Illustration 1g00406959


ON - Insert the key. Turn the key clockwise in order to activate the electrical system. The battery disconnect switch must be on before starting the engine.


OFF - Turn the key counterclockwise in order to shut off the electrical system.

The battery disconnect switch serves a different function from the engine start switch. 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.

When you are servicing the electrical system or other components on the machine, turn the battery disconnect switch to OFF and remove the key.

When you are leaving the machine for a week or for a longer period, turn the battery disconnect switch key to OFF and remove the key. Removal of the key will prevent the drain of the battery by a short circuit, by a current draw, or by vandalism.


NOTICE

Never move the battery disconnect switch to the OFF position while the engine is operating. Serious damage to the electrical system could result.
