MAINTENANCE
Shut off the engine before performing any maintenance.
To prevent accidental start-up, turn OFF the engine switch.
The engine should be serviced by an authorized Honda dealer
unless the owner has proper tools and service data and feels
mechanically qualified.
Use only genuine Honda parts or their equivalent. The use of
replacement parts which are not of equivalent quality may
damage the engine.
Periodic inspection and adjustment of the Honda engine is
essential if high level performance is to be maintained. Regular
maintenance will also ensure a long service life. The required
service intervals and the kind of maintenance to be performed are
described on the table below.
