1. For safe operation

1. Never operate a chain saw when

you are fatigued, ill, or upset, or under the influence of medica- tion that may make you drowsy, or if you are under the influence of alcohol or drugs.

2. Use safety footwear, snug fitting

clothing and eye, hearing and head protection devices. Use the vibration-proof glove.

3. Keep the saw chain sharp and

the saw, including the AV system, well maintained. A dull chain will increase cutting time, and press- ing a dull chain through wood will increase the vibrations transmit- ted to your hands. A saw with loose components or with dam- aged or worn AV buffers will also tend to have higher vibration lev- els.

4. All the above mentioned precau-

tions do not guarantee that you will not sustain whitefinger diseaseor carpal tunnel syn- drome. Therefore, continual and regular users should monitor closely the condition of their hands and fingers. If any of the above symptoms appear, seek medical advice immediately.

5. Always use caution when han-

dling fuel. Wipe up all spills and then move the chain saw at least 3 m from the fueling point before starting the engine.

6. Eliminate all sources of sparks or

flame (i.e. smoking, open flames, or work that can cause sparks) in the areas where fuel is mixed, poured, or stored.

7. Do not smoke while handling fuel

or while operating the chain saw.

8. Do not allow other persons to be

near the chain saw when start- ing or cutting. Keep bystanders and animals out of the work area. Children, pets and bystanders should be a minimum of 10 m away when you start or operate the chain saw.

9. Never start cutting until you have

a clear work area, secure foot- ing, and a planned retreat path from the falling tree.

10. Always hold the chain saw firmly

with both hands when the engine is running. Use a firm grip with thumb and fingers encircling the chain saw handles.

11. Keep all parts of your body away

from the saw chain when the en- gine is running. 12.Before you start the engine, make sure the saw chain is not contacting anything.

13. Always carry the chain saw with

the engine stopped, the guide bar and saw chain to the rear, and the muffler away from your body.

14. Never modify the unit or remove

the safety components in any way. Do not use your unit for any job except that for which it is intended. Use only genuine Tanaka replace- ment parts as recommended by the manufacturer.

15. Always inspect the chain saw be-

fore each use for worn, loose, or damaged parts. Never operate a chain saw that is damaged, im- properly adjusted, or is not com- pletely and securely assembled. Be sure that the saw chain stops moving when the throttle control trigger is released.

16. All chain saw service, other than

the items listed in the Owner’s Manual, should be performed by competent chain saw service personnel. (E.g., if improper tools are used to remove the flywheel, or if an improper tool is used to hold the flywheel in order to re- move the clutch, structural dam- age to the flywheel could occur which could subsequently cause the flywheel to disintegrate.)

17. Always shut off the engine be-

fore setting it down.ECV-5601

ting small size brush and sap- lings because slender material may catch the saw chain and be whipped toward you or pull you off balance.

19. When cutting a limb that is un-

der tension, be alert for spring- back so that you will not be struck when the tension in the wood fibers is released. 20.Never cut in high wind, bad weather, when visibility is poor or in very high or low temperatures. Always check the tree for dead branches which could fall during the felling operation.

21. Keep the handles dry, clean and

free of oil or fuel mixture.

22. Operate the chain saw only in

well ventilated areas. Never start or run the engine inside a closed room or building. Exhaust fumes contain dangerous carbon mon- oxide.

23. For respiratory protection, wear

a protection mask while emitting the chain oil mist and dust from sawdust.

24. Do not operate the chain saw in

a tree unless specially trained to do so.

25. Guard against kickback. Kick-

back is the upward motion of the guide bar which occurs when the saw chain at the nose of the guide bar contacts an object. Kickback can lead to dangerous loss of control of the chain saw. 26.When transporting or storage your chain saw, make sure the appropriate guide bar protector is in place.

27. Clean and maintenance the unit

carefully and store it in the dry place.

