SAFETY RULES
Safe Operation Practices for Cultivator
WARNING: Look for this symbol to point out important safety precautions.
It means: “Attention! Become Alert! Your Safety Is Involved.”
WARNING: To prevent accidental starting when setting−up,
transporting, adjusting or making repairs, always disconnect spark
plug wire and put wire where it cannot
contact the spark plug .
IMPORTANT: Safety standards require opera-
tor presence controls to minimize the risk of injury. Your cultivator is equipped with such
controls. Do not attempt to defeat the function
of the operator presence control under any circumstances.
Before Use
S Read the owner’s manual carefully. Be
thoroughly familiar with the controls and
the proper use of the cultivator. Know how
to stop the cultivator and disengage the
controls quickly.
S Do not operate the cultivator without wear-
ing adequate outer garments. Wear footwear that will improve footing on slippery
surfaces.
S Keep the area of operation clear of all per-
sons, particularly small children and pets.
S Thoroughly inspect the area where the cul-
tivator is to be used and remove all foreign
objects.
S Keep in mind that the operator or user is
responsible for accidents or hazards occurring to other people, their property, and
themselves.
S Disengage all clutches and shift into neu-
tral before starting the engine (motor).
Fuel Safety
S Handle fuel with care; it is highly flam-
mable.
S Use an approved container.
S Check fuel supply before each use, allow-
ing space for expansion as the heat of the
engine and/or sun can cause fuel to expand.
MS−3615MA
S Fill fuel tank outdoors with extreme care.
Do not smoke while refueling. Never fill fuel
tank indoors. Replace fuel tank cap securely and wipe up spilled fuel.
S If fuel is spilled, do not attempt to start the
engine but move the machine away from
the area of spillage and avoid creating any
source of ignition until fuel vapors have dissipated.
S Never remove the fuel tank cap or add fuel
to a running or hot engine.
S Never store fuel or cultivator with fuel in the
tank inside a building where fumes may
reach an open flame.
Operating Safety
S Never allow children or young teenagers to
operate the cultivator. Keep them away
while it is operating. Never allow adults to
operate the cultivator without proper instruction.
S Do not operate this machine if you are tak-
ing drugs or other medication which can
cause drowsiness or affect your ability to
operate this machine.
S Do not use this machine if you are mentally
or physically unable to operate this machine safely.
S Always wear safety glasses or eye shields
during operation or while performing an
adjustment or repair to protect your eyes
from foreign objects that may be thrown
from the cultivator.
S Do not put hands or feet near or under ro-
tating parts.
S Exercise extreme caution when operating
on or crossing gravel drives, walks, or
roads. Stay alert for hidden hazards or
traffic.

SAFETY RULES
proved by the manufacturer of the machine
(such as wheel weights, counterweights,
and the like.
S Never operate the cultivator at high trans-
port speeds on hard or slippery surfaces.
Look behind and use care when backing.
S Never allow bystanders near the cultivator.
S Keep children and pets away while
operating.
S Never operate the cultivator without good
visibility or light.
S 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.
S Use extreme care when reversing or pull-
ing the machine towards you.
S Do not change the engine governor set-
tings or overspeed the engine.
S Start the engine or switch on the motor
carefully according to instructions and with
feet well away from the tines.
S Never pick up or carry a machine while the
engine is running.
S Do not run the engine indoors. The ex-
haust fumes are dangerous, containing
CARBON MONOXIDE, an ODORLESS
and DEADLY GAS.
S Take all possible precautions when leaving
the cultivator unattended. Stop the engine,
and if equipped, remove the key.
S Do not overload the cultivator capacity by
attempting to till too deep at too fast a rate.
Safe Storage
S Always refer to the owner’s manual instruc-
tions for important details if the cultivator is
to be stored for an extended period.
S Never store the cultivator with fuel in the
fuel tank inside a building where ignition
sources are present such as water and
space heaters, clothes dryers, and the like.
Allow the engine to cool before storing in
any enclosure.
S If the fuel tank has to be drained, do this
outdoors.
S Keep the cultivator in safe working condi-
tion. Check all fasteners at frequent intervals for proper tightness.
Repair / Adjustments Safety
S After striking a foreign object, stop the en-
gine. Remove the wire from the spark plug,
and keep the wire away from the plug to
prevent accidental starting. Thoroughly inspect the cultivator for any damage, and
repair the damage before restarting and
operating it.
S If cultivator should start to vibrate abnor-
mally, stop engine and check immediately
for the cause. Vibration is generally a warning of trouble.
S Stop the engine whenever you leave the
operating position. Also, disconnect the
spark plug wire before unclogging the tines
and when making any repairs, adjustments, or inspections.
S When cleaning, repairing, or inspecting,
shut off the engine and make certain all
moving parts have stopped.
S Never attempt to make any adjustments
while the engine is running except when
specifically recommended by the manufacturer.
