Foreword
Dear Customer,
Air / liquid-cooled Deutz engines are designed
for a large number of applications. Conse-
quently, a wide range of variants is offered to
meet the requirements of specific cases.
Your engine is appropriately equipped for the
installation concerned, which means that not
all of the components described in this Opera-
tion Manual are necessarily mounted to your
engine.
We have endeavoured to highlight any differ-
ences 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,
DEUTZ AG

ductive harm.
Care and Maintenance
Sound care and maintenance practices will ensure
that the engine continues to meet the requirements
placed on it. Recommended service intervals must
be observed and service and maintenance work
carried out conscientiously.
Special care should be taken under abnormally
