Operator Service

Maintenance The good functioning and the efficiency of the mechanical components mainly depend on a constant and correct maintenance.

TAKING VISION OF THE ENTIRE MANUAL allows to properly perform the operations of ordinary and extraordinary maintenance. The lack of the recommended operations can compromise the lifetime and the integrity of the transmission and bring to failure or injury to the operator. In the event of breakdown or anomaly, the prompt reaction from the specialized personnel will guarantee a higher lifetime of the assembly, preventing further damage in the years. GENERAL SAFETY RECOMMENDATIONS IMPORTANT:

Before starting any operation, read this paragraph carefully.

Safety precautions The correct use and the correct repair of the assembly and its components are very important for security and reliability. The recommended procedures, that are listed on this service manual, have been tested as operative ways to act. Strictly follow each procedure making use both of writings and illustrations. Some of these procedures show the usage of pertinent tools designed to perform every operation clearly and correctly. Some specific tools must be used, where necessary, to perform some proper operations. It is impossible to manage every working procedure or all the possible methods with their own risks, therefore whoever uses not recommended tools must be aware that the safety of the operator and the boat will be endangered.

PERFORMED CORRECTLY

Repair The procedure for assembly / disassembly of the transmission allows to perform the complete overhaul of the group and is assisted with photos, for a complete and safe guide for each operation. It is assumed that the transmission has been removed from the vessel. The deep knowledge of the assembly allows the correct estimate of the kind of procedure to be followed, which may only require the disassemble of a few components, operating on a part of the transmission only.
