Improperly tensioned or lubricated chain may either break or increase the chance for kickback. 10. Only use replacement bars and chains specified by the manufacturer. Incorrect replacement bars and chains may cause chain breakage and/or kickback. 11. Follow the manufacturer’s sharpening and maintenance instructions for the saw chain. Decreasing the depth gauge height can lead to increased kickback. ! WARNING: Follow all safety rules to help prevent Kickback which can cause serious personal injury. AVOID KICKBACK AND PULL-IN KICKBACK Kickback Path Avoid Obstructions Clear The Work Area 1. KICKBACK is the backward, upward or sudden forward motion of the guide bar occurring when the saw chain near the upper tip of the guide bar contacts any object such as a log or branch, or when the wood closes in and pinches chain in the cut. Contacting a foreign object in the wood can also result in loss of chain saw control. 2. ROTATIONAL KICKBACK can occur when the moving chain contacts an object at the upper tip of the guide bar. This contact can cause the chain to dig into the object, which stops the chain for an instant. The result is a lightning fast, reverse reaction which kicks the guide bar up and back toward the operator. 3. PINCH-KICKBACK can occur when the wood closes in and pinches the moving saw chain in the cut along the top of the guide bar and the saw chain is suddenly stopped. This sudden stopping of the chain results in a reversal of the chain force used to cut wood and causes the saw to move in the opposite direction of the chain rotation. The saw is driven straight back toward the operator. 10 ADDITIONAL RULES FOR SAFE OPERATION cont. SAFETY INSTRUCTIONS cont. AVOID KICKBACK AND PULL-IN cont. 4. PULL-IN can occur when the moving chain contacts a foreign object in the wood in the cut along the bottom of the guide bar and the saw chain is suddenly stopped. This sudden stopping pulls the saw forward and away from the operator and could easily cause the operator to lose control of the saw. CAUSES AND OPERATOR PREVENTION OF KICKBACK: • Kickback may occur when the nose or tip of the guide bar touches an object, or when the wood closes in and pinches the saw chain in the cut. • Tip contact in some cases may cause a sudden reverse reaction, kicking the guide bar up and back towards the operator. • Pinching the saw chain along the top of the guide bar may push the guide bar rapidly back towards the operator. • Either of these reactions may cause you to lose control of the saw which could result in serious personal injury. • Do not rely exclusively upon the safety devices built into your saw. • As a chain saw user, you should take several steps to keep your cutting jobs free from accident or injury. • Kickback is the result of tool misuse and/or incorrect operating procedures or conditions and can be avoided by taking proper precautions as given below: - Maintain a firm grip, with thumbs and fingers encircling the chain saw handles, with both hands on the saw and position your body and arm to allow you to resist kickback forces. Kickback forces can be controlled by the operator, if proper precautions are taken. - Do not let go of the chain saw. - Do not overreach and do not cut above shoulder height. This helps prevent unintended tip contact and enables better control of the chain saw in unexpected situations. AVOID PINCH-KICKBACK 1. Be extremely aware of situations or obstructions that can cause material to pinch the top of or otherwise stop the chain. 2. Do not cut more than one log at a time. 3. Do not twist the saw as the bar is withdrawn from an undercut when bucking. AVOID PULL-IN 1. Always begin cutting with the saw at full speed and the saw housing against wood. 2. Use wedges made of plastic or wood. Never use metal to hold the cut open. ! WARNING: Follow all safety rules to help prevent Kickback which can cause serious personal injury. 11 ADDITIONAL RULES FOR SAFE OPERATION cont. SAFETY INSTRUCTIONS cont. SAFETY INSTRUCTIONS cont. CHAIN BRAKE (Built-In, Automatic and Manual Systems) See page 21, Figs. 8-9 MAINTAIN CONTROL ! 1. Chain Brake: This Chain Saw is designed to stop tile chain in the event of kickback. Both built-in, Automatic and Manual Chain Brake Systems reduce kick-back. WARNING: ! WARNING: NEVER REVERSE HAND POSITIONS STAND TO THE LEFT OF SAW Thumb on underside of handlebar Elbow Locked 1. A good, firm grip on the saw with both hands will help you maintain control. Don't let go. Grip the rear handle with your right hand whether you are right or left handed. Wrap the fingers of your left hand over and around the front handlebar, and your left thumb under the front handlebar. Keep your left arm straight with the elbow locked. 