• Never allow children or persons unfamiliar with these instructions to use the machine. Local regulations may restrict the age of the operator.

• Never use the machine if the user is tired or unwell, or has taken medicine, drugs, alcohol or any substances which may slow their reexes and compromise their judgement.

• Bear in mind that the operator or user is responsible for accidents or unexpected events occurring to other people or their 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.

• It takes specic training to use the machine for felling and delimbing.

Personal Protective Equipment (PPE)

• Always wear slim tting protective clothing 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, clothing with owing parts, 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. Internal combustion engines: fuel DANGER! Petrol and the fuel mixture are highly ammable!

• Keep the petrol and fuel mixture in approved fuel containers, in a safe place, away from any naked lights or heat sources.

• Keep the fuel containers and storage area free of sawdust, branches, leaves, or excessive grease.

• Keep the containers out of the reach of children.

• Do not smoke when preparing the mixture, when lling or topping up with fuel or when 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 whilst 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.

• Immediately clean up all traces of fuel spilt on the machine or on the ground.

• Replace caps of all fuel tanks and containers securely.

• 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.

• If fuel is spilt on clothing, change clothing before starting the engine.

• Do not operate the engine in a conned space where dangerous carbon monoxide fumes can develop. All starting operations must be carried out in an open or well ventilated area! Always remember that exhaust fumes 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 at risk of explosion, in the presence of ammable liquids, gas or powder. Electrical contacts and mechanical friction can generate sparks that can ignite the powder or vapours.

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

• Keep persons, children and animals away from the working area. Ask another adult to keep the children under supervision.

• Check that there is anybody within at least 15 metres of the machine's range of action.

• Where possible, avoid working on wet, slippery ground or in any case on uneven or steep ground that does not guarantee stability for the operator;EN - 3

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

• Be very careful near ravines, ditches or embankments.

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

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

• When running, the machine must always be rmly held in both hands, (left hand on the front hand grip and the right hand on the rear hand grip, even if the operator is left-handed) at a safe distance from all body parts.

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

• Avoid using unstable ladders or platforms.

• Avoid working alone or in an isolated place, in case you have to nd help after an accident.

• Never run, always walk.

• Make sure the bar does not come into violent contact with foreign bodies/obstacles and try to prevent any material from being hurled by the moving chain. Kickback may occur if the bar comes into contact with an obstacle. Kickback occurs when the tip of the chain comes in contact with an object or when the wood contracts and jams the chain during sawing. This contact with the tip of the chain can cause a rapid backward motion, pushing the guide bar up and towards the operator. This also happens when the chain is jammed along the upper part of the bar. In both cases, kickback can cause the operator to lose control of the chainsaw, leading to serious consequences. To prevent kickbacks, take all appropriate precautions provided below: – Hold the saw rmly, with the thumbs and ngers around the chainsaw grips, and position your body and arms so that you can resist the force of a kickback. – Do not fully extend the arms and do not saw above shoulder height. – Only used the guide bar and chains recommended by the manufacturer. – Follow the manufacturer's instructions regarding sharpening and maintenance of the chainsaw.

• Avoid exposure to dust and sawdust produced by the chain when cutting.

• Do not touch the engine parts which heat up during use. Burns hazard.

• 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.

• Prolonged exposure to vibrations can cause injuries and neurovascular disorders (also called "Raynaud’s syndrome" or "white hand"), especially to people suering from circulation disorders. The symptoms appear in 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. Use limitations

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

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

• Don’t use the machine if the attachments/ tools are not installed in their seats.

• Never disengage, deactivate, remove or tamper with the safety systems/ microswitches installed.

• Do not alter the engine adjustments, nor over-run it. If the engine is forced to work with an excessive number of rotations, 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

Ensure regular maintenance and correct storage to maintain machine safety and high performance levels. Maintenance

• To reduce the risk of re, regularly check the machine for oil and/or fuel leaks.

• 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 noiseEN - 4 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. Storage

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

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

2.5 ENVIRONMENTAL PROTECTION

Safeguarding the environment must be a relevant and priority aspect of machine use, of benet to the community and the environment we live in.

