5EN3. Installing Guide Bar and Saw Chain A standard saw unit package contains the items as illustrated. Open the box and install the guide bar and the saw chain on the power unit as follows: The saw chain has very sharp edges. Use thick protective gloves for safety. 1. Pull the guard towards the front handle to check that the chain brake is not engaged. 2. Loosen the nuts and remove the chain cover. 3. Gear the chain to the sprocket and, while fit- ting the saw chain around the guide bar, mount the guide bar to the power unit. Adjust the position of chain tensioner nut. !WARNING! Pay attention to the correct direction of the saw chain. 4. Fit the chain cover to the power unit and fas- ten the nuts to finger tightness. 5. While holding up the tip of the bar, adjust the chain tension by turning the tensioner screw until the tie straps just touch the bottom side of the bar rail. 6. Tighten the nuts securely with the bar tip held up (12 ~ 15 Nm). Then check the chain for smooth rotation and proper tension while moving it by hand. If necessary, readjust with the chain cover loose. 7. Tighten the tensioner screw. A new chain will expand its length in the beginning of use. Check and read- just the tension frequently as a loose chain can easily derail or cause rapid wear of itself and the guide bar. NOTE NOTE 3.

6MM6EN4. Fuel and Chain Oil • FUEL Gasoline is very flamma- ble. Avoid smoking or bringing any flame or sparks near fuel. Make sure to stop the engine and allow it cool before refueling the unit. Select outdoor bare ground for fueling and move at least 3 m (10 ft) away from the fuel- ing point before starting the engine. •The engines are lubricated by oil specially for- mulated for air-cooled 2-cycle gasoline engine use. Use an anti-oxidant added quality oil expressly labeled for air-cooled 2-cycle engine use (JASO FC GRADE OIL or ISO EGC GRADE). •Do not use BIA or TCW (2-stroke water-cool- ing type) mixed oil. •RECOMMENDED MIXING RATIO GASO- LINE 50: OIL 1 •Exhaust emission are controlled by the funda- mental engine parameters and components (eq., carburation, ignition timing and port tim- ing) without addition of any major hardware or the introduction of an inert material during combustion. •These engines are certified to operate on unleaded gasoline. •Make sure to use gasoline with a minimum octane number of 89RON (USA/Canada: 87AL). •If you use a gasoline of a lower octane value !WARNING! than prescribed, there is a danger that the engine temperature may rise and an engine problem such as piston seizing may conse- quently occur. •Unleaded gasoline is recommended to reduce the contamination of the air for the sake of your health and the environment. •Poor quality gasolines or oils may damage sealing rings, fuel lines or fuel tank of the engine. •HOW TO MIX FUEL Pay attention to agitation. 1. Measure out the quantities of gasoline and oil to be mixed. 2.Put some of the gasoline into a clean, approved fuel container. 3. Pour in all of the oil and agitate well. 4. Pour in the rest of gasoline and agitate again for at least one minute. As some oils may be difficult to agitate depending on oil ingredi- ents, sufficient agitation is necessary for the engine to last long. Be careful that, if the agi- tation is insufficient, there is an increased danger of early piston seizing due to abnor- mally lean mixture. 5. Put a clear indication on the outside of the container to avoid mixing up with gasoline or other containers. 6. Indicate the contents on outside of container for easy identification. •FUELING THE UNIT 1. Untwist and remove the fuel cap. Rest the cap on a dustless place.. 2. Put fuel into the fuel tank to 80% of the full capacity. 3. Fasten the fuel cap securely and wipe up any fuel spillage around the unit. !WARNING! 4. Fuel and Chain Oil
