OPERATOR SAFETY VIBRATION AND COLD EYE AND HEARING PROTECTION • It is believed that a condition called Raynaud’s Phenomenon, which affects the fingers of certain individuals, may be brought about by exposure to vibration and cold. Exposure to vibration and cold may cause tingling and burning followed by loss of color and numbness in the fingers. The following precautions are strongly recommended because the minimum exposure which might trigger the ailment is unknown.
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.

Clutch 4. Mount guide bar on stud and slide toward clutch to make saw chain installation easier. Install chain with cutters on top of guide bar facing forward. 5. Unlock the chain brake, and install the clutch cover (and spiked bumper; option) over the guide bar stud. Ensure chain tension adjuster pin fits into the guide bar adjuster hole, brake band is positioned around clutch drum. Tighten clutch cover nut finger tight. 6. Turn saw over, and check brake band for correct position on clutch drum.
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 teriary-butyl ether). Gasohol containing methyl (wood) alcohol is NOT approved. WARNING Alternative fuels, such as E-20 (20 % ethanol), E-85 (85 % ethanol) or any fuels not meeting above requirements are NOT approved for use in ECHO 2-stroke gasoline engines.
HANDLING FUEL MIXING INSTRUCTIONS 1. Fill an approved fuel container with half of the required amount of gasoline. DANGER Fuel is VERY flammable. Use extreme care when mixing, storing or handling or serious personal injury may result. • Use an approved fuel container. • DO NOT smoke near fuel. • DO NOT allow flames or sparks near fuel. • Fuel tanks/cans may be under pressure. Always loosen fuel caps slowly allowing pressure to equalize.
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. Cap indication Oil/fuel tanks are indicated by the following illustrations on the caps. Oil tank cap • 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.
WHEN THE ENGINE IS COLD Chain brake CAUTION Make sure the bar and chain are free from any obstruction when starting the chain saw. • Move chain brake lever fully forward to lock chain brake before starting. Start / Run • Fill the fuel tank with fuel mixture. It is not permitted to fill fuel above the shoulder level of fuel tank. Ignition switch Purge pump • Fill the chain oil tank with lubricant. Do not over fill. • Move ignition switch to “RUN” position.
RUNNING Unlock chain brake • When engine starts, keep idling for a few minutes. • Set the brake lever in the unlocked position before starting to cut. • Pull throttle trigger gradually and increase revolution of the engine. • The chain starts running when the engine reaches 4400 r/min approximately. • Confirm 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.
CUTTING INSTRUCTION GENERAL CAUTION • Read the ECHO “CHAIN SAW SAFETY MANUAL” included with your chain saw for additional cutting and safety instructions. • Wear suitable hearing protection such as earmuffs or earplugs to protect against objectionable or uncomfortable loud noises. • 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.
FELLING 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.
LIMBING Limbing a fallen tree is much the same as bucking. Never stand on the tree that you are limbing. When limbing, caution is the word. Be careful of the tip touching other limbs. Always use both hands. Don’t cut with the saw overhead or aligned vertically with your body. If the saw should kickback, you may not have 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.
CHAIN BRAKE OPERATION • Set the lever in the unlocked position before starting to cut. • If the brake is tripped by kickback 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 locked. Improper thrust cutting 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 End of the guide bar may be placed at the height of about 55 cm (22 in.). Kickback produced from the tip of the guide bar will trip the automatic chain brake. To make sure that the automatic chain brake operates properly, follow these steps: 1. Stop the engine. 2. Hold the saw with the guide bar approximately 55 cm (22 in.) above a wooden surface. Right hand should hold the rear handle, and left hand should hold the front handle. 3.