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

• A certain amount of chain lubricating oil is released into the environment when the machine is running, so only use biodegradable oils made specically for this use. Use of a mineral oil or engine oil causes serious damage to the environment.

• 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 should not be disposed of along with standard household waste, but must be disposed of separately and sent to special waste disposal facilities for handling and recycling.

• 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.

This machine is a forestry tool and precisely a chainsaw designed for forestry work. The machine is essentially composed of a 2-stroke internal combustion engine, fuelled by an air-cooled oil-petrol mix, and a guide bar that drives the power from the engine to the toothed chain that acts as a fully edged saw. The movement is transmitted from the engine to the chain by a centrifugal clutch that prevents the chain from moving when the engine is running at minimum speed. The operator is able to operate the machine with two hands, using the front and rear hand grips, and use the main controls, always remaining at a safe distance from the cutting means.

This machine was designed and manufactured for: – felling, bucking and delimbing trees with dimensions suitable for the length of the guide bar or wooden objects with the same characteristics; – use by one operator.

Any other usage not in keeping with the above- mentioned ones may be hazardous and harm persons and/or damage things. Examples of improper use may include, but are not limited to: – trimming hedges; – carving operations; – sectioning pallets, crates and various packing materials; – sectioning furniture or other materials with nails, screws or other metal components; – butchering meat; – using the machine to cut materials other than wood (plastic materials, building materials); – using the machine to lift, move or split objects; – using the machine while fastened to xed supports; – using cutting means other than those found in the "Technical Data" table. Serious injury and wound hazard. – use of the machine by more than one person. IMPORTANT Improper use of the machine will invalidate the warranty, relieve the Manufacturer from all liability, and the user will consequently be liable for all and any damage or injury to himself or others.EN - 5

This machine is intended for use by consumers, i.e. non-professional operators. The machine is intended for "DIY" use only.

The machine has various symbols on it (Fig. 2). They are used to remind the operator of the behaviour to follow to use it with the necessary attention and caution. Meaning of symbols: WARNING! DANGER! Failure to use this machine correctly can be hazardous for oneself and others WARNING! Read the instruction manual before using the machine. Anyone operating the machine under normal conditions for continuous daily use may be exposed to a noise level equal to or exceeding 85 dB (A). Wear ear protectors, safety goggles and a protective helmet. Wear gloves and safety boots! BEWARE OF KICKBACK! Kickback is the rapid and uncontrollable backward motion of the chainsaw in the direction of the operator. Always work in complete safety. Use chains with safety links that limit kickback. Never hold the machine with one hand! Hold the machine fast with both hands to control the machine and reduce the risk of kickback. IMPORTANT Any damaged or illegible decals must be replaced.

6.1.4 Preparing the machine

before starting work

• Anti-freeze device When using the chainsaw at temperatures under +5°C, it is necessary to change the anti-freeze de- vice settings before starting the machine to prevent ice from forming inside the carburettor, which will result in a loss in engine power or erratic engine performance. The machine is equipped with an air vent hatch on the cylinder lid, to allow warm air ow to the engine. In normal operating conditions (temperatures above +5°C), use the machine in standard operat- ing mode, i.e. using factory default settings. To switch from "Normal " mode to "Anti-freeze " mode (and vice versa):

1. stop the machine (par. 6.6);

2. remove the air lter cover and

3.a on models SP386, SP 426: – remove the anti-freeze cap from its housing to the right of the cylinder cover (Fig. 14.A); – Turn the anti-freeze cap so that the «SNOW» symbol is facing downwards to leave the air vent hatch open (Fig. 14.B); 3.b on models SP466, SP 526: – unscrew the screws which secure the cylinder cover in place (Fig. 15.A) (2 screws inside and one outside) and remove the cylinder cover. (Fig. 15.B); – remove the anti-freeze cap from its housing (Fig. 16.A), in the centre and at the back of the cylinder cover (Fig. 16.B); – Turn the anti-freeze cap so that the «SNOW» symbol is facing downwards (Fig. 17.A) to leave the air vent hatch open (Fig. 17.B); – remount the cylinder cover.

