RULES FOR SAFE OPERATION
5
• 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 ft. (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.
WHILE OPERATING

room or building. Breathing exhaust fumes

ventilated area outdoors.

extended, and the proper line installed. Do
not extend the trimming line beyond the
length of the shield.

and rear handle or grips.
• Keep hands, face, and feet at a distance

parts get extremely hot from operation.
When turned off they remain hot for a
short time.
• Do not operate the engine faster than the
speed needed to cut, trim or edge. Do not
run the engine at high speed when not
cutting.
• Always stop the engine when cutting is

cutting attachment or other attachments.
• Use only genuine Ryobi replacement parts
when servicing this unit. These parts are

your warranty.
• Keep unit clean of vegetation and other
materials. They may become lodged
between the cutting attachment and shield.
