ignition switch, controller, or any other electrical
components, or at bearing housings and seals.

soap solution and warm water, or use commercially
available vinyl/rubber cleaners.
Repair damaged metal surfaces and use Jacobsen
touch-up paint. Wax the equipment for maximum paint
protection.
WARNING
Make sure the mower is parked on a solid and level
surface. Never work on a mower that is supported only
by the jack. Always use jack stands.
If only the front or rear of the mower is raised, place
chocks in front of and behind the wheels that are not
raised.

NOTICE
Do not wash any portion of the equipment while it is hot.
Do not use high pressure spray or steam. Use cold water
and automotive cleaners.
NOTICE
Use of salt water or affluent water has been known to
encourage rust and corrosion of metal parts resulting
in premature deterioration or failure. Damage of this
nature is not covered by the factory warranty.
CAUTION
Clean grass and debris from cutting units, drives,
muffler, and engine to prevent fires.
WARNING
NEVER use your hands to clean cutting units. Use a
brush to remove grass clippings from blades. Blades
are extremely sharp and can cause serious injuries.
