ECHO provides an Instruction Manual and a Safety Manual. Both must be read and understood for proper and safe operation. X7503203102 X750003241 04/03 RULES FOR SAFE OPERATION A. Kickback Safety Precaution for Chain Saw Users WARNING! 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. 2. Keep a good firm 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 kickback and maintain control of the saw. Don’t’ let go. Tip contact in some cases may cause a lightning fast 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. 3. Make sure 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. 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. 4. Cut at high engine speeds. 5. Do not overreach or cut above shoulder height. 6. Follow manufacturer’s sharpening and maintenance instructions for the saw chain. 1. With a basic understanding of kickback, you can reduce or eliminate the element of surprise. Sudden surprise contributes to accidents. 7. Only use replacement bars and chains specified by the manufacturer or the equivalent. B. Other Safety Precautions 1. Do not operate a chain saw with one hand! Serious injury to the operator, helpers, bystanders, or any combination of these persons may result from one-handed operation. A chain saw is intended for two-handed use. 4. Use caution when handling fuel. Move the chain saw at least 3 m (10 feet) from the fueling point before starting the engine. 2. Do not operate a chain saw when you are fatigued. 5. Do not allow other persons to be near the chain saw when starting or cutting with the chain saw. Keep bystanders and animals out of the work area. 3. Use safety footwear; snug-fitting clothing; protective gloves; and eye, hearing and head protection devices. 6. Do not start cutting until you have a clear work area, secure footing, and a planned retreat path from the falling tree. Copyright© 2003 By Echo, Incorporated All Rights Reserved. 2 7. Keep all parts of your body away from the saw chain when the engine is running. 14. Keep the handles dry, clean, and free of oil or fuel mixture. 8. Before you start the engine, make sure that the saw chain is not contacting anything. 15. Operate the chain saw only in well-ventilated areas. 9. Carry the chain saw with the engine stopped, the guide bar and saw chain to the rear, and the muffler away from your body. 16. Do not operate a chain saw in a tree unless you have been specifically trained to do so. 17. All chain saw service, other than the items listed in the Instruction Manual maintenance instructions, should be performed by competent chain saw service personnel. (For example, if improper tools are used to remove the flywheel or if an improper tool is used to hold the flywheel in order to remove the clutch, structural damage to the flywheel could occur and could subsequently cause the flywheel to burst.) 10. Do not operate a chain saw that is damaged, improperly adjusted, or not completely and securely assembled. Be sure that the saw chain stops moving when the throttle control trigger is released. 11. Shut off the engine before setting the chain saw down. 12. Use extreme caution when cutting small size brush and saplings because slender material may catch the saw chain and be whipped toward you or pull you off balance. 18. When transporting your chain saw, use the appropriate guide bar scabbard. 19. Spark arrestor mufflers approved to SAE Standard J335b are Standard on ECHO Chain saws to reduce the possibility of forest fires. Do not operate the chain saw with a loose or defective muffler. Do not remove the spark arrestor screen. 13. When cutting a limb that is under tension, be alert for spring back so that you will not be struck when the tension in the wood fibers is released.

