Maintenance intervals for competition use
The following schedule is intended as a general guide to maintenance and lubrication. Bear in mind that such factors
as weather, terrain, geographical location, and individual usage will alter the required maintenance and lubrication
intervals. If you are a doubt as to what intervals to follow in maintaining and lubricating your machine, consult your
FANTIC dealer.
Periodic inspection is essential in making full use of the machine performance. The service life of the parts varies
substantially according to the environment in which the machine runs (e.g., rain, dirt, etc.). Therefore, earlier inspection
is required by reference to the list below.
Items marked with an asterisk (*) should be performed by a FANTIC dealer as they require special tools, data and technical
skills.
