Chain saw work is strenuous. If you have any condition that might be aggravated by strenuous work, check with your doctor before operating a chain saw. Carefully plan your sawing operation in advance. Do not start cutting until you have a clear work area, secure footing, and, if you are felling trees, a planned retreat path. 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 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. 16 NOTE: For chain saws, designed with the guide bar on the left side, the reference to "right hand" and "left hand" positioning is reserved. Do not operate the chainsaw with one hand! Serious injuries to the operator, assistants and others can result from operation with one hand. The chainsaw is designed for two-handed operation. Start work only after freeing the work area from unnecessary objects. Before starting the device, make sure that the chain is not in contact with anything.During saw transportation, the motor must be turned off with the bar and chain facing back. When carrying the chainsaw, always place the cover on the bar. WARNING: Always disconnect spark plug wire and place wire where it cannot contact spark plug to prevent accidental starting when setting up, transporting, adjusting or making repairs except carburetor adjustments. This chain saw for forest service is only designed for cutting wood. Because a chain saw is a high-speed wood-cutting tool, special safety precautions must be observed to reduce the risk of accidents. Careless or improper use of this tool can cause serious injury. Handle fuel with caution - Do not smoke while handling fuel or while operating the saw. - Eliminate all sources of sparks or flame in the areas where fuel is mixed or poured. There should be no smoking, open flames, or work that could cause sparks. Allow engine to cool before refueling. - Mix and pour fuel in an outdoor area on bare ground; store fuel in a cool, dry, well ventilated place; and use an approved, marked container for all fuel purposes. Wipe up all fuel spills before starting saw. - Move at least 10 feet(3 meters)from fueling site before starting engine. - Turn the engine off and let saw cool in a non-combustible area, not on dry leaves, straw, paper, etc. Slowly remove fuel cap and refuel unit. - Store the unit and fuel in an area where fuel vapors cannot reach sparks or open flames from water heaters, electric motors or switches, furnaces, 17 etc. Be especially careful when trimming bushes and seedlings, as their elastic branches can fall into a chain, hit or unbalance you. When cutting a branch that is exposed to external load, beware of the impact after removing the load. Before sawing, check the wood for foreign objects such as nails. Be sure to remove them before cutting. Use the device only for its intended purpose. The saw is intended for cutting wood only. Do not use the saw for other purposes not specified herein. For example cutting plastics, masonry, etc. Before work, clean and wipe the handles. Do not cut above shoulder level, bend over too much and touch the ground with a saw chain. When sawing boards and logs, it is necessary to use a reliable stand (framing). Do not let the other person hold the log while sawing and never hold the log with your foot. Do not work in low light conditions and on steep slopes. The saw should be guided in such a way that no part of the body is in the cutting plane (Fig.1). (Fig.1). 18 National regulation can restrict the use of the product. To avoid kickback WARNING: Avoid kickback which can result injury. 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 the saw chain in the cut. Contacting a foreign object in the wood can also result in loss of chain saw control. 1.Saw with guide bar at a flat angle. 2.Never work with a loose, widely stretched or heavily worn-out chain. 3.Ensure chain is sharpened correctly. 4.Never saw above shoulder height. 5.Never work with the tip of the guide bar. 6.Always hold the product firmly with both hands. 7.Always use a low kickback chain. 8.Apply the metal gripping teeth for leverage. 9.Ensure correct chain tension. 10.Do only cut with the engine at high speeds. 11.Do not let the nose of the guide bar contact a log, branch, or any other obstruction which could be hit while you are operating the product. 12.Follow manufacturer's sharpening and maintenance instructions for the saw chain. 13.Only use replacement guide bars and saw chains specified by the manufacturer or equivalent replacements. Never use chainsaw as a planer. Be careful! There is a danger of rebound when working with a chainsaw. A rebound causes loss of control of the chainsaw and can cause serious or even fatal injury. Bounce with rotation and bounce due to jamming represent the main danger when working with chain saws and are the main cause of most accidents. A rebound occurs when the front or top of the saw blade (especially the upper quarter) touches the tree or other hard objects, and also when the cut in the tree closes and wedges the chain. Frontal contact with the upper part of the saw blade can cause a lightning fast reaction, in which the tool bounces up and back to the operator. Jamming of the chain at the bottom of the guide bar pushes the chainsaw out of the operator. Jamming of the chain at the top of the guide bar 19 pushes the device back to the operator. Any of these effects results in loss of control of the saw and serious injury (Fig.2). (Fig.2) (Fig.2) Do not operate the chainsaw with the air filter removed or the air filter cover removed. Avoid the poisonous effects of toxic gases! Exhaust fumes contain carbon monoxide (CO) and other gases hazardous to health and life.Do not use the device indoors. If during work you have experienced symptoms of poisoning, you need to catch your breath in fresh air and seek medical help. When finished, drain the fuel mixture from the tank. WARNING! Do not empty the fuel mixture into the sewer or to the ground. It must be poured into special containers for fuel. It is necessary to observe not only the general safety requirements given in this section, but also the special instructions contained in other sections. Non-observance of safety instructions can create a danger to the environment, 20 damage the tool, and also entail dangerous consequences for human health and life. Failure to follow the safety instructions will void the warranty for damages. Clothing and personal protective equipment (PPE) 1. Secure long hair so that they are above the shoulder level. 2.

