dangerous, causing severe burns,
etc. It contains sulfuric acid. Avoid
contact with skin, eyes or clothing.

month or longer, be sure to remove the
battery, fully charge it and store it in a
cool, dry place.
EC000102
CAUTION:@ l
Completely recharge the bat-
tery before storing. Storing a
discharged battery can cause
permanent battery damage.

Use a battery charger designed
for a sealed-type (MF) battery.
Using a conventional battery
charger will cause battery dam-
age. If you do not have a sealed-
type battery charger, contact
your Yamaha dealer.

Supporting the motorcycleSince the Yamaha YZF-R6 has no cen-
terstand, follow these precautions
when removing the front and rear
wheel or performing other mainte-
nance requiring the motorcycle to
stand upright. Check that the motor-
cycle is in a stable and level position
before starting any maintenance. A
strong wooden box can be placed un-
der the engine for added stability.
Front wheel service
To stabilize the rear of the motorcycle,
either use a motorcycle stand or place
a motorcycle jack under the frame in
front of the rear wheel to prevent it from
moving from side to side. Then use a
motorcycle stand to elevate the front
wheel off of the ground.Rear wheel service
Use a motorcycle stand or motorcycle
jack to elevate the motorcycle so the
rear wheel is off the ground. Alterna-
tively, two jacks can be placed under
the frame or swingarm.
