• Never use the machine if the user is tired or unwell, or has taken medication, drugs, alcohol or substances that impair reexes and concentration.

• Remember that the operator or user is responsible for accidents and unexpected events that can occur to other people or property. It is the user’s responsibility to assess the potential risk of the area where work is to be carried out and to take all the necessary precautions to ensure his own safety and that of others, particularly on slopes or rough, slippery and unstable ground.

• If the machine is sold or lent to others, make sure that the operator looks over the user instructions contained in this manual.

2.2 PRELIMINARY OPERATIONS

Personal Protective Equipment (PPE)

• Always wear slim-tting protective clothes with slash-proof protection, anti-vibration gloves, helmet, protective goggles, half- mask respirator, protective earplugs, cut resistant safety boots with non–slip soles.

• Never wear scarves, shirts, necklaces, bracelets, loose owing clothing, laces or ties or any hanging or apping accessory that could catch in the machine or in any objects or materials in the work area.

• Tie your hair back if it is long. Work / Machine Area

• Thoroughly inspect the entire work area and remove anything that could be thrown by the machine or damage the cutting means/rotating units (stones, branches, iron wire, bones, etc.). Internal combustion engine: fuel DANGER! Petrol and blended fuels are highly ammable. – Keep petrol and blended fuel in approved containers, in a safe place, away from any sources of heat or naked ames. – Keep the containers out of the reach of children. – Keep the containers free of residues of grass, leaves or excessive grease – Do not smoke while blending the fuel, lling up/topping up with fuel or whenever handling the fuel. – Use a funnel to top up with fuel only in the open air. – Do not inhale fuel fumes. – Never remove the tank cap or add fuel while the engine is running or when the engine is hot. – Open the fuel tank slowly to allow the pressure inside to decrease gradually. – Do not approach the tank opening with a naked ame to check its contents. – If you have spilt some fuel, do not attempt to start the engine but move the machine away from the area of spillage and avoid creating any source of ignition until the fuel has evaporated and fuel vapours have dissipated. – Replace caps of all fuel tanks and containers securely. – Immediately clean up all traces of fuel spilt on the machine or on the ground. – Never start the machine in the same place in which you relled it with fuel; the engine must be started in an area at least 3 metres from where you refuelled. – Avoid getting any fuel or your clothing and, if this should happen, change your clothes before starting the engine.

• Do not operate the engine in conned spaces where dangerous carbon monoxide fumes can collect. The start-up operations must be carried out outdoors or in a well-ventilated area. Always remember that the exhaust gases are toxic.

• When starting up the machine, do not direct the silencer and therefore the exhaust fumes towards ammable materials.

• Do not use the machine in environments that pose the risk of explosion, in the presence of ammable liquids, gases or powders. Electrical contact orEN - 3 mechanical rubbing can generate sparks that can ignite powder or vapour.

• Work only in daylight or with good articial light in good visibility conditions.

• Keep people, children and animals away from the work area. Children must be supervised by another adult.

• Make sure that no persons are within 15 metres of the machine’s range of operation or within 30 metres for heavier cutting.

• Where possible, avoid working on wet, slippery ground or on uneven or steep ground that does not guarantee stability for the operator.

• Pay careful attention to uneven ground (hills, dips), slopes, hidden hazards and obstacles that could limit visibility.

• Be very careful near ravines, ditches or embankments.

• Always work across the face of the slope and never up and down it, being very careful when changing direction, making sure the cutting means is always down-line.

• Look out for trac when using the machine near the road. Conduct

• When working, the machine must always be held rmly in both hands, keeping the power unit on the right of the body and the cutting head below the line of the belt.

• Always use caution and take on a rm and well-balanced position.

• Never run, always walk.

• Always keep the machine connected to the harness when working.

• Always keep hands and feet away from the cutting means, when starting and when using the machine.

• Attention: the cutting means will continue to rotate for a few seconds after disengagement or after you have switched o the engine.

• Be careful of ying debris coming from the cutting means.

• Be careful of avoiding violent collisions between the cutting means and foreign objects/obstacles. Kickback may occur if the cutting means comes into contact with an obstacle/object. This contact can cause a rapid jerk in the opposite direction, pushing the cutting means up and towards the operator. Kickback can cause the operator to lose control of the machine, leading to serious consequences. To avoid kickbacks, take all the appropriate precautions indicated below: – Firmly hold the machine, with two hands, and place your body and arms in a position that allows you to resist kickback. – Do not extend the arms too high and do not cut above waist height. – Only use the cutting means specied by the manufacturer. – Follow the manufacturer's instructions concerning cutting means maintenance.

