Craftsman ZT 7000 107.2777 Operator's Manual page 31

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 problems, their causes and remedies.
If you prefer, all of these procedures can be performed for you
by a Sears Parts & Repair Center. See the back cover for
important Sears Parts & Repair Center information.
,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.
