(Это доступно только для экспертов.)
Обслуживание Класса II должно быть добавлено к следующим пунктам помимо тех, что находятся в процессе обслуживания Класса I..
1. Промойте поршень с тормозом., the rocker set, piston and ring set, double bearing and examine the state of wearing and tearing.
2. Examine the rolling big end bearing and check inside and outside of them if they are loose.
3. Clarify the dirt or mud in the pipes of the coolant system.
4. Clarify the accumulated coal in the burning room of the cover gasket and in the exhausting pipelines.
5. Examine the state of wearing and tearing about the valve, valve pipelines and valve stand, push the rod and the rocker and then grind and regulate them.
6. Wash and examine the oil pump, oil cooler and their pipelines.
7. Examine the producing valve of the oil spraying cylinder plug complete set.
8. Examine and regulate the state of oil-sprayer, oil spraying pressure and atomizer.
9. Clarify the accumulated coal in the turbocharger rotor, and examine the state of wearing and tearing about the bearing and impeller. Если необходимо, repair or change it.
10. Examine if the connector bolt of the generator and diesel engine is loose or tooth-slip. If something problem, repair or change it.

Breakdown phenomenon/ Causes to the breakdown and settlements/ Failed to start / An attempted start/ Low or unsteady rotational speed/ Low voltage frequency or zero indication/ Additional installation without operation/ Non-transmission genset/ Low oil pressure/ Water temperature/ Hypervelocity (Over speed)/ Low oil level/ Battery warning/ Engine smoking/Different sounds from engine/ Causes/ Settlements
1) Abnormal circuit operation/ examine the electric causes or contact FDK Co.
2) Inadequate battery power/ examine and charge the battery, change it when necessary.
3) Battery joint is rotten or cable connector is loose./ Examine the connecting role which connects the cable, twist the nut tight and change the connectors and nuts which are rotten heavily.

11) Over low ambient humidity/ Examine the oil viscosity and brand.
12) Abnormal governor/ Contact FDK Co. and ask for help.
13) Breakdown from the start circuit of control system/ Examine the starter of control system and stop the control circuit.
14) Low ambient humidity or under preheated engine/ Examine the engine‟s preheating system, operate the engine no load and make it reach the operation temperature.
15) Abnormal operation of AVR/DVR/ Contact FDK Co. and ask for help.
16) Over low hypervelocity of engine/ Examine the engine governor.
17) Breakdown from the indicating meters/ Examine the meters, change them when necessary.
18) Breakdown from the meters connection/ Examine backtrack of the meters‟ connection.
19) Overload/ Lower the load of genset.
20) Overload and tripping operation/ Lower the load of genset and survey if the ambient humidity is over height or not.
21) Short circuit or overload causes tripping operation/ Examine the genset exit installation and its backtrack.
22) Abnormal operation of additional installation/ Contact FDK Co. and ask for help.
23) Vanished power source/ Examine the power backtrack.
