8If 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 rec-
ommended until you have corrected the slide.
(See pages 7-71 ~ 7-73.)
8If your ATV can’t make it up a hill you are try-
ing to climb:
Turn the ATV around if you still have forward
speed. If not, stop, dismount on the uphill side
of the ATV and physically turn the ATV
around. If the ATV starts to slip backwards
DO NOT USE THE REAR BRAKE - the ATV
may tip over on top of you. Dismount the ATV
on the uphill side. (See pages 7-45 ~ 7-55.)

8If your ATV is traversing a sloping surface:
Be sure to ride with your weight positioned
towards the uphill side of the ATV to maintain
proper balance. If the ATV starts to tip, steer
down the hill (if there are no obstacles in your
way) to regain balance. If you discover that
the ATV is going to tip over, dismount on the
uphill side. (See pages 7-61 ~ 7-63.)
8If your ATV encounters shallow water:
Ride slowly and carefully through slow mov-
ing water, watching for obstacles. Be sure to
let water drain from the ATV and CHECK
YOUR BRAKES FOR PROPER OPERATION
when you come out of the water. Do not con-
tinue to ride your ATV until you have regained
adequate braking ability. (See pages 7-65 ~
7-67.)

NOTE:8Recommended brake fluid: DOT 4
8Brake fluid replacement:
1. When disassembling the master cylinder or caliper cylinder, replace the brake fluid. Normally
check the brake fluid level and add the fluid as required.
2. On the inner parts of the master cylinder and caliper cylinder, replace the oil seals every two
years.
3. Replace the brake hoses every four years, or if cracked or damaged.

EBU00309Front and rear brake pad inspection
Each brake pad is provided with a wear indica-
tor. The indicators allow checking of brake pad
wear without disassembling the brake. Apply the
brake and inspect the wear indicators. If they
are ALMOST in contact with the disc plate, ask
a Yamaha dealer to replace the pads.

EBU00755Brake fluid level inspection
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 necessary.
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 fluid.
Otherwise, the rubber seals may deterio-
rate, causing leakage and poor brake per-
formance.

3. Refill with the same type of brake fluid.
Mixing fluids may result in a harmful chem-
ical reaction and lead to poor brake perfor-
mance.
4. Be careful that water does not enter the
master cylinder when refilling. Water will
significantly lower the boiling point of the
fluid and may result in vapor lock.
5. Brake fluid may deteriorate painted sur-
faces or plastic parts. Always clean up
spilled fluid immediately.
6. Have a Yamaha dealer check the cause if
the brake fluid level goes down.

EBU00752*Brake fluid replacement
1. Complete fluid replacement should be
done only by trained Yamaha service per-
sonnel.
2. Have a Yamaha dealer replace the follow-
ing components during periodic mainte-
nance or when they are damaged or leak-
ing.
8Replace all rubber seals every two years.
8Replace all hoses every four years.
