While working with the hedge trimmer, wear protective spectacles or a visor in order to prevent injuries to the eyes. (3) Wear effective hearing protection in order to prevent damage to the hearing (hearing protector muffs, earp- lugs, etc.). (3) We strongly recommend that the operator wears work overalls. (4) Special gloves made of thick leather are a component of the prescribed equipment, and they must be worn when working with the hedge trimmer.(4) When working with the hedge trimmer, always wear robust shoes with non-slip soles. Such shoes protect from injuries, and provide a secure grip. (4) (4) OPERATION Safety instructions relating to operation Ensure that no children or other persons are present within (5) a working range of 15 m; in addition beware of animals in the working range. Confirm the operational safety of the hedge trimmer before each use. Confirm that the throttle lever works correctly. Ensure that the throttle lever can be moved smoothly and ea- sily. Confirm that the throttle lever locking mechanism works correctly. Ensure that the handles are clean and dry, and confirm that the ON/OFF switch works cor- rectly. Keep the handles free from oil and fuel. Start the hedge trimmer only as specified in the in- structions for use. (5)en Operation 30 163-55 / 163-70 WARNING! Do not start the motor in any other way (6) ! Use the hedge trimmer for its designated purpose only. Start the motor of the hedge trimmer only when the hedge trimmer is fully assembled. Operation of the hedge trimmer is permitted only when all equipment specified for its operation has been fitted to it. (6) Before starting the hedge trimmer, ensure that blade is not touching any object e.g. branches, stones, etc. Stop the motor immediately if there are any problems with it. While operating the hedge trimmer, firmly hold both the front and rear handles by placing your fin- gers around the handles. Ensure that the handles are clean and free of moisture, oil, and lubricants. Always ensure a stable, balanced stance. This machine must be used only in the open air. Pay continuous attention to the working environment, and stay prepared for possible dangerous situations of which you may not be aware because of the noise created by the motor. Always operate the hedge trimmer in such a way that you do not inhale the exhaust fumes. Never run the motor in enclosed spaces (danger of asphyxiation and gas poisoning). Carbon monoxide is an odourless gas. Ensure that there is sufficient ventilation at all times. Stop the motor when you take a break or when you are leaving the hedge trimmer unsupervised. Place the hedge trimmer in a secure location in a safe place where it cannot endanger people, and where ignition of flammable materials and damage to the machine cannot occur. Never place the hot hedge trimmer on dry grass or other flammable materials. Always keep the motor and silencer free of trimmings, leaves, and excess lubricant, in order to avoid the danger of a fire. Never operate the motor if the exhaust silencer is damaged. (7) Stop the motor before transporting the machine. (7) Stop the motor before the following activities: – Removing a blockage, – carrying out inspections, maintenance work, or other work on the machine. When transporting in a vehicle, lay the hedge trimmer down in a safe position, so that leakage of fuel is avo- ided. Before transporting the hedge trimmer, ensure that the fuel tank is completely empty, so that leakage of fuel is avoided. Before transporting or storage, always place the cover on the cutting blade. Before you start cutting with the hedge trimmer, in- spect the working area for wires, string, glass, and other foreign bodies which could come into contact with the cutting blade.

Maintenance Electric shock: You must beware of all types of electric wiring and electric fences. Examine the complete working area for electric wires and cables before using the hedge trimmer. When starting the motor, and during operation, you must avoid any contact with the cutting blade. During operation, all protective devices provided with the machine, such as covers, must be cor- rectly attached to the machine.Operation 441662_b 31 Remove sand, stones, nails, wires, etc. from the working area. Foreign bodies may damage the cutting blade. Before cutting the hedge, cut off branches of 8 mm or thicker, using branch shears. Before starting to cut, make sure that the cutting knives have reached their full working speed. After releasing the throttle lever, there is a short period before the cutting knives come to a stop. Do not operate the hedge trimmer at a high idling speed. If the idling speed is set too high, it is no longer possible to adjust the speed of the cutting knives by means of the throttle lever. During the cutting process, hold the hedge trimmer in such a way that the blade creates an angle between 15° and 30° with the cutting line. Take particular care when cutting hedges close to wire fences. Ensure that the cutting blade does not touch any hard objects such as wire fences, stones, or the ground. If such objects are touched, cutting knives may burst, jerk, or break off. (18) If the cutting blade makes contact with stones or other hard objects, switch off the motor imme- diately and examine the blade for damage. Replace a