SPECIFIC SAFETY RULES

This product is intended for infrequent use by homeown - ers and other occasional users for such general applications as trimming light and heavy vegetation, etc. It is not intended for prolonged use. Prolonged periods of opera - tion can cause circulatory problems in the user’s hands due to vibration. For such use, it may be appropriate to use a product having an anti-vibration feature.

SPECIFIC SAFETY RULES FOR TRIMMER USE

Inspect before use. Replace damaged parts. Make sure fasteners are in place and secure. Check for fuel leaks.

Replace string head if cracked, chipped,or damaged in any way. Be sure the string head or blade is properly installedandsecurelyfastened.Failuretodosocancause serious injury.

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

Use only identical replacement line in the cutting head. Do not use any other cutting attachment. To install any othertypeofreplacementlineorcuttingheadtothisstring trimmer can result in serious personal injury. Never use, for example, wire or wire-rope, which can break off and become a dangerous projectile.

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

Never useblades,flailingdevices,wire,orropeontrimmer attachment.

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.

SPECIFIC SAFETY RULES FOR ­

BRUSH CUTTER AND BLADE USE

Brushcutterbladescoastafterthr ottletriggerisreleased or engine is stopped. Keep the rotating blade in thicker weeds or pulpy stalks until the blade completely stops.

Do not operate the brush cutter unless the brush cutter guard is firmly secured in place and in good condition.

Use heavy gloves when operating the brush cutter and when installing or removing blades.

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.

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

 A coasting blade	can cause	injury	while it continues

released. Maintain proper control until the blade has completely stopped rotating.

Replaceanybladethathasbeendamaged. Alwaysmake sure blade is installed correctly and securely fastened beforeeachuse.Failuretodosocancauseseriousinjury.

Use only the manufacturer’s replacement Tri-Arc® blade intended for use on this brush cutter. Do not use any other blade. To install any other brand blade or cutting head to this brush cutter can result in serious personal injury.

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.

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 op - erator 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.

Never cut any material over 1/2 in. diameter.

Always wear the shoulder har ness when using the brush cutter and adjust to a comfortable operating position. Maintain a firm grip on both handles while cutting with a blade. Keep the blade away from your body and below waist level.

Never use the brush cutter with the blade located 30 in. or more above the ground level.

OPERATING THE POWER HEAD

See Figure 5.

WARNING:

Engine housing can become hot during power head opera - tion. Do not rest or place your arm, hand, or any body part against the engine housing during power head operation. Only hold the power head with all body parts clear of engine housing. Extended contact with the engine housing could result in burns or other injuries.

8 — English

OPERATION

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.

WARNING:

Extreme care must be taken when using blades to ensure safe operation. Read the safety information for safe operation when using a blade and refer to the safety rules and instructions in your attachment manual.

WARNING:

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

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

See figure 5 for proper operation position with trimmer attachment installed.

Always operate power head at full throttle. If debris becomes wrapped around the attachment, STOP THE ENGINE, disconnect the spark plug wire, and remove the debris. Prolonged use at partial throttle will result in lubricant dripping from the muffler.

WARNING:

Always hold the attachment away from the body keeping clearance between the body and the product. Any contact with the attachment cutting head can result in burns and/or other serious personal injury.

BLADE THRUST

Exercise extreme caution when using a blade attachment 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 with the brush cutter from the right to the left. In the event an unexpected object or woody stock is encountered, this practice could minimize the blade thrust reaction.

STARTING AND STOPPING

MAINTENANCE

FUEL CAP, TANK, AND LINES

WARNING:

Check for fuel leaks. A leaking fuel cap, tank, or lines are a fire hazard and must be replaced immediately. If you find any leaks, correct the problem before using the product. Failure to do so could result in a fire that could cause serious personal injury.

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, the check valve may be faulty or filter clogged. Replace the fuel cap if required.

SPARK PLUG REPLACEMENT

The spark plug for this engine may be replaced using a Ryobi accessory spark plug or a Champion RCJ6Y. The spark plug gap should be set at .025 in. Use an exact replacement and replace annually.