Assembly requirements Before you start up your chainsaw for the first time you must assemble the bar and chain, adjust the chain, fill the fuel tank with fuel and add oil to lubricate the chain. Warning! Do not START the chain saw until it is completely set up for use. Read this manual carefully before using the machine. Pay particular attention to 23 safety precautions. This manual is a reference and instruction manual and provides general information on the assembly, operation and maintenance of the chainsaw. Drive bar and saw chain assemble. WARNING! Always wear protective gloves when working with the chain. 1. Make sure that the device is turned off. Place the saw on a flat surface. 2. Move the chain brake shield to the operating position by pulling the lever toward you. Make sure the chain rotates around the bar (fig.4). 3. Unscrew the two nuts (A) securing the bar and chain guard. Remove the protective cover together with the chain brake shield (B) (fig.5). (fig.4). 24 (fig.5) 4.Install the bar so that the bar slot aligns with both bolts (C) (fig. 6). 5. Spread the chain in a circle with the cutting edges (D) aligned with the markings on the chain saw guard and guide bar (fig. 7). (fig. 6). 25 (fig. 7) 6.Run the chain behind the drive chain wheel (E). Check if the chain links are well positioned between the teeth of the chain wheel. 7. Insert the links into the bar groove (F) on the periphery (Fig. 8). (Fig. 8) 8. Rotate the chain to make sure the chain teeth are engaging the teeth of the chain wheel. 9. Replace the chain guard and chain brake shield so that the bolts fit into the holes provided and the chain tensioning pin fits into the lower hole in the bar (fig. 9). 26 (fig. 9) 10. Install both nuts, tighten them by hand, and then follow the instructions for adjusting the chain tension. When the chain has reached the correct tension, tighten the nuts completely. Chain tension adjustment WARNING! Always wear protective gloves when working with the chain. Proper chain tension is extremely important and should be checked both before starting and periodically during operation. Taking the time to adjust the chain will improve your performance and extend the life of your saw. WARNING! A new chain will sag quickly and require tensioning after 5 to 8 cuts. This is common with new chains and the tensioning interval increases over time. The cogwheel, tire, chain, and crankshaft will wear much faster if the chain is too loose or too tight. Look at fig. 10, which shows the correct tension for a cold chain (A), a warm chain (B), and a chain whose tension needs to be adjusted (C). 27 (fig. 10) Chain tension adjusting procedure 1. Loosen the tire nuts (protective cover with brake shield) and turn the adjusting screw (D) clockwise to tighten the chain. Turn the adjusting screw (D) counterclockwise to decrease chain tension. Make sure the chain is all the way around the bar (fig. 11). 2. After adjusting the chain, tighten the nuts securing the bar (protective cap together with the brake shield) firmly. The chain is considered properly tensioned if you can move it over the bar by hand with little effort. The chain should fit well on the underside of the saw blade and be pulled by hand away from the blade by about 2-4 mm. (fig. 11). 28 NOTE: If the chain has difficulty moving on the bar or stops, it is over tightened. Loosen the tension. Checking the chain brake Your chain saw has a chain brake that reduces the chance of injury if the saw bounces. The safety device is triggered when pressure is applied to the brake guard. When the operator's hand strikes the shield, the chain stops sharply. The chain brake has two positions: 1. The brake is off (the chain can move) when the brake shield is pulled back (A) (fig. 12). 2. 2. The brake is on (the chain cannot move) with the brake shield pointing forward (B). In this case, the chain should not move on the bar (fig. 12). (fig. 12) 29 (fig. 12) To check the chain brake: 1. Place the saw on a level surface and turn off the chain brake. The chain should not come into contact with anything. 