ƔContact between electrolyte and skin or eyes must be prevented when replenishing it for the battery, because
electrolyte is an acid. In case of skin contact, please flush the contacted part with soap and clean water; in case of
eyes contact, flush your eyes for 15 minutes with clean water and seek for medical treatment immediately.
ƔCool the engine first to avoid being hurt by coolant steam when filling coolant. Open the pressure cap only when the
coolant is lower than 50ć, and then slowly loosen the cap to release the pressure of coolant.
ƔWipe up lubricating oil, fuel, Coolant or other liquids overflowed. Put oily rags into a fire-protection container, but not
leave it on the engine.
ƔBefore starting the engine after being repaired, make sure to be ready to cut air supply. In case of any abnormal, cut
air supply to stop the engine immediately.
ƔDo not rotate the engine with the fan, otherwise severe personal injury or damage to fan blades can be caused.
ƔDo not touch by hand the intake and exhaust system components such as the exhaust manifold, turbocharger,
intercooler air inlet pipe, expand tank because they are in high temperature when the engine is in operation.
ƔRelease the pressure in the air system, lubricating system, cooling system or fuel system prior to dismantling or
loosening any pipelines, permanent joints, connectors or relevant parts of these systems. Do not check leakage with
hand, otherwise high pressure and high temperature fuel, lubricating oil and coolant can cause personal injury.
ƔIf the engine will not be used for a long time or is under repair, separate it from the battery to prevent an unexpected
start-up. Meanwhile, place a sign STOP in the operation room or on the controller.
ƔUsed lubricating oil may contain carcinogenic substance which can result in reproductive toxicity, therefore,
inhalation of or longtime exposure to oil steam should be avoided. Waste oil should be disposed in proper, safe and
reliable manner.
ƔTo prevent choke or cold injury, removal of air-conditioning refrigerant (Freon) pipeline should be conducted in
well ventilated environment with protective clothing worn. For environment protection, the refrigerating system
should be emptied or filled using dedicated equipment so as to prevent diffusion of Freon into atmosphere.
Refrigerant should be recovered and recycled.
1.4 Engine Operation Instructions
ƔRead this manual carefully, and be in strict accordance with operation instructions and maintenance procedure
specified in this manual.
ƔConduct daily and 4-levele maintenance as specified in this manual, and keep the records of scheduled
maintenance.
ƔUse the proper fuel, lubricating oil and coolant specified in this manual.
ƔWhen filling lubricating oil, it is not allowed to use the mixture of different-graded oil.
ƔThe coolant specified in this manual should be used for the engine cooling system at any kind of climate.
Ɣ60 hours’ running-in must be conducted for a new or overhauled engine. Please refer to Section 3.7 for the
running-in requirements.
ƔDo not start the engine without air filter, otherwise, early engine wear will be caused.
ƔPreparations should be well done before starting the engine. Be sure to remember that the engine must be started
without load.
ƔCheck if coolant, lubricating oil and fuel are enough before starting the engine. It is not allowed to start the engine
with lack of diesel fuel in the fuel tank. The fuel tank should be replenished; or it will cause damage to the high
pressure fuel pump.
ƔObserve the engine operation and all the instrument readings. In case of critical situation, an emergency stop should
be performed to prevent the seizure of moving parts caused by low oil pressure or overheating due to lack of coolant.
ƔDo not run the engine at high load and high speed when the coolant temperature is blow 60ć.
