Servicing the Battery

WARNING
CALIFORNIA
Proposition 65 Warning
Battery posts, terminals, and related
accessories contain lead and lead
compounds, chemicals known to
the State of California to cause
cancer and reproductive harm. Wash
hands after handling.
DANGER
Battery electrolyte contains sulfuric acid
which is a deadly poison and causes severe
burns.
• Do not drink electrolyte and avoid contact
with skin, eyes, or clothing. Wear safety
glasses to shield your eyes and rubber
gloves to protect your hands.
• Fill the battery where clean water is always
available for flushing the skin.
WARNING
Charging the battery produces gasses that
can explode.
Never smoke near the battery and keep sparks
and flames away from it.
WARNING
Battery terminals or metal tools could short
against metal tractor components causing
sparks. Sparks can cause the battery gasses
to explode, resulting in personal injury.
• When removing or installing the battery,
do not allow the battery terminals to touch
any metal parts of the machine.
• Do not allow metal tools to short between
the battery terminals and metal parts of the
machine.
WARNING
Incorrect battery cable routing could damage
the machine and cables causing sparks.
Sparks can cause the battery gasses to
explode, resulting in personal injury.
• Always disconnect the negative (black)
battery cable before disconnecting the
positive (red) cable.
• Always connect the positive (red) battery
cable before connecting the negative
(black) cable.
Check the battery condition weekly or after every
50 hours of operation. Keep the terminals and the
entire battery case clean because a dirty battery will
discharge slowly. To clean the battery, wash the
entire case with a solution of baking soda and water.
Rinse it with clear water. Coat the battery posts and
cable connectors with Grafo 112X (skin-over) grease
(Toro Part No. 505-47) or petroleum jelly to prevent
corrosion.
