SAFETY RULES
Safe Operation Practices for Walk-Behind Powered Ro ta ry Tillers
TRAINING
• Read the Manual care ful ly. Be thor ough ly fa mil iar with
the controls and the proper use of the equip ment.
Know how to stop the unit and disengage the controls
quickly.
• Never allow children to operate the equipment. Never
allow adults to op er ate the equipment without proper
instruction.
• Keep the area of operation clear of all persons, par tic u lar ly small children, and pets.
PREPARATION
• Thoroughly inspect the area where the equipment is
to be used and remove all foreign objects.
• Disengage all clutches and shift into neutral before
starting the engine (mo tor).
• Do not operate the equipment with out wearing ad e quate outer gar ments. Wear footwear that will im prove
footing on slippery surfaces.
• Handle fuel with care; it is highly flammable.
• Use an approved fuel container.
• Never add fuel to a running engine or hot engine.
• Fill fuel tank outdoors with extreme care. Never fill fuel
tank indoors.
• Replace gasoline cap securely and clean up spilled
fuel before restarting.
• Use extension cords and receptacles as specified by
the manufacturer for all units with electric drive motors
or electric starting motors.
• Never attempt to make any adjustments while the
engine (motor) is running (except where specifically
rec om mend ed by manufacturer).
OPERATION
• Do not put hands or feet near or under rotating parts.
• Exercise extreme caution when op er at ing on or cross ing gravel drives, walks, or roads. Stay alert for hidden
hazards or traffic. Do not carry pas sen gers.
• After striking a foreign object, stop the engine (motor),
remove the wire from the spark plug, thoroughly in spect
the tiller for any damage, and repair the damage before
restarting and op er at ing the tiller.
• Exercise caution to avoid slipping or falling.
• If the unit should start to vibrate ab nor mal ly, stop the
engine (motor) and check immediately for the cause.
Vi bra tion is generally a warning of trouble.
• Stop the engine (motor) when leaving the operating
position.
• Take all possible precautions when leav ing the ma chine
unattended. Disengage the tines, shift into neutral, and
stop the engine.
• Before cleaning, repairing, or inspecting, shut off the
engine and make certain all moving parts have stopped.
Disconnect the spark plug wire, and keep the wire away
from the plug to prevent accidental starting. Disconnect
the cord on electric motors.
• Do not run the engine indoors; exhaust fumes are
dangerous.
• Never operate the tiller without proper guards, plates,
or other safety protective devices in place.
• Keep children and pets away.
• Do not overload the machine capacity by attempting
to till too deep at too fast a rate.
• Never operate the machine at high speeds on slippery
surfaces. Look behind and use care when backing.
• Never allow bystanders near the unit.
• Use only attachments and accessories approved by
the manufacturer of the tiller.
• Never operate the tiller without good visibility or light.
• Be careful when tilling in hard ground. The tines may
catch in the ground and propel the tiller forward. If this
occurs, let go of the handlebars and do not restrain the
machine.
MAINTENANCE AND STORAGE
• Keep machine, attachments, and accessories in safe
work ing condition.
• Check shear pins, engine mounting bolts, and other
bolts at frequent intervals for proper tightness to be
sure the equip ment is in safe working condition.
• Never store the machine with fuel in the fuel tank inside
a building where ignition sources are present, such
as hot water and space heaters, clothes dryers, and
the like. Allow the engine to cool before storing in any
enclosure.
• Always refer to the operator’s guide instructions for
im por tant details if the tiller is to be stored for an extended period.

• When you have completed your turn-around, release
the drive control bar and lower handle. Place shift lever in (till) position and move throttle control to de sired
speed. To begin tilling, hold drive control bar against
the handle.
CULTIVATING
• Use the forward rotating tine drive when cultivating,
tilling soft ground or tilling pre-tilled soil.
• Release depth and drag stake pins. Lower drag stake.
Pull the depth stake up for increased tilling depth. Place
proper pin in hole of depth stake or drag stake to lock
in position.
• Place shift lever indicator in ( )till position.
• Hold the drive control bar against the handle to start
tilling movement. Tines and wheels will both turn.
• Move throttle control "FAST" position for deep tilling.
To cultivate, throttle control can be set at any desired
speed, depending on how fast or slow you wish to
cultivate.
• Always lower the drag stake when using the for ward
rotating tine drive.
TO TRANSPORT
CAUTION: Before lifting or trans port ing,
allow tiller engine and muffler to cool.
Disconnect spark plug wire. Drain
gasoline from fuel tank.
AROUND THE YARD
• Release the depth stake pin. Move the depth stake
down to the top hole for transporting the tiller. Place
depth stake pin in hole of depth stake to lock in position. This prevents tines from scuffing the ground.
• Place shift lever indicator in “F” (forward) position for
transporting.
• Hold the drive control bar against the handle to start
tiller movement. Tines will not turn.
• Move throttle control to desired speed.
AROUND TOWN
• Disconnect spark plug wire.
• Drain fuel tank.
• Transport in upright position to prevent oil leakage.
BEFORE START ING ENGINE
IMPORTANT: BE VERY CAREFUL NOT TO ALLOW DIRT
TO ENTER THE ENGINE WHEN CHECKING OR ADDING
OIL OR FUEL. USE CLEAN OIL AND FUEL AND STORE IN
APPROVED, CLEAN, COVERED CONTAINERS. USE CLEAN
FILL FUNNELS.
CHECK ENGINE OIL LEVEL (See Fig. 13)
• The engine in your unit has been shipped, from the
factory, already filled with SAE 30 summer weight oil.
• With engine level, clean area around oil filler plug and
remove plug.
• Engine oil should be to point of overflowing when engine
is level. For ap proxi mate capacity see “PROD UCT
SPEC I FI CA TIONS” on page 3 of this manual. All oil
must meet A.P.I. Service Classification SG-SL.
• Reinstall engine oil cap and tighten.
• For cold weather operation you should change oil for
easier starting (See oil viscosity chart in the Maintenance sec tion of this manual).
• To change engine oil, see the Maintenance section in
this manual.
OUTER SIDE SHIELDS (See Fig. 12)
The back edges of the outer side shields are slotted so
that the shields can be raised for deep tilling and low ered
for shal low tilling to protect small plants from being buried.
Loosen nut “A” in slot and nut “B”. Move shield to desired
position (both sides). Retighten nuts.
