thrown or become entangled in the attachment. 

• Use only 0.080 inch (2.03 mm) diameter genuine OEM

replacement line. Never use metal-reinforced line, wire,

dangerous projectile. 

• This unit was not designed to be used as a 

brushcutter. Do not attach or operate this unit with any
type of brushcutting blade or brushcutting attachment.

WARNING: Gasoline is highly flammable, and its vapors can

explode if ignited. Take the following precautions:

• Store fuel only in containers specifically designed and

approved for the storage of such materials.

• Always stop the engine and allow it to cool before filling the

fuel tank. Never remove the cap of the fuel tank, or add fuel,
when the engine is hot. Never operate the unit without the
fuel cap securely in place. Loosen the fuel tank cap slowly
to relieve any pressure in the tank.

• Mix and add fuel in a clean, well-ventilated area outdoors

where there are no sparks or flames. Slowly remove the fuel
cap only after stopping engine. Do not smoke while fueling
or mixing fuel. Wipe up any spilled fuel from the unit
immediately. 

• Avoid creating a source of ignition for spilled fuel. Do not

start the engine until fuel vapors dissipate.

• Move the unit at least 30 feet (9.1 m) from the fueling source

and site before starting the engine. Do not smoke. Keep
sparks and open flames away from the area while adding
fuel or operating the unit.

• Never start or run the unit inside a closed room or building.

Breathing exhaust fumes can kill. Operate this unit only in a
well ventilated area outdoors. 

WARNING: To reduce the risk of electrical
shock, use only extension cords approved for
outdoor use, such as an extension cord of cord
type SW-A, SOW-A, STW-A, STOW-A, SJW-A,
SJOW-A, SJTW-W or SJTOW-A. Extension
cords are available from your local retailer. Use
only round-jacketed extension cords approved
for outdoor use.

• CORD SETS: Make sure your cord set is in good

condition. When using a cord set, be sure to use a
cord that is heavy enough to carry the current that your
unit will draw. An undersized cord set will cause a drop
in line voltage resulting in loss of power and
overheating. See the operator’s manual for the unit that
will power this add-on for the recommended cord size.

• Inspect all extension cords and the unit power

connection periodically. Look closely for deterioration,
cuts or cracks in the insulation. Also inspect the
connections for damage. Replace the cords if any
defects or damage appear.

• Prevent disconnection of the straight shaft trimmer

powerhead from extension cord during operation by
using a plug-receptacle retaining strap, connector, or
by making a knot as shown below:

• Avoid dangerous environments. Never operate your unit in

damp or wet conditions. Moisture is a shock hazard.