2. Position your left hand on the front handlebar so it is in a straight line with your right hand on the rear handle when making bucking cuts. Stand slightly to the left side of the saw to keep your body from being in a direct line with the cutting chain. 3. Stand with your weight evenly balanced on both feet. 4. Do not overreach. You could be drawn or thrown off balance and lose control. 5. Do not cut above shoulder height. It is difficult to maintain control of saw above shoulder height. KICKBACK SAFETY FEATURES ! WARNING: The following features are included on your saw to help reduce hazard of kickback; however, such features will not totally eliminate this danger. Do not rely only on safety devices. Follow all safety rules to help avoid kickback and other forces which can result in serious injury. 1. Hand Guard: designed to reduce the chance of your left hand contacting the chain if your hand slips off the front handlebar. 2. Position of Front and Rear Handle Bars AVOID KICKBACK: designed with distance between handles and "in-line" with each other. The spread and "in-line" position of the hands provided by this design work together to give balance and resistance in controlling the pivot of the saw back toward the operator if kick back occurs. 3. Reduced-Kickback Guide Bar: designed with a small radius tip which reduces the size of the kickback danger zone on the bar tip, see Fig. A below. This type of bar has been demonstrated to significantly reduce the number and seriousness of kickbacks when tested in accordance with ANSI B175.1. 4. Low Kickback Chain has met kickback performance requirements when tested on the representative sample of these chain saws specified in ANSI B175.1. See Fig. B below. Reduced Kickback Guide Bar ADDITIONAL RULES FOR SAFE OPERATION cont. Fig. A Low Kickback Chain Fig. B Contoured Depth Gauge Small Radius Tip Guide Bar Elongated Guard Link deflects kickback force and allows wood to gradually ride into cutter Large Radius Tip Guide Bar 12 ! WARNING: WE DO NOT REPRESENT AND YOU SHOULD NOT ASSUME THAT THE CHAIN BRAKE WILL PROTECT YOU IN THE EVENT OF A KICKBACK. Kickback is a lightning fast action which throws the bar and rotating chain back and up toward the operator. Kickback can be caused by allowing contact of the bar tip in the danger zone with any hard object. Kickback can also be caused by pinching the saw chain along the top of the guide bar. This action may push the guide bar rapidly back toward the operator. Either of these events may cause you to lose control of the saw which could result in serious injury or even death. DO NOT RELY UPON ANY OF THE SAFETY DEVICES BUILT INTO YOUR SAW. YOU SHOULD USE THE SAW PROPERLY AND CAREFULLY TO AVOID KICKBACK. Reduced-Kickback guide bars and low-kickback saw chains reduce the chance and magnitude of kickback and are recommended. Your saw has a low kickback chain and bar as original equipment. Repairs on a chain brake should be made by a qualified service dealer or repair center. Take your unit to the place of purchase if purchased from a servicing dealer, or to your nearest qualified service dealer or repair center. 2. PUSH hand guard forward to activate the chain brake MANUALLY. RELEASE the trigger switch to activate chain brake AUTOMATICALLY. IMPORTANT: Please see page 21, figures 8 and 9 for detailed instructions. WARNING: • Tip contact in some cases may cause a lightning fast REACTION, kicking the guide bar up and back toward the operator. • Pinching the saw chain along the tip of the guide bar may push the guide bar rapidly back towards the operator. • Either of these reactions may cause you to lose control of the saw which could result in serious injury. Do not rely exclusively upon devices built into your saw. ! ! CAUTION: Exposure to vibrations through prolonged use of hand tools could cause blood vessel or nerve damage in the fingers, hands, and joints of people prone to circulation disorders or abnormal swelling. Prolonged use in cold weather has been linked to blood vessel damage in otherwise healthy people. If symptoms occur such as numbness, pain, loss of strength, change in skin color or texture, or loss of feeling in the fingers, hands, or joints, discontinue the use of this tool and seek medical attention.