• Beware of injuries caused by devices used to cut the line length.

• Attention: The cutting element continues to rotate even after the engine has been switched o.

• Do not touch the parts of the engine that heat up during operation. Risk of burns.

• To avoid the risk of re, do not leave the machine with the engine hot on leaves or dry grass or other ammable material.

If something breaks or an accident occurs during work, turn o the engine immediately and move the machine away to prevent further damage; if an accident occurs with injuries or third parties are injured, carry out the rst aid measures most suitable for the situation immediately and contact the medical authorities for any necessary health care. Carefully remove any debris which could cause damage or injury to persons or animals if ignored.

The noise and vibration levels shown in these instructions are the maximum levels for use of the machine. The use of an unbalanced cutting element, the excessive speed of movement, or the absence of maintenance have a signicant inuence on noise emissions and vibrations. Consequently, it is necessary to take preventive steps to eliminate possible damage due to high levels of noise and stress from vibration; maintain the machine well, wear ear protection devices, and take breaks whilst working.

Prolonged exposure to vibrations can cause injuries and neurovascular disorders (also called “Raynaud’s syndrome” or “white nger”), especially to people suering from circulation disorders. The symptoms can regard the hands, wrists and ngers and are shown through loss of sensitivity, torpor, itching, pain and discolouring of or structural changes to the skin. These eects can be worsened by low ambient temperatures and/or by gripping the hand grips excessively tightly. If the symptoms occur, the length of time the machine is used must be reduced and a doctor consulted.EN - 4 Restrictions of use

• Do not use the machine if you are unable to hold it with both hands or keep steady on your legs whilst working.

• Never use the machine with damaged, missing or incorrectly positioned guards.

• Do not change the engine adjustments, or exceed the maximum rpm. If the engine is forced to run at an excessive speed, the risk of personal injury increases.

• Do not strain the machine too much and do not use a small machine for heavy- duty work; if you use the right machine, you will reduce the risk of hazards and improve the quality of your work.

2.4 MAINTENANCE, STORAGE

AND TRANSPORT Ensure regular maintenance and correct storage to maintain machine safety and high performance levels. Never use the machine with worn or damaged parts. Faulty or worn-out parts must always be replaced and never repaired. Only use original parts: using parts that are not original or installed incorrectly aects machine safety, and can therefore cause accidents or personal injury and relieve the Manufacturer of all obligations and liability. Maintenance

• To reduce the risk of re, check for oil and/or fuel leaks on a regular basis.

• Be careful during adjustment of the machine to prevent entrapment of the ngers between moving parts of the cutting means and xed parts of the machine. Storage

• Do not store the machine with fuel in the tank in an area where fuel vapours could reach a naked ame, spark or strong source of heat.

• To reduce re risks, do not leave containers with debris inside a room.

2.5 ENVIRONMENTAL PROTECTION

Protecting the environment must be a signicant and top priority for machine use, to the benet of civil co-habitation and of the environment that we live in.

• Avoid being an element of disturbance to the surrounding area. Use this machine at reasonable times of the day only (not early morning or late evening when the noise could cause disturbance).

• Adhere strictly to the local regulations governing the disposal of packaging, oil, fuel, lters, damaged parts or any other element which may have an impact on the environment; this waste must not be disposed of with regular waste, but must be separated and taken to collection centres, which will recycle the materials.

• Comply with local regulations for the disposal of waste materials.

• When the machine is withdrawn from service, do not dispose of it in the environment, but take it to a waste disposal facility in accordance with the local regulations in force.

Do not use the machine for sweeping, tilting the cutting line head. The engine is powerful enough to throw objects and small stones 15 metres or more, causing damage to objects and injury to people; a. Cutting motion (Scything) Proceed at a regular pace, with a circular motion similar to a traditional scythe, without tilting the cutting line head during the operation (Fig. 17). First try cutting at the right height in a small area, so as to then achieve a uniform cutting height keeping the cutting line head at a constant distance from the ground. For heavier cutting it can be useful to tilt the cutting line head to the left by about 30°. Do not work in this way if there is the possibility of causing objects to be thrown, which could harm people, animals or cause damage. b. Precision cutting (Trimming) Keep the machine slightly tilted so that the lower part of the cutting line head does not touch the ground and the cutting line is at the required point, always keeping the cutting means at a distance from the operator. c. Cutting near fences/foundations Move the cutting line head slowly towards fences, posts, rocks, walls, etc. without hitting them hard (Fig. 18). If the line strikes a solid object it could break or become worn; if it gets tangled in a fence it could break suddenly. In any case, cutting around pavements, foundations, walls, etc. can cause greater wear than normal to the line. d. Cutting around trees Walk round the tree from left to right, approaching the trunks slowly so as not to strike the tree with the line and keeping the cutting line head tilted forward slightly (Fig. 19). Remember that the nylon line could lop o or damage small shrubs and that the impact of the nylon line against the trunk of bushes or trees with soft bark could seriously damage the plant.

