IMPORTANT SAFETY INSTRUCTIONS

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 string head or blade will rotate 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 9 m (30 ft. ) away from refueling site before starting engine.

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

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

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.

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

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 line 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 76 cm (30 in.) or more above the ground.

SPECIFIC SAFETY RULES FOR BRUSH

CUTTER AND BLADE USE

After engine stops, keep rotating blade in thicker weeds or pulpy stalks until it 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 to spin after the engine is stopped or throttle trigger released. Maintain proper control until the blade has completely stopped rotating.

3

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.

Use only the manufacturer’s replacement 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 blade is suited for cutting thicker weeds or pulpy stalks only. Do not use for any other purpose.

Never use the 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 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.

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

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 your body and below waist level.

Never use the brushcutter with the blade located

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

OPERATION

CUTTING TIPS

Avoid hot surfaces by always keeping the tool away from your body.

Keep the trimmer tilted toward the area being cut; this is the best cutting area.

The line trimmer cuts when passing the unit from right to left. This will avoid throwing debris at the operator. Avoid cutting in the dangerous area shown in Fig.19.

Cut all grass from top to down. This will prevent grass from wrapping around the shaft housing and string head which could cause damage from overheating. If grass becomes wrapped around the string head, STOP THE ENGINE, disconnect the spark plug wire, and remove the grass.

Use the tip of line to trim grass; do not force string head into uncut grass.

Wire and picket fences cause extra line wear, even breakage. Stone and brick walls, curbs, and wood may wear line rapidly.

Avoid trees, flowers, stones, walls and other objects which can cause the line breakage.

Check and feed the line regularly to maintain full cutting width and performance.

OPERATING THE BRUSH CUTTER (FIG.20)

OPERATION

Exercise extreme caution when using the blade with this unit.

Blade thrust is the reaction which 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 may 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, Fig.22.

In the event that an unexpected object or woody stock is encountered, this could minimise the blade thrust reaction.

BLADE

The blade is suited only for pulpy weeds and vines.

When the blade becomes dull, it can be turned over to extend the life of the blade. Do not sharpen the blade.

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.

Always hold brushcutter with both hands when operating. Use a firm grip on both handles.

Maintain your grip and balance on both feet.

Position yourself so that you will not be drawn off balance by the kick-back reaction of the cutting blade.

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

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

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

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

Fig. 23

EXTENDING THE CUTTING LINE

Run engine at full throttle.

Tap the knob on hard, bare ground to advance line.

The line advances each time the knob is tapped.

Do not hold the knob on the ground.

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

Fig.23.

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

TO ADVANCE THE CUTTING LINE MANUALLY

Stop the engine and disconnect the spark plug wire. Push the spool retainer down while pulling on cutting lines to manually advance the string.

GRASS DEFLECTOR LINE TRIMMING CUT-OFF

BLADE

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

1. Pull out the spark plug cap and clean the dust in the spark plug area.

2. Screw out the spark plug with the provided socket wrench.

3. Check the ceramic isolation. Replace the spark plug if damaged.

4. Clean the electrodes (metal tip) to refresh the surfaces.

5. Restore the spark plug and its cap.

NOTE: Be careful not to cross-thread the spark plug. Cross-threading will seriously damage the product.

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 recommend that only qualified service technicians perform this service.

MAINTENANCE

IDLE SPEED ADJUSTMENT

WARNING.

The cutting head will move when adjusting the idle speed. Wear all protective clothing and keep all bystanders, children, and pets at least

50 ft. away.

Make adjustments with the unit supported by hand so that the cutting head does not contact the ground or any object. Keep all parts of your body away from the cutting head and muffler. Failure to follow these instructions could result in serious personal injury.

If the cutting attachment turns at idle, the idle speed screw needs adjusting on the engine. Turn the idle speed screw counterclockwise to reduce the idle RPM and stop the cutting attachment movement, Fig.29. If the cutting attachment still moves at idle speed, contact customer support for adjustment and discontinue use until the repair is made.

WARNING.

The cutting attachment should never turn at idle. Turn the idle speed screw counterclockwise to reduce the idle RPM and stop the cutting attachment. Serious personal injury could result from the cutting attachment turning at idle.

FUEL CAP, TANK, AND LINES

WARNING.

Check for fuel leaks. A leaking fuel cap, tank, or line is 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.

STORING THE PRODUCT

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

Clean all foreign material from the unit. 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.
