Read this manual carefully to learn how to operate and maintain your product correctly. Reading this manual will help you and others avoid personal injury and damage to the product. Although Toro designs, produces, and markets safe, state-of-the-art products, you are responsible for using the product properly and safely. You are also responsible for training persons you allow to use the product about safe operation.

The Toro warning system in this manual identifies potential hazards and has special safety messages that help you and others avoid personal injury, even death. DANGER, WARNING, and CAUTION are signal words that identify the level of hazard. However, regardless of the hazard, be extremely careful. Two other words, "Important" and "Note," highlight information.

Signal Word Explanation

DANGER	Indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury.
WARNING	Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury.
CAUTION	Indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury. It may also be used to alert against unsafe practices that may cause property damage.
Important	Advises you of important information or instructions vital to the operation or maintenance of the equipment.

Note Advises you of additional information concerning the operation or maintenance of the equipment.

WARNING:

Read and understand all instructions. Failure to follow all instructions may result in serious personal injury as well as damage to the product.

This product has been designed and manufactured to meet or exceed the requirements of the current version of ANSI B175.3, safety requirements for gasoline-powered string trimmers and brushcutters.

■ Physical Condition of the Operator. Do not operate this product when tired, ill, or under the influence of alcohol, drugs, or medication.
■ Clothing Requirements. Always wear long heavy pants, boots, and gloves. Do not wear loose clothing, jewelry, short pants, sandals, or go barefoot. Secure hair so that it is above shoulder level to avoid entanglement in moving parts.
■ Protective Accessories Requirements. Wear eye protection marked to comply with ANSI Z87.1 standards when operating this product. Wear hearing protection during extended periods of operation.
■ Condition of Trimmer Before Use. Inspect the product before each use. Replace damaged parts. Check for fuel leaks. Make sure all fasteners are in place and secure. Replace cutting attachment parts that are cracked, chipped, or damaged in any way. Make sure the cutting attachment is properly installed and securely fastened. Be sure the cutting attachment shield is properly attached, and in the position recommended by the manufacturer. Use only flexible, non-metallic line recommended by the manufacturer. For example, never use wire or wire-rope, which can break off and become a dangerous projectile.
■ Proper Stance. Keep firm footing and balance. Do not overreach. Keep the cutting attachment below waist level. Keep all parts of your body away from the rotating cutting attachment and hot surfaces.
■ Exhaust Gases. Never start or run the product inside a closed room or building; breathing exhaust fumes can cause illness or death.
■ Fueling. Mix and pour fuel outdoors where there are no sparks and flames. Slowly remove the fuel cap only after stopping the engine. Do not smoke while fueling or mixing fuel. Wipe spilled fuel from the product. Move at least 30 ft. (9 m) away from the fueling source and site before starting the engine.
■ Work Area. Clear the area to be cut before each use. Remove all objects, such as rocks, broken glass, nails, wire, or string, that can be thrown or become

entangled in the cutting attachment. Clear the area of children, bystanders, and pets. At a minimum, keep all children, bystanders, and pets outside a 50 ft. (15 m) radius. Because there still may be a risk of injury to bystanders from thrown objects, bystanders should be encouraged to wear eye protection. If you are approached while operating the product, stop the engine and the cutting attachment.

■ Dangerous Environments. To avoid falling, do not use the product in damp or wet locations.

■ Controlling the Product. During carburetor adjustments the cutting attachment may spin. Therefore, you should wear protective equipment and observe all safety instructions when adjusting the carburetor. For products equipped with a clutch, be sure the cutting attachment stops turning when the engine idles. When the product is turned off, make sure the cutting attachment has stopped before setting down the product.

■ Use the Right Product. Use the product for the intended purpose only.

- Condition of Brushcutter Before Use. The handles shall be mounted according to the manufacturer's instructions. Do not attach any blade to a product without proper installation of all required parts. Failure to use the proper parts can cause the blade to fly off and seriously injure the operator and/or bystanders. Discard blades that are bent, warped, cracked, broken, or damaged in any way.

■ Use the Right Equipment. Always use the barrier bar on the front handle and the shoulder strap with the brushcutter.

■ Blade Thrust. Blade thrust may occur when the spinning blade contacts an object that it does not immediately cut. A blade thrust can be violent enough to cause the product and/or operator to be propelled in any direction, and possibly lose control of the product. Blade thrust can occur without warning if the blade snags, stalls, or binds. This is more likely to occur in areas where it is difficult to see the material being cut.

■ Stopping the Product. A coasting blade can cause injury while it continues to spin after the engine is stopped or throttle is released. Maintain proper control until the blade has completely stopped rotating.

Safety Rules

This engine is equipped with a spark arrester muffler. It is a violation of California Public Resource Code Section 4442 to use or operate this engine without a spark arrester muffler on any forest-covered, brush-covered, or grass-covered land. Other states or federal areas may have similar laws.

This spark ignition system complies with Canadian ICES-002.