2. Start the chainsaw by pressing the throttle lock key and the throttle key. 3. Press the chain brake switch. The chain should stop quickly. Release the throttle key. WARNING! The brake shield must be in good condition and must make a distinctive click when moving from one position to another. Do not use the unit if the brake shield cannot be moved to one of the positions or if the chain does not stop when the brake is applied. Take the unit to a service center for repair. Chain saw oil changing WARNING! Never use used oil! Waste oil is harmful to the environment and may result in damage. Chain saw oil should be used to lubricate the saw chain and bar. Use oil that contains additives to reduce friction and wear and to prevent resin build-up on the bar and chain. 30 WARNING! Before filling the oil tank, make sure that the chainsaw is turned off. To fill the oil tank: 1. Be sure to clean the surface around the oil tank cap to prevent dirt from getting inside. 2. Unscrew the oil tank cap and pour in the chain saw oil (260 ml tank capacity). 3. Screw the oil tank cap back on. 4. Before you start, check the oil supply: switch on the chainsaw and hold it over suitable bedding. If it is sufficiently lubricated, a light trail of dripping oil will form (fig. 13). (fig. 13) WARNING! Always check the oil level. Do not operate the chain saw if there is insufficient oil to lubricate the chain. Proper lubrication is essential to reduce chain and bar friction. Operating a chain saw with insufficient lubrication reduces performance and service life and causes fast chain and bar wear due to overheating.This chainsaw is equipped with an automatic lubrication system that provides the necessary amount of lubrication to the bar and chain. As the engine speed increases so does the oil supply to the bar. Chainsaw fuel mix For best results use standard quality AI-92 gasoline without additives mixed with 31 special oil for 2-stroke engines in the proportion indicated on the oil package. The recommended mixing ratio is 1:40, unless this differs from the oil manufacturer's recommendation. Mix fuel and 2-stroke oil in a special container until a homogeneous mixture is obtained. WARNING! Do not fill your chainsaw with pure gasoline. This will cause the engine to malfunction and will void the manufacturer's warranty on the product. It is not recommended to use a fuel mixture that has been stored for more than 30 days. OPERATING PROCEDURE Before starting work, check the work area and remove foreign objects that could cause injury or damage the equipment. Operate the tool only during daylight hours or in good lighting conditions. Be careful and use common sense at all times when operating the saw. If an abnormal situation occurs, shut off the chainsaw immediately and contact an authorized service center. Starting the engine 1. Make good pillar and lay the chainsaw on the ground so that the chain does not touch anything. 2. Hold the front handle with one hand and take the chainsaw to the ground. Hold the rear handle by stepping on it. 3. Set the ignition switch to the "on" position. 4. Pull the air damper lever toward you until it locks, the air damper will close. 5. Slowly pull the starter grip until you feel resistance, then pull the cable with a steady and steady movement to a distance of no more than 50-60 cm. Repeat the procedure several times until the engine starts. 6. Press the throttle lock key and the throttle key, the carburettor air damper will open automatically, the damper lever will return to its original position. WARNING! Do not allow the cable to be pulled all the way out before the 32 starter reel has stopped. This will cause the starter motor to break and is not covered by the warranty. Stop the engine 1. Release the throttle lock key and throttle key to allow the engine to idle. 2. To stop the engine, move the switch to the "off" position. NOTE: To stop the engine in an emergency, engage the chain brake and move the switch to the "off" position. Clipping Small trees up to 15 cm diameter are usually cut off with a single cut. On larger trees, a pre-cut must be made. The notch determines the direction in which the tree will fall. WARNING! Mark out your escape path (A) in advance and clear it of possible obstacles before you start cutting. The escape path must be in the direction opposite to the direction in which the tree is expected to fall (B) (fig. 14). (fig. 14) WARNING! When felling a tree is on a slope, the operator must stand higher on the slope as the felling tree may roll down. 33 NOTE: The direction of fell is determined