12.3) Maintenance Instructions

12.3.1) Engine cleaning

If necessary, clean the engine carefully. If leaks are noticed, they have to be
traced before cleaning. As a principle, clean engine only when cold. Use of
commercially available cold cleaning agent is recommended.
I CAUTION:
Never clean an engine with a high pressure cleaner. This is detrimental for
the electrical installations and the oil seals. Oxidation of the various compo-
nents and failures are the consequence!
After each cleaning procedure blast all electrical components, like battery,
ignition unit, spark plug connector, clamp connections etc. with compressed
air, to prevent leaking current.
I CAUTION:
