6. Add Mobil Fluid 424 until lubricant level is up to hole

in clutch. Clutch should be approximately 1/3 full.

7. Install check plug.

Note: Do not use engine oil (i.e. 10W30) in bidirectional
clutch. Anti–wear and extreme pressure additives will
cause undesirable clutch performance.

Servicing the Battery

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.

Warning

Important

 

Before welding on the machine, disconnect

ground cable from the battery to prevent damage to the
electrical system.

Note: Check battery condition weekly or after every 50
hours of operation. Keep terminals and entire battery case
clean because a dirty battery will discharge slowly. To clean
the battery, wash the entire case with 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.