INTENDED USE The chain saw is intended for wood: sawing of trees, tree trunks, branches, wooden beams, planks, etc. Cuts can be sawed with or across the grain. This product is not suitable for sawing mineral materials, plastics or non-wood building materials. ASSEMBLY NOTE: This Chain Saw comes fully assembled, including the Chain /Chain Bar Assembly. Included is an extra Chain. See below for Chain/Chain Bar Replacement. ! WARNING: Do not connect the chain saw to extension cord and power source before it is completely assembled. Always use gloves when handling the chain. CHAIN AND CHAIN BAR ASSEMBLY/REPLACEMENT (See Figs. 4a, 4b, 4c, 4d and Pgs 14-15 for part reference) 1. Place the chain saw on any suitable flat surface. 2. (See Fig. 4a) Slide the chain (8) in the slot around the guide bar (7). Ensure chain is in correct running direction by comparing with chain symbol (15). Ensure the chain tensioning catch (16) is facing outwards. 3. (See Fig. 4b) Fit the chain onto the drive sprocket (13) and guide the guide bar (7), so that the fastening bolt (18) and the two guide fins (14) fit into the keyway of the guide bar (7). Fig. 4a 8 16 TENSIONING CHAIN/LOCKING KNOB Always check the chain tension before use, after the first cuts and regularly during use. Upon initial operation, new chains can lengthen considerably. Fig. 4d ! WARNING: Unplug chain saw from power source before adjusting saw chain tension. ! WARNING: Cutting edges on chain are sharp. Use protective gloves when handling chain. ! WARNING: ALWAYS Maintain proper chain tension. A loose chain will increase the risk of kickback. A loose chain may jump out of guide bar groove. This may injure operator and damage chain. A loose chain will cause chain, chain bar, and sprocket to wear rapidly. The chain life of the saw chain mainly depends upon sufficient lubrication and correct tensioning. Avoid tensioning the chain if it is hot, as this will cause the chain to become over tensioned when it cools down. Fig. 4b 13 14 7 18 4. Check to make sure all parts are seated properly and hold chain and guide bar in a level position. (See Fig. 4c) 5. Fit cover plate, ensure that the chain catcher (17) fits into the groove of the cover plate (12). (See Figs. 2 & 3, pg.15) 6. Press the cover plate firmly onto the machine and screw on the cover plate (12) with the locking knob (11). (See Fig. 2, pg.15) NOTE: The chain is not yet tensioned. Tensioning the chain applies as described under “Tensioning chain”. 16 Fig. 4c Fig. 5 1. Place the chain saw on any suitable flat surface. 2. Turn the locking knob/ chain tensioning knob clockwise until the locking knob is screwed tightly, (See Fig. 4d). The correct chain tension will be reached automatically. The ratchet mechanism prevents the chain tension from loosening. NOTE: Use one hand 3. The correct chain tension is reached when the chain to raise chain. can be raised approx. 3-6 mm (1/8 to 1/4-in.) from the chain bar in the centre. This should be done by using one hand to raise the chain against the weight of the machine. (See Fig. 5) 4. When the chain loosens, unscrew the locking knob/chain tensioning knob absolutely and then Screw on the cover plate with the locking knob tightly again. Cover Plate 17 approx. 3-6 mm (1/8 to 1/4-in.) ASSEMBLY & ADJUSTMENTS cont. LUBRICATION ! CAUTION: The chain saw is NOT supplied filled with oil. It is essential to fill with oil before use. Never operate the chain saw without chain oil or at an empty oil tank level, as this will result in extensive damage to the product. Chain life and cutting capacity depends on optimum lubrication. Therefore, the chain is automatically oiled during operation via oil outlet Filling oil tank: (See Fig. 6) 1. Set chain saw on any suitable surface with oil filler cap facing upward. 2. Clean area around the Oil Filler Cap with cloth and unscrew the cap by turning it counter clockwise. 3. Add bar and chain oil (Craftsman Bar & Chain Oil, SAE30) until reservoir is full. 4. Avoid dirt or debris entering oil tank, re-screw oil filler cap and tighten. Fig. 6 ! CAUTION: To allow venting of the oil reservoir, small breather channels are provided between the oil filler cap and the strainer. To prevent leakage, ensure machine is left in a horizontal position (oil filler cap uppermost) when not in use. It is important to use only the recommended oil to avoid damage to the chain saw. Never use recycled/old oil. Use of non approved oil will invalidate the warranty. 18 CHAINSAW OPERATION TERMS Bucking – The process of cross cutting a felled tree or log into lengths.