B GUIDE BAR AND SAW CHAIN • Follow the instructions enclosed with tip guard to install guard to guide bar. • Remove two guide bar nuts and remove sprocket guard (D). • Mount guide bar (A) on studs, and slide toward sprocket to make saw chain installation easier. • Install saw chain (B) as shown, with cutters facing forward. A C D IMPORTANT Be certain tensioner (C) fits into lower adjuster hole before tightening guide bar nuts. NOTE Move chain brake lever fully rearward to install sprocket guard to saw. • Install sprocket guard (D), and tighten guide bar nuts finger tight. • Adjust saw chain tension, as instructed in “Adjustment, Chain Tension.” ADJUSTMENT, CHAIN TENSION • Loosen two guide bar nuts. • Turn the adjuster screw clockwise until the chain touches the bottom of the bar. • Hold the bar nose up and tighten the chain until there is no clearance between the bar and chain. • Tighten both guide bar nuts with bar nose held up, to eliminate clearance. • Pull the saw chain around the guide bar by hand. Loosen the adjustment, if you feel tight spots. • Start the engine and run at low speed. Stop and readjust, if necessary. UP D 7 FUEL AND LUBRICANT FUEL STATEMENT GASOLINE - Use 89 Octane [R+M/2] (mid grade or higher) gasoline or gasohol known to be good quality. Gasohol may contain up to 10% Ethyl (grain) alcohol or 15% MTBE (methyl tertiary-butyl ether). Gasohol containing methyl (wood) alcohol is NOT approved. TWO STROKE OIL - A two-stroke engine oil meeting ISO-LEGD (ISO/CD 13738) and J.A.S.O. FC Standards must be used. Echo brand premium Power Blend TM Universal 2-Stroke Oil meets these standards. Engine problems due to inadequate lubrication caused by failure to use an ISO-L-EGD and J.A.S.O. FC certified oil, such as Echo premium Power Blend TM, will void the two-stroke engine warranty. (Emission related parts only are covered for two years, regardless of two-stroke oil used, per the statement listed in the Emission Defect Warranty Explanation.) Mixing Instructions 1. Fill an approved fuel container with half of the required amount of gasoline. 2. Add the proper amount of 2-stroke oil to gasoline. 3. Close container and shake to mix oil with gasoline. 4. Add remaining gasoline and remix. 5. Install fuel container cap and wipe any spilled fuel from container and surrounding area. Oil 50 Gasoline Fuel Mix Chart 50:1 (U.S.) (METRIC) GAS OIL GAS OIL Gal. Fl. oz. Liter cc. 1 2 5 2.6 5.1 12.8 4 8 20 80 160 400 IMPORTANT Stored fuel ages. Do not mix more fuel than you expect to use in thirty (30) days, ninety (90) days when a fuel stabilizer is added. Stored two-stroke fuel may separate. ALWAYS shake fuel container thoroughly before each use. TANK INDICATION IMPORTANT Spilled fuel is a leading cause of hydrocarbon emissions. Some states may require the use of automatic fuel shutoff containers to reduce fuel spillage. Contact your ECHO dealer for ordering information. FUEL TANK CHAIN LUBRICANT Proper lubrication of the chain while in operation reduces friction between the chain and the guide bar to a minimum and assures a longer service life. • use bar and chain oil of high quality for this purpose. • Do not use used or reclaimed oil to avoid various oiler problems. • Use ECHO bar and chain oil. • When ECHO bar and chain oil is not available: Use motor oil, etc. • Use bar and chain oil of the following grades: SAE NO. 30 ..... in summer SAE NO. 10 ..... in winter or when cutting resinous trees. • When refueling, also refill chain oil. 8 OIL TANK OPERATION WHEN THE ENGINE IS COLD • • • • • • • • • Move chain brake lever fully forward to engage chain brake before starting. Fill the fuel tank with fuel. Fill the chain oil tank with lubricant. Turn switch (A) to “RUN” position. Pull choke (B) all the way out (close position). Push purge bulb (C) 10 times. Pull starter handle several times until first firing sound is heard. (Hold machine with your knee or foot.) Push choke (B) all the way in. (open position) Pull starter handle again. A CS-345 A CS-300 CS-340 WHEN THE ENGINE IS HARD TO START • • • Press throttle control lockout down while holding throttle trigger, and push in throttle control latch. Pull starter handle. When engine starts, immediately squeeze throttle trigger to release the latch. WARNING C DANGER Clutch engages and chain will rotate when engine is started with throttle control