4. remount the air lter cover and

the relative cover (par. 8.2). NOTE If the machine is used in anti-freeze mode at temperatures above +5°C, this may cause diculties when starting the engine and during use due to the incorrect engine speed. Always check that the machine is switched to standard mode (anti-freeze cap with the «SUN» symbol facing sideways and the air vent hatch closed) if there is no danger of ice forming.EN - 9

Press the pressure relief valve (Fig. 13.E). NOTE Immediately after the engine starting, the valve automatically returns to its original position.

3. Engage the choke (position «B» - par.

5.2) and then immediately disengage again (position «A» - par. 5.2); this will engage the fast tick over.

4. Follow points 4 - 7 - 8 - 9 in the

Before felling or delimbing for the rst time, make sure: – you have been specically trained to use this type of equipment; – you have carefully read the safety regulations and user instructions contained in this manual; – you practise rst on logs on the ground or attached to trestles, in order to get familiar with the machine and the most suitable cutting techniques. To operate with the machine proceed as described below:EN - 11

• Always disengage the chain brake, before using the throttle control.

• The machine must always be rmly held in both hands, with the left hand on the front hand grip and the right hand on the rear hand grip, even if the operator is left handed. Stop the machine immediately if the chain stops during sawing.

6.4.1 Checks to be conducted

The chain tends to stretch gradually as you work, so you need to check its tension frequently (par. 6.1.3).

6.4.1.b Checking the oil delivery

IMPORTANT Never use the machine without lubrication! The oil tank may also be empty every time the fuel runs out. Make sure you top up the oil tank every time you refuel the machine (par. 7.4). Make sure the bar and the chain are in place when you check the oil delivery. Start the engine (par. 6.3), keep it running at medium power and check if the chain oil is delivered as shown in (Fig. 19). You can adjust the chain oil ow using a screwdriver on the pump adjuster screw (Fig. 20.A) which is on the bottom of the machine. This is the symbol that identies the oil pump regulator:

Use a screwdriver to turn it to the "+" position to increase the oil ow to the chain; turn it to the "-" position to decrease the ow.

Make sure there is nothing or anybody in the area where the branches will fall.

1. Stand opposite the branch you want to cut.

2. Start cutting lower branches

followed by the higher ones.

3. Cut downwards to prevent the bar

from getting jammed (Fig. 21).

6.4.2.b Felling a tree

IMPORTANT Where two or more persons are working together on felling and bucking operations, such operations must be performed in separate areas at a distance from each other of at least 2.5 times the height of the tree being felled. Do not fell trees if this involves risks of injuring people, coming into contact with a power line or causing any form of damage. If the tree should come into contact with a main power line, report the incident immediately to the network provider. Before commencing the felling operations: – it is necessary to evaluate the natural inclination of the tree, the part where the branches are larger and the wind direction, to assess how the tree will actually fall; – remove any dirt, stones, pieces of bark, nails, metal staples and wire; – clear the area around the tree and nd a stable place to stand; – plan obstacle-free escape routes at a 45° angle back and away from the direction of the fall (Fig. 22) which allow the operator to escape to a safe zone, approximately2.5 times the height of the tree being felled; – Stand upstream of the land onto which the tree will probably roll or fall over after felling.

• Performing a face notch

1. Following the directional marks on the

chainsaw (Fig. 23.A), point towards a target on the ground in the direction in which you intend to fell the tree (Fig. 23.B).

2. Stand to the right of the tree,

behind the chainsaw.

3. Saw a horizontal face notch to 1/3 of the

diameter of the tree, perpendicular to the direction in which it will fall (Fig. 24.A).

4. Perform the felling back cut at least

5 cm higher than the horizontal face notch (Fig. 24.B).

