iTroubleshooting the Rider

AWARNING

To avoid serious injury, perform maintenance on the rider or mower only when the engine is stopped and the ground speed levers are set to PARK.

Always remove the ignition key, disconnect the spark plug wire and fasten it away from the plug before beginning the maintenance, to prevent accidental starting of the engine.