latch engaged. Make sure bar and chain are not touching anything when starting the saw. After engine starts, release throttle trigger to idle engine. Never use the throttle control latch for cutting. Use only when starting the engine. B NOTE Do not pull starter rope out to the maximum possible position. Do not allow recoil handle to snap back against the casing. Securely hold the saw. 9 STARTING WARM ENGINE • • • • Ensure that there is fuel and chain oil in the tanks. (If fuel tank was emptied during previous operation, refill tank and push purge bulb 10 times.) Turn switch (A) to “RUN” position. Pull starter handle. Choke may be used if necessary, but be sure to push it back on first firing sound. A CS-345 A NOTE If engine does not start after 5 pulls, use cold start procedure. CS-300 CS-340 RUNNING • • • • • • • After engine starts, allow it to return to idle. Move chain brake lever fully rearward to release chain brake. Squeeze throttle trigger with throttle control lockout gradually to increase engine speed. Saw chain starts moving when the engine reaches approximately 4200 rpm. Ensure proper acceleration and lubrication of chain and bar. Do not run the engine at high speed unnecessarily. Be sure that saw chain stops moving when throttle trigger is released. STOPPING • Release throttle trigger and turn switch (A) to STOP position. NOTE If engine does not stop, pull choke out fully to stop engine. Check and repair stop switch before starting the engine again. A CS-345 CS-300 CS-340 10 A CUTTING INSTRUCTIONS GENERAL [NOTE] Read the ECHO “CHAIN SAW SAFETY MANUAL” included with your chain saw for additional cutting and safety instructions. In all circumstances the operation of the chain saw is a oneman job. It is difficult at times to take care for your own safety, so don’t assume the responsibility for a helper as well. After you have learned the basic techniques of using the saw, your best aid will be your own good common sense... The accepted way to hold the saw is to stand to the left of the saw with your left hand on the front handlebar and your right hand on the rear handle so you can operate the throttle trigger with your right index finger. Before attempting to fell a tree, cut some small logs or limbs. Become thoroughly familiar with the controls and the responses of the saw. Start the engine, see that it is running properly. Squeeze the trigger to open the throttle wide open and start the cut. If the chain is properly sharpened, the cutting should be relatively effortless. It is not necessary to press down hard to make the saw cut. Pushing the saw too hard will slow the engine and cutting will actually be more difficult. Some material may adversely affect the housings of your ECHO chain saw. (Example: Palm Tree Acid, fertilizer, etc.) To avoid housing deterioration, carefully remove all packed saw dust around clutch and guide bar area and wash with water. Kickback CAUTION Do not let the tip of the bar touch anything while the engine is running. At cutting speed the chain is moving at a high rate of speed. Should the tip contact a limb or log while the chain is moving, the tip will be pushed upward with considerable force. This is known as kickback. Avoid it! CAUTION Wear suitable hearing protective device such as ear muffs or ear plugs to protect against objectionable or uncomfortable loud noises. 11 FELLING A TREE CAUTION DIRECTION OF FALL A falling tree can seriously damage anything it may hit - a car, a house, a fence, a power line, or another tree. There are ways to make a tree fall where you want it, so first decide where that is! Before cutting, clear the area around the tree. You will need good footing while working and you should be able to work the saw without hitting any obstacles. Next, select a path of retreat. When the tree begins to fall you should retreat away from the direction of fall at a 45 degree angle to avoid the trunk kicking back over the stump. 45° Direction of fall Hinge Begin the cut on the side to which the tree is to fall. Cut a notch about 1/3 of the way into the tree as shown. The position of this notch is important since the tree will try to fall “into” the notch. The felling cut is made on the side opposite the notch and at a level about 2” above the bottom of the notch. Do not try to cut through to the notch with the felling cut. The remaining wood between the notch cut and felling cut (about 2”) will act as a hinge when the tree falls, guiding it in the desired direction. When the tree starts to fall, kill the engine, place the saw on the ground and make your retreat quickly. 