Troubleshooting, Adjustments, & Service
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.
See the information on the following pages for instruc- tions on how to perform most of these minor adjustments and service repairs yourself. If you prefer, all of these procedures can be performed for you by your local authorized dealer.
WARNING
To avoid serious injury, perform maintenance on the tractor or mower only when the engine is stopped and the parking brake engaged.
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.
