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 operat-
ing properly.
The troubleshooting guide below lists the most common prob-
lems, their causes and remedies.
See the information on the following pages for instructions 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.

To avoid serious injury, perform maintenance on the rider 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.
