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.

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

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.