2” First cut Notch Felling cut 2” Second cut One-third tree diameter To fell big trees with a diameter exceeding twice the bar length, start the notching cuts from one side and draw the saw through to the other side of the notch. Start the back cut on one side of the tree, pivoting the saw through to form the desired hinge on that side. Then remove the saw for the second cut. Insert the saw in the first cut, very carefully so as not to cause kickback. The final cut is made by drawing the saw forward in the cut to reach the hinge. LIMBING Limbing a fallen tree is much the same as bucking. Never limb on the tree that you are standing. When limbing, caution is the word. Be careful of the tip touching other limbs. Always use both hands. 12 Don’t cut with the saw overhead or the bar in a vertical position. If the saw should kick back you may not have good enough control to prevent possible injury. Bucking is the sawing of a log or fallen tree into smaller pieces. There are a few basic rules which apply to all bucking operations. BUCKING Uphill position Keep both hands on the handles at all times. Support logs if possible. When cutting on a slope or hillside, always stand uphill. Keep in mind that the wood is heavy and that it will bend and pinch the saw if improperly supported. FINISH CUT The trunk will weaken at the point where you make the cut unless the tree is lying on perfectly flat ground or supported as shown. FIRST CUT Board or flat stones KICKBACK If you make the cut with the tree on the ground, don’t let the saw’s chain dig into the earth; it is harmful for the saw, and you stand a good chance of being struck by flying debris. To cut the trunk, use the bucking and two-cut sequence shown. The first cut should be no deeper than one-third the trunk diameter. WARNING: KICKBACK IS DANGEROUS • Improper thrust cutting. Kickback is generated when the rotation of the chain is arrested for some reason. The most dangerous effect of this action occurs when the nose of the bar contacts another object, the chain is momentarily stopped and all the energy of the engine throws the bar upwards and backwards towards the operator. The chain saw industry and government agencies have attempted to prescribe various safety devices, but the best protection is to avoid kickback. Comply with the Safety Precautions as listed on page 2 of this manual. • When the bar nose hits another tree, etc. 13 INFORMATION Kickback Safety Features The following features are recommended for this model as Kickback Safety Features. • Double Guard Low Kick Type Guide Bar or Asymmetrical Low Kick Type Guide Bar Note: Your saw chain can be equipped with either of these bars. Double Guard Bar Reduced nose radius NOTE Use Oregon® replacement guide bars. The following guide bars may be considered to have equivalent kickback energy. • Sprocket nose guide bars of the same length and nose radius, same pitch and having the same number of teeth. • A hard nose guide bar having the same length and nose radius as a sprocket nose bar. • Low Kick Guard Link Type Saw Chain The low kick guard link chain must be maintained correctly. Follow instruction “SETTING THE CHAIN” in Instruction Manual. • Front Hand Guard (Chain Brake Actuating Lever) The front handle guard must be installed correctly and kept in good condition. • Chain Brake Chain brake must be maintained correctly. Follow instruction “CORRECT USE OF CHAIN BRAKE” in Instruction Manual. WARNING DANGER Using improper replacement components or removing safety devices may result in serious or fatal injury. 