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. Do not touch area around the muffler or cylinder of the trimmer/brushcutter, these parts get hot from operation. 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 opera-ting 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. If you experience any of the symptoms of this condition, immediately discontinue use and see your physician about these symptoms. Keep the tool well maintained, fasteners tightened and worn parts replaced. Mix and store fuel in a container approved for fuel. Mix fuel outdoors where there are no sparks or flames. Wipe up any fuel spillage. Move 9 m 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.

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 line in the cutting head. Do not use any other cutting attachment. 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 or more above the ground.

After engine stops, keep rotating blade in heavy grass or pulpy weeks until it stops. Do not operate the brushcutter unless the blade guard is firmly secured in place and in good condition. Use heavy gloves while 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. 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 brushcutter. Do not use any other blade. The blade is suited for cutting pulpy weeds and vines 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 diameter. Always wear the shoulder strap 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. Never use the brushcutter with the blade located 76 cm or more above the ground level. Cover the blade with the blade protector before storing the unit, or during transportation. Always remove the blade protector before using the unit. If not removed, the blade protector could become a thrown object as the blade begins to turn.

English OPERATION Clean up spilled petrol immediately.

1 Litre 2 Litres 3 Litres 4 Litres 5 Litres This product is powered by a 2-stroke engine and requires pre-mixing petrol and 2-stroke oil. Pre-mix unleaded petrol and 2-stroke engine oil in a clean container approved for petrol. This engine is certified to operate on unleaded petrol intended for automotive use with an octane rating of 87 ([R + M] / 2) or higher. Do not use any type of pre-mixed petrol / oil from fuel service stations, this includes the pre-mixed petrol / oil intended for use in mopeds, motorcycles, etc. Use synthetic 2-stroke oil only. Do not use automotive oil or 2-stroke outboard oil. Mix the 2-stroke oil into the petrol. This is a 30:1 ratio. Mix the fuel thoroughly and also each time before fueling. Mix in small quantities. Do not mix quantities larger than usable in a 30 day period. Synthetic 2-stroke oil containing a fuel stabilizer is recommended.

30:1 OPERATING THE TRIMMER (Fig. 8) Hold the trimmer with the right hand on the trigger handle and the left hand on the left handle. Keep a firm grip with both hands while in operation. Trimmer should be held at a comfortable position with the trigger 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. CUTTING TIPS (Fig. 9)

Clean surface around fuel cap to prevent contamination. Loosen fuel cap slowly to release pressure and to keep fuel from escaping around the cap. Carefully pour fuel mixture into the tank. Avoid spillage. Prior to replacing the fuel cap, clean and inspect the gasket. Immediately replace fuel cap and hand tighten. Wipe up any fuel spillage. Move 9 m away from refueling site before starting engine. Note: It is normal for smoke to be emitted from a new engine during and after first use.

Keep the trimmer tilted towards the area being cut; this is the best cutting area (27). Do not cut in dangerous cutting area (28). Use the tip of string to do the cutting; do not force string head into uncut grass. Wire and picket fences cause extra string wear, even breakage. Stone and brick walls, kerbs and wood may wear string rapidly. Avoid trees and shrubs. Tree bark, wood mouldings, cladding and fence posts can easily be damaged by the string. OPERATING THE BRUSHCUTTER (Fig. 10-11) Hold the brushcutter with the right hand on the trigger handle and the left hand on the left handle. Keep a firm grip with both hands while in operation. Brushcutter should be held at a comfortable position with the trigger 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 kick-back reaction of the cutting blade. WARNING Always shut off engine before fueling. Never add fuel to a machine with a running or hot engine. Move at least 9 m from refueling site before starting engine. Do not smoke! Adjust the shoulder strap to position the brushcutter at a comfortable operating position and to assure that the shoulder strap will reduce the risk of operator contact with the blade. 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. In the event that an unexpected object or woody stock is encountered, this could minimise the blade thrust reaction.

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.

Lay trimmer on a flat, bare surface. Move ignition switch to the “I” position. Choke lever should already be in the open choke ( ) position. Pull the starter rope until unit runs. TO STOP THE ENGINE: To stop the engine, depress the ignition switch to the “O” position. 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.

Lay trimmer on a flat, bare surface. Move ignition switch to the “I” position. Push primer bulb (30) 5 times. Note: Do not squeeze the throttle trigger (21) before engine starts. Squeezing the throttle trigger at this time will prevent the unit from starting. Move the lever (31) up to close choke ( ). Pull the starter grip until engine starts. Move the lever down to open choke ( ). Allow the engine to warm up for a few minutes before using. MAINTENANCE WARNING Use only original manufacturer's replacement parts, accessories and attachments. Failure to do so can cause possible injury, poor perfor-mance and may void your warranty. 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.

STARTING AND STOPPING (Fig. 12 and Fig. 16) WARNING Never start or run the engine inside a closed or poorly ventilated area; breathing exhaust fumes can kill. The cutting attachment must not work in idle mode. If this requirement is not satisfied, the clutch has to be adjusted or the machine needs an urgent maintenance by a qualified technician. You may make adjustments and repairs described here. For other repairs, have the trimmer serviced by an authorized service agent. Consequences of improper maintenance may include excess carbon deposits resulting in loss of performance and discharge of black oily residue dripping from the muffler. Make sure all guards, straps, deflectors and handles are properly and securely attached to avoid the risk of personal injury. STRING REPLACEMENT Use only 2.7mm diameter string. Stop the engine, disconnect the spark plug wire.

FUEL CAP WARNING A leaking fuel cap is a fire hazard and must be replaced immediately. Hold the string head and unscrew from the unit. Turn clockwise. Push the button on the string head and pull the string out. Push the button and push the new line through the eyelet of the string head. 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 the filter clogged. Replace fuel cap if required. BLADE PROTECTOR (Fig. 13) Always place the blade protector (32) on the blade when the unit is not in use. Wear gloves and be cautious when handling the blade. SPARKING PLUG This engine uses a TORCH L7RTC with 0.6 - 0.7mm electrode gap. Use an exact replacement and replace annually. Note: Always remove the blade protector before using the unit. If not removed, the blade protector could become a thrown object as the blade begins to turn. STORAGE (1 MONTH OR LONGER)

Depending on the type of fuel used, the type and amount of oil used, and/or your operating conditions, the exhaust port and muffler may become blocked with carbon deposits. If you notice a power loss with your petrolpowered tool, a qualified service technician will need to remove these deposits to restore performance.

REPLACING AND CLEANING AIR FILTER

(Fig. 14) Drain all fuel from tank into a container approved for petrol. Run engine until it stops. 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. Cover the blade with the blade protector before storing the unit, or during transportation. Abide by all ISO and local regulations for the safe storage and handling of petrol. Excess fuel should be used up in other 2-cycle engine-powered equipment. For proper performance and long life, keep air filter clean.

Remove the air filter cover by unscrewing the screw on the air filter cover. Remove the holding plate in the air filter box. Remove the filter (33), clean it in warm soapy water. Rinse and let dry completely. For best performance, replace annually. Reinstall the filter. Replace the holding plate. Replace the air filter cover and tighten the screw.
