Page 23: Pre-Operation Checks
EAU01114 PRE-OPERATION CHECKS Owners are personally responsible for their vehicle’s condition. Your scooter’s vital functions can start to deterio- rate quickly and unexpectedly, even if it remains unused (for instance, if it is exposed to the elements). Any dam- age, fluid leak or loss of tire pressure could have serious consequences. Therefore, it is very important that, in addition to a thorough visual inspection, you check the following points before each ride. - Page 24 PRE-OPERATION CHECKS NOTE: Pre-operation checks should be made each time the scooter is used. Such an inspection can be accomplished in a very short time, and the added safety it assures is more than worth the time involved. If any item in the Pre-operation Check is not working properly, have it inspected and repaired before operating the scooter.
