GENERAL SAFETY PRECAUTIONS English – 11 1155296-38 Rev.1 2012-11-19If you get a violent kickback while the kickback zone of the bar is farthest away from you the chain brake is designed to be activated by the inertia in the kickback direction. (8) If the kickback is less violent or the kickback zone of the bar is closer to you the chain brake will be activated manually by the movement of your left hand. • In the felling position the left hand is in a position that makes manual activation of the chain brake impossible. With this type of grip, that is when the left hand is placed so that it cannot affect the movement of the front hand guard, the chain brake can only be activated by the inertia action. (9) Will my hand always activate the chain brake during a kickback? No. It takes a certain force to move the hand guard forward. If your hand only lightly touches the front guard or slips over it, the force may not be enough to trigger the chain brake. You should also maintain a firm grip of the chain saw handles while working. If you do and experience a kickback, your hand may never leave the front handle and will not activate the chain brake, or the chain brake will only activate after the saw has swung around a considerable distance. In such instances, the chain brake might not have enough time to stop the saw chain before it touches you. There are also certain positions in which your hand cannot reach the front hand guard to activate the chain brake; for example, when the saw chain is held in felling position. Will my inertia activated chain brake always activate during kickback in the event of a kickback? No. First your brake must be in working order. Testing the brake is simple, see instructions under the heading Checking, maintaining and servicing chain saw safety equipment. We recommend you do before you begin each work session. Second the kickback must be strong enough to activate the chain brake. If the chain brake is too sensitive it would activate all the time which would be a nuisance. Will my chain brake always protect me from injury in the event of a kickback? No. First, the chain brake must be in working order to provide the intended protection. Second, it must be activated during the kickback as described above to stop the saw chain. Third, the chain brake may be activated but if the bar is too close to you the brake might not have enough time to slow down and stop the chain before the chain saw hits you. Only you and proper working technique can eliminate kickback and its danger. Throttle lockout The throttle lockout is designed to prevent accidental operation of the throttle control. When you press the lock (A) (i.e. when you grasp the handle) it releases the throttle control (B). When you release the handle the throttle control and the throttle lockout both move back to their original positions. This arrangement means that the throttle control is automatically locked at the idle setting. (10) Chain catcher The chain catcher is designed to catch the chain if it snaps or jumps off. This should not happen if the chain is properly tensioned (see instructions under the heading Assembly) and if the bar and chain are properly serviced and maintained (see instructions under the heading General working instructions). (11) Right hand guard Apart from protecting your hand if the chain jumps or snaps, the right hand guard stops branches and twigs from interfering with your grip on the rear handle. (12) Vibration damping system Your machine is equipped with a vibration damping system that is designed to minimize vibration and make operation easier. The machine ′ s vibration damping system reduces the transfer of vibration between the engine unit/cutting equipment and the machine ′ s handle unit. The body of the chain saw, including the cutting equipment, is insulated from the handles by vibration damping units. Cutting hardwoods (most broadleaf trees) creates more vibration than cutting softwoods (most conifers). Cutting with cutting equipment that is blunt or faulty (wrong type or badly sharpened) will increase the vibration level. Stop switch Use the stop switch to switch off the engine. (13) ! WARNING! Overexposure to vibration can lead to circulatory damage or nerve damage in people who have impaired circulation. Contact your doctor if you experience symptoms of overexposure to vibration. Such symptoms include numbness, loss of feeling, tingling, pricking, pain, loss of strength, changes in skin colour or condition. These symptoms normally appear in the
GENERAL SAFETY PRECAUTIONS 12 – English 1155296-38 Rev.1 2012-11-19 Muffler The muffler is designed to keep noise levels to a minimum and to direct exhaust fumes away from the user. In areas with a hot, dry climate there is a high risk of fires. These areas are sometimes subject to government rules requiring among other things the muffler must be equipped with an approved type of spark arrestor mesh. (14) When fitting the mesh, make sure that the mesh is inserted in the right position. If necessary, use the combination spanner to insert or remove the mesh. Cutting equipment This section describes how to choose and maintain your cutting equipment in order to: • Reduce the risk of kickback. • Reduce the risk of the saw chain breaking or jumping off the bar. • Obtain optimal cutting performance. • Extend the life of cutting equipment. • Avoid increasing vibration levels. General rules • Only use cutting equipment recommended by us! See instructions under the heading Technical data. • Keep the chain’s cutting teeth properly sharpened! Follow our instructions and use the recommended file gauge. A damaged or badly sharpened chain increases the risk of accidents. • Maintain the correct depth gauge setting! Follow our instructions and use the recommended depth gauge clearance. Too large a clearance increases the risk of kickback.