easier handling. All models have

extra wide radial tires for superior traction.
Please carefully read this Manual which
tells you how to safely and easily unpack,
operate, and maintain your mower.
Be sure that you or any other user care-
fully follows the recommended safely
practices at all times. Failure to do so
could result in personal injury or property
damage.

WARNINGTO ALLCALIFORNIA
'_ ANDOTHERPOWEREQUIPMENTOPERATORS
Under California law, and under the laws of several other states,
you are not permitted to operate an internal combustion engine
using hydrocarbon fuels on any forest covered, brush cov-
ered, or grass covered land, or on land covered with grain,
hay, or other flammable agricultural crop, without an
engine spark arrester in continuous effective working order.
The engine on your power equipment, like most outdoor power equipment, is an
internal combustion engine that burns gasoline, a hydrocarbon fuel. Therefore,
your power equipment must be equipped with a spark arrester muffler in continu-
ous effective working order. The spark arrester must be attached to the engine
exhaust system in such a manner that flames or heat from the system will not
ignite flammable material. Failure of the owner/operator of the equipment to com-
ply with this regulation is a misdemeanor under California law, and may also be a
violation of other state and/or federal regulations, laws, ordinances, or codes.
Contact your local fire marshal or forest service for specific information about
what regulations apply in your area. Contact your authorized engine dealer for
information about obtaining a spark arrester.
