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.
• Inspect the throttle control lever and cable. Make sure
that the cable is free and that the lever is not damaged.
Also check the cable linkage running to the carburetor for
kinks, loose fittings, and obstructions. Verify that the start
lever is working properly.

good condition. Check mounting hardware on trimmer
head every time you change trimmer line prior to each use.

SPECIFIC SAFETY RULES
FUEL SAFETY
• Handle fuel with care; it is highly flammable.

expansion as the heat of the engine and/or sun can cause
fuel to expand.
• Fill fuel tank outdoors with extreme care. Never fill fuel
tank indoors.
• Never remove gas cap or add fuel with the engine running.
Allow engine to cool before refueling.
• Do not smoke while refueling.
• After refueling, replace fuel tank cap securely and wipe up
spilled fuel.
• Never store fuel or trimmer with fuel in the tank inside a
building where fumes may reach an open flame.
STORAGE SAFETY
• Always refer to the operator’s manual instructions for
important details if the trimmer is to be stored for an
extended period.

building where ignition sources are present such as water
heaters, space heaters, clothes dryers, etc.

or other debris build-up.
• Allow the engine to cool before storing in any enclosure.
REPAIR, MAINTAINANCE, AND ADJUSTMENT
SAFETY
• 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 trimmer 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.

is running except when specifically recommended by the
manufacturer
• Keep the trimmer in safe working condition. Check all
fasteners at frequent intervals for proper tightness.
• When servicing or repairing the trimmer, do not tip the
machine over or up unless specifically instructed to do so
in this Manual. Service and repair procedures can be
done with the trimmer in an upright position. Some
procedures will be easier if the machine is lifted on a
raised platform or working surface.

parts.
• Never tamper with safety devices. Check their proper
operation regularly.
• Do not change the engine governor setting or over-speed
engine.
• Clean and replace safety and instruction decals as
necessary.

presence of children. Children are often attracted to the
trimmer and the trimming activity.
• Keep children out of the trimming area and under the
watchful care of a responsible adult.

them.
• Be alert and turn trimmer off if children enter the area.
