INTRODUCTION
Before operating the genset, make sure that this Manual is applicable to the engine type. Refer to the identication
plate if you are not sure about the engine model designation. If you don’t have the correct manual, please contact your
Nanni authorized dealer.
All the information and specications in this manual are based on the technical data available at time of publication.
Changes and updates may be made by Nanni without notice.
Illustrations are intended as a general guide and may vary from the equipment tted in the engine in some details.
If there are any equipment details that are not shown or described in this Manual, or if you have any question regarding
the operation of any equipment, your authorized Nanni dealer will be glad to inform you of correct care and operating
procedures. Contact a NANNI INDUSTRIES S.A.S. authorized dealer for the servicing of your engine. A list of dealers is
available on our website :
www.nannidiesel.com
Read this Manual carefully to learn how to operate and service your engine correctly. Failure to do so could result
in personal injury or equipment damage. This Manual should be considered as a permanent part of the genset and
should remain with it, even when sold.
Right-hand and left-hand sides are determined by standing at the drive or flywheel end (rear) of the engine and facing
toward the front of the engine.
Write engine and generator serial numbers and option codes. Accurately record all numbers. Your Nanni Agent also
needs these numbers when you order parts. File the identication numbers in a secure place. Some engine accesso-
ries such as air cleaner, and instruments are optional. These accessories may be provided by a third party. This Manual
applies only to the engine and those options available through the Nanni distribution network.
