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

n Never operate this unit on the operator's left side.

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

n Keep all bystanders, children, and pets at least 15 m (50 ft.) away. n Do not operate this unit when you are tired, ill, or under the influence of alcohol, drugs, or medication. n Do not operate in poor lighting.

n Keep firm footing and balance. Do not overreach.

Overreaching can result in loss of balance or exposure to hot surfaces.

n Keep all parts of your body away from any moving part. n To avoid hot surfaces, never operate the unit with the bottom of the engine above waist level.

GENERAL SAFETY RULES

n Do not touch area around the muffler or cylinder of the unit, these parts get hot from operation. n Always stop the engine and remove the spark plug wire before making any adjustments or repairs except for carburetor adjustments. n Inspect the unit before each use for loose fasteners, fuel leaks, etc. Replace any damaged parts before use. n The string head or blade will rotate during carburetor adjustments. n 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 the 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.

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

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

Wipe up any fuel spillage. Move 9 m (30 ft. ) away from refueling site before starting engine.

n Stop the engine and allow to cool before refueling or storing the unit. n Allow the engine to cool; empty the fuel tank and secure the unit from moving before transporting in a vehicle.

SPECIFIC SAFETY RULES FOR TRIMMER

USE

n Replace string head if cracked, chipped, or damaged in any way. Be sure the string head or blade is properly installed and securely fastened. Failure to do so can cause serious injury. n Make sure all guards, straps, deflectors and handles are properly and securely attached.

n Use only the manufacturer's replacement string 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.

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

n Maintain a firm grip on both handles while trimming.

Keep string head below waist level. Never cut with the string head located over 76 cm (30 in.) or more above the ground.

SPECIFIC SAFETY RULES FOR BRUSHCUT-

TER AND BLADE USE

n After engine stops, keep rotating blade in thicker weeds or pulpy stalks until it stops.

n Do not operate the brushcutter unless the brushcutter guard is firmly secured in place and in good condition.

n Use heavy gloves when operating the brushcutter and when installing or removing blades.

n Always stop the engine and remove the spark plug wire before attempting to remove any obstruction caught or jammed in the blade or before removing and installing the blade.

n Do not attempt to touch or stop the blade when it is rotating.

n A coasting blade can cause injury while it continues to spin after the engine is stopped or throttle trigger released.

Maintain proper control until the blade has completely stopped rotating.

SPECIFIC SAFETY RULES

n Replace any blade that has been damaged. Always make sure blade is installed correctly and securely fastened before each use. Failure to do so can cause serious injury. n Use only the manufacturer's replacement Tri-Arc® blade intended for use on this brushcutter. Do not use any other blade. To install any other brand blade or cutting head to this brushcutter can result in serious personal injury.

n The Tri-Arc® blade is suited for cutting thicker weeds or pulpy stalks only. Do not use for any other purpose. Never use the Tri-Arc® blade to cut woody brush.

n Exercise extreme caution when using the blade with this unit. Blade thrust is the reaction that may occur when the spinning blade contacts anything it cannot cut. This contact may cause the blade to stop for an instant, and suddenly “thrust” the unit away from the object that was hit. This reaction can be violent enough to cause the operator to lose control of the unit. 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. For cutting ease and safety, approach the weeds being cut from the right to the left. In the event an unexpected object or woody stock is encountered, this could minimize the blade thrust reaction.

n Never cut any material over 13 mm (1/2 in.) diameter.

n Always wear the shoulder harness when using the brushcutter and adjust to a comfortable operating position. Maintain a firm grip on both handles while cutting with a blade.

Keep the blade away from body and below waist level. n Never use the brushcutter with the blade located 76 cm

(30 in.) or more above the ground level.

OPERATION

FUELING AND REFUELING THE TRIMMER

FUEL MIXTURE

This product is powered by a 2-cycle engine and requires premixing gasoline and 2-cycle oil. Pre-mix unleaded gasoline and 2-cycle engine oil in a clean 1 gallon container approved for gasoline.

Recommended fuel: This engine is certified to operate on unleaded gasoline intended for automotive use.

