condition
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.
Important:
Before welding on the machine,
disconnect the negative cable from the battery to
prevent damage to the electrical system. Also,
disconnect the engine and machine controllers
before welding on the machine.
Note:
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
discharges slowly. To clean the battery, wash the
entire case with a solution of baking soda and water.
Rinse 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.
WARNING
Exposure to battery acid or a battery
explosion can cause serious personal injury.
Before you service a battery, wear face
protection, protective gloves, and protective
clothing.

A battery contains sulfuric acid, which can
cause serious burns; and they can produce
explosive gases.

WARNING
If you try to charge or jump start a frozen
battery, it could be explosive, causing
personal injury to you or others in the area.
To prevent the battery electrolyte from
freezing, keep the battery fully charged.