14 MAINTENANCE AND CARE AIR FILTER A C • • • • Check before every use. Pull choke (A) all the way out (close position). Loosen bolt and remove air cleaner (B) cover and filter (C). Lightly brush dust off filter, and inspect for damage. AUTOMATIC OILER • B The discharge volume of the automatic oiler is adjusted to 3 to 4 cc/mm (@ 7000 rpm) prior to shipment from the factory. Always check oil discharge when in use. Turn adjusting screw (D) counter-clockwise to increase oil volume, clockwise to decrease oil volume. • • D OIL STRAINER • E Check periodically. - Do not allow dust to enter into oil tank. - Clogged oil strainer will affect the normal lubricating system. - Pick it up through oil port. - If the strainer (E) is dirty, wash it in gasoline. - When the inside of the tank gets dirty, rinsing the tank out with gasoline will clean it. FUEL STRAINER • Check periodically. - Do not allow dust to enter fuel tank. - Clogged strainer will cause difficulty in starting engine or abnormalities in engine performance. - Pick up the fuel strainer (F) through fuel inlet port with a piece of steel wire, or the like. - When the strainer is dirty, wash it in suitable cleaning fluid. - When the inside of the fuel tank is dirty, rinsing the tank out with suitable cleaning fluid will clean it. GUIDE BAR AND OIL HOLES • Clean after each use - Clean the grooves (G) of the guide bar with, for example, a small screwdriver. - Clean oil holes (H) with a wire. Reverse guide bar periodically. • SPROCKET F • H G J A damaged sprocket (J) will cause premature damage or wear of saw chain. - When the sprocket has worn out 0.5mm (.020”) or more, replace it. Check sprocket when you install new chain. Replace it if worn. Clean sprocket, clutch and bar mount area before installation of bar. • • IMPORTANT Some tree sap and resins are corrosive. Thoroughly wash the guide bar and sprocket areas after each use, then coat metal parts with light oil. 15 SPARK PLUG • Check periodically • Gap = 0.65mm (.026 in.) • Replace if either electrode is worn, or if the insulator is fouled by oil or other deposits. • Torque = 145 – 155 kg*cm (125 – 135 in. lb.) CAUTION: Do not over-torque. COOLING SYSTEM CLEANING • Remove spark plug lead. • Remove two (2) muffler cover screws and muffler cover. • Remove four (4) recoil starter housing screws and starter housing. • Use a stiff bristle cleaning brush (do not us a metal brush) to remove dirt from cylinder fins in muffler and ignition coil areas. CARBURETOR ADJUSTMENT Engine Break-In New engines must be operated a minimum duration of two tanks of fuel break-in before carburetor adjustments can be made. During the break-in period your engine performance will increase and exhaust emissions will stabilize. Idle speed can be adjusted as required. High Altitude Adjustment High altitude adjustment may be required for proper operation of this engine. IMPORTANT Engine operation at altitudes above 2000 feet may require adjustment of the carburetor high and low-speed needles. Turn the high-speed needle lean (CW) until the engine runs between 10,500 and 11,500 maximum RPM. Below 2000 feet altitude, turn the high-speed needle rich (CCW) until the engine runs between 10,500 and 11,500 maximum RPM. 16 Before starting the unit for adjustment, check the following items: • The correct spark plug must be clean and properly gapped. • The air filter element must be clean and properly installed. • The muffler spark arrestor screen and exhaust port must be clear of carbon. • The standard bar and chain combination (see page 4) must be installed to the power head, and properly tensioned. A 1. Start engine and run for several minutes to reach operating temperature. 2. Stop engine. Remove grommet cover (A) over “H” and “L” limiter needles. B 3. Turn HI speed needle (H) CCW (counter clockwise) to stop. Turn LO speed needle (L) CCW (counter clockwise) to stop. 4. Idle Speed Adjustment. • Start engine and turn “idle” speed adjustment screw (B) CW until the saw chain begins to move, then turn the screw CCW until saw chain stops moving. Turn screw CCW an additional 1/4 turn. 5. Accelerate to full throttle for 2-3 seconds to clear excess fuel from engine then return to idle. Accelerate to full throttle to check for smooth transition from idle to full throttle. If engine stops or stalls after full warm up return the unit to your authorized ECHO dealer for repair. 6. Check HI speed RPM at W.O.T. (Wide Open Throttle). HI speed RPM should be set between 10,500 and 11,500 RPM’s. 7. Check idle speed and reset if necessary. If a tachometer is available, idle speed should be set between 2,700 and 3,300 RPM’s. CAUTION! • • 17 When starting, idling adjustment speed should be adjusted not to rotate the saw chain. When there is trouble with the carburetor, refer to your distributor or dealer. CHAIN AND GUIDE BAR COMBINATION The following combinations may be used on CS-300, CS-340 or CS-345.