• 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 con- tact in some cases may cause a lightning fast reverse reac- tion, 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 on the safety devices built into your saw. As a chain saw user you should take several steps to keep cutting jobs free from ac- cident or injury. (1) With a basic understanding of kickback you can reduce or eliminate the element of surprise. Sudden surprise contributes to accidents. (2) Keep a good grip on the saw with both hands, the right hand on the rear handle, and the left hand on the front handle, when the engine is running. Use a firm grip with thumbs and fingers encircling the chain saw handles. A firm grip will help you reduce kick- back and maintain control of the saw. (3) Make certain that the area in which you are cutting is free from obstructions. 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 saw. (4) Cut at high engine speeds. (5) Do not overreach or cut above shoulder height. (6) Follow the manufacturer’s sharp- ening and maintenance instruc- tions for the saw chain. (7) Only use replacement bars and chains specified by the manufac- turer or the equivalent.ECV-5601 GB-6

5. Fuel and Chain Oil

• Gasoline is very flammable. Avoid smoking or bringing any flame or sparks near fuel. Make sure to stop the engine and allow it cool before refuel- ing the unit. Select outdoor bare ground for fuel- ing and move at least 3 m (10 ft) away from the fueling point before starting the engine. agitate depending on oil ingredients, sufficient agi- tation is necessary for the engine to last long. Be careful that, if the agitation is insufficient, there is an increased danger of early piston seizing due to ab- normally lean mixture.

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

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

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.

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 blocking, or piston ring sticking.

4. Mixed fuels which have been left unused for a

period of one month or more may clog the carbu- retor and result in the engine failing to operate prop- erly.

5. In the case of storing the product for a long period

of time, clean the fuel tank after rendering it empty. Next, activate the engine and empty the carburetor of the composite fuel.

6. In the case of scrapping the used mixed oil con-

tainer, scrap it only at an authorized repository site. NOTE As for details of quality assurance, read the description in the section Limited Warranty carefully. Moreover, nor- mal wear and change in product with no functional in- fluence are not covered by the warranty. Also, be care- ful that, if the usage in the instruction manual is not ob- served as to the mixed gasoline, etc. described therein, it may not be covered by the warranty. ■ CHAIN OIL Use motor oil SAE #10W-30 all year round or SAE #30 ~ #40 in summer and SAE #20 in winter. NOTE Do not use wasted or regenerated oil that can cause damage to the oil pump.

• The Tanaka Kogyo engines are lubricated by oil spe- cially formulated for air-cooled 2-cycle gasoline en- gine use. If Tanaka Kogyo oil is not available, 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-cooling type) mixed oil.

• Exhaust emission are controlled by the funda- mental engine parameters and components (eq., carburation, ignition timing and port timing) with- out addition of any major hardware or the intro- duction 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 than prescribed, there is a danger that the engine tem- perature may rise and an engine problem such as piston seizing may consequently 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.

• Pay attention to agitation.

1. Measure out the quantities of gasoline and oil to be

2. Put some of the gasoline into a clean, approved fuel

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 toECV-5601 GB-10

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. WARNING

• 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 medium speed and see if chain oil is scattered off as shown in the figure. The chain oil flow can be changed by inserting a screw- driver in the hole on bottom of the clutch side. Adjust according to your work conditions. NOTE The oil tank should become nearly empty by the timefuel is used up. Be sure to refill the oil tank every timewhen refueling the saw.■ ADJUSTING THE CARBURETORThe carburetor on your unit has been factory adjusted,but may require fine tuning due to a change in operat-ing conditions.Before adjusting the carburetor, make sure that the pro-vided air/fuel filters are clean and fresh and the fuel prop-erly mixed.When adjusting, take the following steps: NOTE Be sure to adjust the carburetor with the bar chain at- tached. WARNING

• 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

3. While holding the throttle lever together with the

throttle interlock, push in the side latch and release the throttle lever to hold it at the starting position.

4. Pull out the choke knob to the closed position.

NOTE 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). NOTE 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.

5. While holding the saw unit securely on the ground,

pull the starter rope vigorously. WARNING

• 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. Operating the Engine

1. Release the throttle lever to allow the engine to idle

2. Set the switch to the “O” (STOP) position.

Carburetor anti-freeze mechanism Operating chain saws in temperatures of 0 – 5°C at times of high humidity may result in ice forming within the car- buretor, and this in turn may cause the output power of the engine to be reduced or for the engine to fail to op- erate smoothly. This product has accordingly been designed with a ven- tilation hatch on the right side of the surface of the cylin- der 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 to 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. WARNING

• Continuing to use the product in the anti-freeze mode even when temperatures have risen and returned to normal, may result in the engine failing to start prop- erly 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 air cleaner cover from the cylinder cover

3. Loosen a screw and remove the screen on the back

of the air cleaner cover.

4. Turn the screen a half and reinstall to the cover.

When using the saw with the anti-freeze mode, frequently check the screen and keep it clean of saw dust.

