Rules For Safe Operation  
Kickback Safety Precautions for Chain Saw Users  
For more information  
scan this QR code.  
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.  
Either of these reactions may cause you to lose control of the  
saw which could result in serious personal injury.  
Rotational kickback  
The tip guard device is not installed on the guide bar when you  
purchase your ECHO chain saw. The tip guard can be used in a  
majority of cutting operations, and is especially recommended  
for beginners, homeowners, or chain saw novices. Most cutting  
operations can be accomplished with the tip guard in place.  
Rotational kickback  
Do not rely exclusively upon the safety devices built into your  
saw. As a chain saw user, you should take several steps to keep  
your cutting jobs free from accident or injury.  
Chain moving downward at impact  
Kickback Danger Zone  
1. With a basic understanding of kickback, you can reduce or  
eliminate the element of surprise. Sudden surprise  
contributes to accidents.  
2. Keep a good firm grip on the saw with both hands, the right  
hand on the rear handle, and the left hand on the front  
handle, when the engine is running. Use a firm grip with  
thumbs and fingers encircling the chain saw handles. A firm  
grip will help you reduce kickback and maintain control of  
the saw. Don’t let go.  
3. Make sure that the area in which you are cutting is free from  
obstructions. Do not let the nose of the guide bar contact a  
log, branch, or any other obstruction which could be hit  
while you are operating the saw.  
Linear kickback  
4. Cut at high engine speeds.  
5. Do not overreach or cut above shoulder height.  
6. Follow manufacturer’s sharpening and maintenance  
instructions for the saw chain.  
7. Only use replacement bars and chains specified by the  
manufacturer or the equivalent.

Correct Use Of Chain Brake  
• 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.  
• 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.  
• Slowly operate the chain brake lever while holding the saw  
firmly on the ground. When the brake lever trips, the chain  
should stop. Immediately release the throttle trigger.  
Do not allow the saw to tip forward in order to avoid damage to the chain.  
If the chain does not stop immediately, return the saw to your authorized ECHO dealer for repair.  
• For practice, while cutting a small tree, push the lever forward to lock the brake.  
• Confirm that the brake works properly before each use.  
• If the chain brake is clogged with wood chips, function of the brake may deteriorate. Always keep the  
device clean.  
• Do not increase engine RPM's while the chain brake is locked.  
The installation of a chain brake may be mandatory by law or as stipulated by insurance regulations in your  
area of operation. You should inquire through local government offices, your employer or your local dealer to  
ensure that your chain saw conforms to the required safety standard.  
ECHO chain brakes have been designed and tested to comply with international safety standards as follows.  
USA: ANSI Standard B175.1 Safety Requirement for chain saws  
ANSI Standard B175.1 stipulates that the brake shall stop the chain 0.12 seconds at an engine speed  
of 13,500 r/min. It is the responsibility of the owner/operator to ensure that the brake is serviced,  
adjusted and tested strictly in accordance with the instructions as detailed here in order to ensure  
that the brake performance is maintained in compliance with the Standard B175.1.

