INTRODUCTORY SAFETY MESSAGE TO PARENTS
AN ATV IS NOT A TOY AND CAN BE HAZARDOUS TOOPERATE. An ATV handles
differently from other vehicles including motorcycles and cars. A collision or rollover
can occur quickly, even during routine maneuvers such as turning and driving on hills
or over obstacles, if you fail to take proper precautions.
Children differ in skills, physical abilities, and judgement. Some children may not be
able to operate an ATV safely. Parents should supervise their child’s use of the ATV
at all times. Parents should permit continued use only if they determine that the child
has the ability and maturity to operate the ATV safely.
Failure to follow the warnings contained in this manual can result in
SERIOUS INJURY or DEATH.
• Read this manual and all labels carefully and follow the operating procedures described.
• Never operate an ATV without proper instruction. Take a training course. Riders
should receive training from a certified instructor. Contact an authorized Polaris
ATV dealer or call Polaris at 1-800-342-3764 to find out about the training courses
nearest you.
iii
• Always follow the age guidelines for your machine. Youth ATVs are designed and
intended for use by children in two age groups. The Scrambler 50 is for children
not less than 6 years of age. The Scrambler 90 and the Sportsman 90 are for children not less than 12 years of age. No children under the age of 16 should ride an

PRE RIDE CHECK
You are almost ready to have an adultstart your ATV. Before the ATV is started
for the first time,you must do a PRE-RIDE CHECK. In fact, every time you ride
your ATV you must have an adult help you check these things before starting
it. Let’s learn about these things now.
Make sure the throttle doesn’t stick. Check thisby pushing the lever toward
the handlebar and then letting go. The lever should come right back to where
it was before you pushed it. If it comes back slowly or stays open, you have
a sticky throttle. This means that something is wrong or broken.
If you have a sticky throttle, do not start the engine. You could get hurt if
you ride when you have a stickythrottle. Have anadult or your PolarisDealer fix the throttle.
R--12
PRE RIDE CHECK
Make sure the brakes don’t stick. Check the brake levers b y squeezing
them toward the handlebar and then letting it go. They should come right back
to where they were before you squeezed. Ifthey go back slowly or stay on,your
brakes are sticking.
If you have sticky brakes, do not start the engine. You could get hurt if you
ride when you have sticky brakes. Have an adult or your Polaris Dealer fix
the sticky brakes.
If you have used the storage area under the seat, make sure the seat is
locked and in place.
R--13
PRE RIDE CHECK
Have an adult check the gas level to see if your ATVneeds more. Children
should never add their own gasoline. This should always be done by an
adult. Before anyone adds gasoline to your ATV they must read the
instructions and warnings on page 60 in this Owner’s Manual.
Always have an adult put gas in your machine.
Have an adult check the engine oil level when the engineiscold. The engine
is very hot after it has been running. It could burn you. Children should never
check the oilon their own. An adult shouldbe in charge of keeping the gas and
oil levels to the full marks.
R--14
PRE RIDE CHECK
This last check is done with the engine running. You must check to make
certain that ALL THREE WAYS TO STOP your ATV are working the way they
should. Do you remember what they are? If you cannot list them, go back to
page R--10 and review.
