WARNING
EWB02582Inspect cables frequently and replace if
damaged. Corrosion can result when the ca-
ble sheaths become damaged, and cables
can also become frayed or kinked, which
could restrict the operation of controls and
lead to an accident or injury.
Always make sure all control cables work
smoothly before you begin riding in cold
weather. If the control cables are frozen or
do not work smoothly, you could be unable
to control the ATV, which could lead to an
accident or collision. EBU24913Checking and lubricating the front and
rear brake leversThe operation of the front and rear brake levers
should be checked before each ride, and the lever
pivots should be lubricated if necessary. Front brake lever

8To charge the battery
Have a Yamaha dealer charge the battery as soon
as possible if it seems to have discharged. Keep
in mind that the battery tends to discharge more
quickly if the ATV is equipped with optional elec-
trical accessories.
NOTICEECB00932To charge a VRLA (Valve Regulated Lead Acid)
battery, a special (constant-voltage) battery
charger is required. Using a conventional bat-
tery charger will damage the battery. To store the battery
If the ATV will not be used for more than one
month, remove the battery, fully charge it, and
then place it in a cool, dry place.
If the battery will be stored for more than two
months, check it at least once a month and fully
charge it if necessary.NOTICEECB00941Always keep the battery charged. Storing a
discharged battery can cause permanent bat-
tery damage.
To install the batteryTIPBe sure the battery is fully charged. 1. Place the battery in its compartment.
2. Connect the positive battery lead first, then
connect the negative battery lead by installing
their bolt. NOTICE: When installing the bat-
tery, the main switch must be off, and the
positive lead must be connected before
the negative lead.
