General power tool safety warnings WARNING: Read all safety warnings, instructions, illustrations and specifications provided with this power tool. Failure to follow all instructions listed below may result in electric shock, fire and/or serious injury. Save all warnings and instructions for future reference. The term "power tool" in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool. Work area safety 1. Keep work area clean and well lit. Cluttered or dark areas invite accidents. 2. Do not operate power tools in explosive atmo- spheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes. 3. Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control. Electrical safety 1. Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock. 3 ENGLISH 2. Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded. 3. Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock. 9. Always wear protective goggles to protect your eyes from injury when using power tools. The goggles must comply with ANSI Z87.1 in the USA, EN 166 in Europe, or AS/NZS 1336 in Australia/New Zealand. In Australia/New Zealand, it is legally required to wear a face shield to protect your face, too. 4. Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock. 5. When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock. 6. If operating a power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply. Use of an RCD reduces the risk of electric shock. 7. Power tools can produce electromagnetic fields (EMF) that are not harmful to the user. However, users of pacemakers and other similar medical devices should contact the maker of their device and/or doctor for advice before operating this power tool. Personal safety 1. Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury. 2. Use personal protective equipment. Always wear eye protection. Protective equipment such as a dust mask, non-skid safety shoes, hard hat or hearing protection used for appropriate conditions will reduce personal injuries. 3. Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or energising power tools that have the switch on invites accidents. 4. Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury. 5. Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations. 6. Dress properly. Do not wear loose clothing or jewellery. Keep your hair and clothing away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts. 7. If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can reduce dust-related hazards. 8. Do not let familiarity gained from frequent use of tools allow you to become complacent and ignore tool safety principles. A careless action can cause severe injury within a fraction of a second. It is an employer's responsibility to enforce the use of appropriate safety protective equipments by the tool operators and by other persons in the immediate working area. Power tool use and care 1. Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed. 2. Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired. 3. Disconnect the plug from the power source and/or remove the battery pack, if detachable, from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally. 4. Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users. 5. Maintain power tools and accessories. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tool's operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools. 6. Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control. 7. Use the power tool, accessories and tool bits etc. in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation. 8. Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles and grasping surfaces do not allow for safe handling and control of the tool in unexpected situations. 4 ENGLISH 9. When using the tool, do not wear cloth work gloves which may be entangled. The entanglement of cloth work gloves in the moving parts may result in personal injury. Battery tool use and care 1. Recharge only with the charger specified by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack. 2. Use power tools only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire. 3. When battery pack is not in use, keep it away from other metal objects, like paper clips, coins, keys, nails, screws or other small metal objects, that can make a connection from one terminal to another. Shorting the battery terminals together may cause burns or a fire. 4. Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns. 5. Do not use a battery pack or tool that is damaged or modified. Damaged or modified batteries may exhibit unpredictable behaviour resulting in fire, explosion or risk of injury. 6. Do not expose a battery pack or tool to fire or excessive temperature. Exposure to fire or temperature above 130 °C may cause explosion. 7. Follow all charging instructions and do not charge the battery pack or tool outside the temperature range specified in the instructions. Charging improperly or at temperatures outside the specified range may damage the battery and increase the risk of fire. Service 1. Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained. 2. Never service damaged battery packs. Service of battery packs should only be performed by the manufacturer or authorized service providers. 