OPERATING INSTRUCTIONS

4.1 Safety precautions for operation of diesel engine

Before the engine is started, the operator must understand the operating method;

master the working principle of diesel engine and understand its power limit.

During starting and running of engine, lack of experience and careless operation

may cause fatal accident. However, if the operator has mastered the operating

technique and understood the power limit in advance, and is carefully operating,

then the personal injury caused by accident can be completely avoided.

4.2 General instructions

Proper attention and care of engine will ensure optimum performance, long life and

more economical operations.

• Follow daily maintenance as per the guidelines.

• Ensure all meter and gauges are in operational conditions.

• Running the engine on idle speed must be limited to 3~4 minutes. Idling the

engine for longer periods will cause carbon to clog injector spray holes and

piston rings.

• Do not operate the engine with low engine body temperature for longer period.

If the engine temperature becomes too low (≤60˚C), raw fuel will dilute with the

lubricant. Fuel mixed lubricant could not provide proper lubrication between the

moving components. It is also harmful for the internal sub-assemblies.

4.3 Preparation for rst start

To avoid personal injury or machine damage, clear the loose

material away from the engine vicinity before starting

When preparing to start a new or overhauled engine, perform all the operations

listed below. Failure to follow these instructions may result in serious engine

damage. The operator must be familiar with all the instruments, gauges, and

controls which are needed to operate the engine. Understand the locations and

function of the following: Oil pressure indicator, low oil pressure warning indicator,

coolant temperature indicator, high coolant temperature warning indicator etc.

Closely monitor the overall engine performance and if any abnormal sign like

excessive blow by, overheat, excessive consumption of fuel or lube oil, abnormal

vibration or noise, change in exhaust gas color etc. is noticed, turn off the engine

immediately and rectify the cause of trouble. Engine damage may be avoided by a

quick response to early indications of troubles.

System-wise checks

Carry out a system-wise check to avoid any mistakes or points left out before

the rst start of the engine.
