OFF - Turn the battery disconnect switch key counterclockwise in order to shut off the entire electrical system.

The battery disconnect switch and the engine start switch serve different functions. When the battery disconnect switch is turned off, the entire electrical system is disabled. When only the engine start switch is turned off, the battery remains connected to the electrical system.

Turn the battery disconnect switch key to the OFF position and remove the battery disconnect switch key when you service the electrical system or you service any other components of the machine.

Turn the battery disconnect switch key to the OFF position and remove the battery disconnect switch key when the machine is left for an extended period of one month or longer. This procedure will prevent a short circuit from draining the battery. This procedure will also prevent the components from draining the battery. This procedure will also prevent the battery from being drained by vandalism.


NOTICE

Never turn the battery disconnect switch key to OFF with the engine running. Electrical system damage could result.
