EBU38000FuelMake sure there is sufficient gasoline in the tank
before starting off. Refuel if necessary. (See page
5-20.)EBU19561Engine oilMake sure that the engine oil is at the specified
level. Add oil as necessary. (See page 9-20.)EBU19591Final gear oilMake sure that the final gear oil is at the specified
level. Add oil as necessary. (See page 9-25.)EBU19601Differential gear oilMake sure that the differential gear oil is at the
specified level. Add oil as necessary. (See page
9-27.)EBU19632CoolantMake sure that the coolant is at the specified level.
Add coolant as necessary. (See page 9-29.)
TIPThe coolant level must be checked on a cold en-
gine since the level varies with engine tempera-
ture. EBU29083Front and rear brakesBrake levers and brake pedal
Check that there is no free play in the front and
rear brake levers. If there is free play, have a
Yamaha dealer check the brake system.
 Check for correct free play in the brake pedal. If
the free play is incorrect, adjust it. (See page
9-47.)
 Check the operation of the brake levers and
pedal. They should move smoothly and there
should be a firm feeling when the brakes are ap-
plied. If not, have a Yamaha dealer check the
brake system.
Brake fluid level
Check the brake fluid level. Add fluid if necessary.

on. 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. Completely close the throttle lever, then push the start switch to crank the engine with the
starter. Release the start switch when the en-
gine 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!

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.

WARNING
EWB01502
Dry grass or brush or other combustible ma-
terial accumulated around the engine area
could catch fire. Do not operate, idle, or park
the ATV in dry grass or other dry ground cov-
er. Keep the engine area free of dry grass,
brush, or other combustible material.
 Someone touching the exhaust system dur-
ing or after operation could be burned. Do
not touch the hot exhaust system. Do not
park the ATV in a place where others might
be likely to touch it. The muffler and other engine parts become ex-
tremely hot during operation and remain hot after
the engine has stopped. To reduce the risk of fire
during operation or after leaving the ATV, do not
let brush, grass and other materials collect under
the vehicle, near the muffler or exhaust pipe, or
next to other hot parts. Check under the vehicle
after operating in areas where combustible mate-
rials may have collected. Do not idle or park the
vehicle in long dry grass or other dry ground cov-
er. To prevent burns, avoid touching the exhaust sys-
tem. Park the ATV in a place where pedestrians or
children are not likely to touch it.UBFE60E0.book Page 9 Tuesday, August 18, 2020 10:50 AM

Always check the terrain carefully before you
start down any hill.
 Never operate the ATV on hills too steep for
the ATV or for your abilities. The ATV can
overturn more easily on extremely steep hills
than on level surfaces or small hills.
 Shift your weight backward and to the up
side of the hill.
 Never go down a hill at high speed.
 Avoid going down a hill at an angle that
would cause the ATV to lean sharply to one
side. Go straight down the hill where possi-
ble.
 Improper braking can cause the wheels on
the uphill side to come off the ground or cau-
se loss of traction. Apply brakes gradually. If
in “2WD”, apply only the rear brake.
When riding your ATV downhill, shift your weight
as far to the rear and uphill side of the ATV as pos-
sible. Move back on the seat and sit with your
arms straight. Engine compression will do most of
the braking for you. For maximum engine com-
pression braking effect, select the low-range posi-
tion and change to “4WD” before beginning to
descend the hill. Use caution while descending a hill with loose or
slippery surfaces. Braking ability and traction may
be adversely affected by these surfaces. Improper
braking may also cause a loss of traction.
When this ATV is in “4WD”, all wheels (front and
rear) are interconnected by the drive train. This
means that applying either the front brake or the
rear brake will brake all wheels. When descending
hills, using either brake lever or the brake pedal
will brake the wheels on the downhill side. Avoid
sudden application of either the front or rear brake
because the wheels on the uphill side could come
off the ground. Apply both the front and rear
brakes gradually.
Whenever possible, ride your ATV straight down-
hill. Avoid sharp angles which could allow the ATV
to tip or roll over. Carefully choose your path and
ride no faster than you will be able to react to ob-
stacles which may appear.UBFE60E0.book Page 17 Tuesday, August 18, 2020 10:50 AM