3. Follow instruction for lubricating and changing accessories. General chain saw safety warnings 1. Keep all parts of the body away from the saw chain when the chain saw is operating. Before you start the chain saw, make sure the saw chain is not contacting anything. A moment of inattention while operating chain saws may cause entanglement of your clothing or body with the saw chain. 2. Always hold the chain saw with your right hand on the rear handle and your left hand on the front handle. Holding the chain saw with a reversed hand configuration increases the risk of personal injury and should never be done. 3. Hold the chain saw by insulated gripping surfaces only, because the saw chain may contact hidden wiring. Saw chains contacting a "live" wire may make exposed metal parts of the chain saw "live" and could give the operator an electric shock. 4. Wear eye protection. Further protective equipment for hearing, head, hands, legs and feet is recommended. Adequate protective equipment will reduce personal injury from flying debris or accidental contact with the saw chain. 5. Do not operate a chain saw in a tree, on a ladder, from a rooftop, or any unstable support. Operation of a chain saw in this manner could result in serious personal injury. 6. Always keep proper footing and operate the chain saw only when standing on fixed, secure and level surface. Slippery or unstable surfaces may cause a loss of balance or control of the chain saw. 7. When cutting a limb that is under tension, be alert for spring back. When the tension in the wood fibres is released, the spring loaded limb may strike the operator and/or throw the chain saw out of control. 8. Use extreme caution when cutting brush and saplings. The slender material may catch the saw chain and be whipped toward you or pull you off balance. 9. Carry the chain saw by the front handle with the chain saw switched off and away from your body. When transporting or storing the chain saw, always fit the guide bar cover. Proper handling of the chain saw will reduce the likelihood of accidental contact with the moving saw chain. 10. Follow instructions for lubricating, chain tensioning and changing the bar and chain. Improperly tensioned or lubricated chain may either break or increase the chance for kickback. 11. Cut wood only. Do not use chain saw for purposes not intended. For example: do not use chain saw for cutting metal, plastic, masonry or non-wood building materials. Use of the chain saw for operations different than intended could result in a hazardous situation. 12. Do not attempt to fell a tree until you have an understanding of the risks and how to avoid them. Serious injury could occur to the operator or bystanders while felling a tree. 13. 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 chain saw misuse and/or incorrect operating procedures or conditions and can be avoided by taking proper precautions as given below: 5 ENGLISH · 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. Fig.1 · 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. · Only use replacement guide bars and saw chains specified by the manufacturer. Incorrect replacement guide bars and saw chains may cause chain breakage and/or kickback. · Follow the manufacturer's sharpening and maintenance instructions for the saw chain. Decreasing the depth gauge height can lead to increased kickback. 14. Follow all instructions when clearing jammed material, storing or servicing the chain saw. Make sure the switch is off and the battery pack is removed. Unexpected actuation of the chain saw while clearing jammed material or servicing may result in serious personal injury. Additional Safety Instructions Personal protective equipment 1. Clothing must be close-fitting, but must not obstruct mobility. 2. Wear the following protective clothing during work: · A tested safety helmet, if a hazard is pre- sented by falling branches or similar; · A face mask or goggles; · Suitable ear protection (ear muffs, custom or mouldable ear plugs). Octave brand analysis upon request. · Firm leather safety gloves; · Long trousers manufactured from strong fabric; · Protective dungarees of cut-resistant fabric; · Safety shoes or boots with non-slip soles, steel toes, and cut-resistant fabric lining; · A breathing mask, when carrying out work which produces dust (e.g. sawing dry wood). Operation 1. Before starting work, check that the chain saw is in proper working order and that its condition complies with the safety regulations. Check in particular that: · The chain brake is working properly; · The run-down brake is working properly; · The bar and the sprocket cover are fitted correctly; · The chain has been sharpened and tensioned in accordance with the regulations. 2. Do not start the chain saw with the chain cover being installed on it. Starting the chain saw with the chain cover being installed on it may cause the chain cover to thrown out forward resulting in personal injury and damage to objects around the operator.

