●When the engine is running, there is a risk of
injury through:
- turning/hot components
- engines with positive ignition
- ignition systems (high electrical voltage)
You must avoid contact at all times!
●Unauthorized engine modifications will in-
validateanyliability claims against the manu-

have been switched off and the ignition key
has been removed.
Accident prevention guidelines concerning
electrical systems (e.g. VDE-0100/-0101/-
0104/-0105 Electrical protective measures
against dangerous touch voltage) are to be
observed.
When cleaning with fluids, all electrical com-
ponents are to be covered impermeably.