OPERATION SWITCHING ON AND OFF (Fig. 8) ATTACHING EXTENSION CORD 1. Insert extension cord socket into Chain Saw’s Plug (Fig. 7a). 2. An Extension Cord Retainer is attached to the Handle to reduce strain on the cord. To use this feature, simply double the extension cord as shown, about a foot from the end, and insert it into the end of the Retainer. Place the loop formed by doubling the cord over the Hook (Fig. 7b). Gently tug on the cord to ensure that it is firmly situated in the Retainer (Fig. 7c). 3. Keep extension cord clear of operator, unit and any obstacles at all times. Do not expose the cord to heat, oil, water, or sharp edges. Fig. 7a ! WARNING: Check the voltage and electric current supply: The voltage and current supply must comply with the ratings on the data plate. 1. To switch the Chain Saw ON, press the lock-off button, then fully press the on/off switch (2) and hold in this position. The lock-off button (3) can now be released. 2. To switch the Chain Saw OFF, release the on/off switch (2). Do not stop chain saw after sawing by activating the front hand guard (manual chain brake). Lock-off (3) Fig. 8 On/Off switch (2) (trigger) THE CHAIN BREAK (Built-In, Manual and Automatic and Systems) (Figs. 8 and 9) Fig. 7b The MANUAL chain brake is a safety mechanism activated through the front hand guard (6) when kickback occurs. Chain stops immediately. The following function check should be carried out at regular intervals. 1. MANUAL CHAIN BRAKE (See Fig. 9): PUSH front hand guard (6) forward (position 2 ) and try starting the chain saw. The chain must not start.

AUTOMATIC CHAIN BRAKE: RELEASE the On/Off (trigger) switch to activate chain brake AUTOMATICALLY, (See Fig. 8 for On/Off switch location). 6 Hand Guard Pos. 1 Pos. 1 Pos. 2 Cord locked in Extension Cord Retainer Fig. 9 20 21 OPERATION cont. OPERATION cont. CUTTING Check oil level gauge prior to starting and regularly during operation. Refill oil when oil level is low. The oil tank filling will last approx. 16 minutes, depending on sawing intensity and stops. (See Fig. 6 on page 18) Confirm the chain tension is in working order and the chain sharp. Check new replaced chain tension during operation. Upon initial operation, new chains can lengthen considerably. The condition of the chain influences the cutting performance. Only a sharp chain protects from overload. Make sure you are wearing the necessary protective equipment. Wear safety glasses/goggles/visor – safety helmet and hearing protection. Further protective equipment for head, hands, legs and feet is highly recommended. Adequate protective clothing will reduce personal injury by flying debris or accidental contact with saw chain. Proper functioning of the automatic oiler can be checked by running the chain saw and pointing the tip of the chain bar towards a piece of cardboard or paper on the ground. ! GENERAL CUTTING Always hold the chain saw firmly with both hands. Front grip with the left hand and rear grip with the right hand. Fully grip both handles at all times during operation. (See Figs. 11 and 12) Never operate chain saw using only one hand. Ensure power cord is located to the rear, away from the chain and wood and so positioned that it will not be caught on branches or the like during cutting. (see THE CHAIN BREAK, page 21) Fig. 11 Fig. 12 STAND TO THE LEFT OF SAW Thumb on underside of handlebar CAUTION: Do not touch the ground with the chain. Ensure safety clearance of 20 cm. (7-7/8 inch.) If an increasing oil pattern develops, the automatic oiler is operating fine. If there is no oil pattern, despite a full oil reservoir, see “Troubleshooting”. KICKBACK (Fig. 10a, 10b) Fig. 10a Fig. 10b Avoid Obstructions Kickback Path Clear The Work Area KICKBACK is the backward, upward or sudden forward motion of the guide bar occurring when the saw chain near the upper tip of the guide bar contacts any object such as a log or branch, or when the wood closes in and pinches chain in the cut. Contacting a foreign object in the wood can also result in loss of chain saw control. When kickback occurs the chainsaw reacts unpredictably and can cause severe injuries to the operator or bystanders. Particular attention must be given when sawing sideward, slanted or during length cuts, as the spiked bumper usually can not be applied. To avoid kickback: • Saw with guide bar at a flat angle. • Never work with a loose, widely stretched or the heavily worn out chain. • Ensure chain is sharpened correctly. • Never saw above shoulder height. • Never work with the tip of the guide bar. • Always hold the chain saw firmly with both hands. • Always use a low kickback chain. • Apply the metal gripping teeth for leverage. • Ensure correct chain tension. 