3.1.1
Electric system
Formation of a rust film on the permanent magnets in the magneto ring
and on the metal cores of the trigger coils is harmless.
Replace attachment screws and lock washers if there is heavy
oxidation or rust formation.
Before reassembly clean all contact surfaces of the screws removed
and apply LITHIUM grease. Take care that no foreign objects fall into
the magneto ring. Clean ring terminals and apply LITHIUM grease to
the contact surfaces to assure lasting contact.
Check contact between electrical contacts and ground connections
(ring terminals) by removal, if necessary apply contact spray to
increase conductivity.
3.2)
Checking the ignition unit, trouble shooting
Components can only be replaced but not repaired. If there is no ignition spark,
systematically trace possible causes.