5. Perform the felling back cut leaving

sucient wood to act as a "hinge" (Fig. 24.C). The hinge wood will prevent the tree from twisting and falling in the wrong direction. Do not cut through the hinge.EN - 12

6. Reduce the thickness of this hinge without

pulling out the bar, until the tree falls.

7. If there is any risk of the tree not falling

in the desired direction, or that it might lose its balance moving backwards and bending the toothed chain, stop cutting before completing the felling back cut and use some wooden, plastic or aluminium wedges (Fig. 24.D) to open the cut. Force the tree to fall along the desired line by hitting the wedges with a sledge hammer.

8. When the tree starts to fall, it is necessary to

withdraw the machine from the cut, switch it o (par. 6.6), lie it on the ground and take the foreseen exit route. Beware of falling branches and pay attention where you put your feet.

6.4.2.c Limbing tree branches

Limbing means removing the branches from a felled tree. Be careful of where the branches are lying on the ground, the risk of them being under tension, the direction the branch may go during cutting and the risk of the tree being unstable after the branch has been cut. When limbing, it is necessary to leave the lower, larger branches to support the trunk on the ground. Remove the small branches with a single blow (Fig. 25.A). It is recommended to cut the tensioned branches working from the bottom upwards to prevent the chainsaw from bending (Fig. 25.B).

6.4.2.d Bucking the trunk

Bucking means sawing a tree trunk into logs. It is essential to make sure your feet are positioned rmly on the ground, and your weight is distributed equally on both feet. If possible, it is recommended to raise and support the trunk using branches, logs or blocks of wood. It is easier to saw a log using the spiked bumper (Fig. 1.I):

1. plant the spiked bumper into the log and use

it as a pivot. Cut with an arched motion to make the bar penetrate the wood (Fig. 26);

2. repeat several times if necessary, changing

the point where you plant the spiked bumper.

• Trunk lying on the ground When the entire trunk is lying on the ground, it is bucked from the top down (overbucking) (Fig. 27.A). – Cut up to half the diameter, roll the log over and nish sawing on the other side.

• Trunk resting on one end only When the trunk is resting on one end only: – saw through 1/3 of the diameter from the bottom up (underbucking) (Fig. 28.A); – then perform the nal cut, overbucking to reach the rst cut (Fig. 28.B).

• Trunk resting on both ends When the trunk is resting on both ends: – saw through 1/3 of the diameter from the top down (overbucking) (Fig. 29.A); – then perform the nal cut, underbucking the lower 2/3 to reach the rst cut (Fig. 29.B).

• Sloping trunk Always stand upstream when bucking a sloping trunk (Fig. 30). During the operation, to maintain control when the cut is almost complete, reduce the bucking pressure without removing removing your hands from the machine hand grips. Take all necessary precautions to prevent the machine from coming into contact with the ground.

6.5 ADVICE FOR OPERATION

NOTE Avoid using the machine at full power for the rst 6- 8 working hours. IMPORTANT Stop the machine (par. 6.6) when moving between work areas.

1. Release the throttle trigger lever (Fig.

12.B) and allow the engine to run at idle speed for a few seconds.

3. Wait until the chain is stationary.

When you have reduced speed to a minimum, it will take a few seconds for the chain to stop. The engine may be very warm immediately after it is shut o. Do not touch. The engine can cause burn injuries.EN - 13

– Remove the spark plug cap (Fig. 31.A). – Mount the bar cover. – Allow the machine to cool down. – Loosen the rod fastening nuts to reduce chain tension. – Carefully remove any dust and debris and remove all traces of sawdust or oil deposits from the chain. (par. 7.5, par. 7.6). – Check there are no loose or damaged components. If necessary, replace the damaged components and tighten any screws and loose bolts. IMPORTANT Stop the machine (par. 6.6), remove the spark plug cap (Fig. 31.A) and mount the bar cover whenever the machine is unused or left unattended.

IMPORTANT The safety regulations to follow during machine use are described in Chapter 2. Strictly comply with these instructions to avoid serious risks or hazards. Before conducting any inspections, cleaning or maintenance/ adjustment interventions on the machine:

• Wait until the chain is stationary;

• Apply the bar cover, except when working directly on the chain or bar itself.

