technique described in this manual on level
ground. Avoid crossing the side of a steep hill if
possible.
 Always use proper procedures if you stall or roll
backwards when climbing a hill. To avoid stall-
ing, use the proper gear range and maintain a
steady speed when climbing a hill. If you stall or
roll backwards, follow the special procedure for
braking described in this manual. Dismount on
the uphill side or to a side if pointed straight up-
hill. Turn the ATV around and remount, following
the procedure described in this manual.
 Always check for obstacles before operating in
a new area.
 Never attempt to operate over large obstacles,
such as large rocks or fallen trees. Always follow
proper procedures when operating over obsta-
cles as described in this manual.
 Always be careful when skidding or sliding.
Learn to safely control skidding or sliding by
practicing at low speeds and on level, smooth
terrain. On extremely slippery surfaces, such as
ice, go slowly and be very cautious in order to
reduce the chance of skidding or sliding out of
control. 
Never operate an ATV in fast flowing water or in
water deeper than that recommended in this
manual. Remember that wet brakes may have
reduced stopping ability. Test your brakes after
leaving water. If necessary, apply them several
times to let friction dry out the linings.
 Always be sure there are no obstacles or people
behind you when you operate in reverse. When
it is safe to proceed in reverse, go slowly.
 Always use the size and type of tires specified in
this manual.
 Always maintain proper tire pressure as de-
scribed in this manual.
 Never exceed the stated load capacity for an
ATV. Cargo should be properly distributed and
securely attached. Reduce speed and follow in-
structions in this manual for carrying cargo or
pulling a trailer. Allow greater distance for brak-
ing.
 Do not operate your ATV during darkness un-
less it is equipped with a properly functioning
headlight. Off-road riding is inherently danger-
ous and additionally, off-road trails do not have
streetlights to guide you.

EBU19902Read the Owner’s Manual carefully before riding
the ATV. If there is a control or function you do not
understand, ask your Yamaha dealer.
WARNING
EWB00632Read the Owner’s Manual carefully to become
familiar with all controls in order to help pre-
vent any loss of control, which could cause an
accident or injury. EBU30564Starting the engineThis model is equipped with an ignition circuit cut-
off system. To enable starting one of the following
conditions must be met:
The drive select lever is in the neutral or park po-
sition.
 The rear brake lever or brake pedal is applied.TIPIt is recommended to shift into neutral or park and
apply the rear brake when starting the engine.
NOTICEECB00151See the “Engine break-in” section on page 7-4
prior to operating the engine for the first time. To start the engine
1. Turn the key to “ ” (on) and the engine stop switch to “ ” (run).
The coolant temperature warning light and
the engine trouble warning light should
come on for a few seconds, then go off.
 For EPS-equipped models, the electric
power steering warning light should come
on and stay on until the engine is started.NOTICEECB00826To avoid possible damage, do not operate the
ATV if a warning light does not work as de-
scribed above. 2. Apply the brake pedal, then shift the drive se-
lect lever into the neutral or park position. The
corresponding indicator light should come

7on. If the indicator light does not come on,
have a Yamaha dealer check the electrical
circuit.
3. Apply the rear brake lever or brake pedal.
4. Release the throttle lever, then push the start switch to crank the engine with the starter.
Release the start switch when the engine has
started.
TIPIf the engine fails to start, release the start switch.
Wait a few seconds before the next cranking at-
tempt to allow battery voltage to restore. Do not
crank the engine more than 10 seconds on any
single attempt. NOTICEECB00164For maximum engine life, never accelerate
hard when the engine is cold!
EBU36230Operating the drive select lever and
driving in reverseNOTICEECB03330Do not shift without coming to a complete stop
and waiting for the engine to return to normal
idle speed. Damage to the engine or drivetrain
may occur. 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.

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, and
then release the brake pedal.
5. Open the throttle lever gradually and continue to watch to the rear while backing.EBU36861Engine break-inThere is never a more important period in the life
of your engine than the first 240 km (150 mi) or 20
hours of operation. For this reason, you should fol-
low the engine break-in instructions carefully.
Since the engine is brand new, do not put an ex-
cessive load on it for the first 240 km (150 mi) or
20 hours. During this period the various parts in
the engine wear and polish themselves to the cor-
rect operating clearances. Avoid prolonged full-
throttle operation or any condition that might re-
sult in engine overheating. 0–120 km (0–75 mi) or 0–10 hours
Avoid prolonged operation above 1/2 throttle.
Vary the speed of the ATV regularly. Do not oper-
ate it at one set throttle position.
120–240 km (75–150 mi) or 10–20 hours
Avoid prolonged operation above 3/4 throttle. Rev
the engine freely, but do not use full throttle at any
time.
240 km (150 mi) or 20 hours and beyond
The ATV can now be operated normally.
NOTICEECB00221If any engine trouble should occur during the
engine break-in period, immediately have a
Yamaha dealer check the ATV. EBU27322ParkingWhen parking the ATV, stop the engine, and shift
the drive select lever into the park position.
