Never allow the temperature of the coolant at the outlet from the engine, the temperature and pressure of oil to exceed recommended values.

Maintain the level of oil in the sump and governor above the lower mark on the oil gauge or sight glass.

Give particular attention to the level of oil in the sump and governor when the engine is hound to operate under the conditions of protracted list or trim.

Inspect the joints between engine units as well as those in the cooling, lubricating and fuel system for minor leaks in the form of droplets, which are likely to occur when the engine is in running condition, and eliminate the defect by tightening the relevant nuts or bolts or by replacing the defective gasket during the next servicing of the engine.… READ THE REST

Diesel engine. Preparing for maiden starting

Remove the coat of rust preventer from the engine.

Make sure the engine is well secured to the bedframe and properly coupled to the driven machine.

Make sure all the auxiliaries are mounted on the engine in a secure way.

Disconnect the load.

Fill the fuel tank with fuel of the grade specified for the given ambient temperature. Open the fuel shut-off cock and hand-prime the fuel system so as to enable trapped air to escape through the bleed screws provided in the filter and fuel pump.

Fill the sump with oil, pouring same through the breather, so that the oil level is at the top mark on the oil level gauge.

Fill the governor with oil so that its level is at the top mark on the glass of the level gauge; fill the pump with oil so that its level is at the check hole.… READ THE REST

Safe Working with Diesel Engine. Safety rules

Authorized to attend to the diesel engine are only those persons who have received special training, have been briefed on safety rules and have passed a test confirming their knowledge of the fundamentals of engineering and of this publication.

Never touch any rotating part of the engine by hand or tool and never repair the engine in running condition.

Never use open fire as a source of light while filling the engine with fuel or oil; eliminate any leak of fuel or oil without delay.

Use portable low-voltage lamps (not above 36 V) for lighting purposes.

Install the engine in a clean, well lighted and ventilated engine room wherein a fire extinguisher is provided; keep the engine room tidy.

Never keep inflammables in close proximity to the exhaust pipe.

Hoist the engine with the aid of lifting fixture only.
