Refill with the same type of brake fluid. Mixing
fluids may result in a harmful chemical reaction
and lead to poor brake performance.
Be careful that water does not enter the brake
fluid reservoir when refilling. Water will signifi-
cantly lower the boiling point of the fluid and
may result in vapor lock.
Brake fluid may deteriorate painted surfaces or
plastic parts. Always clean up spilled fluid im-
mediately.
Have a Yamaha dealer check the cause if the
brake fluid level goes down.

Battery
This machine is equipped with a sealed-type bat-
tery. Therefore it is not necessary to check the
electrolyte or add distilled water in the battery. If
the battery seems to have discharged, consult a
Yamaha dealer.CAUTION:
Do not try to remove the sealing caps of the
battery cells. You may damage the battery.

WARNING
Battery electrolyte is poisonous and danger-
ous, causing severe burns, etc. It contains sul-
furic acid. Avoid contact with skin, eyes or
clothing.
Antidote:
EXTERNAL: Flush with water.
lNTERNAL: Drink large quantities of water
or milk. Follow with milk of magnesia, beat-
en egg or vegetable oil. Call a physician
immediately.
EYES: Flush with water for 15 minutes and
get prompt medical attention.
Batteries produce explosive gases. Keep
sparks, flame, cigarettes or other sources of
ignition away. Ventilate when charging or us-
ing in an enclosed space. Always shield your
eyes when working near batteries.
KEEP OUT OF REACH OF CHILDREN.

Troubleshooting
Although Yamaha machines receive a rigid in-
spection before shipment from the factory, trouble
may occur during operation.
Any problem in the fuel, compression, or ignition
systems can cause poor starting and loss of pow-
er. The troubleshooting chart describes a quick,
easy procedure for making checks. If your ma-
chine requires any repair, take it to a Yamaha
dealer.
The skilled technicians at a Yamaha dealership
have the tools, experience, and know-how to prop-
erly service your machine. Use only genuine
Yamaha parts on your machine. Imitation parts
may look like Yamaha parts, but they are often in-
ferior. Consequently, they have a shorter service
life and can lead to expensive repair bills.
WARNING
Do not smoke when checking the fuel system.
Fuel can ignite or explode, causing severe in-
jury or property damage. Make sure there are
no open flames or sparks in the area, including
pilot lights from water heaters or furnaces.