22 Use the chain saw only with secure footing. Hold the chain saw at the right-hand side of your body. (See Figs. 11 and 12) The chain must be running at full speed before it makes contact with the wood. Use the metal gripping teeth to secure the saw onto the wood before starting to cut. Use the spiked bumper (9) as a leverage point while cutting. (See Fig. 13) Fig. 13 Spiked Bumper 9 23 OPERATION cont. OPERATION cont. GENERAL CUTTING cont. GENERAL CUTTING cont. Reset the gripping teeth at a low point when sawing thicker logs by pulling the chain saw slightly backwards until the gripping teeth release, and reposition at lower level to continue sawing. (See Fig. 13) CUTTING LOGS Observe the following safety instructions: • Do not remove the saw completely from the wood. • Do not force the chain while cutting, let the chain do the work, using the gripping teeth to apply minimal leverage pressure. • Do not operate the chain saw with arms fully extended or attempt to saw areas which are difficult to reach, or on a ladder. Never use the chain saw above shoulder height. (See Fig. 14) Fig. 14 Support logs so that the face sides at the cut do not close in against each other, which would result in the chain being jammed or pinched. (See Figs. 15 and 16) Fig. 15 Fig. 16 Y Z Z ! kg WARNING: Never use the chain saw above shoulder height. NOTE: Sawing is optimized when the chain speed remains steady during cutting. Beware when reaching the end of the cut. The weight of the saw may change unexpectedly as it cuts free from the wood. Y ! CAUTION: Position and set short logs safety prior to sawing. Saw only wood or wooden objects. When sawing, always take care to avoid hitting stones, nails, ect, as these could be thrown up or cause damage to the chain or serious injury to the operator or bystanders. Keep a running saw clear or wire fencing or the ground. Accidents can occur to the legs and feet. Use of the saw to thin out branches or bushes is not approved. Length cuts must be carried out with care, as leverage with the spiked bumper is not possible. Saw at a flat angle to avoid kickback. Always remove the saw from a wood cut while the saw is running. When working on a slope, operate above or to the side of the trunk or laying tree. Be careful not to trip over tree stumps, branches, roots, etc. NOTE: Do not attempt a pruning or limbing operation in a standing tree unless specifically trained to do so. NOTE: When cutting a limb that is under tension or compression, be alert for springback. 24 CUTTING WOOD UNDER TENSION (See Fig. 16) There is a high risk of accidents when sawing wood, branch or trees under tension. Be extremely careful. Leave saw jobs like these to professionals. When sawing logs supported on both ends, start the cut from above (Y) about 1/3 of the diameter into the log and then finish the cut (Z) from below, in order to avoid contact of the chain saw with the ground. When sawing logs supported on only one end, start the cut from below (Y) about 1/3 of the diameter into the log and finish the cut from above (Z) in order to avoid log splitting or jamming of the chain saw. 25 OPERATION cont. OPERATION cont. GENERAL CUTTING cont. GENERAL CUTTING cont. FELLING TREES (See Fig. 17) LIMBING A TREE (See Fig. 18) Always wear hard hat to protect head against falling branches. The chain saw can only be used to fell trees smaller in diameter than the length of the guide bar. Limbing is removing the branches from a fallen tree. When limbing leave larger lower limbs to support the log off the ground. Remove the small limbs in one cut as illustrated. Branches under tension should be cut from the bottom up to avoid binding the chain saw. 1. Secure work area (See 1, Fig. 17). Ensure no persons or animals are in the vicinity of the falling tree. Never attempt to free a jammed saw with the motor running. Use wooden wedges to free chain and guide bar. When cutting and felling operations are being performed by two or more persons, at the same time, the felling operations should be separated from the cutting operation by a distance of at least twice the height of the tree being felled. Trees should not be felled in a manner that would endanger any person, strike any utility line or cause any property damage. If the tree does make contact with any utility line, the company should be notified immediately. The chain saw operator should keep on the uphill side of the terrain as the tree is likely to roll or slide downhill after it is felled. 