CAUTION
Always keep the battery char-
ged. Storing a discharged bat-
tery can cause permanent bat-
tery damage.
To charge a sealed-type (MF)
battery, a special (constant-
voltage) battery charger is
required. Using a conventional
battery charger will damage
the battery. If you do not have
access to a sealed-type (MF)
battery charger, have a Yamaha
dealer charge your battery.

2. Remove the blown fuse, and then install a new fuse of the specified
amperage.

CAUTION
Do not use a fuse of a higher ampe-
rage rating than recommended to
avoid causing extensive damage to
the electrical system and possibly a
fire.

WARNING
Do not remove the radiator cap when the engine and radiator are hot. Scalding hot fluid and steam may be
blown out under pressure, which could cause serious injury. Be sure to wait until the engine has cooled.
After removing the radiator cap retaining bolt, place a thick rag, like a towel, over the radiator cap, and then
slowly rotate the cap counterclockwise to the detent to allow any residual pressure to escape. When the his-
sing sound has stopped, press down on the cap while turning it counterclockwise, and then remove the cap.
