EBU24901
Checking and lubricating the cables
The operation and the condition of all control ca-
bles should be checked before each ride, and the
cables and cable ends should be lubricated if nec-
essary. If a cable is damaged or does not move
smoothly, have a Yamaha dealer check or replace
it.
WARNING

EWB02581

Inspect cables frequently and replace if dam-
aged. Corrosion can result when the cable
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 coldweather. If the control cables are frozen or do
not work smoothly, you could be unable to
control the ATV, which could lead to an acci-
dent or collision.

Battery
A poorly maintained battery will corrode and dis-
charge quickly. The electrolyte level, battery lead
connections and breather hose routing should be
checked before each ride and at the intervals
specified in the periodic maintenance and lubrica-
tion chart.
To check the electrolyte level
1. Place the ATV on a level surface.
2. Check the electrolyte level in the battery.TIP

The electrolyte should be between the minimum
and maximum level marks.
3. If the electrolyte is at or below the minimum
level mark, add distilled water to raise it to the
maximum level mark.
NOTICE:
Use only dis-
tilled water, as tap water contains minerals
that are harmful to the battery.

Batteries produce explosive gases. Keep
sparks, flame, cigarettes or other sources of ig-
nition away. Ventilate when charging or using
in an enclosed space.
KEEP OUT OF REACH OF CHILDREN.
4. Check and, if necessary, tighten the battery
lead connections and correct the breather
hose routing.
To store the battery
If the ATV will not be used for more than one
month, the battery will need to be removed and
stored as follows.
1. Disconnect the negative lead first and then the
positive lead.
NOTICE:

trolyte at least once a month and fully charge
the battery whenever necessary.
To install the battery
TIP

Be sure the battery is fully charged.
1. Install the battery.
2. Connect the positive lead first, and then con-
