This unit is equipped with an internal combuition engine and should not be used on or near any unimproved forest-covered, brush-covered or grass-coverec land unless the engine's exhaust system is equipped with a spark arrester meeting applicable local or state jaws (ifany). If a spark arrester is used, it should be maintained
in effective working order by the operator.
In the State of California the above is required by law (Section 4442 of the California Public Resources Code). Other states may have similar laws. Federal lav/s apply on federal lands. A spark arrester muffler is available at

reduce the potential for any injury, comply with the following safety instructions. Failure to comply with the
istructions may result in personal injury.
SAFE OPERATION PRACTICES FOR EDGERS

TRAINING

1. Read this owner's manual carefully in its en
tirety before attempting to assemble or operate this machine. Be completely familiar with the controls and the proper use of this machine be fore operating it. Keep this manual in a safe place for future and regular reference and for ordering
replacement parts.
2. Your edger is a precision piece of power equip
ment, not a plaything. Therefore, exercise extreme
caution at all times.
3. Never allow children to operate a power edger. Only persons well acquainted with these rules of safe operation should be allowed to use your edger.
4. Keep the area of operation clear of all persons,
particularly small children and pets. Stop engine when they are in the vicinity of your edger. Al
though the area of operation should be complete
ly cleared of foreign objects, an object may have
been overlooked and could be accidently thrown by the edger in any direction and cause serious
... personal injury to the operator or any others
allowed in the area.
d. No one should operate this unit while intoxicated
or while taking medication that impairs the senses or reactions.

PREPARATION

1. Thoroughly inspect the area where the equip ment is to be used. Remove all stones, sticks,
wire, bones and other foreign objects which could be picked up and thrown by the edger in any direction and cause serious personal injury to
the operator or any others allowed in the area.
2. Do not operate equipment when barefoot or wear ing open sandals. Always wear substantial foot
wear.
3. Check the fuel before starting the engine. Gasoline is an extremely flammable fuel. Do not fill the
gasoline tank indoors, while the engine is running, or while the engine is still hot. Wipe off any spilled gasoline before starting the engine as it
may cause a fire or explosion.
4. Disengage the blade clutch on units so equipped
before starting the engine. Never attempt to make a wheel adjustment while
the engine is running.
6. Never operate the equipment in wet grass. Always be sure of your footing. A slip and fall can cause serious personal injury. Keep a firm hold on the handle and walk, never run.

OPERATION

1. Never operate this edger unless wearing safety glasses or some other suitable eye protection at all times the engine is running.
2. Do not change the engine governor settings or
overspeed the engine.
3. Do not put hands or feet near or under rotating parts. Keep clear of the discharge opening at all times as the rotating blade can cause injury.
4. Stop the blade when crossing gravel drives, walks
or roads.
5. After striking a foreign object, stop the engine,
remove the wire from the spark plug, and thor
oughly inspect the edger for any damage. Repair the damage before restarting and operating the edger.
6. If the equipment should start to vibrate abnor
mally, stop the engine and check immediately for the cause. Vibration is generally a warning of trouble.
7. Stop the engine whenever you leave the equip
ment, before cleaning the guard assembly, and when making any repairs or inspections.
8. Before cleaning, repairing or inspecting, make
certain the blade and all moving parts have stop ped. Disconnect the spark plug wire, and keep
the wire away from the spark plug to prevent accidental starting.
9. Do not run the engine indoors.
10. Shut the engine off and wait until the blade comes to a complete stop before unclogging guard assembly.
11. Never operate edger without proper guards, plates or other safety protective devices in place.
12. Always operate the edger so that the protective guard guide is positioned between the walk and the rotating blade. Never allow the rotating blade to operate directly against concrete walk or drive.

MAINTENANCE AND STORAGE

1. Check the blade and engine mounting bolts at
frequent intervals for proper tightness.
2. Keep all nuts, bolts, and screws tight to be sure the equipment is in safe working condition.
3. Never store the equipment with gasoline in the tank inside of a building where fumes may reach
an open flame or spark. Allow the engine to cool before storing in any enclosure.
4. To reduce fire hazard, keep the engine free of
grass, leaves, or excessive grease.