• Remove the spark plug cap (Fig. 31.A);

• Wait until the engine is suciently cold;

• Read the relevant instructions;

• Use suitable clothing, protective gloves and goggles;

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

chapter 12). 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 intervention according to the rst deadline.

• The use of non-genuine spare parts and attachments could adversely aect machine operation and safety. The manufacturer shall decline all liability in the event of injuries or damages caused by such parts.

• Genuine spare parts are supplied by Authorized Service Centres and Dealers.

• Never use the machine with worn or damaged parts. Damaged parts are to be replaced and never repaired. IMPORTANT All the maintenance and adjustment operations not described herein must be carried out by your dealer or Authorised Service Centre.

7.2 PREPARING THE FUEL MIXTURE

This machine has a two-stroke engine which requires a mixture of petrol and lubricating oil. IMPORTANT Using petrol alone will damage the engine and will void the warranty. IMPORTANT Only use quality fuels and oils to maintain high performance and guarantee the duration of the mechanical parts over time.

7.2.1 Petrol characteristics

Only use unleaded petrol with an octane rating of at least 90. IMPORTANT Unleaded petrol tends to create deposits in the container if stored for more than 2 months. Always use fresh petrol!

7.2.2 Oil characteristics

Only use top quality synthetic oil that is specically for two-stroke engines, of JASO FC minimum specication. Your dealer can provide you with oils which have been specically developed for this type of engine, and which are capable of guaranteeing a high level of protection. The use of these oils makes it possible to prepare a 2.5% mixture, consisting of 1 part oil to 40 parts petrol.

7.2.3 Preparation and storage

of the fuel mixture The chart indicates the amount of petrol and oil to use to prepare the fuel mixture. Petrol 2-stroke synthetic oil litres litres

To prepare the fuel mixture:

1. Place about half the amount of

petrol in a homologated tank.

3. Add the rest of the petrol.

4. Close the top and shake well.

IMPORTANT The fuel mixture tends to age. Do not prepare excessive amounts of the fuel mixture to avoid the formation of deposits. IMPORTANT Keep the petrol and fuel mixture containers separate and easily identiable to avoid the mistake of using one in place of the other. IMPORTANT Periodically clean the petrol and fuel mixture containers to remove any deposits.

Refuelling must take place when the machine is switched o and the spark plug cap removed. Before refuelling:

1. Shake the fuel mixture container well.

2. Place the machine on a at stable surface,

with the fuel tank cap facing upwards. NOTE The following symbol is found near the fuel tank cap (Fig.32.A): Fuel mixture tank

3. Clean the fuel tank cap and the

surrounding area to prevent any dirt from entering the tank during refuelling.

4. Open the fuel tank cap carefully to allow

the pressure inside to decrease gradually.

5. Use a funnel to rell and avoid

lling the tank to the brim. NOTE When using the machine, the fuel level can be checked through the tank window (Fig. 32.B).

7.4 TOPPING UP THE CHAIN OIL TANK

NOTE The following symbol is found near the chain oil tank cap (Fig. 32.C): Chain oil tank IMPORTANT Only use chainsaw oil or adhesive oil for chainsaws. Do not use oil containing impurities so as not to block the oil lter and to prevent irreparable damage to the oil pump. It is essential that you use good quality oil to lubricate the cutting parts eectively. Used or poor quality oil does not guarantee good lubrication and reduces the working life of the chain and bar. – It is always worth topping up the oil tank completely (using a funnel) every time you refuel. Since the oil tank capacity is enough to guarantee that the fuel runs out rst, you will avoid the risk of operating the machine without lubricant.

7.5 CLEANING THE MACHINE

After every work session, clean the machine thoroughly to remove all dust and debris.

• To reduce re hazards: – keep the machine and, in particular, the engine and muer zone free of sawdust, branches, leaves, or excessive grease; – use compressed air to clean the cylinder ns on a regular basis (Fig. 33).

