• 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. OPERATION WHEN THE ENGINE IS COLD • Fill the fuel tank with fuel. • Fill the chain oil tank with lubricant. • Turn switch to “RUN” position. • Pull choke all the way out. (Close position) • Push purge bulb 3 to 4 times • Pull starter handle several times until first firing sound. (Hold machine with your knee.) • Push choke all the way in.

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.

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. NOTE If engine does not start after 4 pulls, use cold start procedure. RUNNING • After engine starts, allow it to idle for a few minutes. • Squeeze throttle trigger with throttle control lockout gradually to increase engine speed. Purge bulb RUN START (PULL) Choke knob 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 3 or 4 times.) • Turn switch to “RUN” position. • Pull starter handle. • Choke may be used if necessary but be sure to push it back on first firing sound. • Saw chain starts running 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 to STOP position. (NOTE) When engine does not stop, pull choke out fully to stop engine. Check and repair stop switch before starting the engine again. 8 CUTTING INSTRUCTIONS GENERAL [NOTE] Read the ECHO “CHAIN SAW SAFETY MANUAL” included Kickback 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... 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.) 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 earmuffs or earplugs to protect against objectionable or uncomfortable loud noises. 9 FELLING A TREE 45° DIRECTION OF FALL 2” 2” Direction of fall Hinge Felling cutFirst cut Notch Second cut One-third tree diameter LIMBING A falling tree can seriously damage anything it may hit - a car, a house, a fence, a powerline, or another tree.
