During operation
Always keep your feet on the footboards dur-
ing operation. Otherwise your feet may contact
the rear wheels.
WARNING
Always keep both hands on the handlebars
and both feet on the footboards of your ATV
during operation. Removing even one hand or
foot can reduce your ability to control the ATV
or could cause you to lose your balance and
fall off of the ATV. If you remove a foot from a
footboard, your foot or leg may come into con-
tact with the rear wheels, which could injure
you or cause an accident.
Avoid wheelies and jumping. You may lose
control of the machine or overturn.
WARNING
Never attempt stunts, such as wheelies or
jumps. Don't try to show off.
