• Familiarize yourself with all the safety and operating decals on this
equipment.

• Thoroughly inspect the area where the edger is to be used and remove
all foreign objects. Your equipment can propel small objects at high
speed causing personal injury or property damage. Stay away from
breakable objects, such as house windows, auto glass, greenhouses,
etc.
• Check that all nuts and bolts are tight and equipment is in good
condition.

• Always check that the ameout wire is connected before starting
engine.

• Never allow children or young teenagers to operate the edger.

• Keep area of operation clear of all bystanders, particularly small
children and pets.
• Only allow responsible individuals, who are familiar with the
instructions, to operate the edger.

• Do not operate the edger while under the inuence of alcohol, drugs,
or other medication which can cause drowsiness or affect your ability
to operate this machine safely.
• Do not use this machine if you are mentally or physically unable to
operate the machine safely.
• Always wear ANSI compliant safety goggles or safety glasses with side
shields when operating edger to protect your eyes from foreign objects,
which can be thrown from the unit.
• Wear appropriate clothing such as a long sleeved shirt or jacket. Also
wear long trousers or slacks. Do NOT wear shorts. Do NOT wear loose
clothing, which could get caught in this equipment.
• Always wear work gloves and sturdy footwear such as leather work
shoes or short boots. These will protect ankles and shins from small
sticks, splinters, and other ying debris, and improve traction.
• It is advisable to wear protective headgear to protect against being
struck by small ying particles, or being struck by low hanging
branches, twigs, or other objects, which may be unnoticed by the

7
operator.

• Do not put hands or feet near or under rotating parts.
• Exercise extreme caution when operating on or crossing gravel drives,
walks, or roads. Stay alert for hidden hazards or trafc.

• Exercise caution to avoid slipping or falling. Always be sure of your
footing; keep a rm hold on the handle and walk; never run. Never
operate the edger at high transport speeds on slippery surfaces.
• Look behind and use care when backing.
• Never operate the edger without good visibility or light.

• Do not run the engine indoors or inside a closed area. The exhaust
fumes are dangerous, containing CARBON MONOXIDE, an
ODORLESS AND DEADLY GAS.
• Never leave the edger unattended when the engine is running. Stop
the engine and make sure all moving parts have stopped. Remove the
wire from the spark plug.
• Do not overload the edger capacity by attempting to till too deep at too
fast a rate.
• If the edger should start to vibrate abnormally, stop the engine,
disconnect the spark plug wire and prevent it from touching the spark
plug. Check immediately for the cause. Vibration is generally a warning
of trouble.
• Watch for holes, ruts, bumps, or other rough ground. Tall grass can
hide obstacles.

• Gasoline is extremely ammable, and gasoline vapors can explode if
ignited. Handle with care.
• Use an approved container.
• Check fuel supply before each use, allowing space for expansion as
the heat of the engine and/or sun can cause fuel to expand.
• Fill fuel tank outdoors with extreme care. Never ll fuel tank indoors.
• Never remove gas cap or add fuel with the engine running. Allow
engine to cool before refueling.


• After striking a foreign object, stop the engine. Remove the wire
from the spark plug and keep the wire away from the plug to prevent
accidental starting. Thoroughly inspect the edger for any damage. If
damaged, have the equipment repaired by a trained technician before
restarting and operating.
• Stop the engine before cleaning, repairing, or inspecting the unit. Make
sure all moving parts have stopped. Let the engine cool, disconnect
the spark plug wire and move it away from the spark plug.
• Never attempt to make any adjustments while the engine is running
except when specically recommended by the manufacturer.
• Keep the edger in safe working condition. Check all fasteners at
frequent intervals for proper tightness.
• When servicing or repairing the edger, do not tip the machine over or
up unless specically instructed to do so in this Manual. Service and
repair procedures can be done with the edger in an upright position.
Some procedures will be easier if the machine is lifted on a raised
platform or working surface.
• Use only original equipment or authorized replacement parts.

• Never tamper with safety devices. Check their proper operation
regularly.
