Revision Programs
The engine warranty is conditioned to the accomplishment of the first revision (50 hours), and more revisions mentioned
in the Warranty Certificate.
All the operations of the obligatory and periodic revisions must be performed by our dealers and / or Authorized Service
Network according to the instructions in this Manual.
The installation of optional, unoriginal aftermarket parts will cancel warranty and may cause serious damages to the engine,
with consequent decreasing of its life duration. This procedure only will be allowed if genuine parts with normal versions of
factory are used.
For a better performance of your engine, always use genuine spare parts and equipments according to the factory
versions.
