Accidental engine starting can cause injury or death to personnel working on the equipment. To avoid accidental engine starting, disconnect the battery cable from the negative (−) battery terminal. Completely tape all metal surfaces of the disconnected battery cable end in order to prevent contact with other metal surfaces which could activate the engine electrical system. Place a Do Not Operate tag at the Start/Stop switch location to inform personnel that the equipment is being worked on.

1. The engine can start automatically. Ensure that the power supply is isolated before any service or repairs is performed.

2. Turn the battery disconnect switch to the OFF position.

3. Place identification marks on the harness assembly that is connected to the electric starting motor and the solenoid.
