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.
