rear brake lever is applied. However, it is
recommended to shift into neutral before
starting the engine.5. Use the choke lever in reference to the fig-
ure:
Position 1: Cold engine start-
ambient temperature below 30°C.

EBU00181Starting a warm engine
To start a warm engine, refer to the “Starting a
cold engine” section. The choke lever should not
be used. The throttle should be opened slightly.EBU00184Warming up
To get maximum engine life, always warm up
the engine before starting off. Never accelerate
hard with a cold engine! To see whether or not
the engine is warm, check if it responds to the
throttle normally with the choke lever turned off.

1. Lean towards inside of turn.
2. Support your weight on the outer footrest.1. Se pencher vers l’intérieur du virage.
2. S’appuyer sur le repose-pied externe.1. Inclínese hacia el interior del giro.
2. Descanse su peso en el descansapie externo.

As you approach a curve, slow down and begin
to turn the handlebars in the desired direction.
As you do so, put your weight on the footboard
to the outside of the turn (opposite your desired
direction) and lean your upper body into the
turn. Use the throttle to maintain an even speed
through the turn. This maneuver will let the
wheel on the inside of the turn slip slightly,
allowing the ATV to make the turn properly.
This procedure should be practiced at slow
speed many times in a large off-road area with
no obstacles. If an incorrect technique is used,
your ATV may continue to go straight. If the ATV
doesn’t turn, come to a stop and then practice
the procedure again. If the riding surface is slip-
pery or loose, it may help to position more of
your weight over the front wheels by moving for-
ward on the seat.
Once you have learned this technique you
should be able to perform it at higher speeds or
in tighter curves.

CROSSING A SLOPE
Traversing a sloping surface on your ATV
requires you to properly position your weight to
maintain proper balance. Be sure that you have
learned the basic riding skills on flat ground
before attempting to cross a sloping surface.
Avoid slopes with slippery surfaces or rough ter-
rain that may upset your balance.
As you travel across a slope, lean your body in
the uphill direction. It may be necessary to cor-
rect the steering when riding on loose surfaces
by pointing the front wheels slightly uphill. When
riding on slopes be sure not to make sharp turns
either up or down hill.
