FUEL AND LUBRICANT FUEL STATEMENT GASOLINE - Use 89 Octane (R+M/2) gasoline or gasohol known to be good quality. Gasohol may contain maximum 10% ethyl (grain) alcohol or 15% MTBE (methyl tertiary-butyl ether). Gasohol containing methy (wood) alcohol is not approved. Oil OIL - ECHO brand premium two-stroke 50:1 oil is preferred. Mix oil and gasoline/gasohol according to instructions on the oil container label. Gasoline 50 MIXING - Follow directions on the oil container.
WHEN THE ENGINE IS HARD TO START • • • Press throttle control lockout down while holding throttle trigger and push in latch. Pull starter handle. When engine starts, immediately push throttle trigger up, to release the latch. Purge bulb RUN START (PULL) CAUTION Clutch engages and chain will rotate when engine is started with throttle latch engaged. After engine starts, release throttle trigger to idle engine. Never use the latch for cutting. Use it only when starting the engine.
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 one-man 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...
A falling tree can seriously damage anything it may hit - a car, a house, a fence, a powerline, or another tree. There are ways to make a tree fall where you want it, so first decide where that is! FELLING A TREE 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.
Don’t cut with the saw overhead or the bar in a verticle position. If the saw should kick back you may no have good enough control to prevent possible injury. BUCKING 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. 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.
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: You saw chain can be equipped with either of these bars. Guide à Double Guard Reduced nose radius NOTE: Replacement Guide Bars The following guide bars may be considered to have equivalent kickback energy.
MAINTENANCE AND CARE AIR FILTER Air filter • • • • Check before every use. Pull choke all the way out (Close position). Loosen bolt, and remove air cleaner cover and filter. Brush off dust lightly, or wash it in water and detergent if necessary. Dry it completely before installation. Air cleaner cover AUTOMATIC OILER Oil discharge adjusting screw • The discharge volume of the automatic oiler is adjusted to 3 to 4 cc/min (at 7000 rpm), prior to shipment from factory.
SPARK PLUG • • • • Check periodically. Gap = 0.65 mm (.026”) 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. 0.65 mm (.
LO SPEED MIXTURE ADJUSTMENT 1. Adjust the Lo speed mixture needle in clockwise (CW) until maximum idle RPM (just before lean drop off) is achieved. NOTE: Engine RPM must be allowed to stabilize a minimum of 20 seconds after each adjustment . 2. Turn the Idle speed adjusting screw to achieve idle of 4,000 RPM. 3. Using tachometer, rich down by adjusting Lo speed mixture needle out counter-clockwise (CCW) until engine reaches 3,000 RPM at idle. HI SPEED MIXTURE ADJUSTMENT 1.
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.
• 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 o the gauge tool. - Be sure to round off the front edge of the depth gauge. Depth gauge tool Round off the edge Remove until flat with tool Sharpen bottom 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.
TROUBLESHOOTING Poor performance of the engine and/or cutting mechanism can normally be prevented by carefully following the above 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.
Table 2 Improper fuel used ..................................... Use fuel with correct mixing ratio. Never use gasoline of poor quality. Engine overheated Spark plug defective (burnt) ....................... Replace. As cooling fins clogged, air does not pass well ..................................... Clean fins. Engine keeps running, but chain does not cut clean Ouput (engine speed) insufficient Excessive deposits in combustion chamber ................................. Disassemble and remove carbon.
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 enquire 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.
