Repairs
Warning!
Only suitably qualified staff is authorized to exchange the wear parts. Use only original spares.
Disconnect the battery charger during any repair work. Put switch S1 in its O-position before work-
ing on the appliance. Remove fuse F 1 (see Fig. 3) immediately after opening the cover lid. When
repairing the spark plug, disconnect the HV-cable from the igniter (by pulling out the HV-plug).
6.1. Replacing the high-energy-spark plug
•
Disconnect the HV-cable from the igniter
•
Unscrew the worn-out high-energy spark plug
(warning: high temperatures can be possible!)
•
Slide off the protective tube from the replacement plug; the thread has been treated with a
high-temperature paste (which prevents the spark plug from getting stuck in the socket)
•
Insert the new spark plug into the ignition lance and screw it in finger-tight
•
Re-assemble the plug-in reversed order
