IMPORTANT SAFETY WARNINGS  
DANGER!  
Kickback hazard. Do not allow guide bar tip to contact objects. Allowing an unguarded  
guide bar tip to touch any object during cutting may cause the guide bar to suddenly kick  
up and back toward the operator, a forceful reaction called rotational kickback. Body  
contact with a moving saw chain will cause serious or fatal injury.  
DANGER!  
Prevent hazardous Rotational Kickback! Install the Echo Kick Guard® anti-kickback bar tip  
guard in cutting applications where bar tip contact with solid objects or surfaces cannot  
be avoided.

KEY CHAIN SAW TERMS See Glossary at back for additional terms.  
KICK GUARD® DEVICE - The ECHO brand name for its  
anti-kickback bar tip guard.  
BALLISTIC - A special material used in protection devices  
designed to reduce the risk of penetration from chain contact.  
BINDING - Closing of the cut or shifting of the wood, possibly  
trapping the saw blade in the cut. Binding includes pinching.  
(Also, see PINCH.)  
PINCH - Specifically the closing-in of the wood which  
pinches and stops the chain along the top rails of the guide bar  
during a cut. This can result in the chain saw being propelled  
straight back toward the operator (called a Linear Kickback).  
Pinch can also occur on the lower rails of the bar, resulting in  
the chain saw being pulled away from the operator.  
CHAIN CATCHER - A projection designed to reduce the risk of  
the operator’s right hand from being hit by a chain, which has  
broken or derailed from the guide bar during cutting.  
PUSH AND PULL - When cutting is done along the bottom rails  
of the guide bar, the reaction on the saw is to pull away from the  
operator. When the top of the guide bar is used, the reaction  
pushes the saw towards the operator. Both are normal reactions  
which must be controlled by the operator.  
CHAIN TENSIONER - The device which permits precise  
adjustment of the chain tension.  
CHAPS - Specially designed leg protection, which can reduce  
the risk of injury due to contact with a moving saw chain.  
REDUCED-KICKBACK GUIDE BAR - Guide bars which are  
recognized by the ANSI Standard B175.1 as having as small or  
reduced radius nose to reduce the potential kickback area.  
FOLLOW THROUGH - After the chain saw completes a cut and  
is no longer supported by the wood, an uncontrolled chain saw  
can continue on its path and strike the legs, feet or body of the  
operator.  
LOW, or REDUCED-KICKBACK SAW CHAIN - Saw chain  
which has been demonstrated to reduce kickback on a selected  
group of chain saw models during ANSI testing. Before using  
“reduced kickback” chain, ask your ECHO dealer to determine  
if your chain saw can accommodate “reduced-kickback” chain  
and still meet the 45-degree CKArequirement explained on page  
13.  
FRONT HAND GUARD - This required device is intended  
to reduce the operator’s risk of injury from projecting  
branches and saw-chain contact with the left hand in the  
event the operator loses his grip from the upper part of the  
handle.  
GUIDE BAR - The grooved bar that supports and guides the  
saw chain.  
SKATING - When the chain saw fails to dig in during a cut, the  
guide bar can begin hopping or dangerously skidding along the  
surface of the log or branch, possibly resulting in the loss of  
control of the chain saw. To prevent or reduce skating, hold the  
chain saw with two hands and make sure the saw chain  
establishes a groove for cutting.  
KERF - The grooved cut produced by the saw chain cutters.  
KICKBACK - The general term describing rotational and linear  
kickback, two highly dangerous reactions which can occur when  
operating a chain saw. When used alone in this manual, the  
term “kickback” refers to rotational kickback. To prevent  
kickback, keep the bar nose properly covered with the Kick  
THROTTLE TRIGGER - Located in the rear handle, it is used  
to control the speed of the engine.  
Guard® device. If the Kick Guard® device is absent, kickback  
can occur if the unshielded bar nose touches an object or the  
ground.  
THROTTLE TRIGGER LATCH BUTTON - The control used on  
some chain saws to set the throttle for a fast idle speed, which  
may be required to start a cold engine. The throttle can be  
unlatched by squeezing and releasing the throttle trigger.  
ROTATIONAL KICKBACK - The violent reaction which can  
occur when the chain at the upper section of the nose is suddenly  
stopped or impeded, thereby dangerously driving the bar nose  
in an upward arc toward the operator.  
THROTTLE TRIGGER LOCKOUT LEVER - A safety lever on  
the top of the top/rear handle which must be depressed before  
the throttle trigger can be activated. When the operator lets go  
of the top/rear handle, the throttle will be locked in idle position.  
LINEAR KICKBACK - A push reaction, which can  
occur under certain conditions with the guide bar buried in the  
cut when the cut closes, pinching the chain along the top rails  
of the guide bar and propelling the chain saw straight back  
toward the operator.