6.4.1.b 3 point, 4 point and 8 point blades:

Start cutting from above the vegetation and then descend with the mowing blade to cut branches by chopping them into small pieces (Fig. 20).

6.4.1.c Saw blade (if allowed):

Where permitted, the saw blade must be used with the specic guard always tted (section 4.4.2). The blade should always be well sharpened to reduce the risk of kickbacks. When felling small trees, assess the direction of fall of the tree when cut, taking wind direction also into consideration. To obtain good results when felling small trees, make the cut with rapid movements towards the branch or trunk to be cut with the engine at maximum rpm. Avoid using the right side of the blade since their is a high risk of kickback or jamming the blade in view of the direction of rotation (Fig. 21).

6.4.2 Adjusting the length of the

cutting line head during work This machine is tted with a semi- automatic wire release head.EN - 13 Head line length should be adjusted: – when the line is consumed and becomes shorter; – when engine rotation seems higher than normal; – when cutting eciency seems reduced. To release new line:

• hit the cutting line head against the ground (Fig. 21) with the throttle control lever pressed fully down;

• the wire is automatically released and the wire cutting knife (Fig. 27.A) cuts the excess length.

6.5 ADVICE FOR OPERATION

During use, it is advisable to remove cut vegetation wrapped around the machine at regular intervals to avoid engine overheating (Fig. 1.A) caused by grass trapped under the cutting means guard (Fig. 1.E.1, Fig. 1.E.2). Proceed as follows: – stop the machine (par. 6.6); – take the cap o the spark plug (Fig. 14.H) – wear protective gloves; – remove the caught-up grass with a screwdriver to allow the engine to be properly cooled. NOTE During the rst 6-8 hours of machine operation, avoid using it at maximum speed.

• Release the throttle lever briey (Fig. 14.B) and allow the engine to idle for a few seconds.

• turn the switch (Fig.14.A) to position "O";

• Wait until the cutting means stops. When you set the throttle to idle, it will take a few seconds for the cutting means to stop. IMPORTANT Always stop the machine when moving between work areas. The engine may be very warm immediately after it is shut o. Do not touch. This can cause burn injuries.

• When the cutting means has halted, t the blade guard;

• Allow the engine to cool before storing in an enclosed space.

• Make sure there are no loose or damaged components. If necessary, replace damaged components and tighten any slack screws and bolts. IMPORTANT Stop the machine (section .6.6), remove the spark plug cap (Fig.14.H) and t the blade guard whenever the machine is left unattended.

IMPORTANT The safety regulations to follow are described in chap. 2. Strictly comply with these instructions to avoid serious risks or dangers. Before performing any maintenance operations:

• when the cutting means is stationary, apply the blade protection cover, (except when working directly on the blade);

• allow the engine to cool before storing in an enclosed space;

• use suitable clothing, protective gloves and goggles;

• read the relevant instructions;

• The frequency and types of maintenance are summarised in the "Maintenance Table" (see

chapter 13). The table will help you maintain

your machine’s safety and performance. It summarises the main interventions to be made and the frequency applicable to each of them. Carry out the relevant task as soon as it is scheduled to be performed.

• The use of non-original parts and accessories could have negative eects on machine operation and safety. The manufacturer declines any responsibility for damage or injury caused by said products.

7.2 PREPARING THE FUEL BLEND

This machine is equipped with a 2-stroke engine that requires a blend of petrol and lubricating oil. IMPORTANT Using petrol alone damages the engine and will void the warranty. IMPORTANT Use only high quality fuels and lubricants to maintain performance and ensure the durability of mechanical parts.

7.2.1 Petrol - characteristics

Use only unleaded petrol (green petrol) with an octane of no less than 90 N.O. IMPORTANT Green petrol tends to create deposits in the container if stored for more than 2 months. Always use fresh petrol!

7.2.2 Oil - characteristics

Use only high quality synthetic oil specic for 2-stroke engines. Your Dealer will have oils specially designed for this type of engine which can guarantee a high level of protection. Using these oils allows a 2.5% blend to be used, comprising 1 part oil for every 40 parts petrol.

7.2.3 Preparing and storing the fuel blend

Preparing the fuel blend

1. add approximately half of the amount

of petrol to a type-approved canister;

4. close the cap and shake vigorously.