• Keep the chain properly tensioned! If the chain is slack it is more likely to jump off and lead to increased wear on the bar, chain and drive sprocket. • Keep cutting equipment well lubricated and properly maintained! A poorly lubricated chain is more likely to break and lead to increased wear on the bar, chain and drive sprocket. Cutting equipment designed to reduce kickback The only way to avoid kickback is to make sure that the kickback zone of the bar never touches anything. By using cutting equipment with ”built-in” kickback reduction and keeping the chain sharp and well- maintained you can reduce the effects of kickback. Guide bar The smaller the tip radius the lower the chance of kickback. Saw chain A chain is made up of a number of links, which are available in standard and low-kickback versions. Some terms that describe the bar and chain To maintain the safety features of the cutting equipment, you should replace a worn or damaged bar or chain with a bar and chain combinations recommended by Husqvarna. See instructions under the heading Technical Data for a list of replacement bar and chain combinations we recommend. Guide bar • Length (inches/cm) • Number of teeth on bar tip sprocket (T). • Chain pitch (inches). The spacing between the drive links of the chain must match the spacing of the teeth on the bar tip sprocket and drive sprocket. (15) • Number of drive links. The number of drive links is determined by the length of the bar, the chain pitch and the number of teeth on the bar tip sprocket. ! WARNING! The exhaust fumes from the engine are hot and may contain sparks which can start a fire. Never start the machine indoors or near combustible material! CAUTION! The muffler gets very hot during and after use. This also applies during idling. Be aware of the fire hazard, especially when working near flammable substances and/or vapours. ! WARNING! Never use a saw without a muffler, or with a damaged muffler. A damaged muffler may substantially increase the noise level and the fire hazard. Keep fire fighting equipment handy. If a spark arrestor screen is required in your area, never use the saw without or with a broken spark arrestor screen. ! WARNING! Faulty cutting equipment or the wrong combination of bar and saw chain increases the risk of kickback! Only use the bar/saw chain combinations we recommend, and follow the
GENERAL SAFETY PRECAUTIONS English – 131155296-38 Rev.1 2012-11-19• Bar groove width (inches/mm). The groove in the bar must match the width of the chain drive links. • Chain oil hole and hole for chain tensioner. The bar must be matched to the chain saw design. (16) Saw chain • Chain pitch (inches) (15) • Drive link width (mm/inches) (18) • Number of drive links. (17) Sharpening your chain and adjusting depth gauge setting General information on sharpening cutting teeth • Never use a blunt chain. When the chain is blunt you have to exert more pressure to force the bar through the wood and the chips will be very small. If the chain is very blunt it will produce wood powder and no chips or shavings. • A sharp chain eats its way through the wood and produces long, thick chips or shavings. • The cutting part of the chain is called the cutter and consists of a cutting tooth (A) and the depth gauge (B). The cutters cutting depth is determined by the difference in height between the two (depth gauge setting). (23) When you sharpen a cutting tooth there are four important factors to remember. 1 Filing angle (21) 2 Cutting angle (20) 3 File position (22) 4 Round file diameter It is very difficult to sharpen a chain correctly without the right equipment. We recommend that you use our file gauge. This will help you obtain the maximum kickback reduction and cutting performance from your chain. (22) See instructions under the heading Technical data for information about sharpening your chain. Sharpening cutting teeth To sharpen cutting teeth you will need a round file and a file gauge. See instructions under the heading Technical data for information on the size of file and gauge that are recommended for the chain fitted to your chain saw. • Check that the chain is correctly tensioned. A slack chain will move sideways, making it more difficult to sharpen correctly.• Always file cutting teeth from the inside face. Reduce the pressure on the return stroke. File all the teeth on one side first, then turn the chain saw over and file the teeth on the other side. • File all the teeth to the same length. When the length of the cutting teeth is reduced to 4 mm (5/32) the chain is worn out and should be replaced. (23) General advice on adjusting depth gauge setting • When you sharpen the cutting tooth (A) the depth gauge setting (C) will decrease. To maintain optimal cutting performance the depth gauge (B) has to be filed down to achieve the recommended depth gauge setting. See instructions under the heading Technical data to find the correct depth gauge setting for your particular chain. (24) Adjustment of depth gauge setting • The cutting teeth should be newly sharpened before adjusting the depth gauge setting. We recommend that you adjust the depth gauge setting every third time you sharpen the cutting teeth. NOTE! This recommendation assumes that the length of the cutting teeth is not reduced excessively. • You will need a flat file and a depth gauge tool. We recommend that you use our depth gauge tool to acheive the correct depth gauge setting and bevel for the depth gauge. • Place the depth gauge tool over the chain. Detailed information regarding the use of the depth gauge tool, will be found on the package for the depth gauge tool. Use the flat file to file off the tip of the depth gauge that protrudes through the depth gauge tool. The depth gauge setting is correct when you no longer feel resistance as you draw the file along the depth gauge tool. (24) Tensioning the chain The more you use a chain the longer it becomes. It is therefore important to adjust the chain regularly to take up the slack. ! WARNING! Departure from the sharpening instructions considerably increases the risk of kickback. ! WARNING! The risk of kickback is increased if the depth gauge setting is too large! ! WARNING! A slack chain may jump off and cause serious or even fatal injury.