Mix a high quality 2-cycle engine oil at 2.6 oz. per gallon

(US).

Do not use automotive oil or 2-cycle outboard oil.

DO NOT mix quantities larger than usable in a 30 day period.

WARNING:

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

Hold the trimmer with the right hand on the rear handle and the left hand on the front handle. Keep a firm grip with both hands while in operation. Trimmer should be held at a comfortable position with the rear handle about hip height.

Always operate trimmer at full throttle. Cut tall grass from the top down. This will prevent grass from wrapping around the shaft housing and string head which may cause damage from overheating. If grass becomes wrapped around the string head, STOP THE ENGINE, disconnect the spark plug wire, and remove the grass. Prolonged cutting at partial throttle will result in oil dripping from the muffler.

HIGH QUALITY 2-CYCLE ENGINE OIL

GASOLINE OIL

1 gallon (US) 2.6 oz.

1 Liter 20 cc (20 ml)

FILLING TANK

1. Clean surface around fuel cap to prevent contamination.

2. Loosen fuel cap slowly. Rest the cap on a clean surface.

3. Carefully pour fuel into the tank. Avoid spillage.

4. Prior to replacing the fuel cap, clean and inspect the gasket.

5. Immediately replace fuel cap and hand tighten. Wipe up any fuel spillage.

NOTE: It is normal for smoke to be emitted from a new engine after first use.

WARNING:

Always shut off engine before fueling. Never add fuel to a machine with a running or hot engine. Move at least

30 ft. (9 m) from refueling site before starting engine. Do not smoke!

OPERATING THE TRIMMER

See Figure 15.

WARNING:

Always position the unit on the operator's right side. The use of the unit on the operator's left side will expose the user to hot surfaces and can result in possible burn injury.

Page 15

OPERATION

TO ADVANCE THE CUTTING LINE

String advance is controlled by tapping the string head on grass while running engine at full throttle.

1. Run engine at full throttle.

2. Tap the spool retainer on ground to advance string. The string advances each time the spool retainer is tapped.

Do not hold the spool retainer on the ground.

NOTE: The line trimming cut-off blade on the grass deflector will cut the line to the correct length.

NOTE: If the string is worn too short you may not be able to advance the string by tapping it on the ground. If so, stop the engine, and manually advance the string.

TO ADVANCE THE CUTTING LINE MANUALLY

Push the spool retainer down while pulling on string(s) to manually advance the string.

CUTTING TIPS

See Figures 16 -17.

n Keep the trimmer tilted toward the area being cut; this is the best cutting area. n The curved shaft trimmer cuts when passing the unit from right to left. The straight shaft trimmer cuts when passing the unit from left to right. This will avoid throwing debris at the operator. Avoid cutting in the dangerous area shown in illustration.

n Use the tip of string to do the cutting; do not force string head into uncut grass. n Wire and picket fences cause extra string wear, even breakage. Stone and brick walls, curbs, and wood may wear string rapidly. n Avoid trees and shrubs. Tree bark, wood moldings, siding, and fence posts can easily be damaged by the string.

GRASS DEFLECTOR LINE TRIMMING CUT-OFF

BLADE

See Figure 18.

The trimmer is equipped with a line trimming cut-off blade on the grass deflector. For best cutting, advance string until it is trimmed to length by the cut-off blade. Advance the string whenever you hear the engine running faster than normal, or when trimming efficiency diminishes. This will maintain best performance and keep the string long enough to advance properly.

OPERATION

OPERATING THE BRUSHCUTTER


Hold the brushcutter with the right hand on the rear handle and the left hand on the “J” Barrier Handle. Keep a firm grip with both hands while in operation. Brushcutter should be held at a comfortable position with the rear handle about hip height. Maintain your grip and balance on both feet. Position yourself so that you will not be drawn off balance by the kickback reaction of the cutting blade.

Adjust the shoulder harness to position the brushcutter at a comfortable operating position and to assure that the shoulder harness will reduce the risk of operator contact with the blade.

TRI-ARC® BLADE

The Tri-Arc® blade is suited only for thicker weeds and pulpy stalks. When the blade becomes dull, it can be turned over to extend the life of the blade. Do not sharpen the Tri-Arc® blade.

