BATTERY BREATHER HOSE ROUTING
YAMAHA Battery
Check the level of the battery electrolyte and make sure
that the terminals are tight. Add distilled water if the
electrolyte level is low.
1. When inspecting the battery, make sure that the
battery breather pipe routing is correct. If the
breather pipe touches painted parts, or if its end is
in such a position that may cause gas or electrolyte
leakage, it may cause structural or esthetic
damages to the motorcycle.
2. Take care not to spill battery fluid on the chain.
Battery fluid may weaken the chain causing shorter
chain life and possibly result in an accident.

Battery electrolyte is poisonous and dangerous,
causing severe burns, etc. It contains sulfuric acid.
Avoid contact with skin, eyes or clothing.
Antidote:
EXTERNAL: Flush with water.
INTERNAL: Drink large quantities of water or milk.
Follow with milk of magnesia, beaten 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,
cigarrettes, etc., away. Ventilate when charging or using
it in an enclosed space. Always shield your eyes when
working near batteries.
KEEP OUT OF REACH OF CHILDREN.
A poorly maintained battery will corrode and discharge
quickly. The battery fluid should be checked at least once
a month.
The level should be between the minimum and maximum
marks. Use only ìdistilled waterî if refilling is necessary.
Normal tap water contains minerals which are harmful
to a battery; therefore, refill only with “distilled water”. Replenishing the battery fluid

WARNING:

Storage the battery
1. When the motorcycle is not used for a month or longer,
remove the battery and store it in a cool, dark place.
Completely recharge the battery before reinstallation.
2. If the baterry needs to be stored for a longer period
than the period mentioned above, check the specific
gravity at least once a month, and recharge it when the
specific gravity is below normal.
3. Always make sure the connections are correct when
reinstalling the battery. The red (positive) lead is for the
+ terminal and the black (negative) lead is for the -
terminal. Always connect the red (positive) lead first,
then connect the black (negative) lead. Make sure that
the battery breather pipe is correctly routed, free of
obstructions, and in good condition.

If a fuse is blown, turn off the ignition switch and the switch
of the circuit in question. Install a new fuse of proper
amperage. Turn on the switches and see if the electrical
device operates. If the fuse immediately blows again,
consult a Yamaha dealer.
WARNING:
Do not use fuses of higher amperage rating than those
recommended. Substitution of a fuse of improper rating
can cause extensive electrical system damage and
possibly a fire.
