Should the ATV be separated from the parent by
a distance longer than the lanyard length, the
lanyard will pull out the clip and stop the engine.
For further explanation of this switch and the
lanyard, see “TEACHING YOUR CHILD TO
OPERATE THE ATV” in the “SAFETY INFOR-
MATION” section.
NOTE:
8The engine cannot be started with the clip
removed.
8When your child has developed sufficient skill
to no longer need you to follow with the lan-
yard, the lanyard can be stowed under the
seat of the ATV. However, you must still
closely supervise your child at all times during
ATV operation.
