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.
A 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.