GENERAL SAFETY PRECAUTIONS 14 – English1155296-38 Rev.1 2012-11-19 Check the chain tension every time you refuel. NOTE! A new chain has a running-in period during which you should check the tension more frequently. Tension the chain as tightly as possible, but not so tight that you cannot pull it round freely by hand. (25) 135 • Loosen the bar nut that holds the clutch cover and chain brake. Use the combination spanner. Then retighten the bar nut as tightly as you can by hand. (26) • Raise the tip of the bar and stretch the chain by tightening the chain tensioning screw using the combination spanner. Tighten the chain until it does not sag from the underside of the bar. (27) • Use the combination spanner to tighten the bar nut while holding up the tip of the bar. Check that you can pull the saw chain round freely by hand, and that there is no slack on the underside of the bar. (28) The position of the chain tensioning screw on our chain saws varies from model to model. See instructions under the heading What is what? to find out where it is on your model. 135e, 135e TrioBrake • Release the knob by folding it out. (29) • Turn the knob anti clockwise to loosen the bar cover. (30) • Adjust the tension on the chain by turning the wheel down (+) for tighter tension and up (-) to loosen the tension. (31) • Tighten the bar clutch by turning the knob clockwise. (32) • Fold the knob back in to lock the tensioning. (33) Lubricating cutting equipment Chain oil Chain oil must demonstrate good adhesion to the chain and also maintain its flow characteristics regardless of whether it is warm summer or cold winter weather. As a chain saw manufacturer we have developed an optimal chain oil which, with its vegetable oil base, is also biodegradable. We recommend the use of our own oil for both maximum chain life and to minimise environmental damage. If our own chain oil is not available, standard chain oil is recommended. Never use waste oil! Using waste oil can be dangerous to you and damage the machine and environment. Filling with chain oil • All our chain saws have an automatic chain lubrication system. On some models the oil flow is also adjustable. • The saw chain oil tank and the fuel tank are designed so that the fuel runs out before the saw chain oil. However, this safety feature requires that you use the right sort of chain oil (if the oil is too thin it will run out before the fuel), and that you adjust the carburetor as recommended (a lean mixture may mean that the fuel lasts longer than the oil) and that you also use the recommended cutting equipment (a bar that is too long will use more chain oil). Checking chain lubrication • Check the chain lubrication each time you refuel. See instructions under the heading Lubricating the bar tip sprocket. Aim the tip of the bar at a light coloured surface about 20 cm (8 inches) away. After 1 minute running at 3/4 throttle you should see a distinct line of oil on the light surface. If the chain lubrication is not working: • Check that the oil channel in the bar is not obstructed. Clean if necessary. (34) • Check that the groove in the edge of the bar is clean. Clean if necessary. (35) • Check that the bar tip sprocket turns freely and that the lubricating hole in the tip sprocket is not blocked. Clean and lubricate if necessary. (36) If the chain lubrication system is still not working after carrying out the above checks and associated measures you should contact your service agent. Chain drive sprocket The clutch drum is fitted with one of the following drive sprockets: A Spur sprocket (the chain sprocket is welded on the drum) B Rim sprocket (replaceable) (37) Regularly check the degree of wear on the drive sprocket. Replace if wear is excessive. Replace the drive sprocket whenever you replace the chain. ! WARNING! Poor lubrication of cutting equipment may cause the chain to snap, which could lead to serious, even fatal injuries. IMPORTANT! When using vegetable based saw chain oil, dismantle and clean the groove in the bar and saw chain before long-term storage. Otherwise there is a risk of the saw chain oil oxidizing, which will result in the saw chain becoming stiff and the bar tip sprocket jamming.
