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.

Throttle lever
Once the engine is running, movement of the
throttle lever will increase the engine speed.
Regulate the speed of the machine by varying
the throttle position. Because the throttle is
spring-loaded, the machine will decelerate, and
the engine will return to an idle any time the
hand is removed from the throttle lever.
Before starting the engine, check the throttle to
be sure it is operating smoothly. Make sure it
returns to the idle position as soon as the lever
is released.
w
Malfunction of the throttle could make it diffi-
cult to speed up or slow down when you
need to. This could cause an accident.
Check the operation of the throttle lever
before you start the engine. If the throttle
does not work smoothly, check for the
cause. Correct the problem before riding the
ATV or consult a Yamaha dealer.

Speed limiter
The speed limiter keeps the throttle from fully
opening, even when the throttle lever is pushed
to the maximum. Screwing in the adjuster limits
the maximum engine power available and
decreases the maximum speed of the ATV.
Your ATV was delivered with an adjustable
speed limiter. Yamaha recommends that all
beginners start off with the speed limiter screw
turned in to limit the amount of speed available
while they learn. The limiter screw may be grad-
ually turned out to increase maximum speed as
the beginner becomes more familiar with operat-
ing the ATV.

Parking brake
Use the parking brake when you have to start
the engine or park the machine, especially on a
slope. Apply the rear brake lever and push down
the lock plate to apply the parking brake.
Squeeze the rear brake lever to release the
parking brake.
w
8Always set the parking brake before start-
ing the engine. The ATV could start mov-
ing unexpectedly if the parking brake is
not applied. This could cause loss of con-
trol or a collision.
8Always be sure you have released the
parking brake before you begin to ride.
The brake could overheat if you ride the
ATV without releasing the parking brake.
You could lose braking performance
which could cause an accident. You could
also wear out the brakes prematurely.

Fuel cock
The fuel cock supplies fuel from the fuel tank to
the carburetor.
The fuel cock has three positions.
OFF: With the lever in this position fuel will not
flow. Always turn the lever to this position
when the engine is not running.
ON: With the lever in this position, fuel flows
to the carburetor. Normal riding is done
with the lever in this position.
RES: This indicates reserve. If you run out of
fuel while riding, turn the lever to this
position. THEN FILL THE FUEL TANK
AT THE FIRST OPPORTUNITY. After
refuelling, return the fuel cock lever to the
“ON” position.
