Page 10: Transportation
Chapter Five Marine engine Operation Engine transportation When the diesel engine is transported, should lift the engine by engine hooks . Moving the engine, pay more attention to avoid damage the engine appearance , accessories , oil pipes , panel , etc . When long distance transportation is necessary, the air filter and silencer should be dismantled, use plugs and plastics to seal the air intake and exhaust hole , water pump inlet and outlet hole , fuel inlet and outlet hole . -

should have bigger bendy semi diameter, to avoid big pressure of exhaust and reduce engine output. 5. Inlet pipe of the seawater should on the lowest position of the ship cabin, and should install a filter to avoid absorb impurity. Inlet pipe should with check valve, to avoid inundation from seawater . - Page 12 Fuel oil The diesel engine should use following specification oil according form 1: form 1 fuel oil specification Fuel oil specification GB252 light diesel oil Above 0 ℃ －10℃～－20℃ Atmospheric temperature 0℃～－10℃ －10＃ －20＃ Diesel oil brand 0＃ ● Please clear the fuel oil for at least 72 hours before filling it into the fuel tank , then Pick up the top clean fuel oil.

3. Turn the starting switch to the“starting position ” , after the crankshaft is speeded up by the starting motor , the engine is started then . 4. Please note: Each starting no more than 10 seconds to protect the motor and battery. If start continually, the interval time should be more than 2 mins. -
Page 15: Stopping
Stopping 1. Before stopping the engine, unload first, decrease the engine to the idle speed gradually, also cut off the clutch system. When the water temperature falls down below 70℃, operate the stop handle to stop to stop the engine. 2. - Page 16 New engine adjusting period principle From the experience, new engine life , working stability and economical mainly depends on previous adjusting period . Thus user should operate the engine under new engine adjusting principle. Number Load Running time Note During adjusting period, fuel valve should Idle load 20 mins at full open position, load can be estimated...
- Page 17 6.Marine engine ‘s technology maintenance In order to work well and reliability for diesel engine, keep better technique capability, reduce abrasion of spare parts, extend the engine life, the users must carry out following maintenance rule carefully and regularly. Diesel engine maintenance criterion: 1.daily maintenance(carry through Each class) 2.Top of technology maintenance(carry through After working 100hours in Total) 3.
- Page 18 technology maintenance items Top of 1. Carry out all of daily maintenance items 2. Replace oil in oil sump and cleanout oil sump and collection oil pump and scree assembly. 3. Cleanout or replace oil filter. 4. Cleanout fuel filter or replace new filters after working 200hours in total 5.
- Page 19 7. Checked working instance for thermostat and leaking instance for hole for releasing water. If leaking is serious, should be replace water seal. 8. Check and see if electric equipment and wires connection is fitted and if lead touching is well. In case burnt, must be clean up and replaced. 9.