Only use saw chain designated as, “LOW-KICKBACK,” that meets the ANSI B175.1-2000 Standard, and the Echo guide bar specified. SETTING THE SAW CHAIN For setting saw chains, round file (4 mmø: 5/32”) and flat file are used. • To keep correct position and correct angle, use the file holder. - Round file and flat file are available from your Echo Dealer. • File cutters as below. To sharpen other type chain, follow chain manufacturer’s instructions Type : 91VG 1/5 30° Depth gauge Keep this angle HOLD FILE HOLDER LEVEL PUSH FILE AS SHOWN • ONE FIFTH OF FILE DIAMETER REMAINS ABOVE CUTTER EDGE Place the depth gauge tool firmly on guide bar so that depth gauge protrudes. Then file top of depth gauge with flat file until flat with top of the gauge tool. - Be sure to round off the front edge of the depth gauge. Depth gauge tool Remove until flat with tool Sharpen bottom edge 18 Round off the edge • Properly filed cutters are shown below. (Top plate angle) (Side plate angle) (Top plate cutting angle) 60° 85° (Depth gauge) 0.64 mm (0.025”) Parallel 30° • • • • When setting of the chain is finished, soak it in oil and wash away filings completely before using. When chain has been filed on the bar, supply sufficient oil to it, rotate the chain slowly to wash away the filings before using again. If the chain saw is operated with filings clogged in the groove, the saw chain and the guide bar will be damaged prematurely If the saw chain becomes soiled with resin, for instance, clean it with kerosene and soak it in oil. CHAIN TYPE AND SPROCKET PITCH (SPROCKET) Saw chain should be used with corresponding pitched sprocket. To identify chain type and pitch of sprocket, check as follows. • • Chain type number (A) is stamped on drive link. Sprocket pitch (B) is stamped on clutch drum. (DRIVE LINK) Number indicates Chain type Number indicates Chain type 91 A 19 91S B TROUBLESHOOTING Poor performance of the engine and/or cutting mechanism can normally be prevented by carefully following these instructions. Poor performance can easily be corrected even by a beginner. When the engine does not function properly check the following three (3) points first. • Is the engine compression adequate? • Is fuel system in good condition and is enough fuel being supplied? • Is electrical system in good condition and is spark plug operating normally? When there is serious trouble with the unit, do not try to repair it yourself but have your distributor or dealer do it for you. For detailed TROUBLESHOOTING refer to tables 1 and 2.

Drain fuel tank, pull starter slowly a few times to drain fuel from carburetor. Pour a small amount of clean two-stroke oil into spark plug hole, pull starter and crank engine until the piston is at TOP DEAD CENTER. Store in a dry area, free from dust. 21 CORRECT USE OF CHAIN BRAKE The installation of a chain brake may be mandatory by law or as stipulated by insurance regulations in your area of operation. You should inquire through local government offices, your employer or your local dealer to ensure that your chain saw conforms to the required safety standard. Echo chain brakes have been designed and tested to comply with international safety standards as follows. USA: ANSI Standard B175.1-2000 Safety Requirement for chain saws Canada: CSA Standard Z 62.1 CHAIN SAWS WARNING : • ANSI Standard B175.1-2000 stipulates that the brake shall stop the chain in 0.10 seconds (one tenth) at an engine speed of 8000 RPM. It is the responsibility of the Owner/Operator to ensure that the brake is serviced, adjusted and tested strictly in accordance with the instructions as detailed herein in order to ensure that the brake performance is maintained in compliance with the Standard B175.1-2000. Kickback Motion: Function: • • When the bar nose hits another tree, etc. When the lever is pushed forward, chain brake instantly works to stop the chain. Release: • Improper thrust cutting. • When the lever is fully pulled toward the operator, brake is released. INSTALLATION TESTING THE BRAKE • • Start the engine on a solid level surface and run at a fast idle until warm. • Hold the saw firmly by the handles and accelerate the engine to a fast idle. • Slowly operate the chain brake lever while holding the saw firmly on the ground. When the brake lever trips, the chain should stop. Immediately release the throttle trigger. Echo recommends that the chain brake should be serviced by an authorized Echo servicing dealer. OPERATION • Set the lever in the released position before starting to cut. • If the brake is tripped by kick back reaction, the chain will stop. Immediately release the throttle to avoid possible damage to the engine or clutch. • Do not attempt to operate the engine with the brake engaged. CAUTION DO NOT ALLOW THE SAW TO TIP FORWARD IN ORDER TO AVOID DAMAGE TO THE CHAIN. If the chain does not stop, immediately return the saw to your authorized Echo dealer for repair. 22 NOTES 23 SERVICING INFORMATION PARTS Genuine ECHO Parts and ECHO REPOWERTM Parts and Assemblies for your ECHO products are available only from an Authorized ECHO Dealer.