Use only Tri-Arc® blade, part number AP04105, available at your local retailer.

CUTTING TECHNIQUE - BLADE

WARNING:

Extreme care must be taken when using blades to ensure safe operation. Read the safety information for safe operation using the blade, refer to “Specific Safety Rules for Brushcutter and Blade Use” earlier in this manual.

n Always hold brushcutter on your right side with both hands when operating. Use a firm grip on both handles.

n Maintain your grip and balance on both feet. Position yourself so that you will not be drawn off balance by the kickback reaction of the cutting blade.

n Inspect and clear the area of any hidden objects such as glass, rocks, concrete, fencing, wire, wood, metal, etc.

n Never use blades near sidewalks, fencing, posts, buildings or other immovable objects.

n Never use a blade after hitting a hard object without first inspecting it for damage. Do not use if any damage is detected.

n The unit is used as a scythe, cutting from the right to the left in a broad sweeping action from side to side.

n Use only the Tri-Arc® blade. To install any other brand blade or cutting head to this brushcutter can result in serious personal injury.

You can often make adjustments and repairs described here.

For other repairs, have the trimmer serviced by an authorized service dealer.

SPOOL REPLACEMENT

NEW PREWOUND SPOOL


If replacing string only, refer to “String Replacement” later in this manual.

Use only monofilament string. Use original manufacturer's replacement string for best performance.

String Diameter:

CS30 - .080 in. (2.0 mm)

SS30 - .095 in. (2.4 mm)

BC30 - .095 in. (2.4 mm)

1. Stop the engine, disconnect the spark plug wire. Hold the string head and unscrew the spool retainer.

To remove the spool retainer:

Turn the spool retainer counterclockwise for models

CS30.

Turn the spool retainer clockwise for models SS30 and

BC30.

2. Remove the empty spool from the string head. Keep the spring attached to the spool.

3. To install the new spool, make sure the two strings are captured in the slots opposite each other on the new spool. Make sure the ends of each string is extended approximately 6 in. (152 mm) beyond each slot.

4. Thread the strings into the eyelets in the string head.

Carefully push the spool into the string head (gently pull the strings to the outside if necessary). When the spool is positioned in the string head, grasp the strings and pull sharply to release them from the slots in the spool.

5. Push down and turn the spool counterclockwise until it no longer turns. Hold the spool down and rotate clockwise a small amount. Release the spool. The spool should be locked down in the string head. If not, hold down and rotate until locked.

MAINTENANCE

CLEANING THE EXHAUST PORT AND

MUFFLER

NOTE: Depending on the type of fuel used, the type and amount of oil 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 recommended that only qualified service technicians perform this service.

SPARK ARRESTOR

The spark arrestor must be cleaned or replaced every 25 hours or yearly to ensure proper performance of your product.

Spark arrestors may be in different locations depending on the model purchased. Please contact your nearest service dealer for the location of the spark arrestor for your model.

REPLACING AND CLEANING AIR FILTER


For proper performance and long life, keep air filter clean.

1. Remove the air filter cover by turning the knob counterclockwise while gently pulling on the cover.

FUEL CAP

WARNING:

A leaking fuel cap is a fire hazard and must be replaced immediately.

The fuel cap contains a non-serviceable filter and a check valve. A clogged fuel filter will cause poor engine performance. If performance improves when the fuel cap is loosened, check valve may be faulty or filter clogged. Replace fuel cap if required.

SPARK PLUG

This engine uses a Champion RCJ-6Y or NGK BPMR7A spark plug with 0,63 mm (.025 in.) electrode gap. Use an exact replacement and replace annually.

STORAGE (1 MONTH OR LONGER)

1. Drain all fuel from tank into a container approved for gasoline. Run engine until it stops.

2. Clean all foreign material from the trimmer. Store it in a well-ventilated place that is inaccessible to children. Keep away from corrosive agents such as garden chemicals and de-icing salts.

3. Abide by all ISO and local regulations for the safe storage and handling of gasoline. Excess fuel should be used up in other 2-cycle engine powered equipment.