damaged cutting knife before continuing the work. Take regular breaks. solo by AL-KO recommends taking a break of 10 to 20 minutes after 50 minutes of cutting work. Always try to operate the hedge trimmer with the minimum emission of sound and pollutants. In particular, confirm that the carburettor is set correctly, and comply with the prescribed mixing proportions of fuel and oil. Never attempt to remove jammed material while the cutting knives are in motion. Switch the ma- chine off, put it down, and only then remove the jammed material.en Operation 32 163-55 / 163-70 Filling (7) (8) (9) Stop the motor (7)before filling the tank, maintain an appropriate distance from open flames, (8) and do not smoke. Never fill the machine while the motor is running or hot. Avoid skin contact with mineral oil products. Do not inhale fuel vapours. When filling, always wear protec- tive gloves. Change and clean protective clothing re- gularly. In order to avoid ground contamination (environmen- tal protection), ensure that no fuel or oil enters the soil. Wipe spilt fuel off the hedge trimmer immediately. Al- low textiles used to wipe off fuel to dry in a well venti- lated place before disposing of them. Otherwise, sud- den self-ignition may occur. Ensure that your clothing does not come into contact with fuel. If fuel has got onto your clothing, change it immediately (danger!). Check regularly that the cap of the fuel tank is positio- ned correctly. Screw on the tank cap to the correct tightness. Move at least 3 m away from the filling location before starting the motor. (9) Never fill the machine in enclosed spaces. Fuel va- pours may gather at ground level, and thereby result in a deflagration or even an explosion. Transport and store fuel exclusively in containers ap- proved for that purpose. Ensure that children have no access to stored fuel. Carefully clean the area around the tank cap so that no dirt enters the fuel tank. Unscrew the cap and fill the tank with fuel. To filter the fuel, use a funnel with an appropriate filter insert. Screw on the tank cap again by hand. After fuelling, clean the area around the cap and the tank. You must wipe off spilt fuel (danger of fire). (13)Operation 441662_b 33 Fuel/oil mixture The hedge trimmer is powered by a two-stroke motor with a high level of performance. This motor is operated using a mixture of fuel and two- stroke oil. The motor is designed for lead-free regular petrol with an octane rating of ROZ 91. If this fuel is not available, you can use a fuel with a higher octane rating. This does not damage the motor, but the operating behaviour may be poorer. Similar problems arise if leaded fuel is used. In order to achieve optimum operation of the motor, and to protect your health and the environment, only lead-free fuel should be used. (11) The motor is lubricated by the two-stroke oil which is mixed with the fuel. The motor is designed for operation with solo by AL-KO two-stroke oil in a mix ratio of 40:1 (environmen- tal protection). The low mix ratio guarantees minimum pol- lutant emission simultaneously with long working life and reliable operation. The mix ratio of 40:1 (solo by AL-KOtwo- stroke oil) must be complied with, otherwise reliable opera- tion of the hedge trimmer cannot be guaranteed. The correct mix ratio: Carburettor fuel: Prescribed two-stroke oil = 40: 1 or two-stroke oil from another manufacturer = 25: 1 recom- mended (12) ADVICE To prepare the mixture, in an approved container which fulfils or exceeds all locally app- licable requirements, first mix the whole amount of oil with half the required amount of fuel. Then add the rest of the fuel. Mix the mixture thoroughly before adding it to the tank of the hedge trimmer. In order to ensure reliable operation, do not add more motor oil than specified. Otherwise, the result is just the creation of more combustion residue which pollutes the environment and blocks the exhaust duct and the silencer. In addition, the fuel consumption rises and the performance decreases. Handling mineral oil products Extreme care is required when handing fuels. Fuels may contain substances which are similar to sol- vents. Refuel the machine exclusively in a well ventilated location in the open air. Do not inhale the fuel vapours, and avoid any skin contact with fuels and oils. If the skin comes into repeated contact with such substances over an extended period of time, it dries out. This can result in a very wide number of skin disorders. There have also been reports of allergic reac- tions. Eye irritations can occur if oils, fuels, etc. get into the eyes. If this occurs, flush the eyes immediately with clean water. If the eye irritations continue, contact a doc- tor immediately.en Operation 34 163-55 / 163-70 Adjusting the angle of the rear handle The rear handle can be turned up to 90° to the right or left, and locked. How to adjust the angle: 1 Pull the release lever (19A), in order to release the locking for the handle 2 Turn the handle to the desired angle between 0° and 90°. 3 Ensure that the release lever (19A) returns to its origi- nal position, and that the handle lock has engaged. (19) CAUTION! Do not actuate the throttle lever while the handle lock is released. Do not release the handle lock during cutting work. Starting the machine Move at least 3 m away from where refuelling took place. Place the hedge trimmer on a clean base. Ensure that the cutting blade does not come into con- tact with the ground or other objects. Cold start: If the motor is cold, or has been switched off for more than 5 minutes, and after refuelling. 2 Gently press the starter pump several (7 to 10) times (15B), until fuel enters the starter pump. (15)

