IMPORTANT INFORMATION 8
Use definition
The vehicle is designed and constructed to withstand the usual demands of regular traffic and use on gentle terrain (unpaved roads), but
not for use on race tracks.
Info
The ATV is authorized for public road traffic in the homologous version only.
Maintenance
A prerequisite for trouble-free operation and prevention of wear is that the engine and chassis maintenance and adjustment work described
in the owner's manual are properly carried out. Poor adjustment and tuning of the engine and chassis can lead to damage and breakage of
components.
Using the vehicle in extreme conditions such as very muddy or wet roads can lead to above-average wear of components such as the trans-
mission train or the brakes. For this reason, it may be necessary to service or replace worn parts before the limit specified in the service
schedule is reached.
Pay careful attention to the prescribed running-in period, inspection and maintenance intervals. If you observe these exactly, you will
ensure a much longer service life for your vehicle.
Fuel, oils, etc.
You should use the fuels, oils and greases according to specifications as listed in the owner's manual.
Spare parts, accessories
For your own safety, only use spare parts and accessories that have been approved and/or recommended by KTM and have them installed
by an authorized KTM workshop. KTM accepts no liability for other products and any resulting damage or loss.
Certain spare parts and accessories are specified in parentheses in the descriptions. Your KTM dealer will be glad to advise you.