IMPORTANT The fuel blend is subject to ageing. Do not prepare excessive quantities of fuel blend to prevent the formation of deposits. IMPORTANT Keep containers of fuel blend and petrol separate and clearly identied to avoid swapping them at the time of use. IMPORTANT Clean the petrol and fuel blend containers at regular intervals to remove any deposits.

1. vigorously shake the canister

containing the fuel blend;

2. place the machine on a level surface

in a stable position with the fuel tank cap facing upwards (Fig. 14.G). NOTE The fuel tank (Fig. 14.G) has the following symbol: Fuel blend tank.

3. Clean the fuel cap and the surrounding area

to avoid ingress of dirt when refuelling.

4. Carefully open the fuel tank slowly to allow

the pressure to decrease gradually.

5. Refuel using a funnel; do not ll

the tank right to the top.

7.4 CLEANING THE MACHINE

Always clean the machine after use. To reduce the risk of re: – keep the machine and especially the engine free from residues of grass, leaves or excessive grease; – frequently clean the cylinder ns with compressed air and eliminate sawdust, twigs, leaves or other debris from the silencer area. To avoid overheating and damage to the engine, always keep the cooling air vents clean and free of sawdust or debris.EN - 15

• Keep all nuts, bolts and screws tight to be sure the equipment is in safe working condition.

• Check regularly that the handles are xed rmly.

LUBRICATION: Lubricate with lithium based grease. Remove the screw (Fig. 23.A) and insert the grease by rotating the shaft by hand until the grease comes out; then ret the screw (Fig. 23.A).

8.2 FLEXIBLE DRIVE-SHAFT

LUBRICATION Lubricate with lithium-based grease.

1. Unhook the tube (Fig. 23.B)

from the engine side;

2. extract the exible drive-shaft (Fig. 23.C);

3. apply grease rotating the drive-

shaft manually until the grease is distributed over the entire surface; then reassemble (par. 4.6).

8.3 CLEANING THE AIR FILTER

IMPORTANT Cleaning the air lter is essential for correct operation and durability of the machine. NEVER work without a lter or with a damaged lter to avoid causing irreparable damage to the engine. Cleaning must be performed every 15 hours of work. To clean the lter:

2. blow compressed air from the inside

and the cover (Fig. 24.A); then tighten the screws (Fig.24.B);

Remove and clean the spark plug at regular intervals; remove any deposits with a wire brush (Fig. 26). Check and reset the correct gap between the electrodes (Fig. 26). Ret the spark plug and tighten it fully using the wrench supplied. The spark plug must be replaced with one having similar characteristics if burnt electrodes or deteriorated insulation are found or after every 100 hours of operation.

8.5 CUTTING MEANS MAINTENANCE

When servicing the cutting means, bear in mind that it can still move even if the spark plug cable been disconnected. Cutting means displaying the code indicated on the Technical Data table should only be used on this machine. Given product evolution, the cutting means mentioned in the "Technical Data" table may be replaced in time with others having similar interchangeable and operating safety features. Do not touch the cutting means until the spark plug cable has been disconnected and the cutting means is completely stationary. Wear protective gloves.

8.5.1 Blade sharpening/balancing

For safety reasons, sharpening and balancing should be performed by an Authorised Service Centre with suitable skills and equipment for the job; without risking any damage to the blade which would make it unsafe when used. 3 point, 4 point and 8 point blades can be used on both sides. When one side of the points is worn, the blade can be turned and the other side used. When both sides of the points are worn, have them sharpened. The saw blade is not reversible and therefore should only be used on one side.

8.5.2 Blade replacement

The blade must never be repaired, but must be replaced as soon asEN - 16 signs of breaking are noted or the sharpening limit is exceeded. For replacement procedures, see sections 4.5.3 and 4.5.4.

8.5.3 Replacing the cutting line head

• Type I Follow the sequence shown in (Fig. 28).

• Type II Cut the new line to the indicated length (Fig. 29.A).

5. Insert one end of the line (Fig. 30.D) in

one of the two output holes and pass the line through the opposite hole.

6. Align the lines that exit the

following the direction of the arrows to wind the line, being careful to leave about 175 mm from both holes (Fig. 31.B). If old line is left in the head or if broken inside it, remove as described below:

1. press the tabs on the sides of the

cutting line head, where marked “PUSH” (Fig. 32.A), and detach the lower part of the head (Fig. 32.B);

2. Remove the line left inside;

3. replace the reel (Fig. 33.A) in its housing;

4. close the head by fastening the tabs (Fig.