Bring the choke lever (16C) into position . (16)Operation 441662_b 35 4 Hold the machine firmly, pointing downwards, so that you do not lose control when starting the motor using the pull-cord. Failure to comply with this can result in a sudden jerk or in contact with the cutting blade, and thus to severe injury, material damage, and/or da- mage to the machine. 5 Pull the starter handle slowly by 10 to 15 cm until you feel resistance. 6 Pull strongly on the starter handle. In doing so, you feel resistance, and the motor starts. 7 Let the motor run for about one minute at an appro- priate speed before applying full power. (6) Stopping the machine 1 Completely release the throttle lever. 2 Set the ON/OFF button to "O" (off). The motor runs down and stops. (7)

MAINTENANCE AND CARE

Maintenance instructions Be considerate of the environment and of your neigh- bours. Always try to operate the hedge trimmer at the lowest possible noise and pollutant emissions. Above all, confirm that the carburettor is set correctly. Clean the hedge trimmer regularly, and check that all bolts and nuts are firmly tightened. Never maintain or store the hedge trimmer in proximity to open flames or sparks (fire hazard). (10) Switch off the motor and disconnect the spark plug lead before cleaning/replacing/sharpening the cutting blade or carrying out other maintenance work. Store the hedge trimmer in a well ventilated location. The storage must be high enough or lockable, in order that children cannot access the hedge trimmer. Undertake only those repairs on the hedge trimmer for which you are sufficiently qualified. Never straighten or weld damaged cutting machines. With the motor switched off, check the cutting blade regularly for damage. Ensure that cutting tools are always correctly sharpened. The knives are sharp; therefore always wear safety gloves when handling and sharpening the knives.en Maintenance and care 36 163-55 / 163-70 CAUTION! Comply with all accident prevention measures laid down by the relevant trade associations and authorities and recommended by insurers. Do not undertake any changes whatsoever to the hedge trimmer, because this would put your safety at risk. The operator may carry out only the maintenance and repair tasks described in these instructions for use. All other maintenance work must be carried out by authorised maintenance personnel. Use only original replacement parts and original accessory parts which you have obtained from authori- sed solo by AL-KO service centres. The use of unapproved accessory parts and tools creates an increased risk of accidents and injuries. For personal injury and/or material damage caused by the use of unapproved replacement and/or accessory parts, solo by AL-KO accepts no liability. Sharpening the knives If the knives have become blunted, and no longer cut well, sharpen the positions on the blades which are cross-hatched in the diagram (20-3). Do not sharpen the contact (slide) surfaces of the upper and lower knives. (20-1) Flat grinders (20-2) Cutting cross-section Switch off the motor, disconnect the the spark plug lead, and ensure that the cutting blade and the knife are secured before you grind the knives. Wear gloves, safety spectacles, etc. Do not grind off too much material. That would re- move the hardened layer, and the knives would be- come blunt very quickly when used. (20) Resetting the separation between upper and lower knives Grind the upper/lower knives. If you do not obtain a clean cut, even though the knives are sharp enough, set the distance between the knives as follows: 1 Loosen the bolts in order to remove the cutting blade from the machine. 2 Loosen the nut (21-1)by means of a ring or open-ja- wed spanner. 3 Slightly tighten the holding bolt (21-2) by means of a Torx spanner, until you feel resistance, and then loo- sen the holding bolt again by a quarter-turn. (21)Maintenance and care 441662_b 37 4 Hold the holding bolt (21-2) in place, and tighten the nut (21-1) securely. 5 Apply a little oil to the contact surfaces of the knives. 6 Start the motor and run it for one minute, during which time you repeatedly accelerate and decelerate. 7 Measure the time which the knives require to come to a stop after releasing the throttle lever. If this takes two seconds or longer, stop the motor and repeat steps 2 to 7. 8 Stop the motor and touch the surface of the knives. If the knives are not too hot to be touched, then the setting is correct. If the knives are too hot to be touched, loosen the holding bolt slightly (2), and repeat steps 6 to 8. 