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.

Parking on a slope
w
Avoid parking on hills or other inclines.
Parking on a hill or other incline could cause
the ATV to roll out of control, increasing the
chance of an accident. If you must park on
an incline, shift the transmission into the
drive position, apply the parking brake, and
then block the front and rear wheels with
rocks or other objects.
Do not park the ATV at all on hills that are so
steep you could not walk up them easily.
1. Bring the ATV to a stop by applying the
brakes in the drive position.
2. Stop the engine.
3. With the rear brake lever applied, apply the
parking brake and slowly release the brake
lever.

Speed limiter
For riders inexperienced with this model, this
model is equipped with a speed limiter in the
throttle lever housing. The speed limiter limits
the power and top speed of the ATV. Turning
the screw in decreases top speed, and turning it
out increases top speed.
Yamaha recommends that all beginners start off
with the speed limiter turned in to limit the
amount of speed available while they learn. The
limiter may be gradually adjusted to increase
maximum speed as the beginner becomes more
familiar with operating the ATV.

8Keep weight uphill.
8Apply the brakes.
8Lock the parking brake after you are
stopped.
If you begin rolling backwards:
8Keep weight uphill.
8Never apply the rear brake while rolling
backwards. Apply the front brake.
When fully stopped, apply the rear brake
as well, and then lock the parking brake.
Dismount on uphill side or to a side if point-
ed straight uphill. Turn the ATV around and
remount, following the procedure described
in the Owner’s Manual.

adjusted brakes could cause loss of braking
ability, which could lead to an accident.
After servicing:
8Make sure the brakes operate smoothly
and that the free play is correct.
8Make sure the brakes do not drag.
Replacement of brake components requires
professional knowledge. These procedures
should be performed by a Yamaha dealer.