by the notch. Before making the cuts, assess the distribution of the large branches, the center of gravity of the crown, and the natural slope of the tree to determine the direction of tree felling. WARNING! Do not fell a tree in high or changing winds and if there is a risk of property damage. Do not fell a tree if there is a risk of damage to wires. Coordinate felling with utilities and professionals. Felling a tree Usually felling a tree consists of two basic operations: notching (C) and making the final cut (D). Start the notching (C) on the side of the tree that is in the intended direction of fall (E). Make sure that the notch does not go too deep into the trunk. The notch (C) must be made so that a sufficiently thick and strong part of the trunk (F) is left uncut. The notch must be wide enough to completely guide the falling of the tree when felling. Warning! Do not walk in front of a tree that has already been notched. The final cut (D) is made on the back side of the tree 3-5 cm above the horizontal base of the notch (C) (fig. 15). (fig. 15) Never cut the trunk all the way down. Always leave an adequately thick and strong part of the trunk (F) uncut. This uncut part prevents the tree from falling prematurely and guides it when it falls. If you cut the trunk all the way down, you will lose control over the direction of the fall. Place a wedge or lever in the cut before the tree becomes unstable and begins to move. This way, you will prevent the bar from jamming in the cut if you have misjudged the direction of fall. Before you fell the tree, make sure that no one is in 34 the fall area of the tree. WARNING! Before making the final cut, always make sure there are no animals or any objects in the work area. Final Cut Use wooden or plastic wedges (A) to prevent the bar or chain (B) from jamming in the cut. The wedges also control the felling (fig. 16). (fig. 16) When the diameter of the trunk is greater than the length of the bar, two cuts are made, as shown in (fig.17). (fig.17) WARNING! During the final cut, if the chainsaw approaches the uncut part of the trunk, the tree will begin to fall. 35 When the tree begins to fall, remove the chainsaw from the cut, stop the engine, place the chainsaw on the ground, and leave the area of the intended escape route. Perform all actions promptly, without delay. Branch pruning WARNING! Do not trim branches while standing on the trunk. It may result in serious injury. Branches are cut from the fallen tree. Do not cut branches that support the trunk and keep it from rolling away (A) until you have cut the trunk (fig.18). Branches subject to external loads should be cut from the bottom up to prevent the chainsaw from jamming. Crosscut sawing The sawing is done across the wood fibers. When working on a slope, make sure that you are in a stable position and that you are standing on the higher side of the slope in relation to the trunk. Make sure that the trunk rests on its supports and that the end to be sawed off is not on the ground. Make sure that the chain does not run into the ground, as this will cause rapid wear on the chain. 36 (fig.18) For cross-cutting sawing the toothed stop 1 (fig. 19) must be set on the log to be sawed off. 1. If the log is supported along its entire length, drive the chain saw from top to bottom while making sure that the chain does not run into the ground (fig. 20). 2. When the trunk is at one end of its support, first cut down to about 1/3 of the diameter of the trunk to prevent splitting. Then finish the cut at the top so that it coincides with the first cut, avoiding jamming (fig. 21). (fig. 20) 37 (fig. 21) 3. In the case where the trunk is supported at both ends, first cut from the top 1/3 of the diameter of the trunk to avoid splitting. Then finish the cut from below so that it coincides with the first cut, avoiding jamming (fig. 22). For sawing into pieces, it is best to prop the trunk up with goaders. If this is not possible, the trunk should be lifted and placed on the logs. Make sure that the trunk is securely fastened.For personal safety and to make sawing easier, observe the correct body position (fig. 23): 1. Hold the saw firmly with both hands to the right of your body. 2. Keep your left arm as straight as possible. 3. Keep your balance by leaning on both feet. TECHNICAL SERVICE WARNING!