Check the amount of remaining oil in the oil tank periodically through the oil inspection window. 1 2 Fig.20 1. Oil tank cap 2. Oil inspection window To fill the oil, perform the following steps: 1. Clean the area around the oil tank cap thoroughly to prevent any dirt from entering the oil tank. 2. Lay the chain saw on its side and remove the oil tank cap. 3. Fill the oil tank with the oil. The proper amount of oil is 150 ml. 4. Screw the oil tank cap firmly back in place. 5. Wipe away any spilt chain oil carefully. NOTE: If it is difficult to remove the oil tank cap, insert the slotted screwdriver into the slot of the oil tank cap, and then remove the oil tank cap by turning it counterclockwise. Working with the chain saw CAUTION: The first time user should, as a minimum practice, do cutting logs on a saw-horse or cradle. CAUTION: When sawing precut timber, use a safe support (saw horse or cradle). Do not steady the workpiece with your foot, and do not allow anyone else to hold or steady it. CAUTION: Secure round pieces against rotation. CAUTION: Keep all parts of the body away from the saw chain when the motor is operating. CAUTION: Hold the chain saw firmly with both hands when the motor is running. CAUTION: Do not overreach. Keep proper footing and balance at all times. NOTICE: Never toss or drop the tool. NOTICE: Do not cover the vents of the tool. Bring the bottom edge of the chain saw body into contact with the branch to be cut before switching on. Otherwise it may cause the guide bar to wobble, resulting in injury to operator. Saw the wood to be cut by just moving it down by using the weight of the chain saw. 2 1 Fig.21 1. Slot 2. Slotted screwdriver After refilling, hold the chain saw away from the tree. Start it and wait until lubrication on saw chain is adequate. Fig.23 If you cannot cut the timber right through with a single stroke: Apply light pressure to the handle and continue sawing and draw the chain saw back a little; then apply the spike bumper a little lower and finish the cut by raising the handle. Fig.22 Fig.24 14 ENGLISH Bucking 1. Rest the bottom edge of the chain saw body on the wood to be cut. Fig.25 2. With the saw chain running, saw into the wood while using the rear handle to raise the saw and the front one to guide it. Use the spike bumper as a pivot. 3. Continue the cut by applying slight pressure to the front handle, easing the saw back slightly. Move the spike bumper further down the timber and raise the front handle again. NOTICE: When making several cuts, switch the chain saw off between cuts. CAUTION: If the upper edge of the bar is used for cutting, the chain saw may be deflected in your direction if the chain becomes trapped. For this reason, cut with the lower edge, so that the saw will be deflected away from your body. Limbing CAUTION: Limbing may only be performed by trained persons. A hazard is presented by the risk of kickback. When limbing, support the chain saw on the trunk if possible. Do not cut with the tip of the bar, as this presents a risk of kickback. Pay particular attention to branches under tension. Do not cut unsupported branches from below. Do not stand on the felled trunk when limbing. Burrowing and parallel-to-grain cuts CAUTION: Burrowing and parallel-to-grain cuts may only be carried out by persons with special training. The possibility of kickback presents a risk of injury. Perform parallel-to-grain cuts at as shallow an angle as possible. Take an extra caution when carrying out the cut as the spike bumper cannot be used. Fig.28 Felling CAUTION: Felling work may only be performed by trained persons. The work is hazardous. Observe local regulations if you wish to fell a tree. 45 o Fig.26 When you cut a wood under tension, cut the pressured side (A) first. Then make the final cut from the tensioned side (B). This prevents the bar from becoming trapped. A 2 1/2 45 o 1 Fig.27 B B A Fig.29 1. Felling area -- Before starting felling work, ensure that: · Only persons involved in the felling operation are in the vicinity; · Any person involved has an unhindered path of retreat through a range of approximately 45° either side of the felling axis. Consider the additional risk of tripping over electrical cables; 15 ENGLISH · The base of the trunk is free of foreign objects, roots and ranches; · No persons or objects are present over a distance of 2 1/2 tree lengths in the direction in which the tree will fall. -- Consider the following with respect to each tree: · Direction of lean; · Loose or dry branches; · Height of the tree; · Natural overhang; · Whether or not the tree is rotten. -- Consider the wind speed and direction. Do not carry out felling work if the wind is gusting strongly. -- Trimming of root swellings: Begin with the largest swellings. Make the vertical cut first, then the horizontal cut. -- Stand to the side of the falling tree. Keep an area clear to the rear of the falling tree up to an angle of 45° either side of the tree axis (refer to the "felling area" figure). Pay attention to falling branches. -- An escape path 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 as illustrated in figure. 1 2 3 3 2 Fig.30 1. Felling direction 2. Danger zone 3. Escape route When felling trees, follow the procedures below: 1. Cut a scarf as close to the ground as possible. First make the horizontal cut to a depth of 1/5 -1/3 of the trunk diameter. Do not make the scarf too large. Then make the diagonal cut. 2. Make the back cut a little higher than the base cut of the scarf. The back cut must be exactly horizontal. Leave approximately 1/10 of the trunk diameter between the back cut and the scarf. The wood fibers in the uncut trunk portion act as a hinge. Insert wedges into the back cut in time. Fig.32 WARNING: Do not cut right through the fibers under any circumstances. The tree will otherwise fall unchecked. NOTICE: Only plastic or aluminum wedges may be used to keep the back cut open. The use of iron wedges is prohibited. Carrying tool Before carrying the tool, always apply the chain brake and remove the battery cartridge from the tool. Then attach the guide bar cover. Also cover the battery cartridge with the battery cover. 