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
tractor 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.
