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
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.
WARNING
To avoid serious injury, perform maintenance
on the 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.