• To avoid overheating and damage to the engine: – always keep the cooling air vent (Fig. 34) clean and free of sawdust and debris.

• Keep the clutch bell free of sawdust and debris (Fig. 35), removing the clutch (par. 4.2) and remounting it correctly afterwards. Have your dealer check the greasing of the internal bearing approximately every 30 hours.

7.6 CLEANING THE CHAIN

Remove any traces of sawdust or oil deposits from the chain every time it is used. If there is excessive dirt or resin build-up, disassemble the chain and place it in a container with a specic cleanser for a fewEN - 15 hours. Then rinse with clean water and treat with a suitable anticorrosive spray, before reassembling on the machine.

Before use, always check the condition of the chain catcher (Fig.1.H) beforehand and replace it if damaged.

• Before use, always check that all nuts and bolts are securely tightened to be sure the machine is in safe working condition.

• Before use, always check that the hand grips are rmly fastened in place.

IMPORTANT Cleaning the air lter is essential to guarantee the eciency and durability of the machine. Do not work with a damaged lter or without a lter, as this could permanently damage the engine. It must be cleaned after every 8-10 working hours. Clean the lter as follows:

2. Press the metal air lter block until it

attaches with a click (Fig. 38.A).

3. Remove the air lter (Fig. 38.B),

tap it gently to remove the dirt and clean using a soft brush.

4. If the lter is completely clogged, wash with

clean petrol. If you are using compressed air, aim the jet so that it blows from the inside towards the outside (Fig. 39.A).

5. Replace the lter (Fig. 40.B), pull

the metal block (Fig. 40.A) until it clicks the lter into position.

6. Remount the casing (Fig. 41.A)

making sure that all the parts are positioned correctly in their housings on the cylinder cover (Fig. 41.B).

7. Insert the lower section of the

tab and press the top part until it clicks into place (Fig. 41.C).

Have your dealer check the condition of the metal band around the clutch housing once a month. The band must be replaced if deteriorated or deformed.

8.4 CHAIN DRIVE SPROCKET

Regularly check the condition of the sprocket with your local dealer or Authorised Service Centre and replace it when wear exceeds the accepted limits. Do not mount a new chain with a worn sprocket or vice-versa.

8.5 CHECKING THE SPARK PLUG

The spark plug (Fig. 31.A) can be accessed by removing the air lter cover (Fig. 37.B). Periodically remove and clean the spark plug using a metal brush to get rid of any deposits (Fig. 42.A). Check and reset the correct distance between the electrodes (Fig. 42.B). Replace the spark plug and fasten it rmly using the supplied wrench. The spark plug must be replaced with one with the same characteristics whenever the electrodes have burnt or the insulation has worn, and in any case every 100 working hours.

The starter rope must be replaced by your Dealer or Authorised Service Centre as soon as it shows signs of wear.

8.7 MAINTENANCE OF THE

TOOTHED CHAIN To ensure that the chainsaw works safely and eciently, it is essential that the cutting means are well-sharpened. Chain sharpening is necessary when: – the sawdust looks like dust. – cutting becomes more dicult.EN - 16 – the cut is not straight. – vibrations increase. – fuel consumption increases. Kickback may occur if the chain is not suciently sharpened IMPORTANT It is recommended to have a specialised centre sharpen the chain using the right tools to ensure minimum removal of material and even sharpness on all the cutting edges.

8.7.1 Chain sharpening

If you sharpen the chain yourself, use special round-section les with the right diameter depending on the type of chain (see "Chain Maintenance Table ", chap. 14). You need a certain amount of skill and experience to avoid damaging the cutting edges. Sharpen the chain as follows:

3. Secure the bar with the chain in a vice (Fig.

43.A), so that the chain can run smoothly.

4. Tighten the chain if it is loose (par. 6.1.3).

5. Insert the le in the tooth at a constant

angle from the cutting edge (Fig. 43.B). Using a sharpening plate makes using the le easier (Fig. 43.C).

6. Sharpen in a forward motion a few times

and repeat this on all the cutting edges facing the same way (right or left).

