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 caus-
es and remedies.
If you prefer, all of these procedures can be performed
for you by a dealer. Locate and contact a dealer through
www.simplicitymfg.com.
WARNING
To avoid serious injury, perform maintenance on
the rider or mower only when the engine is
stopped and the parking brake set to PARK.
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.
