● Please read and observe the information
given in this Operation Manual. This will
enable you to avoid accidents, preserve the
manufacturer’s warranty and maintain the
engine in peak operating condition.
● This engine has been built exclusively for
the application specified in the scope of
supply, as described by the equipment manufacturer and is to be used only for the
intended purpose. Any use exceeding that
scope is considered to be contrary to the
intended purpose. The manufacturer will
not assume responsibility for any damage
resulting therefrom. The risks involved are
to be borne solely by the user.
● Use in accordance with the intended purpose also implies compliance with the conditions laid down by the manufacturer for
operation, maintenance and servicing. The
engine should only be operated by personnel trained in its use and the hazards involved.
● The relevant accident prevention guidelines
and other generally accepted safety and
industrial hygiene regulations must be observed.
● 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 invalidate any liability claims against the manufacturer for resultant damage.
Manipulations of the injection and regulating
system may also influence the performance
of the engine, and its emissions. Adherence
to legislation on pollution cannot be guaranteed under such conditions.
● Do not change, convert or adjust the cooling
air intake area to the blower.
The manufacturer shall not be held responsible for any damage which results from
such work.
● When carrying out maintenance/repair operations on the engine, the use of DEUTZ
original parts is prescribed. These are specially designed for your engine and guarantee perfect operation.
Non-compliance results in the expiry of the
warranty!
● Maintenance and cleaning of the engine
should only be carried out when the engine
is switched off and has cooled down.
You must ensure that the electrical systems
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 components are to be covered impermeably.

installation concerned, which means that not
all of the components described in this Operation Manual are necessarily mounted to your
engine.
We have endeavoured to highlight any differences so that you will be able to locate theses
differences relevant to your engine.
Please read this Manual before starting your
engine, and always observe the operating and
maintenance instructions.
We are available to help with any additional
inquiries
Sincerely,
