parking the ATV, 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.
WARNING

EWB00220

Always set the parking brake before starting
the engine. The ATV could start moving un-
expectedly if the parking brake is not ap-
plied. This could cause loss of control or a
collision.

Always be sure you have released the park-
ing brake before you begin to ride. The brake
could overheat if you ride the ATV without re-
leasing the parking brake. You could lose
braking performance which could cause an

TIP

If knocking or pinging occurs, use a different brand
of gasoline or higher octane grade.
NOTICE

ECB00070
Use only unleaded gasoline. The use of leaded
gasoline will cause severe damage to internal
engine parts, such as the valves and piston
rings, as well as to the exhaust system.
WARNING

EWB00310

Do not overfill the fuel tank. Fuel expands
when it heats up. If the fuel tank is overfilled,
fuel could spill out due to heat from the en-
gine or the sun.

Be careful not to spill fuel, especially on the
engine or exhaust pipe which can cause a
fire and severe injury. Wipe up any spilled
fuel immediately.

Do not refuel right after the engine has been
running and is still very hot.

Be sure the fuel tank cap is closed securely.

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.
EBU20682
Engine break-in
TIP


For ATVs equipped with an odometer or an hour
meter, follow the figures given in km (mi) or thefigures 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.
0–160 km (0–100 mi) or 0–10 hours
Avoid prolonged operation above 1/2 throttle. Vary
the speed of the ATV regularly. Do not operate it at
one set throttle position.
160–320 km (100–200 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.

Parking
When parking the ATV, stop the engine, shift the
drive select lever into the forward position, apply
the parking brake, and then turn the fuel cock to
“OFF”.
EBU20740
Parking on a slope
WARNING
EWB00830
Avoid parking on hills or other inclines. Park-
ing 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, place the ATV transversely across the
incline, shift the drive select lever to the for-
ward position, stop the engine, apply the park-
ing 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 forward position.
2. Stop the engine.
3. With the rear brake applied, apply the parking
brake.

loaded ATV can be unstable.

If you are carrying cargo and towing a trailer, in-
clude the tongue weight in the maximum ATV
load limit.

Load cargo on the carriers as close to the center
of the ATV as possible. Put cargo at the rear of
the front carrier, at the front of the rear carrier,
and center it.

Tie down cargo securely to the carriers. Make
sure cargo in the trailer cannot move around. A
shifting load can cause an accident.

Make sure the load does not interfere with con-
trols or your ability to see where you are going.

Ride more slowly than you would without a load.
The more weight you carry, the slower you
should go.

Allow more braking distance. A heavier ATVtakes longer to stop.

Avoid making sharp turns unless at very slow
speeds.

Avoid hills and rough terrain. Choose terrain
carefully. Added weight affects the stability and
handling of the ATV.WARNING
EWB00820
Never exceed the stated load capacity for this
ATV. Overloading this ATV or carrying or tow-
ing cargo improperly could cause changes in
ATV handling which could lead to an accident.
Cargo should be properly distributed and se-
curely attached. Reduce speed when carrying
cargo or pulling a trailer. Allow greater dis-
tance for braking.
MAXIMUM LOADING LIMIT
ATV loading limit (total weight of rider, cargo,
accessories, and tongue):
105.0 kg (231 lb)
Front carrier:
5.0 kg (11 lb)
Rear carrier:
10.0 kg (22 lb)

GETTING TO KNOW YOUR ATV
This ATV is for recreation and utility use. This sec-
tion, Riding your ATV, provides general ATV riding
instructions for recreational riding. The skills and
techniques described in this section, however, are
appropriate for all types of riding. Riding your ATV
requires special skills acquired through practice
over a period of time. Take the time to learn the ba-
sic techniques well before attempting more difficult
maneuvers.
Riding your new ATV can be a very enjoyable ac-
tivity, providing you with hours of pleasure. But it is
essential to familiarize yourself with the operation
of the ATV to achieve the skill necessary to enjoy
riding safely. Before you begin to ride, be sure you
have read this Owner’s Manual completely and un-
derstand the operation of the controls. Pay partic-
ular attention to the safety information on pages
1-1–1-4. Please also read all caution and warning
labels on your ATV.
RIDE WITH CARE AND GOOD JUDGEMENT
Get training if you are inexperienced.
Beginners should get training from a certified in-
structor.
Become familiar with this ATV at slow speeds first,
even if you are an experienced operator. Do not at-
tempt to operate at maximum performance until
you are totally familiar with the ATV’s handling and
performance characteristics.
WARNING

EWB01380
Never operate this ATV without proper instruc-
tion. Beginning and inexperienced operators
should regularly practice the skills and the op-
erating techniques described in this Owner’s
Manual. The risk of an accident is greatly in-
creased if the operator does not know how to
operate the ATV properly in different situations
and on different types of terrain.
Riding your ATV requires skills acquired
through practice over a period of time.
Take the time to learn the basic techniques well
before attempting more difficult maneuvers.
