The purpose of safety symbols is to attract your 
attention to possible dangers. The safety symbols, 
and their explanations, deserve your careful attention
and understanding. The safety warnings do not by 
themselves eliminate any danger. The instructions or
warnings they give are not substitutes for proper 
accident prevention measures.

• IMPORTANT SAFETY INSTRUCTIONS •

• 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 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. 

SAFETY WARNINGS FOR ELECTRIC TRIMMERS 

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.

• Avoid dangerous environments. Never operate your

unit in damp or wet conditions. Moisture is a shock
hazard.

• Do not use the unit in the rain.

• Do not handle the plug or unit with wet hands or

standing on any wet surfaces.

• Do not leave the unit plugged in when not in use,

changing attachments or add-ons, or while 
being serviced.

READ ALL INSTRUCTIONS 

BEFORE OPERATING

• Read the instructions carefully. Be familiar with the

controls and proper use of the unit. Carefully read this
manual and the operator’s manual of the unit that will
power this add-on.

• Do not operate this unit when tired, ill, or under the

influence of alcohol, drugs, or medication.

• Children and teens under the age of 15 must not use

the unit, except for teens guided by an adult.

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

replacement line. Never use metal-reinforced line,
wire, or rope, etc.. These can break off and become a
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.

SAFETY WARNINGS FOR GAS TRIMMERS

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.
