1. Carry the chain saw with the engine stopped the guide bar and saw chain to the rear and the muffler away from your body Do not operate a chain saw that is damaged improperly adjusted or not completely and securely assembled Be sure that the saw chain stops moving when the throttle control trigger is released Shut off the engine before setting the chain saw down Use extreme caution when cutting small size brush and saplings because slender material may catch the saw chain and be whipped toward you or pull you off balance When cutting a limb that is under tension be alert for springback so that you will not be struck when the tension in the wood fibers is released Keep handles dry clean and free of oil or fuel mixture Operate the chain saw only in well ventilated areas Do not operate a chain saw in a tree unless you have been specifically trained to do so Do not operate a chain saw above shoulder height All chain saw service other than the items listed in the operator s owner s safety and maintenance instructions should be performed by competent chain saw service personnel For example if improper tools are used to remove the flywheel or if an improper tool is used to hold the flywheel in order to remove the clutch structural damage to the flywheel could occur and subsequently cause the flywheel to burst When transporting your chain saw use the appropriate guide bar guard Note This Annex is inten
2. 5 be a danger you may be surprised and lose control of the saw Never saw stacked logs or branches without first separating them Only saw one log or one piece at a time Remove the cut pieces to keep your working area safe Never use the chain saw above shoulder height and avoid cutting with the tip of the bar Never use the chain saw one handed In order to keep control of your saw always maintain a firm foothold Never work on a ladder in a tree or on any other insecure support Always use a fast cutting speed i e full throttle Take great care when you cut with the top edge of the bar i e when cutting from the underside of the object This is known as cutting with a pushing chain The chain tries to push the chain saw back towards the user If the saw chain is jamming the saw may be pushed back at you WORKING TECHNIQUES 8 Unless the user resists this pushing force there Is a risk that the chain saw will move so far backwards that only the kickback zone of the bar is in contact with the tree which can lead to a kickback Cutting with the bottom edge of the bar i e from the top of the object downwards is known as cutting with a pulling chain In this case the chain saw pulls itself towards the tree and the front edge of the chain saw body rests naturally on the trunk when cutting Cutting with a pulling chain gives the operator better control over the chain saw and the position of the kickback

English e Never start the machine 1 If you have spilled fuel or chain oil on the machine Wipe off the spillage and allow remaining fuel to evaporate 2 Ifyou have spilled 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 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 fire Transport and storage e 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 e Always store fuel in an approved container designed for that purpose e 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 gas station e Ensure the machine is cleaned and that a complete service is carried out before long term storage e The bar guard 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 ch

5. e 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 e 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 e 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 Tensioning the chain aed WARNING A slack chain may jump off the bar and cause serious or even fatal injury The more you use a chain the longer it becomes It is therefore important to adjust the chain regularly to take up the slack 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 o l r am e e Loosen the bar nuts that hold the clutch cover chain brake Use the combination
6. go Make sure that the area in which you are cutting is free from obstacles Do not let the nose of the guide bar contact a log branch or any other obstacle which could be hit while you are operating the saw Cut at high engine speeds Do not overreach or cut above shoulder height Follow manufacturer s sharpening and maintenance instructions for the saw chain Only use replacement bars and chains specified by the manufacturer or the equivalent 40 English Other safety precautions WARNING Do not operate a chain saw with one hand Serious injury to the operator helpers bystanders or any combination of these persons may result from one handed operation A chain saw is intended for two handed use Do not operate a chain saw when you are fatigued Use safety footwear snug fitting clothing protective gloves and eye hearing and head protection devices Use caution when handling fuel Move the chain saw at least 10 feet 3 m from the fueling point before starting the engine Do not allow other persons to be near the chain saw when starting or cutting with the chain saw Keep bystanders and animals out of the work area Do not start cutting until you have a clear work area secure footing and a planned retreat path from the falling tree Keep all parts of your body away from the saw chain when the engine is running Before you start the engine make sure that the saw chain is not contacting anything
7. Two factors decide whether the chain will jam or the object that you are cutting will split the first is how the object is supported before and after cutting and the second is whether it is in tension In most cases you can avoid these problems by cutting in two stages from the top and from the bottom You need to support the object so that it will not trap the chain or split during cutting IMPORTANT If the chain jams in the cut stop the engine Don t try to pull the chain saw free If you do you may be injured by the chain when the chain saw suddenly breaks free Use a lever to open up the cut and free the chain saw The following instructions describe how to handle the common situations you are likely to encounter when using a chain saw Limbing When limbing thick branches you should use the same approach as for cutting Cut difficult branches piece by piece English 23 WORKING TECHNIQUES Cutting WARNING Never attempt to cut logs while they are in a pile or when a couple of logs are lying together Such procedures drastically increase the risk of kickback which can result in a serious or fatal injury If you have a pile of logs each log you attempt to cut should be removed from the pile placed on a saw horse or runners and cut individually Remove the cut pieces from the cutting area By leaving them in the cutting area you increase the risk for inadvertently getting a kickback as well as
