2. INTENDED USE
2.1. Pre-operation of the Diesel Engine
When preparing the new diesel engine for operation, perform its depreservation. To do
this, remove the protective shrouds and plugs mounted on the engine. Check and adjust, if neces-
sary, the fan belt tension. Fill all the refill tanks with working oils, fuel and coolant (the refill tank
capacities, description and marks of the fluids are given in Appendix A). Fill the fuel-feeding sys-
tem with fuel and purge this system to remove air from there.
For performing the maintenance and eliminating faults, an individual complete set of
spare parts, tools and accessories (their schedule is given in Appendix B) is enclosed to each die-
sel engine.

Use
2.2.1.1. General Guidelines
To ensure the long-term and trouble-free operation of the diesel engine follow the main
guidelines stated below:
- check regularly the condition of fastening the assembly units and, if necessary, retighten
the fasteners;
- before starting the engine check the level of oil in the engine crankcase and coolant in
the radiator;
- after starting the engine let it run first at the minimum idling speed for 2-3 min with in-
creasing gradually this speed up to its maximum value prior to engaging the load;
- load the engine only after the cooling system fluid has warmed up to plus 40C;
- prior to putting the diesel engine into operation under load, perform its running-in fol-
lowing Section 2.2.1.5;
- idling of the diesel engine for more than 15 minutes is not recommended;
- do not overload the diesel, during the operation monitor the readings of the instru-
ments;
- do not stop the engine by shutting the intake path by the emergency shutter except for
the emergency cases;
- perform the maintenance of the diesel engine in proper time following the guidelines of
Section 3;
- use only the fuel and oil of the marks specified in this Manual;
- maintain the engine clean, do not allow any leakage of fuel, oil and coolant or suction
of non-cleaned air into the cylinders;
- the diesel can be operated at the longitudinal and lateral tilts not exceeding 20.
To avoid disturbances in the operating process when running the engine at the altitude of
more than 4,918 ft (1,500 m) above sea level, adjust the fuel pump to reduce its capacity in ac-
cordance with Table 2.
