use of the equipment. Know how to stop the unit and disengage the controls quickly.
2. THOROUGHLY INSPECT the area to be tilled or cultivated and remove all foreign objects.
3. DO NOT operate the machine without wearing adequate outer garments. Wear footwear which will improve footing
on slippery surfaces and will resist penetration.
4. HANDLE FUEL WITH CARE, IT IS HIGHLY FLAMMABLE.
a) Use an approved fuel container.
b) NEVER add fuel to a running engine or to a hot engine.
c) Fill fuel tank outdoors with extreme care. Never fill fuel tank indoors.
d) Replace gasoline cap securely and clean up spilled fuel before restarting.
5. Before starting engine, be sure that the throttle lever is released so that the centrifugal clutch is not engaged.
6. NEVER attempt to make any adjustments while the engine is running (except when recommended).
OPERATION
1. NEVER transport this machine when the engine is running. SHUT THE ENGINE OFF before transporting the
machine.
2. DO NOT put hands or feet near or under rotating parts.
3. SHUT OFF ENGINE before crossing gravel drives, walks, or roads. Stay alert for hidden hazards or traffic.
4. After striking a foreign object, STOP THE ENGINE. Disconnect the spark plug wire, and keep the wire away from the
plug to prevent accidental starting. Thoroughly inspect the machine for any damage and repair the damage before
restarting and operating.
5. EXERCISE CAUTION to avoid slipping or falling.
6. If the machine should start to vibrate abnormally, STOP THE ENGINE, disconnect the spark plug wire, and check
immediately for the cause. Vibration is generally a warning of trouble.

17. DO NOT till or cultivate near underground electrical cables, telephone lines, pipes, or hoses. If in doubt about their
location, contact your telephone or utility company to locate underground services.

WARNING: TO PURCHASERS OF INTERNAL COMBUSTION ENGINE EQUIPPED
MACHINERY OR DEVICES
This equipment does not include a spark arresting muffler.
Under California Law, you are not permitted to operate an internal combustion engine using hydrocarbon fuels on
any forest covered, brush covered, or grass covered land, or land covered with grain, hay, or other flammable agricultural crop, without an engine spark arrestor in continuous effective working order. The engine on your Tiller/Cultivator, like most garden equipment, is an internal combustion engine that burns gasoline, a hydrocarbon fuel; therefore, it must be equipped with a spark arrestor muffler in proper working order. The spark arrestor 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 operator to comply with this regulation is a misdemeanor under California Law.
WARNING: THE ENGINE EXHAUST FROM THIS PRODUCT CONTAINS
CHEMICALS KNOWN TO THE STATE OF CALIFORNIA TO CAUSE CANCER,
BIRTH DEFECTS OR OTHER REPRODUCTIVE HARM.