7EN4. Fuel and Chain Oil 1. Select flat and bare ground for fueling. 2. Move at least 10 feet (3 meters) away from the fueling point before starting the engine. 3. Stop the engine before refueling the unit. At that time, be sure to sufficiently agitate the mixed gasoline in the container. •FOR YOUR ENGINE LIFE, AVOID: 1. FUEL WITH NO OIL (RAW GASOLINE) – It will cause severe damage to the internal engine parts very quickly. 2. GASOHOL – It can cause deterioration of rubber and/or plastic parts and disruption of engine lubrication. 3. OIL FOR 4-CYCLE ENGINE USE – It can cause spark plug fouling, exhaust port block- ing, or piston ring sticking. 4. Mixed fuels which have been left unused for a period of one monthor more may clog the carburetor and result in the engine failing to operate properly. 5. In the case of storing the product for a long period of time, clean the fuel tank after ren- dering it empty. Next, activate the engine and empty the carburetor of the composite fuel. 6. In the case of scrapping the used mixed oil container, scrap it only at an authorized repository site. Moreover, normal wear and change in product with no functional influence are not covered by the warranty. Also, be careful that, if the usage in the instruction manual is not observed as to the mixed gasoline, etc. described therein, it may not be covered by the warranty. •CHAIN OIL Only use special oil for chain saws or adhesive oil for chain saws. Do not use oil containing impurities so as not to block the oil filter and to prevent irreparable damage to the oil pump. The special oil for lubricating the chain is biodegradable. Use of a mineral oil or engine oil causes serious damage to the envi- ronment. IMPORTANT IMPORTANT NOTE !WARNING!It is essential that you use good quality oil to lubricate the cutting parts effectively. Used or poor quality oil does not guarantee good lubri- cation and reduces the duration of the chain and bar. It is always worth topping up the oil tank com- pletely (using a funnel) every time you refuel. Since the oil tank capacity is enough to guaran- tee that the fuel runs out first, you will avoid the risk of operating the machine without lubricant.
8MM8EN5. Operating the Engine It is very dangerous to run a chainsaw that mounts broken parts or lacks any parts. Before starting engine, make sure that all the parts including bar and chain are installed properly. •STARTING THE ENGINE 1. Fill fuel and chain oil tanks respectively, and tighten the caps securely. 2. Set the switch to “I” position. 3. While holding the throttle lever together with the trigger safety, push in the side latch and release the throttle lever to leave it at the starting position. !WARNING!When restarting immediately after stopping the engine, set the Choke knob in the first-stage position (choke open and throttle lever in the starting position). Once the choke knob has been pulled out, it will not return to the operating position even if you press down on it with your finger. When you wish to return the choke knob to the operating position, pull out the throttle lever instead. 4. If your machine has aprimer (3), press it 3- 4 times to aid starting. 5. While holding the saw unit securely on the ground, pull the starter rope vigorously. Do not start the engine while the chain saw hangs in one hand. The saw chain may touch your body. This in very dangerous. 6. When engine has ignited, first push in the choke knob to the first-stage position and then pull the starter again to start the engine. 7. Allow the engine to warm up with the throttle lever pulled slightly. Keep clear of the saw chain as it will start rotating upon starting of engine. •CHECKING THE OIL SUPPLY Make sure to set up the bar and the chain when checking the oil supply. If not, the rotating parts may be exposed. It is very dangerous. After starting the engine, run the chain at medi- um speed and see if chain oil is scattered off as shown in the figure. !WARNING! !WARNING! !WARNING! NOTE NOTE 5.