1 2 Fig.33 1. Guide bar cover 2. Battery cover Fig.31 NOTE: The scarf determines the direction in which the tree will fall, and guides it. It is made on the side towards which the tree is to fall. 16 ENGLISH MAINTENANCE CAUTION: Always be sure that the tool is switched off and the battery cartridge is removed before attempting to perform inspection or maintenance. CAUTION: Always wear gloves when performing any inspection or maintenance. NOTICE: Never use gasoline, benzine, thinner, alcohol or the like. Discoloration, deformation or cracks may result. To maintain product SAFETY and RELIABILITY, repairs, any other maintenance or adjustment should be performed by Makita Authorized or Factory Service Centers, always using Makita replacement parts. Sharpening the saw chain Sharpen the saw chain when: · Mealy sawdust is produced when damp wood is cut; · The chain penetrates the wood with difficulty, even when heavy pressure is applied; · The cutting edge is obviously damaged; · The saw pulls to the left or right in the wood. (caused by uneven sharpening of the saw chain or damage to one side only) Sharpen the saw chain frequently but a little each time. Two or three strokes with a file are usually sufficient for routine resharpening. When the saw chain has been resharpened several times, have it sharpened in our authorized service center. Sharpening criteria: WARNING: An excessive distance between the cutting edge and depth gauge increases the risk of kickback. 2 1 2 1 -- The chip thickness is determined by the distance between the depth gauge (round nose) and the cutting edge. -- The best cutting results are obtained with following distance between cutting edge and depth gauge. · Chain blade 90PX : 0.65 mm · Chain blade 91PX : 0.65 mm 30 30 55 55 Fig.35 -- The sharpening angle of 30° must be the same on all cutters. Different cutter angles cause the chain to run roughly and unevenly, accelerate wear, and lead to chain breaks. -- Use a suitable round file so that the proper sharpening angle is kept against the teeth. · Chain blade 90PX : 55° · Chain blade 91PX : 55° File and file guiding -- Use a special round file (optional accessory) for saw chains to sharpen the chain. Normal round files are not suitable. -- Diameter of the round file for each saw chain is as follows: · Chain blade 90PX : 4.5 mm · Chain blade 91PX : 4.0 mm -- The file should only engage the cutter on the forward stroke. Lift the file off the cutter on the return stroke. -- Sharpen the shortest cutter first. Then the length of this shortest cutter becomes the standard for all other cutters on the saw chain. -- Guide the file as shown in the figure. 3 1 Fig.34 1. Cutter length 2. Distance between cutting edge and depth gauge 3. Minimum cutter length (3 mm) -- All cutter length must be equal. Different cutter lengths prevent the saw chain from running smoothly and may cause the saw chain to break. -- Do not sharpen the chain when the cutter length has reached 3 mm or shorter. The chain must be replaced with new one. 1 2 Fig.36 1. File 2. Saw chain 17 ENGLISH -- The file can be guided more easily if a file holder (optional accessory) is employed. The file holder has markings for the correct sharpening angle of 30° (align the markings parallel to the saw chain) and limits the depth of penetration (to 4/5 of the file diameter). 1 Cleaning the sprocket cover Chips and saw dust will accumulate inside of the sprocket cover. Remove the sprocket cover and saw chain from the tool then clean the chips and saw dust. 30 1/5 Fig.37 1. File holder -- After sharpening the chain, check the height of the depth gauge using the chain gauge tool (optional accessory). Fig.40 Cleaning the oil discharge hole Small dust or particles may be built up in the oil discharge hole during operation. These dust or particles may impair the oil to flow and cause an insufficient lubrication on the whole saw chain. When a poor chain oil delivery occurs at the top of guide bar, clean the oil discharge hole as follows. 1. Remove the sprocket cover and saw chain from the tool. 2. Remove the small dust or particles using a slotted screwdriver or the like. Fig.38 -- Remove any projecting material, however small, with a special flat file (optional accessory). -- Round off the front of the depth gauge again. Cleaning the guide bar Chips and sawdust will build up in the guide bar groove. They may clog the bar groove and impair the oil flow. Clean out the chips and sawdust every time when you sharpen or replace the saw chain. 1 Fig.41 2 1. Slotted screwdriver 2. Oil discharge hole 3. Insert the battery cartridge into the tool. Pull the switch trigger to flow built-up dust or particles off the oil discharge hole by discharging chain oil. 4. Remove the battery cartridge from the tool. Reinstall the sprocket cover and saw chain on the tool. Fig.39 18 ENGLISH Replacing the sprocket CAUTION: A worn sprocket will damage a new saw chain. Have the sprocket replaced in this case. Before fitting a new saw chain, check the condition of the sprocket. 2 1 Fig.42 1. Sprocket 2. Areas to be worn out Always fit a new locking ring when replacing the sprocket. Fig.43 1 2 1.
