General Safety Rules

WARNING:

Read and understand all instructions. Failure to follow all instructions may result in electric shock, fire and/or serious personal injury.

read all instructions

For safe operation, read and understand all instructions before using this product. Follow all safety instructions. Failure to follow all safety instructions listed below, can result in serious personal injury.

Do not allow children or untrained individuals to use this unit.

Do not start or operate the engine in a confined space, building, near open windows, or in other unventilated space where dangerous carbon monoxide fumes can collect. Carbon monoxide, a colorless, odorless, and extremely dangerous gas, can cause unconsciousness or death.

Clear the work area before each use. Remove all objects such as rocks, broken glass, nails, wire, or loose string which can be thrown or become entangled in the cutting line or blade.

Always wear eye protection with side shields marked to comply with ANSI Z87.1 along with hearing protection when operating this equipment.

Wear heavy, long pants, long sleeves, boots, and gloves. Do not wear loose fitting clothing, short pants, sandals, or go barefoot. Do not wear jewelry of any kind.

Heavy protective clothing may increase operator fatigue, which could lead to heat stroke. During weather that is hot and humid, heavy work should be scheduled for early morning or late afternoon hours when temperatures are cooler.

Product users on United States Forest Service land, and in some states, must comply with fire prevention

regulations. This product is equipped with a spark arrestor; however, other user requirements may apply. Check with your federal, state, or local authorities.

Never operate this unit on the operator’s left side.

Secure long hair above shoulder level to prevent entanglement in moving parts.

Keep all bystanders, children, and pets at least

50 ft. (15 m) away. Bystanders should be encouraged to wear eye protection. If you are approached, stop the engine and cutting attachment. If you are using a brush cutter attachment, there is the added risk of injury to bystanders from being struck with the moving blade in the event of a blade thrust or other unexpected reaction of the saw.

Do not operate this unit when you are tired, ill, upset, or under the influence of alcohol, drugs, or medication.

Do not operate in poor lighting.

Keep firm footing and balance. Do not overreach. Overreaching can result in loss of balance or exposure to hot surfaces.

Keep all parts of your body away from any moving part.

To avoid hot surfaces, never operate the unit with the bottom of the engine above waist level.

Do not touch area around the muffler or cylinder of the unit, these parts get hot from operation. Contact with hot surfaces could result in possible serious personal injury.

Always stop the engine and remove the spark plug wire before making any adjustments or repairs except for carburetor adjustments.

Inspect the unit before each use for loose fasteners, fuel leaks, etc. Replace any damaged parts before use.

The cutting attachment should never rotate at idle during normal use. The cutting attachment may rotate at idle during carburetor adjustments.

It has been reported that vibrations from hand-held tools may contribute to a condition called Raynaud’s

Syndrome in certain individuals. Symptoms may include tingling, numbness, and blanching of the fingers, usually apparent upon exposure to cold. Hereditary factors, exposure to cold and dampness, diet, smoking, and work practices are all thought to contribute to the development of these symptoms. It is presently unknown what, if any, vibrations or extent of exposure may contribute to the condition. There are measures that can be taken by the operator to possibly reduce the effects of vibration:

a)Keep your body warm in cold weather. When operating the unit wear gloves to keep hands and wrists warm. It is reported that cold weather is a major factor contributing to Raynaud’s Syndrome.

b)After each period of operation, exercise to increase blood circulation.

c)Take frequent work breaks. Limit the amount of exposure per day.

d)Keep the tool well maintained, fasteners tightened, and worn parts replaced.

If you experience any of the symptoms of this condition, immediately discontinue use and see your physician about these symptoms.

Mix and store fuel in a container approved for gasoline.

Mix fuel outdoors where there are no sparks or flames.

Wipe up any fuel spillage. Move 30 ft. (9 m) away from refueling site before starting engine. Slowly remove the fuel cap after stopping engine. Do not smoke when refueling.

Stop the engine and allow to cool before refueling or storing the unit.

Safety Rules

Allow the engine to cool; empty the fuel tank into a container approved for fuel and secure the unit from moving before transporting in a vehicle.

Wear your protective equipment and observe all safety instructions. For units equipped with a clutch, be sure the cutting attachment stops turning when the engine idles. When the unit is turned off make sure the cutting attachment has stopped before the unit is set down.

Specific Safety Rules

Specific Safety Rules For Trimmer Use

Make sure all guards, straps, deflectors, and handles are properly and securely attached.

Never use blades, flailing devices, wire, or rope. Use only the manufacturer’s replacement line in the cutting head. Do not use any other cutting attachment. To install any other brand of cutting head to this string trimmer can result in serious personal injury.

Never operate unit without the grass deflector in place and in good condition.

Maintain a firm grip on both handles while trimming. Keep string head below waist level. Never cut with the string head located over 30 in. or more above the ground.

This product is intended for infrequent use by homeowners and other occasional users for such general applications as trimming light and heavy vegetation, etc. It is not intended for prolonged use.

Replacing the Spark Arrestor

See Figure 17.

WARNING:

Stop engine, remove spark plug boot, and allow engine and muffler to cool before replacing the spark arrestor. Contact with a hot muffler or engine could cause burns or other serious personal injuries.

Note: Depending on the type of fuel used, the type and amount of lubricant used, and/or your operating conditions, the exhaust port, muffler, and/or spark arrestor screen may become blocked with carbon deposits. If you notice a power loss with your gas powered tool, you may need to remove these deposits to restore performance. We highly recommend that only qualified service technicians perform this service.

The spark arrestor may need to be cleaned or replaced after repeated use. If replacement is necessary, use Toro part number 000998216.

To replace the spark arrestor:

1. Remove the five screws that hold the cover.

Note: Removing these screws requires the use of a T20 and T25 torx screwdriver.

2. Remove the cover.

3. Remove the two screws holding the muffler assembly in place.

In California, new equipment that uses small off-road engines must be designed, built, and equipped to meet the state’s stringent anti-smog standards. In other states, new small off-road engines must be designed, built, and equipped at the time of sale to meet the U.S. EPA regulations for small off-road engines. The small off-road engine must be free from defects in materials and workmanship which cause it to fail to conform with U.S. EPA standards for the first three years of engine use from the date of sale to the ultimate purchaser. Techtronic Industries North America, Inc., must warrant the emission control system on your small off-road engine for the period of time listed above provided there has been no abuse, neglect, or improper maintenance of your small off-road engine.

Your emission control system may include parts such as the carburetor or fuel injection system, the ignition system, catalytic converters, fuel tanks, valves, filters, clamps, connectors, fuel lines, fuel caps, canisters, vapor hoses, and other associated components. Also included may be hoses, belts and connectors, and other emission-related assemblies. For engines less than or equal to 80 cc only the fuel tank is subject to the evaporative emission control warranty requirements of this section. (California Only)

Where a warrantable condition exists, Techtronic Industries North America, Inc., will repair your small off-road engine at no cost to you, including diagnosis, parts, and labor.

MANUFACTURER’S WARRANTY COVERAGE
