Honda SH300 Owner's Manual page 37

NOTE
The first oil change is at 1000 km (600
miles), but in this case the indicator should
not be reset. The indicator will appear after
the scooter has covered approximately
6000 km (4000 miles for the type E).
Therefore, after the second engine oil
change as prescribed by the maintenance
table (page 81) remember to reset the oil
change indicator (page 24).