2. An escape path (See 2, Fig. 17) should be planned and cleared as necessary before cuts are started. The escape path should extend back and diagonally to the rear of the expected line of fall. 3. Before felling is started (See 3, Fig. 17), consider the natural lean of the tree, the location of larger branches and the wind direction to judge which way the tree will fall. Remove dirt, stones, loose bark, nails staples, and wire from the tree. Notching undercut: Make the notch (x-w) 1/3 the diameter of the tree, perpendicular to the direction of falls as make the lower horizontal notching cut first. This will help to avoid pinching either the saw chain or the guide bar when the second notch is being made. Fig. 17 3 X W 50mm Y Z 1 BUCKING A LOG (See Fig. 19) Fig. 19 Bucking is cutting a log into lengths. It is important to make sure your footing is firm and your weight is evenly distributed on both feet. When possible, the log should be raised and supported by the use of limbs, logs or chocks. Follow the simple directions for easy cutting. When the log is supported along its entire as illustrated, it is cut from the top (overbuck). 1 Felling back cut: Make the felling back cut (Y) 50mm at least 50 mm (2-Inches) higher than the 1 horizontal notching cut. Keep the felling back 2 2 cut parallel to the horizontal notching cut. Make the felling back cut so enough wood is left to act as a hinge. The hinge wood keeps the tree from twisting and falling in the wrong direction. Do not cut through the hinge. As the felling gets close to the hinge the tree should begin to fall. If there is any chance that the tree may not fall in desired direction or it may rock back and bind the saw chain, stop cutting before the felling back cut is complete and use wedges of wood, plastic, or aluminum to open the cut and drop the tree along the desired line of fall. When the tree begins to fall remove the chain saw from the cutting, stop the motor, put the chain saw down, and then use the retreat path planned. Be alert for overhead limbs falling and watch your footing. To complete the felling operation, drive a wedge (Z) into the horizontal cut. BEWARE of falling branches when the tree starts to move. 26 Fig. 18 When the log is supported on one end, as illustrated, cut 1/3 the diameter from the underside (underbuck). Then make the finished cut by overbucking to meet the first cut. (See Fig. 20) Fig. 20 2 1 1/3 2/3 27 OPERATION cont. MAINTENANCE GENERAL MAINTENANCE GENERAL CUTTING cont. BUCKING A LOG cont. When the log is supported on both ends, as illustrated, cut 1/3 the diameter from the top overbuck. Then make the finished cut by underbucking the lower 2/3 to meet the first cut. (See Fig. 21) Fig. 21 2 1 1/3 2/3 When bucking on a slope always stand on the uphill side of the log, as illustrated. ! WARNING: Before performing any work on the Chain Saw, disconnect the Chain Saw’s power plug from the extension cord and power source. NOTE: To ensure long and reliable service, carry out the following maintenance regularly and before each use: Regularly check for obvious defects such as loose, dislodged or damaged chain and guide bar, loose fixings and worn or damaged components. Inspect the switch and cord for damage. Check that covers and guards are undamaged and correctly fitted. ! WARNING: DO NOT use the Chain Saw if it has any broken parts. ALWAYS have damaged, missing, worn or broken parts replaced before using. When “cutting through”, to maintain complete control release the cutting pressure near the end of the cut without relaxing your grip on the chain saw handles. NOTE: WHEN SERVICING a tool, use only identical replacement parts. Use of unauthorized parts or failure to follow maintenance instructions may create a risk of electric shock or injury. Don’t let the chain contact the ground. After completing the cut, wait for the saw chain to stop before you move the chain saw. Fig. 22 Carry out necessary maintenance or repairs before using the chain saw. If the chain saw should happen to fail despite the care taken in manufacturing and testing, repair should be carried out by an authorized, qualified service dealer or repair center. Before returning, ensure all oil in the oil tank has been emptied. Replacing/Changing Chain And Guide Bar Fit the chain and guide bar as described in “Assembly and Tensioning Chain”, (See pages 16 and 17). The circular groove of the guide bar will wear particularly on the lower edge with time. When replacing the chain turn the chain bar 180° to allow even wear, thus extending chain bar life. Always stop the motor before moving from tree to tree. (See Fig. 22) Check Drive Sprocket. If it is worn out or damaged due to strain, have it exchanged by an authorized service dealer. If The Chain Bar Is Worn Out Or Damaged, take the chain tensioning catch off the bar by loosing the screw counter-clockwise. Then fit the tensioning catch into the new bar by tightening the screw clockwise. The catch protrude (1) must be fitted into the bar hole. (See Fig. 23) Sharpening Chain. Have your chain sharpened professionally at your approved service dealer or repair center or sharpen the chain yourself using the sharpening kit. Follow the sharpening instructions supplied with the sharpening kit. 28 29 1 Fig. 23 CLEANING / STORAGE SPECIFICATIONS Model 71-34120 GENERAL MAINTENANCE cont. • Clean the moulded plastic housing of the chain saw using a soft brush and clean cloth.