GENERAL SAFETY PRECAUTIONS English – 151155296-38 Rev.1 2012-11-19Needle bearing lubrication Both versions of sprockets have a needle bearing on the drive shaft, which has to be greased regularly (once a week). CAUTION! Use a high-quality bearing grease or engine oil. See instructions under the heading Maintenance, Needle bearing lubrication. Checking wear on cutting equipment Check the chain daily for: • Visible cracks in rivets and links. • Whether the chain is stiff. • Whether rivets and links are badly worn. Replace the saw chain if it exhibits any of the points above. We recommend you compare the existing chain with a new chain to decide how badly the existing chain is worn. When the length of the cutting teeth has worn down to only 4 mm the chain must be replaced. Guide bar Check regularly: • Whether there are burrs on the edges of the bar. Remove these with a file if necessary. • Whether the groove in the bar has become badly worn. Replace the bar if necessary. • Whether the tip of the bar is uneven or badly worn. If a hollow forms on the underside of the bar tip this is due to running with a slack chain. • To prolong the life of the bar you should turn it over regularly. ! WARNING! Most chain saw accidents happen when the chain touches the operator. Wear personal protective equipment. See instructions under the ”Personal protective equipment” heading. Do not tackle any job that you feel you are not adequately trained for. See instructions under the headings Personal protective equipment, How to avoid kickback, Cutting equipment and General working instructions. Avoid situations where there is a risk of kickback. See instructions under the heading Machine ′′′ ′s safety equipment. Use the recommended protective equipment and check its condition. See instructions under the heading General working instructions. Check that all the chain saw safety features are working. See instructions under the headings General working instructions and General safety precautions.

FUEL HANDLING English – 171155296-38 Rev.1 2012-11-19 Fuel Note! The machine is equipped with a two-stroke engine and must always be run using a mixture of petrol and two- stroke oil. It is important to accurately measure the amount of oil to be mixed to ensure that the correct mixture is obtained. When mixing small amounts of fuel, even small inaccuracies can drastically affect the ratio of the mixture. Petrol • Use good quality unleaded or leaded petrol. • The lowest recommended octane grade is 90 (RON). If you run the engine on a lower octane grade than 90 so-called knocking can occur. This gives rise to a high engine temperature and increased bearing load, which can result in serious engine damage. • When working with continuous high revs (e.g. limbing) a higher octane is recommended. Environment fuel HUSQVARNA recommends the use of alkylate fuel, either Aspen two-stroke fuel or environmental fuel for four-stroke engines blended with two-stroke oil as set out below. Note that carburettor adjustment may be necessary when changing the type of fuel (see the instructions under the heading Carburettor). Ethanol fuel HUSQVARNA recommends commercial available fuel with maximum 10% ethanol content. Running-in Avoid running at a too high speed for extended periods during the first 10 hours. Two-stroke oil • For best results and performance use HUSQVARNA two-stroke engine oil, which is specially formulated for our air-cooled two-stroke engines. • Never use two-stroke oil intended for water-cooled engines, sometimes referred to as outboard oil (rated TCW). • Never use oil intended for four-stroke engines. • A poor oil quality and/or too high oil/fuel ratio may jeopardise function and decrease the life time of catalytic converters.Mixing ratio 1:50 (2%) with HUSQVARNA two-stroke oil. 1:33 (3%) with oils class JASO FB or ISO EGB formulated for air-cooled, two-stroke engines. Mixing • Always mix the petrol and oil in a clean container intended for fuel. • Always start by filling half the amount of the petrol to be used. Then add the entire amount of oil. Mix (shake) the fuel mixture. Add the remaining amount of petrol. • Mix (shake) the fuel mixture thoroughly before filling the machine’s fuel tank. • Do not mix more than one month’s supply of fuel at a time. • If the machine is not used for some time the fuel tank should be emptied and cleaned. Chain oil • We recommend the use of special oil (chain oil) with good adhesion characteristics. (43) • Never use waste oil. This results in damage to the oil pump, the bar and the chain. • It is important to use oil of the right grade (suitable viscosity range) to suit the air temperature. • In temperatures below 0°C (32°F) some oils become too viscous. This can overload the oil pump and result in damage to the oil pump components. • Contact your service agent when choosing chain oil. ! WARNING! Always ensure there is adequate ventilation when handling fuel. Petrol, litre Two-stroke oil, litre 2% (1:50) 3% (1:33) 5 0,10 0,15 10 0,20 0,30 15 0,30 0,45 20 0,40 0,60
