SAFE PRACTICES FOR GARDEN TILLERS
TRAINING
Regard your tiller as a piece of power equipment and teach
this respect to all who operate it.
Read the owner’s manual carefully. Be thoroughly familiar
with the controls and proper use of the equipment. Know
how to stop the unit and disengage the controls quickly.
Never allow children to operate equipment. Never allow
adults to operate equipment without proper instruction.
Keep the area of operation clear of all persons, especially
small children.
Exercise caution to avoid slipping and falling.
PREPARATION
Check the tiller to make certain it is in good operating condition.
Check tines to be sure they are free of any obstruction.
Check engine crankcase oil level.
Unless there is very good articial light operate during day-
light hours only.
Do not operate power tools in wet soil, which clogs the
cutter and increases the danger of your slipping and falling
and possibly coming into contact with the tines.
Thoroughly inspect the area where the equipment is to be
used and remove all large stones, boards, wires, and other
foreign objects.
Do not operate machine when barefoot or wearing open
sandals. Wear strong work-type footwear which will
improve footing and provide optimum protection. Provide
leg protection by means of long, heavy denim trousers and
brogues.
Check that clutch is disengaged before starting engine.
Handle fuel with care; it is highly ammable.
• Use approved fuel container.
• Never add fuel to a running engine or hot engine.
• Fill fuel tank outdoors with extreme care. Never ll fuel
tank while smoking.
• Replace gasoline cap securely and wipe up spilled fuel.
Never attempt to make any adjustments while engine is
running except carburetor mixture as instructed in the engine owner’s guide.
Allow engine sufcient warm-up period before tilling.
OPERATION
Give complete and undivided attention to the job at hand.
Familiarize yourself with the controls. Be sure you know
how to stop your machine quickly. Do not start engine until
you set machine on ground to be tilled.
Hold the handle with your left hand while pulling the starter
rope with your right. Be sure the machine will not tip or roll
during the starting operation.
Stay clear of the front of self-propelled machine during
and after starting. Do not put hands or feet near rotating
tines or belt when machine is operating. Once machine is
started stand behind it with hands on handles at all times.
Keep in step with machine. Do not lag behind or let it pull
you so you will not be in full command of the machine.
Control the direction of the machine by hand pressure on
the handle, not by foot pressure on the machine housing.
Stay alert for hidden hazards.
When operating over uneven terrain and slopes, use
extreme care and make sure of solid and rm footing at all
times.
Exercise special care when operating around objects to
prevent the tines from striking them and never deliberately
operate over any object.
After striking a foreign object, stop the engine, remove wire
from spark plug, thoroughly inspect the tiller for any damage and repair the damage before restarting and operating
the tiller.
If the unit should start to vibrate abnormally, stop the
engine and check immediately for the cause. Vibration is
generally a warning of trouble.
Stop operation when another person approaches.
Stop the engine whenever you leave the operating position
before making any repairs, adjustment, or inspections.
Stop the engine whenever leaving the tiller unattended.
When cleaning, repairing, or inspecting make certain tines
and all moving parts have stopped. Disconnect spark plug
wire and keep wire away from plug to prevent accidental
starting.
Do not run engine indoors.
Exercise extreme caution when changing direction on
slopes. Do not attempt to till steep slopes.
Never operate tiller without guards, plates, or other safety
protective devices in place.
Never operate tiller near glass enclosure, automobiles,
window wells, drop-offs, or bystanders. Keep children and
pets away.
Do not over load machine capacity by attempting to till
ground at too fast a rate.
Use care when backing.
Never allow anyone in front of unit. Disengage clutch,
when someone approaches, when transporting or when not
in use.
Use only attachments and accessories approved by manufacturer of tiller.
Never operate tiller without good visibility or light. Always
be sure of your footing and keep a rm hold on the handles
and walk, never run.

intervals for proper tightness to be sure equipment is in
safe working condition. Check that the engine stop circuit
is intact.
Never adjust the machine or change attachments until the
engine has been turned off and the spark plug wire discon-

materials may result in a re.
Store gasoline in a safe container. Store the container in
a cool, dry place, not in the house or near heating appliances.
Never store machine with fuel in the fuel tank inside a building where open ame or sparks are present. Allow engine
to cool before storing in any enclosure.