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.  
55 cm  
(22 in.)  
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. Release the front handle and drop the end of the guide bar  
against the wooden surface.  
4. The impact should lock the chain brake.  
When checking the operation of the automatic chain brake, use  
a soft surface substance like wood to absorb the impact so the  
chain is not damaged.  
Other Safety Precautions  
1. Do not operate a chain saw with one hand! Serious injury to the operator, helpers, bystanders, or any  
combination of these persons may result from one-handed operation. A chain saw is intended for  
two-handed use.  
2. Do not operate a chain saw when you are fatigued.  
3. Use safety footwear, snug-fitting clothing and protective gloves. Wear eye, hearing, and head protection  
4. Use caution when handling fuel. Move the chain saw at least 3 m (10 feet) from the fueling point before  
starting the engine.  
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.  
6. Do not start cutting until you have a clear work area, secure footing, and a planned retreat path from the  
falling tree.  
7. Keep all parts of your body away from the saw chain when the engine is running.  
8. Before you start the engine, make sure that the saw chain is not contacting anything.  
9. Carry the chain saw with the engine stopped, the guide bar and saw chain to the rear, and the muffler  
away from your body.  
10. Do not operate a chain saw that is damaged, improperly adjusted, or not completely and securely  
assembled. Be sure that the saw chain stops moving when the throttle control trigger is released.  
11. Shut off the engine before setting the chain saw down.  
12. Use extreme caution when cutting small size brush and saplings because slender material may catch  
the saw chain and be whipped toward you or pull you off balance.  
13. When cutting a limb that is under tension, be alert for spring-back 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.  
15. Operate the chain saw only in well ventilated areas.  
16. Do not operate a chain saw in a tree unless you have been specifically trained to do so.  
17. All chain saw service, other than items listed in the Instruction manual maintenance instructions, should  
be performed by competent service personnel. (For example, if improper tools are used to remove the  
flywheel or if an improper tool is used to hold the flywheel in order to remove the clutch, structural  
damage to the flywheel could occur and could subsequently cause the flywheel to burst.)  
18. When transporting your chain saw, use the appropriate guide bar scabbard.  
19. Spark arrestor mufflers approved to SAE Standard J335 are standard on ECHO chain saws to reduce  
the possibility of forest fires. Do not operate the chain saw with a loose or defective muffler. Do not  
remove the spark arrestor screen.  
During operation, the muffler or catalytic muffler and surrounding cover become hot.  
Never suspend the saw on a lanyard with the engine running.  
Always use the saw from the right-hand side of your body – NEVER from the left side.  
Always wear proper safety clothing to protect your lower body from sharp saw chain and hot  
Always keep exhaust area clear of flammable debris during transportation or when storing,  
otherwise serious property damage or personal injury may result.  
Moving parts can amputate fingers or cause severe injuries. Keep hands, clothing and loose objects  
away from all openings.  
ALWAYS stop engine, disconnect spark plug, and make sure all moving parts have come to a  
complete stop before removing obstructions, clearing debris, or servicing unit.  
DO NOT start or operate unit unless all guards and protective covers are properly assembled to  
NEVER reach into any opening while the engine is running. Moving parts may not be visible  
through openings.  
Using improper replacement components or removing safety devices may result in serious or fatal  
Check fuel system for leaks due to fuel tank damage, especially if the unit is dropped. If damage or  
leaks are found, do not use unit, otherwise serious personal injury or property damage may occur.  
Have unit repaired by an authorized servicing dealer before using.

The ignition components of this machine generate an electromagnetic field during operation which  
may interfere with some pacemakers. To reduce the risk of serious or fatal injury, persons with  
pacemakers should consult with their physician and the pacemaker manufacturer before operating  
this machine. In the absence of such information, ECHO does not recommend the use of ECHO  
products by anyone who has a pacemaker.  
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 vibration and cold. Exposure to vibration  
and cold may cause tingling and burning sensations, 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.  
• Keep your body warm, especially the head, neck, feet, ankles,  
hands, and wrists.  
• Maintain good blood circulation by performing vigorous arm exercises during frequent work breaks, and  
also by not smoking.  
• Limit the hours of operation. Try to fill each day with jobs where operating the unit or other hand-held  
power equipment is not required.  
• If you experience discomfort, redness, and swelling of the fingers followed by whitening and loss of feeling,  
consult your physician before further exposing yourself to cold and vibration.  
Repetitive Stress Injuries  
It is believed that overusing the muscles and tendons of the  
fingers, hands, arms, and shoulders may cause soreness,  
swelling, numbness, weakness, and extreme pain in those  
areas. Certain repetitive hand activities may put you at a high  
risk for developing a Repetitive Stress Injury (RSI). An extreme  
RSI condition is Carpal Tunnel Syndrome (CTS), which could  
occur when your wrist swells and squeezes a vital nerve that  
runs through the area. Some believe that prolonged exposure to  
vibration may contribute to CTS. CTS can cause severe pain for  
months or even years.  
To reduce the risk of RSI/CTS, do the following:  
• Avoid using your wrist in a bent, extended, or twisted position. Instead try to maintain a straight wrist  
position. Also, when grasping, use your whole hand, not just the thumb and index finger.  
Take periodic breaks to minimize repetition and rest your hands.  
• Reduce the speed and force with which you do the repetitive movement.  
• Do exercise to strengthen the hand and arm muscles.  
• Immediately stop using all power equipment and consult a doctor if you feel tingling, numbness, or pain in  
the fingers, hands, wrists, or arms. The sooner RSI/CTS is diagnosed, the more likely permanent nerve  
and muscle damage can be prevented.