FUEL HANDLING 18 – English1155296-38 Rev.1 2012-11-19 Fueling Clean the area around the fuel cap. Clean the fuel and chain oil tanks regularly. The fuel filter must be replaced at least once a year. Contamination in the tanks causes malfunction. Make sure the fuel is well mixed by shaking the container before refuelling. The capacities of the chain oil tank and fuel tank are carefully matched. You should therefore always fill the chain oil tank and fuel tank at the same time. (43) Fuel safety • Never refuel the machine while the engine is running. • Make sure there is plenty of ventilation when refuelling or mixing fuel (petrol and 2-stroke oil). • Move the machine at least 3 m from the refuelling point before starting it. • Never start the machine: 1 If you have spilt fuel or chain oil on the machine. Wipe off the spillage and allow remaining fuel to evaporate. 2 If you have spilt fuel on yourself or your clothes, change your clothes. Wash any part of your body that has come in contact with fuel. Use soap and water. 3 If the machine is leaking fuel. Check regularly for leaks from the fuel cap and fuel lines. Transport and storage • Always store the chain saw and fuel so that there is no risk of leakages or fumes coming into contact with sparks or naked flames from electrical equipment, electric motors, relays/switches, boilers and the like. • Always store fuel in an approved container designed for that purpose. • For longer periods of storage or for transport of the chain saw, the fuel and chain oil tanks should be emptied. Ask where you can dispose of waste fuel and chain oil at your local petrol station. • The guide bar cover must always be fitted to the cutting attachment when the machine is being transported or in storage, in order to prevent accident contact with the sharp chain. Even a non-moving chain can cause serious cuts to yourself or persons you bump into with an exposed chain. • Remove the spark plug cap from the spark plug. Activate the chain brake. • Secure the machine during transport. Long-term storage Empty the fuel/oil tanks in a well ventilated area. Store the fuel in approved cans in a safe place. Fit the guide bar cover. Clean the machine. See instructions under the heading Maintenance schedule. Ensure the machine is cleaned and that a complete service is carried out before long-term storage. ! WARNING! Taking the following precautions, will lessen the risk of fire: Do not smoke and do not place any hot objects in the vicinity of fuel. Always stop the engine and let it cool for a few minutes before refuelling. When refuelling, open the fuel cap slowly so that any excess pressure is released gently. Tighten the fuel cap carefully after refuelling. Always move the machine away from the refuelling area and source before starting. ! WARNING! Fuel and fuel vapour are highly flammable. Take care when handling fuel and chain oil. Be aware of the risks of fire, explosion and those associated with inhalation. ! WARNING! Never use a machine with visible damage to the spark plug guard and ignition cable. A risk of sparking arises, which can cause a
STARTING AND STOPPING English – 191155296-38 Rev.1 2012-11-19 Starting and stopping Starting The chain brake must be engaged when the chain saw is started. Activate the brake by moving the front hand guard forwards. (48) Cold engine Start position, 1: Set the start/stop switch in the choke position by pulling the red control outward - upward. (44) Air purge, 2: Press the air purge diaphragm repeatedly until fuel fills the diaphragm (at least 6 times). The diaphragm need not be completely filled. (44) Grip the front handle with your left hand. Hold the chain saw on the ground by placing your right foot through the rear handle. (45) Pull the starter handle, 3: Pull the starter handle with your right hand and pull out the starter cord slowly until you feel a resistance (as the starter pawls engage) then pull firmly and rapidly until the engine fires. Push down the red choke control, 4: As soon as the engine fires which can be heard through a puff sound, push down on the red choke control. (47) Pull the starter handle, 5: Keep on pulling the cord powerfully until the engine starts. Warm engine Start position, 1: The correct choke/start throttle setting for warm starting is obtained by initially moving the choke control by pulling the red control outward - upwards. (44) Air purge, 2: Press the air purge diaphragm repeatedly until fuel fills the diaphragm (at least 6 times). The diaphragm need not be completely filled. (44) Push down the red choke control, 4: This inactivates the choke, which is not needed when starting a warm chain saw. However the movement of the start/stop switch will have engaged a high idle, making warm starting easier. (47)Pull the starter handle, 5: Grip the front handle with your left hand. Hold the chain saw on the ground by placing your right foot through the rear handle. (45) Pull the starter handle with your right hand and pull out the starter cord slowly until you feel a resistance (as the starter pawls engage) then pull firmly and rapidly until the engine starts. As the chain brake is still engaged the speed of the engine must be set to idling as soon as possible, this is achieved by disengaging the throttle lock. Disengagement is done by gently touching on the throttle trigger. This prevents unnecessary wear to the clutch, clutch drum and brake band. Allow the machine to