WARRANTY

THE FOLLOWING CARB STATEMENT ONLY APPLIES TO MODEL NUMBERS REQUIRED TO

MEET (CARB) REQUIREMENTS.

RYOBI TECHNOLOGIES INC. LIMITED WARRANTY FEDERAL AND CALIFORNIA EMISSION

CONTROL SYSTEMS NONROAD AND SMALL OFF-ROAD ENGINES

The U.S. Environmental Protection Agency (EPA), the California Air Resources Board (CARB), and Ryobi Technologies Inc. are pleased to explain the Emission Control System Warranty on your nonroad or small off-road engine. In California, new small off-road engines must be designed, built and equipped to meet the state's stringent anti-smog standards. In other states, new 2000 and later model year nonroad engines must be designed, built and equipped, at the time of sale, to meet the U.S. EPA regulations for small nonroad engines.

The nonroad 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 two years of engine use from the date of sale to the ultimate purchaser. Ryobi Technologies Inc. must warrant the emission control system on your nonroad or small off-road engine for the period of time listed above provided there has been no abuse, neglect, or improper maintenance of your nonroad or small off-road engine.

Your emission control system may include parts such as the carburetor or fuel injection system, the ignition system, the catalytic converter. Also included may be hoses, belts, and connectors and other emission related assemblies.

Where a warrantable condition exists, Ryobi Technologies Inc. will repair your nonroad or small off-road engine at no cost to you, including diagnosis (if the diagnostic work is performed at an authorized dealer), parts, and labor.

MANUFACTURER'S WARRANTY COVERAGE:

The 1995 and later small off road engines are warranted for two years in California. In other states, 1997 and later model year nonroad engines are also warranted for two years. If any emission-related part on your engine is defective, the part will be repaired or replaced by

Ryobi Technologies Inc. free of charge.

OWNER'S WARRANTY RESPONSIBILITIES

(a) As the nonroad or small off-road engine owner, you are responsible for the performance of required maintenance listed in your owner's manual. Ryobi Technologies Inc. recommends that you retain all receipts covering maintenance on your nonroad or small off-road engine, but Ryobi Technologies Inc., cannot deny warranty solely for the lack of receipts or for your failure to ensure the performance of all scheduled maintenance. Any replacement part or service that is equivalent in performance and durability may be used in non-warranty maintenance or repairs, and shall not reduce the warranty obligations of the engine manufacturer.

(b) As the nonroad or small off-road engine owner, you should be aware, however, that Ryobi Technologies Inc., may deny you warranty coverage if your nonroad or small off-road engine or a part has failed due to abuse, neglect, improper maintenance or unapproved modifications.

(c) You are responsible for presenting your nonroad or small off-road engine to a Ryobi Technologies Inc., service dealer as soon as a problem exists. The warranty repairs should be completed in a reasonable amount of time, not to exceed 30 days.

Ryobi Technologies Inc. also warrants to the initial purchaser and each subsequent purchaser that your nonroad or small off-road engine is free from defects in materials and workmanship which cause the engine to fail to conform with applicable regulations for a period of two years. The 1995 and later small off road engines are warranted for two years in California. In all other states for 1997 and later model years, EPA requires manufacturers to warrant non-road engines for two years.

Ryobi Technologies Inc. shall remedy warranty defects at any authorized Ryobi Technologies Inc. engine dealer or warranty station.

Any authorized work done at an authorized dealer or warranty station shall be free of charge to the owner if such work determines that a warranted part is defective. Any manufacturer-approved or equivalent replacement part may be used for any warranty maintenance or repairs on emission-related parts, and must be provided free of charge to the owner if the part is still under warranty. Ryobi Technologies Inc. is liable for damages to other engine components caused by the failure of a warranted part still under warranty.

The California Air Resources Board's Emission Warranty Parts List specifically defines the emission-related warranted parts. (EPA's regulations do not include a parts list, but EPA considers emission-related warranted parts to include all the parts listed below.)

These warranted parts are: Carburetor, Spark Plug, Ignition, Air Filter and Fuel Filter.
