector and a defective high-voltage cable can only be exchanged at the
manufacturer’s premises.
These parts are also available as a complete spare part mod-
ule by stating the length of the ignition lance.
6.3 Replacing the spark gap
Caution: high-voltage!
Put switch S1 in its O-position before working on the appliance. Remove fuse F 1 (see Fig. 3)
immediately after opening the cover lid. A voltage of approx. 1 600 V for the ignition process will
be generated in the appliance, which may still be applied for to the HV-capacitor and to the spark
gap for a few seconds, although the igniter has been switched off. After the casing has been
opened, the heat sink (E1) next to the HV-capacitor (C1) will become visible. It connects the two
spark gaps (see Fig. 3).
Loosen the two M 3 nuts with a 5.5-mm socket wrench, pull off the toothed lock washers and
remove the heat sink. Turn out both spark gaps. Please take care when fitting in the new spark
gaps that they are screwed in finger-tight (i.e. without using any tools). The heat sink can be re-
assembled and fixed with the M 3 nuts and tooth lock washers. Reinsert fuse F 1 and close the
cover lid.