9EN5. Operating the Engine The chain oil flow can be changed by inserting a screwdriver in the hole on bottom of the clutch side. Adjust according to your work conditions. The oil tank should become nearly empty by the time fuel is used up. Be sure to refill the oil tank every time when refueling the saw. •ADJUSTING THE CARBURETOR The carburetor has been adjusted at the factory. Should your unit need readjustment due to the changes in altitude or operating conditions, please let your skillful dealer make the adjust- ment. A wrong adjustment may cause damage to your unit. If you have to make the adjustment yourself, please follow the procedure below carefully. Before adjusting the carburetor, make sure that the provided air/fuel filters are clean and fresh and the fuel properly mixed. NOTE When adjusting, take the following steps: Be sure to adjust the carbu- retor with the bar chain attached. 1. “H” and “L” needles are restricted within the number of turn as shown below. “H” needle: -1/4 “L” needle: -1/4 2. Start the engine and allow it to warm up in low speed for a few minutes. 3. Turn the idle adjusting screw (T) counter- clockwise so that the saw chain does not turn. If the idling speed is too slow, turn the screw clockwise. 4. Make a test cut and adjust the “H” needle for best cutting power, not for maximum speed. Over revolution of “H” needle causes a lack of power or a poor acceleration. In such a case please turn the “H” needle a little counterclockwise. •CHAIN BRAKE This machine is equipped with an automatic brake tostop saw chain rotation upon occur- rence of kickback during saw cutting. The brake is automatically operated by inertial force, which acts on the weight fitted inside the front guard. This brake can also be operated manually with the front guard turned down to the guide bar. To release the brake, pull up the front guard toward the front handle till a “click” sound is heard. CautionBe sure to confirm brake operation during daily inspection. Checking procedure 1.

10MM10EN5. Operating the Engine 2. Run up the engine to maximum revs. Grip the chain saw by the front handgrip and push the hand guard forwards with the thumb, in the direction of the bar. Release the accelerator lever when the brake is engaged. The chain must stop immediately as soon as the brake is engaged. If the brake is not working correctly, contact your dealer for a check and repair. The clutch will overheat if the engine remains at a high number of revs with the brake engaged. This can lead to damage to the clutch and the brake belt. Release the accelerator lever immediately if the brake is engaged when working. •CARBURETOR ANTI-FREEZE MECHANISM Operating chain saws in temperatures of 0 – 5°C at times of high humidity may result in ice form- ing within the carburetor, and this in turn may cause the output power of the engine to be reduced or for the engine to fail to operate smoothly. This product has accordingly been designed with a ventilation hatch on the right side of the surface of the cylinder cover to allow warm air to be supplied to the engine and to thereby prevent icing from occurring. Under normal circumstances the product should be used in the normal operating mode, i.e., in the mode which it is set at the time of shipment.However when the possibility exists that icing may occur, the unit should be set to operate in the anti-freeze mode before use Continuing to use the prod- uct in the anti-freeze mode even when tempera- tures have risen and returned to normal, may result in the engine failing to start properly or in the engine failing to operate at its normal speed, and for this reason you should always be sure to return the unit to the normal operating mode if there is no danger of icing occurring. HOW TO SWITCH BETWEEN OPERATING MODES 1. Flip the engine switch to turn off the engine. 2. Remove the cover to the air filter, remove the air filter, and then remove the choke knob from the cylinder cover. 3. Loosen the screws holding the cylinder cover in place (i.e., the three screws on the inside and the one screw on the outside of the cover), and then remove the cylinder cover. 4. Press with your finger down on the icing cap located on the right-hand side of the cylinder cover to remove the icing cap. 5. Adjust the icing cap so that the “snow” mark faces upwards and then return it to its original position in the cylinder cover. 6. Fix the cylinder cover back into its original position, and then fix all other parts back into their proper positions. •STOPPING THE ENGINE 1. Release the throttle lever to allow the engine to idle for a few minutes 2. Set the switch to the “O” (STOP) position.

