Brake fluid leakage
Check to see if any brake fluid is leaking out of the
pipe joints or brake fluid reservoirs. Apply the
brakes firmly for one minute. If a lever moves slow-
ly inward, there may be a leak in the brake system.
If there is any leakage, the brake system should be
checked by a Yamaha dealer.
Brake operation
Test the brakes at slow speed after starting out to
make sure they are working properly. If the brakes
do not provide proper braking performance, check
the brake pads for wear. (See page 8-47.)
EBU19761Throttle lever Check the operation of the throttle lever. It must
open smoothly and spring back to the idle position
when released. Have a Yamaha dealer correct if
necessary.
EBU19814Tires Check tire pressure regularly to make sure it is at
the recommended specifications. Also check for
wear and damage.
Tire pressure
Use the low-pressure tire gauge to check and ad-
just tire pressures when the tires are cold. Tire
pressures must be equal on both sides.
WARNING! Operation of this vehicle with im- proper tire pressure may cause severe injury
or death from loss of control or rollover. Tire
pressure below the minimum specified could
also cause the tire to dislodge from the rim un-
der severe riding conditions.
[EWB02541]
Set tire
pressures to the following specifications:
Specified brake fluid:
DOT 4

5The low-pressure tire gauge is included as stan-
dard equipment. Make two measurements of the
tire pressure and use the second reading. Dust or
dirt in the gauge could cause the first reading to be
incorrect. Tire wear limit
When the tire groove decreases to 3 mm (0.12 in)
due to wear, replace the tire.
Recommended tire pressure:
Fro nt35.0 kPa (0.350 kgf/cm², 5.0 psi)
Rear 30.0 kPa (0.300 kgf/cm², 4.4 psi)
Minimum tire pressure: Fro nt32.0 kPa (0.320 kgf/cm², 4.6 psi)
Rear 27.0 kPa (0.270 kgf/cm², 4.0 psi)
Maximum tire seating pressure: Fro nt250 kPa (2.5 kgf/cm², 36 psi)
Rear 250 kPa (2.5 kgf/cm², 36 psi)

or park position before starting the engine.3. Apply the rear brake lever or brake pedal.
4. Completely close the throttle lever and startthe engine by pushing the start switch.TIPIf the engine fails to start, release the start switch,
then push it again. Pause a few seconds before
the next attempt. Each cranking should be as short
as possible to preserve battery energy. Do not
crank the engine more than 10 seconds on each
attempt.NOTICEECB00163For maximum engine life, never accelerate
hard when the engine is cold!
EBU20441Operating the drive select lever and
driving in reverse NOTICEECB00170Before shifting, stop the ATV, otherwise the
transmission may be damaged.Shifting: Neutral to High-range and High-range
to Low-range1. Bring the ATV to a complete stop.
2. Apply the brake pedal, and then shift by mov- ing the drive select lever along the shift guide.TIPMake sure that the drive select lever is completely
shifted into position.

3. Release the brake pedal, and then open the throttle lever gradually.
Shifting: Neutral to Reverse and Reverse to
Park
WARNING
EWB00720Improper operation in reverse could make you
hit an obstacle or even a person behind you,
resulting in serious injury. When you shift into reverse, make sure there are no people or ob-
stacles behind you. When it is safe to proceed,
go slowly.
1. Bring the ATV to a complete stop.
2. Apply the brake pedal. The drive select lever
cannot be shifted into or from reverse or park

TIP●When in reverse, the reverse indicator light
should come on. If the indicator light does not
come on, have a Yamaha dealer check the elec-
trical circuit.●Due to the synchronizing mechanism in the en-
gine, the indicator light may not come on until the
ATV starts moving.
4. Check behind for people or obstacles, andthen release the brake pedal.
5. Open the throttle lever gradually and continue to watch to the rear while backing.EBU20682Engine break-in TIP●For ATVs equipped with an odometer or an hour
meter, follow the figures given in km (mi) or the
figures given in hours.●For ATVs not equipped with an odometer or
hour meter, follow the figures given in hours.There is never a more important period in the life of
your engine than the first 320 km (200 mi) or 20
hours of riding. For this reason, you should read
the following material carefully.
Since the engine is brand new, do not put an ex-
cessive load on it for the first 320 km (200 mi) or 20
hours. The various parts in the engine wear and
polish themselves to the correct operating clear-
ances. During this period, prolonged full-throttle
operation or any condition that might result in en-
gine overheating must be avoided.
