RULES FOR SAFE OPERATION A. Kickback Safety Precautions 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. 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.
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. 13.When cutting a limb that is under tension, be alert for springback so that you will not be struck when the tension in the wood fibers is released. 14.Keep the handles dry, clean, and free of oil or fuel mixture. 6.Do not start cutting until you have a clear work area, secure footing, and a planned retreat path from the falling tree. 15.

OPERATOR SAFETY HOT HUMID WEATHER • Heavy protective clothing can increase operator fatigue which may lead to heat stroke. Schedule heavy work for early morning, or late afternoon hours when temperatures are cooler. To reduce the risk of RSI/CTS, do the following: • Avoid using your wrist in a bent, extended or twisted position. • Take periodic breaks to minimize repetition and rest your hands. • Reduce the speed and force in which you do the repetitive movement.
SPARK ARRESTOR MUFFLER • The spark arrestor muffler controls the exhaust noise and prevents hot, glowing particles of carbon from leaving the muffler. Make sure the spark arrestor screen is in good repair and properly seated in the muffler. • Certain internal combustion engines operated on forest, brush, and/or grass-covered areas in the states of Washington, Oregon, Idaho, California Minnesota, New Jersey and Maine, are required to be equipped with a spark arrestor. This requirement also applies to all U.
PREPARATION FOR USE CAUTION • All adjustment, should be made cold. • Always wear gloves when working on chain. MOUNTING GUIDE BAR AND CHAIN Bar hole • Unscrew two nuts and remove clutch cover. • Install the spiked bumper on the front of machine. (Use two bolts 5×12) Clutch cover Spiked bumper Two bolts 5×12 • Mount bar and slide toward clutch to make saw chain installation easier. • Install saw chain as shown.
FUEL AND LUBRICANT FUEL STATEMENT Oil GASOLINE-Use 89 Octane [ R+M ] gasoline or 2 gasohol known to be good quality. Gasohol may contain maximum 10% ethyl (grain) alcohol or 15% MTBE (methylteriary-butyl ether). Gasohol containing methyl (wood) alcohol is not approved. 1 Gasoline 50 TWO-STROKE OIL - Use 50 : 1 two-stroke ECHO oil only. Engine problems due to inadequate lubrication caused by failure to use 50 : 1 ECHO oil will void the warranty on your ECHO product.
OPERATION WHEN THE ENGINE IS COLD Chain brake • Fill the fuel tank with fuel. • Fill the chain oil tank with lubricant. • Press hand guard forward. (Chain brake ACTIVATED position) • Turn ignition switch upside. (“RUN” position) • Pull choke control knob all the way out. (Choke position) Stop switch CAUTION Make sure bar and chain are free from any obstruction when starting the saw. Start • Make sure guide bar and saw chain are not touching anything when starting the saw.
RUNNING • When engine starts, keep idling for a few minutes. • Pull throttle trigger gradually and increase revolution of the engine. • The chain starts running when the engine reaches to 3,800 r/min approximately. • Confirm proper acceleration and lubrication of chain and bar. STOPPING • Release throttle trigger and turn switch down. (“STOP” position) Stop NOTE When engine does not stop, pull choke control knob out fully to stop engine. Check and repair stop switch before starting the engine again.
CUTTING INSTRUCTION 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.
FALLING THE TREE 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.
CAUTION Wear suitable hearing protective device such as earmuffs or earplugs to protect against objectionable or uncomfortable loud noises. Don’t cut with the saw overhead or the bar in a vertical position. If the saw should kick back, you may not have well 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. Keep both hands on the handles at all times.
CHAIN BRAKE 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 prevent to the engine or clutch. • Do not attempt to operate the engine with the brake engaged. Kickback motion 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.
AUTOMATIC CHAIN BRAKE The automatic chain brake stops the operation of the saw chain in such a manner that kick-back action produced at the end of the guide bar automatically actuates the chain brake. To make sure that the automatic chain brake operates properly, proceed as follows: 1) Stop the engine of the chain saw. 2) Operate the front and rear handles with hands (grip them lightly), so that the guide bar may be placed at the height of about 35 cm as shown in Fig.
MAINTENANCE AND CARE CARBURETTOR ADJUSTMENT T ; Idle adjusting screw Every unit is run at the factory and the carburettor is set in compliance with California Emission Regulations. In addition, the carburettor is equipped with “H” (High Speed Needle) and “L” (Low Speed Needle) needle adjustment limited that prevent settings outside acceptable limits. 1. Before adjusting carburettor clean or replace air filter and muffler, “Spark Arrestor Screen”. 2.
AIR FILTER Cleaner cover knob • Check before every use. • Loosen cleaner cover knob and remove air cleaner cover and filter. • Brush off dust lightly, or clean with compressed air, or replace the air filter. • Reinstall filter and cover. Air cleaner cover Spark plug Air filter cover Air filter Cylinder cover CYLINDER FINS • Check periodically. • Clogged fins will result in poor engine cooling. • Remove dirt and dust from between fins to let cooling air pass easily. SPARK PLUG • Check periodically.
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. • Pull the fuel strainer out through fuel inlet port with a piece of steel wire or the like. • When the strainer is dirty, replace it. • When the inside of the fuel tank is dirty, rinsing the tank out with gasoline can clean it. Oil strainer OIL STRAINER • Check periodically. • Do not allow dust to enter into oil tank.
SPROCKET Worn : 0.5 mm (0.020 in) • The damaged sprocket will cause premature damage or wear of saw chain. - When the sprocket has worn out 0.5 mm (0.020 in) or more, replace it. • Check sprocket when you install new chain. Replace it if worn. GUIDE BAR Groove • Clean before using. - Clean the groove of the guide bar with, for example, a small screwdriver. - Clean oil holes with a wire. • Clean sprocket, clutch and bar mount area before installation of bar.
SETTING SAW CHAIN • For setting saw chain, round file (4 mm dia. 5/32 inch) and flat file are used. • To keep correct position and correct angle, use the file holder (Sure Sharp). - Round file (P-No. 897510-03931) and flat file (P-No. 897511-00230) are optional. - Inquire about the file holder, if desired.
Properly filed cutters are shown as illustration. 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.
WINTER KIT Use the winter kit with chain saw to prevent a carburettor’s trouble in winter season. Installation of the kit is as follows. • AIR CLEANER COVER - Remove air cleaner cover. Remove plug located inside of cover front and put the plug into another grooved position as shown in the illustration and mount cover so as to allow warm air to flow in from front. • SNOW PROTECTOR (Option) - Snow protector prevents that snow gets into the unit by fan cover in snow fall or laying snow.
