Maintenance
4.1
General outline
For different types of generator sets, users need to
refer to the matched engine’s operation and
maintenance manual to implement correct
maintenance operation.
In order to obtain maximum operation safety and life
expectancy of the generator sets, periodic
maintenance is very important. Strictly observance of
the terms on generator set’s maintenance can ensure
generator set’s performance and reduce its damage
to environment.
Correctly identify and strictly observe the labels
(drawings, words and warnings etc.) On diesel
generator sets can be of great help to correct
maintenance and safe operations.
Maintenance of the generator sets shall be made
when it has been stopped and the cable which
connect to the negative polar of the battery shall be
dis ‐ connected so that to ensure the generator set will
not mistakenly start.

Engine
Each time before start the engine
! Check lubricant oil level
! Check coolant level
! Check air filter indicator
! Check the ventilation of radiator and ambient
environment
! Check engine’s transmission belt
! Check fuel supply status
Generator sets which run frequently need to be
checked one time every 6 to 8 hours. Backup
generator sets need to be checked once more after
being stopped.
Depends on the new generator set’s running status,
when it is necessary, within 100 to 300 Hours,
following actions shall be taken:
! Check the valve clearance
! Check the fuel injector
For each 0~50 hours of running
! Discharge the water remained in the oil ‐ water
separator
! Check the battery’s electrolyte level (except
maintenance free battery)
For each 50~600 hours of running or at least each 12
months
! Change lubricant and lubricant filter
! Because the quality of lubricant oil, sulfur content of
the fuel, and lubricant consumption rate of each
engine is different, the interval for lubricant oil
change for each generator set will be different. When
change the lubricant oil, at the same time oil filter
needs to be changed, otherwise the change of oil will
become meaningless. On the contrary, if the lubricant
oil 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 periodically 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