11EN6. Sawing •Before proceeding to your job, read the sec- tion “For Safe Oper- ation”. It is recommend- ed to first practice saw- ing easy logs. This also helps you get accus- tomed to your unit. •Always follow the safety regulations. The chain saw must only be used for cutting wood. It is forbidden to cut other types of material. Vibrations and kickback vary with different mate- rials and the require- ments of the safety reg- ulations would not be respected. Do not use the chain saw as a lever for lifting, moving or splitting objects. Do not lock it over fixed stands. It is forbidden to hitch tools or applications to the PTO other than those specified by the manufacturer. • It is not necessary to force the saw into the cut. Apply only light pressure while running the engine at full throttle. •When the saw chain is caught in the cut, do not attempt to pull it out by force, but use a wedge or a lever to open the way. •GUARD AGAINST KICKBACK !WARNING!•This saw is equipped with a chain brake that will stop the chain in the event of kickback if oper- ating properly. You must check the chain brake operation before each usage by running the saw at full the throttle for 1-2 seconds and pushing the front hand guard forward. The chain should stop immediately with the engine at full speed. If the chain is slow to stop or does not stop, replace the brake band and clutch drum before use. •It is extremely important that the chain brake be checked for proper oper- ation before each use and that the chain be sharp in order to maintain the kick- back safety level of this saw. Removal of the safe- ty devices, inadequate maintenance, or incorrect replacement of the bar or chain may increase the risk to serious personal injury due to kickback. •FELLING A TREE 1. Decide the felling direction considering the wind, lean of the tree, location of heavy branches, ease of completing the task after felling and other factors. 2.While clearing the area around the tree, arrange a good foothold and retreat path. (1) Notch cut (2) Felling cut (3) Felling direction 6. Sawing
12MM12EN6. Sawing 3. Make a notch cut one-third of the way into the tree on the felling side. 4. Make a felling cut from the opposite side of the notch and at a level slightly higher than the bottom of the notch. When you fell a tree, be sure to warn neighboring workers of the dan- ger. Bucking and Limbing •Always ensure your foothold. Do not stand on the log. •Be alert to the rolling over of a cut log. Especially when working on a slope, stand on the uphill side of the log. •Follow the instructions in “For Safe Operation” to avoid kickback of the saw. Before starting work, check the direction of bending force inside the log to be cut. Always finish cutting from the opposite side of the bend- ing direction to prevent the guide bar from being caught in the cut. A log lying on the ground Saw down halfway, then roll the log over and cut from the opposite side. A log hanging off the ground In area “A”, saw up from the bottom one-third and finish by sawing down from the top. In area “B”, saw down from the top one-third and finish by sawing up from the bottom. !WARNING! !WARNING!Cutting the limbs of Fallen Tree First check to which side the limb is bent. Then make the initial cut from the bent side and finish by sawing from the opposite side. Be alert to the springing back of a cut limb. Pruning of Standing Tree Cut up from the bottom, finish down from the top. •Do not work standing on unstable bases or rung ladders. •Do not overreach. •Do not cut above shoulder height. •Always use both your hands to hold the saw. !WARNING! !WARNING!
13EN7. Maintenance Before cleaning, the inspecting or repairing the unit, make sure that engine has stopped and is cool. Disconnect the spark plug to prevent acci- dental starting. •MAINTENANCE AFTER EACH USE 1. Air filter Loosen the knob and remove the air cleaner cover. Take off the filter element and brush off attached sawdust. When the filter is clogged with dust, separate it in halves and shake-wash with gaso- line. When using compressed air, blow from the inside. To assemble the cleaner halves, press the rim until it clicks. When installing the main filter, make sure that the grooves on the filter edge are correctly fit with the projections on the cylinder cover. 2. Oiling port Dismount the guide bar and check the oiling port for clogging. NOTE !WARNING!3. Guide bar When the guide bar is dismounted, remove saw- dust in the bar groove and the oiling port. Grease the nose sprocket from the feeding port on the tip of the bar. 4. Others Check for fuel leakage and loose fastenings and damage to major parts, especially handle joints and guide bar mounting. If any defects are found, make sure to have them repaired before operating the saw again. •PERIODICAL SERVICE POINTS 1. Cylinder fins Dust clogging between the cylinder fins will cause overheating of the engine. Periodically check and clean the cylinder fins after removing the air cleaner and the cylinder cover. When installing the cylinder cover, make sure that switch wires and grommets are positioned correctly in place. Be sure to block the air intake hole. NOTE 7.
