TROUBLESHOOTING

While normal care and regular maintenance will extend the life of your equipment, prolonged or constant use may eventually require that service be performed to allow it to continue operating properly. The troubleshooting guide below lists the most common problems, their causes and remedies.

If you prefer, all of these procedures can be performed by your local authorized dealer.

WARNING

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

ENGAGE.

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.
