b High pressure fuel spray can cause irreversible body damage. Wear required protection when conducting operations on the entire circuit. b Make sure that the lines are depressurised before any dismantling operations. b Release the high pressure before handling the feed and injection circuit of a HPCR engine. b When checking the injectors, make sure that the high pressure jet does not touch the skin. b All investigations of leaking fuel, oil or other high pressure liquids must be conducted using a screen and never with bare hands. b Use a spray fumes extracting device. b If fuel comes into contact with the skin, it can cause injury. Consult a doctor immediately. b Fuel, oil and coolant contain harmful chemicals. Avoid any contact with skin and hands; do not ingest. The use of gloves and safety goggles is highly recommended.

b Do not touch the hot parts of an engine in operation or which has just stopped. b Do not touch an engine in operation. b Let the engine cool down before carrying out any maintenance operation. b Release the pressure on the greasing, fuel and cooling circuits before disconnecting or removing hoses or associated parts. b At operating temperature, the coolant is hot and pressurised. When pressure is released sharply, this burninghot liquid may be transformed into fumes. b Any contact with this burning-hot liquid or these fumes may cause serious burns. b Let the components of the coolant circuit cool down before draining the circuit. b Only check the coolant level when the engine has stopped. b F-#?-3)'/0$"%?)+,%)2)--%")!-':)+#)"%-%.0%)!"%00'"%B b Hot oil can cause injury.

Safety Instructions Electrical risks Isolation checks must be carried out regularly. The electrical circuit of the engine must be isolated from the engine and boat earth. Isolation problems can cause short-circuits or stray current. Stray current can damage bushing or crankshaft seating and may also cause radio-frequency disturbance. The engine earth must be properly connected to the boat %."+,).0)?%--).0).--)+,%)8%>1;-%),#0%0)1/)+,%)$##-./+)./&)@'%-) circuits.

Consult Technical Documentation DT 21.GO3 Cathodic Protection



Risks associated with the power generator It is strictly prohibited to commission an alternator, new or otherwise, if the isolation is less than 1 Mohm for the stator and 100,000 ohms for the other windings.

D800 - Engine wintering



SAFETY WARNING Users should carefully read the safety instructions before installing and operating the engine. If the engine is not going to be used for a certain time during the year, proceed with the engine wintering process. Please take all precautions against frost. DT 03.G01



Engine cooling circuit b Check the condition of hoses and collars. Replace them if required. b Make sure that the coolant contained in the engine complies with the S. I. Moteurs Baudouin!"#$%&'%()&*+"! listed in DT 03.G01 and protected against frost.



Raw water cooling circuit b Close the raw water suction valve. b Thoroughly drain the raw water cooling circuit.



Draining the raw water pump b Unscrew the drain plug to drain the pump. b Do not replace the drain plug until engine start-up. b If it is not possible to thoroughly drain all low points of the %&,%-&).!,$#/(%$!)0$!1,(&+!#/-2"!(+1!,$'//!)0$!%&,%-&)!3,*4!(!0&20! point with the recommended coolant suitable for the geographical location (see DT 03.G01).

Engine oil circuit



Non-contractual illustrations



b Before wintering, drain the used oil and replace it using an identical product. b Oil cartridges will be replaced when the engine is brought back into service.



Depending on the equipment



00361 - Edition 02 - December 11



b Pre-lubricate the engine. b Turn over the engine using starter with the "STOP" button pressed, until the needle on the oil pressure dipstick reaches 1 bar. To pre-lubricate a main or auxiliary generator which is not equipped with a pre-greasing system, please refer to the S. I. Moteurs Baudouin approved network.
