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.

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 the friction between the chain and the guide bar to a minimum and assures a longer service life. Cap indication Fuel/oil tanks are indicated by the following illustrations on the caps. Fuel 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 HARD TO START 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. • Press throttle trigger lockout down while grasping throttle trigger and push in throttle latch. • Move ignition switch to “RUN” position. • Securely hold the chain saw as shown and pull starter handle.
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 3800 r/min approximately. • Confirm proper acceleration and lubrication of chain and bar. • Give several strokes to manual oiler button to confirm extra lubrication. • Do not run the engine at high speed unnecessarily.
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. Kickback motion Kickback motion TESTING THE BRAKE • Start the engine on a solid level surface and run at a fast idle until warm.
