Rules for safe operation 1. General precautions Operator's manual Read the operator's manual for your chain saw carefully. Be thoroughly familiar with the chain saw's controls and how to use the chain saw properly. Failure to follow instructions could lead to personal injury. If you have any questions or problems, please contact your ECHO dealer. Physical condition Do not operate a chain saw when you are fatigued or under the influence of alcohol or drugs.
Fuel DANGER Petrol and fuel are extremely flammable. If spilled or ignited by ignition source, it can cause fire and serious injury or property damage. Extreme caution is required when handling petrol or fuel. After refuelling, tighten fuel cap firmly and check for leakage. In case of fuel leakage, repair before starting operation since there is a danger of fire. 1. Oil tank cap 2. Fuel tank cap A: Tightening direction Use an appropriate type of fuel container.
2. Kickback safety precautions DANGER Kickback safety precaution for chain saw users: 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. In some cases, tip contact may cause a lightning-fast reverse reaction, kicking the guide bar up and back toward the operator (this is called a rotational kickback).
3. Other safety precautions Vibration and cold It is believed that a condition called Raynaud's Phenomenon, which affects the fingers of certain individuals, may be brought about by exposure to cold and vibration. Accordingly, your ECHO chain saw has shock mounts designed to reduce the intensity of vibration received through the handles. Exposure to cold and vibration may cause tingling and burning followed by loss of colour and numbness in the fingers.
Machine conditions WARNING Do not modify a chain saw in any way. Only attachments and parts supplied by ECHO or expressly approved by ECHO for use with the specific ECHO chain saw models are authorized. Although certain unauthorized attachments are useable with the ECHO powerhead, their use may, in fact, be extremely dangerous. Do not operate a chain saw that is damaged, improperly adjusted, or not completely and securely assembled. Do not operate the chain saw with a loose or defective silencer.
Description 1. Silencer - The silencer controls the exhaust noise and prevents hot, glowing particles of carbon from leaving the silencer. 2. Front hand guard - Guard between the front handle and the saw chain for protecting the hand from injuries and aiding in control of the chain saw if the hand slips off the handle. This guard is used to activate the chain brake which is to stop the saw chain rotation. 3.
Assembly Mounting guide bar and chain WARNING For your own safety, always stop the engine before performing any of the following operations. CAUTION 1. All adjustments should be made cold. 2. Always wear gloves when working on chain. 3. Do not operate with a loose chain. NOTE Move the chain brake lever (Front hand guard) fully rearward to remove or install the clutch cover to the chain saw. 1. Release chain brake 2. Two nuts 3. Clutch cover Install guide bar and chain as follows.
Operation Fuel and lubricant CAUTION Whenever opening up the fuel tank, always loosen the cap very slowly and wait for the tank pressure to be equalized before removing the cap. Fuel is a mixture of regular grade petrol and an air-cooled 2-stroke engine oil of reputable brand name. Minimum 89 Octane unleaded petrol is recommended. Do not use fuel containing methyl alcohol or more than 10 % of ethyl alcohol.
Starting the cold engine WARNING After choke control knob is pulled and then knob is returned to original position, throttle remains a little open (latch condition). If engine is started in this latch condition, chain starts to turn. Do not start engine before chain brake is activated. CAUTION 1. After starting the engine, immediately squeeze and release throttle trigger for disengaging throttle latch and returning engine to idle, and pull front hand guard towards the operator immediately.
Starting the warm engine 1. Chain brake ACTIVATED position Confirm there is fuel and chain oil in the tanks. Press hand guard forward. (Chain brake ACTIVATED position) Lift ignition switch up. Securely hold the chain saw. Pull starter handle. Choke may be used if necessary, but after first firing sound pull throttle trigger a little to release throttle latch and choke.
Stopping the engine NOTE If engine does not stop, pull choke control knob all the way out to stop engine. Return the unit to your authorized ECHO dealer to check and repair ignition switch before starting the engine again. 1. Throttle trigger 2. Ignition switch Release throttle trigger and allow engine to idle. Push ignition switch down. Checking chain tension WARNING Make sure that the engine is shut off when checking chain tension.
Correct use of chain brake DANGER Kickback motion is very hazardous. If the tip of the bar touches wood or the like, the guide bar kicks back in an instant. The chain brake reduces the possibility of injury due to kickback. Always check that chain brake works properly before use. NOTE For practice, while cutting a small tree, push the front guard forward to engage the brake. At all times, confirm whether the brake works properly before each task.
Checking the brake function of the brake 1. Place the chain saw on the ground. 2. Hold the handle with both hands and accelerate the engine to high speed by using the throttle trigger. 3. Operate the chain brake by turning your left wrist against the front hand guard whilst gripping the front handle. 4. The chain stop immediately. 5. Release the throttle trigger. If the chain does not stop immediately, take the saw to your ECHO dealer to repair.
Cutting instruction DANGER Do not let the nose or tip of the guide bar touch anything while engine is running to avoid kickback. General In all circumstances the operation of the chain saw is a one-man job. It is difficult at times to take care of 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.
Felling a 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 CAUTION Don't saw above chest height. Limbing a fallen tree is much the same as bucking. Never remove a limb from a tree while it is supporting your weight. Be careful of the tip touching other limbs. Always use both hands. Don't cut with the saw overhead or the bar in a vertical position. If the saw should kickback, you may not have good enough control to prevent possible injury. Know how limb is stressed 1. Leave supporting limbs till last. 2. Slide support logs under trunk.
Tension and compression in timber WARNING Never use throttle latch for cutting jobs. CAUTION If you have misjudged the effects of tension and compression, and cut from the wrong side, the timber will pinch the guide bar and chain, trapping it. Racing the engine with the chain jammed will burn out your clutch. If the chain should become jammed and the saw can not be removed from the cut do not force it out. Stop the saw, force a wedge into the cut to open it up. Never force the saw when it is jammed.

Saw chain maintenance WARNING Switch off the engine before sharpening the chain. Always wear gloves when working on chain. CAUTION The following faults will increase the risk of kickback considerably. 1) Top plate angle too large 2) File diameter too small 3) Depth gauge too large NOTE These angles are referred to as Oregon 91VXL saw chain. For other branded saw chain, follow it's chain manufacturer's instruction. Properly filed cutters are shown below.
Sharpening In order to file the chain correctly you need: round file and file holder, flat file and a depth gauge tool. By using the correct file size (4.0 mm Round file) and a file holder, it is easier to receive a good result. Consult your ECHO dealer for correct sharpening tools and sizes. 1. Lock the chain - push the front hand guard forward. To rotate the chain - pull the front hand guard against front handle. 2. Your chain will have alternative left and right hand cutters.
