RULES FOR SAFE OPERATION

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

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.

Wear safety glasses or goggles that are marked as meeting ANSI Z87.1-1989 standards, and ear/hearing protection when operating this unit. Wear a face or dust mask if the operation is dusty. Long sleeve shirts are recommended.

Wear heavy, long pants, boots and gloves. Do not wear loose clothing, jewelry, short pants, sandals or go barefoot. Secure hair above shoulder level.

The cutting attachment shield must always be in place while operating the unit. Do not operate unit without both trimming lines extended, and the proper line installed. Do not extend the trimming line beyond the length of the shield.

This unit does not have a clutch. The cutting attachment rotates when the engine is idling.

Adjust the D-handle to your size to provide the best grip.

Be sure the cutting attachment is not in contact with anything before starting the unit.

Use the unit only in daylight or good artificial light.

Avoid accidental starting. Be in the starting position whenever pulling the starter rope. The operator and unit must be in a stable position while starting. See Starting/Stopping Instructions.

Use the right tool. Only use this tool for the purpose intended.

Do not overreach. Always keep proper footing and balance.

Always hold the unit with both hands when operating. Keep a firm grip on both the front and rear handle or grips.

Keep hands, face, and feet at a distance from all moving parts. Do not touch or try to stop the cutting attachment when it is rotating.

Do not touch the engine or muffler. These 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 delayed or when walking from one cutting location to another.

If you strike or become entangled with a foreign object, stop the engine immediately and check for damage. Do not operate before repairing damage. Do not operate the unit with loose or damaged parts.

Stop and switch the engine to off for maintenance, repair, or for changing the cutting attachment or other attachments.

Use only genuine Ryobi replacement parts when servicing this unit. These parts are available from your authorized service dealer. Do not use parts, accessories or attachments not authorized by Ryobi for this unit. Doing so could lead to serious injury to the user, or damage to the unit, and void your warranty.

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

To reduce fire hazard, replace faulty muffler and spark arrestor, keep the engine and muffler free from grass, leaves, excessive grease or carbon build up.
