CROSSING THROUGH SHALLOW WATER
The ATV can be used to cross slow moving,
shallow water of up to a maximum of 35 cm in
depth. Before entering the water, choose your
path carefully. Enter where there is no sharp
drop off, and avoid rocks or other obstacles
which may be slippery or upset the ATV. Drive
slowly and carefully.
WARNING
Never operate this ATV in fast flowing water
or in water deeper than that specified in your
Owner’s 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. If the ATV is operated through deep or
fast flowing water, the tires may float, causing
loss of traction and loss of control, whichcould lead to an accident.

Test your brakes after leaving the water. Do
not continue to ride your ATV without verifying
that you have regained proper braking ability.CAUTION:After riding your ATV in water, be sure to
drain the trapped water by removing the
check hose at the bottom of the air filter case.
Wash the ATV in fresh water if it has been op-erated in salt water or muddy conditions.

SLIDING AND SKIDDING
Care should be used when riding on loose or
slippery surfaces since the ATV may slide. If
unexpected and uncorrected, sliding could
lead to an accident.
To reduce the tendency for the front wheels to
slide in loose or slippery conditions, position-
ing your weight over the front wheels will
sometimes help.
If the rear wheels of your ATV start to slide
sideways, control can usually be regained (if
there is room to do so) by steering in the direc-
tion of the slide. Applying the brakes or accel-
erating is not recommended until you have
corrected the slide.

WHAT TO DO IF...
This section is designed to be a reference
guide only. Be sure to read each section on
riding techniques completely.
WHAT TO DO...l
If your ATV doesn’t turn when you want it
to:
Bring the ATV to a stop and practice the
turning maneuvers again. Be sure you are
putting your weight on the footboard to the
outside of the turn. Position your weight
over the front wheels for better control.
(See pages 7-39 ~ 7-43.)
l
If your ATV begins to tip while turning:
Lean more into the turn to regain balance. If
necessary, gradually let off the throttle
and/or steer to the outside of the turn. (See
pages 7-39 ~ 7-43.)
l
If your ATV starts to slide sideways:
Steer in the direction of the slide if you have
the room.
Applying the brakes or accelerating is not
recommended until you have corrected the
slide. (See pages 7-69 ~ 7-71.)

l
If your ATV encounters shallow water:
Ride slowly and carefully through slow
moving water, watching for obstacles. Be
sure to let water drain from the ATV and
CHECK YOUR BRAKES FOR PROPER OPER-
ATION when you come out of the water. Do
not continue to ride your ATV until you have
regained adequate braking ability. (See
pages 7-63 ~ 7-65.)

Inspecting the brake fluid level
Insufficient brake fluid may let air enter the
brake system, possibly causing the brakes to
become ineffective.
Before riding, check that the brake fluid is
above the lower level and replenish when nec-
essary.
Observe these precautions:
1. When checking the fluid level, make sure
the top of the master cylinder is level by
turning the handlebars.
2. Use only the designated quality brake flu-
id. Otherwise, the rubber seals may dete-
riorate, causing leakage and poor brake
performance.NOTE:If DOT 4 is not available, DOT 3 can be used.Recommended brake fluid: DOT 4

Front brake lever free play adjustment
The front brake lever free play should be 4 ~
8 mm. If the free play is incorrect, adjust it as
follows.
1. Loosen the locknut.
2. Turn the adjusting bolt so that the brake
lever movement is 4 ~ 8 mm before the
adjusting bolt contacts the master cylin-
der piston.
3. Tighten the locknut.
WARNING
Operating with improperly serviced or adjust-
ed brakes could cause loss of braking ability,
which could lead to an accident.
After servicing:l
Make sure the brakes operate smoothly
and that the free play is correct.
l
Make sure the brakes do not drag.
l
Make sure the brakes are not spongy. All
air must be bled from the brake system.
Replacement of brake components requires
professional knowledge. These procedures
should be performed by a Yamaha dealer.

WARNING
Operating with improperly adjusted brakes
could cause the brakes to malfunction result-
ing in reduced braking performance. This
could increase the chance of a collision or acci-
dent. After adjusting the parking brake, block
the rear of the machine off the ground and
spin the rear wheels. Check to make sure there
is no brake drag. If brake drag is noticed, per-form the adjustment again.