idle a few seconds before giving full throttle. There is a simplified start reminder with illustrations to describe each step on the rear edge of the saw (A). (44) CAUTION! Do not pull the starter cord all the way out and do not let go of the starter handle when the cord is fully extended. This can damage the machine. Note! Pull the front hand guard towards the front handle. The chain brake is now disengaged. Your chain saw is now ready for use. (38) • Never start a chain saw unless the bar, chain and all covers are fitted correctly. See instructions under the heading Assembly. Without a bar and chain attached to the chain saw the clutch can come loose and cause serious injury. • The chain brake should be activated when starting. Se instructions under the heading Start and stop. Do not drop start. This method is very dangerous because you may lose control of the saw. (48) • Never start the machine indoors. Exhaust fumes can be dangerous if inhaled. • Observe your surroundings and make sure that there is no risk of people or animals coming into contact with the cutting equipment. • Always hold the saw with both hands. The right hand should be on the rear handle, and the left hand on the front handle. All people, whether right or left handed, should use this grip. Use a firm grip with thumbs and fingers encircling the chain saw handles. • The chain brake is released by moving the front hand guard marked ”PULL BACK TO RESET” back, towards the front handle. Stopping Stop the engine by pushing the start/stop switch down. (13) CAUTION! The start/stop switch automatically returns to run position. To avoid involuntary start up, the spark plug cap must always be removed from the spark plug when the machine is unsupervised. (49) ! WARNING! Note the following before starting: The chain brake must be engaged when the chain saw is started to reduce the chance of contact with the moving chain during starting. Never start a chain saw unless the bar, chain and all covers are fitted correctly. Otherwise the clutch can come loose and cause personal injuries. Place the machine on firm ground. Make sure you have a secure footing and that the chain cannot touch anything. Keep people and animals well away from the working area. Never twist the starter cord around your hand. ! WARNING! Long term inhalation of the engine
WORKING TECHNIQUES 20 – English1155296-38 Rev.1 2012-11-19 Before use: (50) 1 Check that the chain brake works correctly and is not damaged. 2 Check that the rear right hand guard is not damaged. 3 Check that the throttle lockout works correctly and is not damaged. 4 Check that the stop switch works correctly and is not damaged. 5 Check that all handles are free from oil. 6 Check that the anti vibration system works and is not damaged. 7 Check that the muffler is securely attached and not damaged. 8 Check that all parts of the chain saw are tightened correctly and that they are not damaged or missing. 9 Check that the chain catcher is in place and not damaged. 10 Check the chain tension. General working instructions Basic safety rules 1 Look around you: • To ensure that people, animals or other things cannot affect your control of the machine. • To make sure that none of the above might come within reach of your saw or be injured by falling trees. CAUTION! Follow the instructions above, but do not use a chain saw in a situation where you cannot call for help in case of an accident. 2 Do not use the machine in bad weather, such as dense fog, heavy rain, strong wind, intense cold, etc. Working in bad weather is tiring and often brings added risks, such as icy ground, unpredictable felling direction, etc.3 Take great care when removing small branches and avoid cutting bushes (i.e. cutting many small branches at the same time). Small branches can be grabbed by the chain and thrown back at you, causing serious injury. 4 Make sure you can move and stand safely. Check the area around you for possible obstacles (roots, rocks, branches, ditches, etc.) in case you have to move suddenly. Take great care when working on sloping ground. 5 Take great care when cutting a tree that is in tension. A tree that is in tension may spring back to its normal position before or after being cut. If you position yourself incorrectly or make the cut in the wrong place the tree may hit you or the machine and cause you to lose control. Both situations can cause serious personal injury. 6 Before moving your chain saw switch off the engine and lock the chain using the chain brake. Carry the chain saw with the bar and chain pointing backwards. Fit a guard to the bar before transporting the chain saw or carrying it for any distance. 7 When you put the chain saw on the ground, lock the saw chain using the chain brake and ensure you have a constant view of the machine. Switch the engine off before leaving your chain saw for any length of time. General rules 1 If you understand what kickback is and how it happens then you can reduce or eliminate the element of surprise. By being prepared you reduce the risk. Kickback is usually quite mild, but it can sometimes be very sudden and violent. 2 Always hold the chain saw firmly with your right hand on the rear handle and your left hand on the front handle.
