USE OF GENUINE PARTS

harmonized. To prevent engine faults in advance and use
engines with best performance for a long period,
maintenance and replacement of expendable parts
should be conducted regularly.
Use of genuine parts is recommended. Using
unauthorized or remanufactured parts may cause critical
