remains in good status, we can filter the lubricant much better by change the oil filter.
• Change fuel filter, clean or change first stage fuel filter core, oil water separator’s core (some
of the generator sets have), check and organize fuel pipes arrangement.
• The change interval of above fuel filter (core) depends on the quality of fuel (if it contains
many impurity), the fuel adding method is reasonable or not, the fuel tank is cleaned periodica-
lly or not (contaminant discharge). Once the color of engine exhaust air is found to be abnormal
and the output power decrease, first the fuel system needs to be checked.
For each 400 hours of running
• Check and adjust the transmission belt and change it when necessary
• Check and clean radiator core
• Discharge deposit in the fuel tank
For each 800 hours of running
• Check if the turbocharger has leakage
• Check if the air inlet pipes has leakage
For each 1200 hours of running
• Adjust valve clearance
For each 2000 hours of running or at least 24 months
• Change air filter (depend on ambient air quality, decide if this need to be changed earlier)
• Change coolant and coolant filter (some generator sets have)
• Thoroughly clean radiator core and water path
For each 2400 hours of running
• Check fuel injector
• Thoroughly check and clean turbo‐charger
• Comprehensively check engine equipment

Alternator
Inside and outside of the alternator shall be cleaned periodically. And the frequency of cleaning
depends on the generator set’s ambient environment. When the cleaning becomes necessary,
following procedures can be followed: cut off all of the powers, wipe off the dirt, contaminant,
oil stain, water or any other liquid from the surface. The ventilation mesh also needs to be
cleaned. The adhesiveness of these materials to the coils will cause the coils overheat or
damage the insulation.
The dirt and contaminant need to be absorbed by dust collector. Please don’t use air blow or