9 Re-attach the cutting blade to the machine, using the bolts. ADVICE Stop the motor and ensure that the cutting knives have come to a complete stop before you adjust settings. There are slots in the knives close to bolt (21-2) . If these slots are blocked with dust, clean them. Checking and adjusting the idling speed When the motor is idling, the cutting knives should be at a standstill. The idling speed should be set to 3,100 min-1 (rpm). Use the idling speed screw to set the idling speed (when the motor is idling, the cutting knives must be at a standstill). – If the knives move during idling, turn the idling speed screw anticlockwise in order to reduce the idling speed. – If the motor stops while idling, turn the idling speed screw clockwise in order to increase the id- ling speed. If the cutting knives continue to run even after set- ting the idling speed, contact your authorised service centre. – The clutch should engage at 4,000 min-1 (rpm) at the earliest. – Check the ON/OFF switch, the handle grip re- lease lever, and the throttle lever for correct func- tioning. (22) Cleaning the air filter DANGER! Open flames are strictly forbidden.en Maintenance and care 38 163-55 / 163-70 Check and clean the air filter every day, or after 15 opera- ting hours at the most. Turn the choke lever so that it is completely closed, and keep the carburettor free of dust and dirt. Loosen the holding bolt (23-1). Remove the air filter by pulling the air filter cover (on the filter's rear side) forwards. If the insert (foam) (23-2) is contaminated with oil, forcefully press out the insert. In the case of heavy contamination: (23) – Remove the insert (foam) (23-2), immerse it in hot water or in water and diluted neutral cleaning agent, and then allow the insert to dry fully. – Clean the insert (felt) (23-3) with petrol, and allow the insert to dry fully. Let the inserts dry fully before you re-install the air filter. If the inserts are not dried sufficiently, difficulties in starting the motor may arise. Use a cleaning rag to wipe off oil adhering around the air filter. Fit the air filter cover immediately after cleaning, and secure the cover by means of the holding screw (23-1). ADVICE Important points when handling the air filter inserts Clean the inserts several times per day if excessive dust adheres. If operation is continued when the inserts are contaminated with oil, oil can leak from the air filter and result in oil contamination Checking the spark plug Check and clean the spark plug after 50 operating hours at the most. Use only the supplied Universal bolt spanner to screw the spark plug in and out. The separation between the two electrodes of the spark plug should be between 0.7 and 0.8 mm. Correct the separation if it is too large or too small. If the spark plug is affected or contaminated by carbon, clean it thoroughly or insert a new spark plug. Use only repla- cement spark plugs of the same type. (25) Lubrication Every 50 operating hours, press lubricant grease into the grease nipple (26-1). ADVICE You must comply with the prescribed lubrica- tion intervals and lubricant quantities. Otherwise, the machine may be damaged through insufficient lubrication. (26)Maintenance and care 441662_b 39 Cleaning the fuel filter (Suction head on the fuel tank) WARNING! Open flames are strictly forbidden. Check and clean the fuel filter monthly, or after 50 operating hours at the most. The fuel required by the carburettor is filtered by the fine filter (27-1) in the suction head. Carry out regular visual inspections of the fine filter. (27) In order to inspect the fine filter (27-1) , open the tank cap, and use a wire hook to pull the suction head out through the tank opening. If the fine filter (27-1) is hardened, contaminated, or blocked, then replace it (27-1) with a new filter. Replace the fine filter (27-1) at least every 3 months, so that sufficient supply of fuel to the carbu- rettor is ensured. An insufficient fuel supply results in difficulties when starting the motor, and to a reduction in the maximum rotational speed. Replacement of the fuel pipe WARNING! Open flames are strictly forbidden. Inspect and clean the fuel pipe (28-1) every day, or after 10 operating hours at the most. Replace the fuel pipe (28-1) after 200 operating hours or at least every year, regardless of the number of ope- rating hours. Otherwise, a fire may occur because of leaking fuel. If you notice leaking fuel, replace the fuel pipe (28-1) immediately. (28) Replacing the tank cap If the tank cap (28-2) is cracked or otherwise dama- ged, replace it. Over time, the tank cap shows signs of wear. Replace it every two to three years. If maintenance work and settings need to be carried out which are not explained in these instructions for use, con- tact your authorised solo by AL-KO service centre. (28)en Maintenance and care 40 163-55 / 163-70 Daily inspections and maintenance tasks Carry out the following maintenance tasks regularly, so that your machine has a long working life, and to avoid damage to the machine. Before use: Check the machine for loose bolts and missing parts. Ensure in particular that the bolts of the cutting knives are tightened correctly. Confirm that the cooling air passages and cylinder fins are not blocked. Clean these when required. Clean the fuel tank, and check for leaks and for foreign bodies in the tank. After use: Clean the hedge trimmer externally, and check it for damage. Clean the air filter. If you are working under very dusty conditions, clean the filter several times each day. Check the cutting knives for damage, and ensure that they are correctly mounted.
