5.3 FIRST PERIOD OF USE

During the first period of yacht operation, beyond the normal maintenance operations indicated in this Manual, we recommend carrying out the following additional operations and more accurate checks.
The duration of this period varies according to the frequency and use modes, but are in any case suitable to allow a correct run-in of all systems and components on board.

WARNING

We recommend consulting the technical documentation provided by the Manufactures of the various on-board systems and components; they can indicate operations, checks and specific times not included in this section of the Manual.

Following the first period of use, the hereunder listed additional operations and checks, should be performed at longer time intervals, although in any case, they play an important role for the safeguarding and reliability of the yacht and navigation safety.

• After starting each engine, check for the correct circulation of the cooling water inside the circuit, by verifying that it comes out of the drains. Check also for the presence of leaks from the sea cock valves and strainers of the cooling circuits.ì
• Before the engines start, check the correct tension of the v-belts.
• Check the possible presence of unusual noises from the engines exhaust.
• Before and after navigation, check for possible leaks in the shaft lines.
• During navigation monitor constantly the temperatures and operation pressures of the devices on board (propulsion engines, generators, gear boxes).
• Check, by means of indicators installed on the electrical panel of main helm station, the correct load condition of the batteries starting the engines and utilities. Moreover, the engine alternators must correctly charge the batteries.
• Check the efficiency of the rudders (by often checking the tiller angle) and of the interceptors.
• Before and after navigation, check the correct level of oil in the following systems: steering system, interceptors, hydraulic gangway, bow/stern thruster, etc..
• After the generator to start, wait several minutes before loading it. Bring it slowly to maximum performance monitoring its correct operation.
• Check the correct load level of all extinguishers (fixed and portable ones) installed on board.
• Before and after navigation, check the correct operation of all bilge pumps on board.
• Check tightness and closure of portholes and hatches.
• Check the correct sliding and closure of the back wall, considering that it is not watertight.
