EAU01114PRE-OPERATION CHECKS
4-1
The condition of a vehicle is the owner’s responsibility.
Vital components can start to deteriorate quickly and unexpectedly, even if the vehicle remains unused (for example, as a result of ex-
posure to the elements).
Any damage, fluid leakage or loss of tire air pressure could have serious consequences. Therefore, it is very important, in addition to a
thorough visual inspection, to check the following points before each ride.