7. Turn the bar over in the vice and repeat

on all the other cutting edges.

8. Check that the limiter tooth (Fig. 43.D)

complies with the levels indicated in the "Chain Maintenance Table" (chap.

14) and le any projecting parts with

a at le, rounding o the edge.

9. After sharpening, remove all traces of ling

and dust and lubricate the chain in an oil bath.

8.7.2 Replacing the toothed chain

Replace the chain when: – the length of the cutting edges reduces to 5 mm or less (Fig. 43.E); – there is too much play between the links and the rivets. – the cutting speed is too slow and the repeated sharpening does not improve the cutting speed. The chain is worn. IMPORTANT After replacing the chain, its tension level must be checked more frequently due to settling of the chain.

8.8 GUIDE BAR MAINTENANCE

NOTE Any work on the guide bar requires specic experience and special tools in order to achieve top workmanship standards; for safety purposes, we recommend you contact your dealer to ensure work is done correctly. To avoid asymmetrical wear on the bar, make sure it is turned over periodically. To keep the bar in perfect working order, proceed as follows:

1. Grease the bearings on the nose sprocket

(if present) with the syringe (not included).

2. Clean the bar groove with the scraper

(not included) (Fig. 44.A);

3. Clean the lubrication holes (Fig. 44.B);

4. With a at le (not included), remove burr

from the edges and level o the guides.

8.8.1 Replacing the bar

Replace the bar whenever: – the groove is not as deep as the height of the drive links (which must never touch the bottom); – the inside of the guide is worn enough to make the chain lean to one side.

8.9 TUNING MINIMUM SPEED

If the cutting means moves when the engine is running idle, contact your dealer or Authorised Service Centre to have the engine adjusted correctly (par. 8.11).

8.10 TUNING THE CARBURETTOR

The carburettor is tuned by the manufacturer to achieve maximum performance in all situations, with a minimum emission of toxic gas in compliance with the regulations in force. In the event of poor performance, contact your Dealer or Authorised Service Centre for a check of the carburetion and engine. Carburettor tuning: T = minimum speed tuning L = low speed mixture tuning H = high speed mixture tuningEN - 17

9. STORING THE MACHINE

IMPORTANT The safety regulations to follow for putting into storage are described in paragraph 2.4. Strictly comply with these instructions to avoid serious risks or hazards. If you are not going to use the machine for a period of more than 2-3 months, we recommend you do a few things before putting it away. This will make it easier when you want to use the machine again and will also prevent permanent damage to the engine. Before putting the machine away:

1. Unscrew the two clutch housing nuts, remove

the housing and remove the chain and bar.

2. Empty the oil tank, ll with about 100-120 cc

of specic liquid detergent and plug the cap.

3. Fit the guard back on without

tightening the nuts.

4. Start the engine and keep it running

until all detergent is used.

5. Start the engine and run it idle until

it uses up all the fuel that is left in the tank and the carburettor.

6. Wait for the engine to cool.

7. Remove the spark plug.

8. Pour a teaspoon of (new) 2-stroke

engine oil into the spark plug slot.

9. Pull the starter hand grip several

times to deliver oil to the cylinder.

10. Replace the spark plug with the

piston in the dead end upper position (visible from the spark plug slot when the piston is at maximum stroke).

11. Clean the machine thoroughly.

– in a dry place – protected from inclement weather – with the bar cover guard tted correctly – in a place where children cannot get to it – making sure that keys or tools used for maintenance are removed. Before starting to use the machine again:

1. Remove the spark plug.

2. Pull the starter hand grip a few

times to eliminate excess oil.

When handling or transporting the machine, always: – stop the machine (par. 6.6). – wait until the chain is stationary. – remove the spark plug cap (Fig. 31.A). – mount the bar cover. – only hold the machine using the hand grips and position the bar in the opposite direction to that used during operation. When transporting the machine on a vehicle, always: – position it so that it does not cause a hazard to anyone; – fasten rmly to the means of transport using ropes or chains to prevent it from tipping over causing damage and fuel leaks.
