cancer and reproductive harm. Wash
hands after handling.
Checking the Battery
Condition
Service Interval: Every 50 hours
Important:
Before welding on the machine,
disconnect the negative cable from the battery to
prevent damage to the electrical system. Also,
you must disconnect the engine, InfoCenter,
and machine controllers before welding on the
machine.
Note:
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.