1. H and L needles are restricted within the number of

turn as shown below. H needle : -

2. Start the engine and allow it to warm up in low speed

3. Turn the idle adjusting screw (T) counterclockwise

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. ■ CHAIN BRAKE This machine is equipped with an automatic brake to stop saw chain rotation upon occurrence 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. [Caution] Be sure to confirm brake operation during daily inspec- tion. How to confirm:

1) Turn off the engine.

2) Holding the chain saw horizontally, release your hand

from the front handle, hit the tip of the guide bar to a stump or a piece of wood, and confirm brake op- eration. Operating level varies by bar size. In case the brake is not effective, ask our dealer for inspection and repairs. If the engine keeps rotating at high speed with the brake engaged, the clutch will overheat causing trouble. When the brake engages during operation, immediately release the throttle lever to stop the engine.

• Before proceeding to your job, read the section “For Safe Op- eration”. It is recommended to first practice sawing easy logs. This also helps you get accus- tomed to your unit.

• Always follow the safety regu- lations. The chain saw must only be used for cutting wood. It is forbidden to cut other types of material. Vibrations and kickback vary with differ- ent materials and the require- ments of the safety regulations would not be respected. Do not use the chain saw as a lever for lifting, moving or splitting ob- jects. 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.

• When completing a cut, be ready to hold up the unit as it breaks into clear, so it will not follow through and cut your legs, feet or body, or contact an obstruction.

• Always keep the spiked bumper face to a tree, because the chain may suddenly be drawn into a tree.

• 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

• This saw is equipped with a chain brake that will stop the chain in the event of kickback if operating prop- erly. You must check the chain brake operation before each usage by run- ning the saw at full the throttle for I - 2 seconds and pushing the front hand guard forward. The chain should stop immediately with the en- gine 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 operation before each use and that the chain be sharp in order to main- tain the kickback safety level of this saw. Removal of the safety devices, inadequate maintenance, or incor- rect replacement of the bar or chain may increase the risk to serious per- sonal injury due to kickback.

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.

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. WARNING

• When you fell a tree, be sure to warn neighboring workers of the danger. Bucking and Limbing WARNING

• 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 bending direction to prevent the guide bar from being caught in the cut. Notch cut Felling cut Felling direction WARNINGECV-5601

• Be alert to the springing back of a cut limb. Pruning of Standing Tree Cut up from the bottom, finish down from the top. WARNING

• Do not cut above shoulder height.

• Always use both your hands to hold the saw.

When the guide bar is dismounted, remove sawdust in the bargroove and the oiling port.Grease the nose sprocket from the feeding port on the tip ofthe bar.

Check for fuel leakage and loose fastenings and damage tomajor parts, especially handle joints and guide bar mounting.If any defects are found, make sure to have them repairedbefore operating the saw again.

Dust clogging between the cylinder fins will cause overheat-ing of the engine. Periodically check and clean the cylinderfins after removing the air cleaner and the cylinder cover. Wheninstalling the cylinder cover, make sure that switch wires andgrommets are positioned correctly in place. NOTE Be sure to block the air intake hole. WARNING

• Before cleaning, the inspecting or repairing the unit, make sure that engine has stopped and is cool. Dis- connect the spark plug to prevent accidental starting.

Dust on the cleaner surface can be removed by tapping acorner of the cleaner against a hard surface. To clean dirt inthe meshes, split the cleaner into halves and brush in gaso-line. When using compressed air, blow from the inside.To assemble the cleaner halves, press the rim until it clicks. NOTE When installing the main filter, make sure that the grooves on the filter edge are correctly fit with the projections on the cylinder cover.

Dismount the guide bar and check the oiling port for clogging.ECV-5601 GB-14 Place the file on the cutter and push straight forward. Keep the file position as illustrated. After each cutter has been filed, check the depth gauge and file it to the proper level as illustrated.

Clean the electrodes with a wire brush and reset the gap to

0.65 mm as necessary.

Check for cracks and for excessive wear interfering with the chain drive. If the wear is considerable, replace it with new one. Never fit a new chain on a worn sprocket, or a worn chain on a new sprocket.

6. Front and Rear dampers

Replace if adhered part is peeled or crack is observed on the rubber part.

(a) Using a wire hook, take out the filter from the filler port. (b) Disassemble the filter and wash with gasoline, or replace with a new one if needed. NOTE

• After removing the filter, use a pinch to hold the end of the suction pipe.

• When assembling the filter, take care not to allow fil- ter fibers or dust inside the suction pipe.

With a wire hook, take out the oil filter through the filler port and clean in gasoline. When putting the filter back into the tank, make sure that it comes to the front right corner. Also clean off dirt in the tank. Fuel filter