Dust and particulate matter can enter the engine, dust and solid particles may get into the engine and cause damage and malfunction. Keep the air filter clean!Clean the air filter: 1. Remove the air filter cover 1 (Fig. 24) by unfastening the latches 3. Use a screwdriver with a spark plug wrench 2. 2. Unscrew nut 4 (Fig. 25) and remove the filter 5. 3. Clean the air filter by tapping it lightly on a hard surface. Blow out the inside with compressed air (not more than 2 bar). WARNING! Do not wash the filter with water. 39 (Fig.24) (Fig.25) Install the air filter. Install the engine/air filter cover. Check that the cover is correctly installed, the cover is seated properly. Snap the catches into place. Spark plug For effective saw working keep the spark plug clean and free of carbon deposits. The distance between the electrodes must be correctly adjusted. 1. Make sure that the saw is off. 2. Clean the surface near the spark plug. 3. Disconnect the high voltage cable from spark plug 1 (Fig. 26). 4. Unscrew the spark plug 2 using the special spark plug wrench. DO NOT USE ANY OTHER TOOL. The electrodes of the spark plug should be light brown. 5. Replace the spark plug if the ceramic insulator is chipped or if the electrodes are burnt or soiled. 6. Clean the electrodes to metal with fine sandpaper, check and adjust the gap. 7. Check the gap between the ground electrode and the center electrode, using a 40 special probe. If necessary set the gap to 0.7-0.8 mm (Fig. 27). 8. Install the spark plug into the engine and tighten securely. Insufficient tightening of the spark plug can cause it to overheat and damage the engine. 9. Connect it to the high-voltage wire. Carburetor adjustment The carburetor is factory set for optimum performance. If adjustments are necessary, contact your nearest authorized service center. Preservation of the chain saw When storing the chainsaw for more than 30 days, you must preserve it. If preservation instructions are not followed, the fuel remaining in the carburetor will evaporate, leaving a viscous, jelly-like residue. This will cause engine start-up problems and costly repairs. WARNING! Do not store the chainsaw for more than 30 days unless the following measures have been taken: 1. Carefully open the fuel filler cap so that any excess pressure that may be present in the fuel tank is slowly released. Drain any remaining fuel. 2. Start the engine and run it until it stops to allow the carburetor to evaporate. 41 3. Allow the engine to cool (about 5 minutes). 4. Use a spark plug wrench to remove the spark plug. 5. Add 1 teaspoon of pure 2-stroke oil to the spark plug hole. Pull the starter cord slowly several times to coat the internal components with oil. Reinsert the spark plug. NOTE: Store the chainsaw in a dry place away from possible sources of fire such as stoves, gas heaters, etc. Preparing the machine for use after preservation 1. Remove the spark plug. 2. Retrieve the starter cord with a forceful pull to bleed excess oil from the fuel tank. 3. Clean and adjust the spark plug gap or insert a new spark plug with the proper gap. 4. Prepare the chainsaw for operation. 5. Fill the tank with a suitable fuel mix of gasoline and oil. Cleaning the tool WARNING! Do not use water or other liquids for cleaning! Be careful when cleaning the tool. Always wear protective gloves. Turn off the machine. Wait approximately 10-15 minutes for the engine to cool completely. Wipe all surfaces and vents with a dry cloth or rag and use a special brush if necessary. To ensure proper operation of the oil pump, periodically clean the oil groove and the oil inlet in the guide bar of the saw. Bar maintenance The toothed wheel on top of the guide bar should be lubricated regularly. Proper care of the bar, as described in this section, is essential to the quality of your chain saw.To lubricate the chain sprocket, we recommend the use of a grease gun (not included). 42 To maintain the bar chain wheel: Turn off tool, allow bar and chain to cool. Clean the toothed chain wheel. Place the needle-shaped nozzle of the syringe in the grease hole and inject grease until it appears on the outside edge of the chain bar wheel (fig. 28). Move the chain by hand. Repeat the above lubrication procedure until the entire chain bar wheel is lubricated. The bar should be rotated every 8 hours of operation for even wear. Keep the tire groove and lubrication hole clean with the cleaning tool (not supplied) (fig. 29). (fig. 28) (fig. 29) Regularly inspect the rails for wear, remove burr if necessary, and clean the rails at right angles with a flat file (fig. 30). Chain Maintenance First the shortest saw tooth is sharpened. Its length is the target length for 43 sharpening all other teeth of the saw chain. Guide the file as shown in the illustration. The file holder makes it easier to guide the file during sharpening and has a marking for the correct 30° sharpening angle (align the marking with the direction of the saw chain). It limits the penetration depth (4/5 of the file diameter) (fig. 30). (fig. 30) (fig. 31) Even a slight excess of the depth gauge tooth should be ground down with a special flat file. The depth gauge should be rounded at the front. At the end of the sharpening process, the height of the depth stop should be checked with a chain gauge (fig. 31). 44 POSSIBLE MALFUNCTIONS AND TROUBLESHOOTING METHODS Problem Possible reason Corrective action/s Violation of start-up procedures.
