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.

Servicing the Battery

Service Interval: Every 25 hours—Check the
electrolyte level. (If the machine is
in storage, check it every 30 days.)
Important:
Before welding on the machine,
disconnect the negative cable from the battery to
prevent damage to the electrical system.
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
will discharge 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.
1. Open the battery cover on the side of the shroud
(Figure 85).
Note:
Press down on the flat surface above the
battery cover to ease the removal of the cover
(Figure 85).
