1. Regular maintenance schedule
○——Check, correction, adjustment
×——Replacement
Note:
a. When operating in dusty or polluted environments, it is necessary to increase the frequency of
maintenance.
b. If the engine power drops, there is any black smoke or the engine noise becomes louder before
maintenance is due, inspections and checks should be carried out and the opening pressure of
the diesel nozzle and fuel atomization state should be adjusted if necessary.
c. Replace the engine lubricating oil at the first 100h and then every 250 hours thereafter. For
common-rail engines, the maintenance cycle may be shortened as appropriate. (For details,
please refer to the Engine Maintenance Manual).
