WARNING
EWB00162Always stop the ATV before changing from
two-wheel drive to four-wheel drive and vice-
versa. The ATV handles differently in two-
wheel drive than in four-wheel drive in some
circumstances. Changing from two-wheel
drive to four-wheel drive or vice versa while
moving may cause the ATV to unexpectedly
handle differently. This could distract the oper-
ator and increase the risk of losing control andof causing an accident.
EBU18280Throttle lever Once the engine is running, movement of the throt-
tle lever will increase the engine speed.
Regulate the speed of the ATV by varying the
throttle position. Because the throttle is spring-
loaded, the ATV will decelerate, and the engine will
return to an idle any time the hand is removed from
the throttle lever.
Before starting the engine, check the throttle to be
sure it is operating smoothly. Make sure it returns
to the idle position as soon as the lever is released.

7 If your ATV has stalled or stopped and you believe
you can continue up the hill, restart carefully to
make sure you do not lift the front wheels which
could cause you to lose control. If you are unable
to continue up the hill, dismount the ATV on the up-
hill side. Physically turn the ATV around and then
descend the hill.
If you start to roll backwards, DO NOT apply either
brake abruptly. If you are in 2WD, apply only the
front brake. If you are in 4WD, because all wheels
are interconnected by the drive train, applying ei-
ther brake will brake all wheels, therefore, avoid
sudden application of either the front or rear brake
as the wheels on the uphill side could come off theground. The ATV could easily tip over backwards.
Apply both the front and rear brakes gradually, or
dismount the ATV immediately on the uphill side.
WARNING
EWB01811Maintain a steady speed when climbing a hill.
If you lose all forward speed:
Keep weight uphill.
Apply the brakes.
Shift to the park position after you are
stopped.
If you begin rolling backwards:
Keep weight uphill.
2WD: Never apply the rear brake while rolling
backwards. Apply the front brake. When fully
stopped, shift to the park position.
4WD: Apply both front and rear brakes grad-
ually. When fully stopped, shift to the park
position.
Dismount on uphill side or to a side if pointed
straight uphill. Turn the ATV around and re-
mount, following the procedure described inthe Owner’s Manual.

7RIDING DOWNHILL
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 compres-
sion braking effect, change to 4WD before begin-
ning to descend the hill. Improper braking may
cause a loss of traction.
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 sud-
den application of either the front or rear brake be-
cause 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.
WARNING
EWB01620Always follow proper procedures for going
down hills as described in this Owner’s Manu-
al.
Note: a special technique is required when
braking as you go down a hill.
Always check the terrain carefully before
you start down any hill.
Shift your weight backward.
Never go down a hill at high speed.