INTRODUCTION  
WARNING!  
Before using your saw, read this Safety Manual and your chain saw instruction manual carefully. You  
must completely understand and follow all safety rules, precautions, and operating instructions.  
Echo recommends that you obtain and review the supplemental ECHO Chain Saw Safety Video.  
Congratulations on taking the right steps to learn basic chain saw safety. Over the years, Echo has developed and  
improved technology to increase the safety of chain saw use. However, chain saws are powerful cutting tools intended  
to quickly cut trees and branches and to get the job done fast. Like other types of outdoor cutting and wood working  
power equipment, the chain saw’s sharp, high-speed cutters require that you operate the saw carefully to avoid serious  
or fatal injury.  
You must read and understand the specific chain saw instruction manual, the Kick Guard® instructions and this safety  
manual. Before operating your gasoline or electric chain saw, you must learn about the chain saw reactions, which can  
occur when cutting. Unless noted, the safety rules presented apply to both gasoline and electric chain saws.  
This manual describes the hazards and risks associated with cutting, trimming, felling, refueling and other activities  
involving use of a chain saw. Many vital safety awareness tips are mentioned to help identify the dangers of using chain  
saws, and to teach you the precautions to take to avoid injury. ECHO has also provided helpful information about cutting  
techniques to make the tasks easier, more productive, and safer.  
If you have any feelings that the tree removal or cutting task requires you to put yourself, your property, or others at risk,  
please consider calling a professional to handle the job. Tree trimming and felling mishaps can cause serious or fatal  
injury to you, others, and possible damage to property.  
If you need a copy of a chain saw safety or instruction manual, have product questions, are unsure about the safe use  
or maintenance of your saw, or would like to obtain a chain saw safety video, please visit our website at http://www.echo-  
usa.com. You may also contact your local ECHO dealer, or contact ECHO directly at (800) 432-3246. The chain saw  
safety video provides operational safety information and cutting demonstrations.

FORCES YOU MUST CONTROL  
This section explains the forces which must be controlled to avoid injury  
when operating either a gas or electric-powered chain saw. Always remem-  
ber that your best defenses are to exercise caution and use the chain saw  
properly, and to be prepared to react to these forces  
PULL  
PULL, PUSH and KICKBACK are terms for the direction a reaction takes.  
CUTTING ON BOTTOM OF GUIDE-  
BAR PULLS SAW AWAY FROM YOU  
PULL - When you are cutting on top of a log with the lower portion of the  
chain moving toward you, the chain saw will be pulled into the wood and  
away from you.  
PUSH - Cutting on the underside of a log pushes the chain saw toward you.  
PUSH  
CUTTING ON TOP OF GUIDE-BAR  
PUSHES SAW TOWARD YOU  
WOOD  
PUSH and PULL forces are controlled by anticipating which reaction will  
happen and adjusting your position and stance to compensate.  
FORCE  
REACTION  
ROTATIONAL KICKBACK - When the chain is moving downward around the  
upper nose of the bar, solid contact there may drive the bar tip upward in an  
arc toward you. This is an extremely dangerous reaction called Rotational  
Kickback. When used alone in this manual, the term kickback will always  
refer to the rotational kickback.  
Ro
Chain moving downward at impact  
Rotational kickback is predictable, preventable and controllable. If the  
operator is not alert to the possibility of a kickback, it may come as a  
complete surprise. The possibility of kickback can be greatest if the chain is  
not a low- or reduced kickback type, or if the bar is not a reduced-kickback  
type. The best defense against rotational kickback is making sure the chain  
does not contact anything solid at the upper nose of the bar. This can be  
assured by proper installation of the Kick Guard ® device.  
ROTATIONAL KICKBACK  
PINCH  
LINEAR KICKBACK - A sudden PUSH reaction that occurs when the chain  
along the top rails of the bar gets pinched in a cut. This type of reaction  
pushes the chain saw straight back toward the operator. The Kick Guard ®  
device on your bar nose acts as a stop against this type of kickback by  
stopping the guide bar.

FORCES YOU MUST CONTROL  
FORCE OF GRAVITY & “FOLLOW THROUGH” – Gravity is always present and  
you must be prepared for it when you are operating a chain saw. During the  
cutting operation, the weight of the chain saw is supported by the material being  
cut. When the saw completes the cut, the saw is no longer supported, and the  
operator must control both the weight and the downward momentum of the saw.  
Never reach too far out with the saw. If you reach too far out with the saw, you  
may be unable to control it. Maintain a proper grip, a balanced stance, and good  
footing. Never cut when you are off balance – the sudden burden of supporting  
the weight of the saw could cause you to fall or lose control of the saw. Make no  
cuts above chest height where control may be more difficult.  
DO NOT OVER -REACH TO  
MAKE A CUT  
IMPORTANT: When you’re about to complete a cut on an elevated tree branch or  
limb, be ready to release the throttle and support the chain saw so that the guide  
bar and moving chain will not “follow through” and cut into your legs, feet, or body  
after the guide bar breaks into the clear.  
SKATING - This condition occurs when the saw chain does not dig in properly  
when starting a cut, and does not start a defined groove as it attempts to  
penetrate the wood. The guide bar then begins “hopping” or skidding side-to-side  
along the surface. When this occurs, you do not have full control of the chain  
saw, and the bar nose could strike something and cause a kickback. If you are  
holding the chain saw with one hand and a branch with the other, the chain saw  
could skate laterally into your hand holding the branch. To prevent or reduce  
skating, always hold the chain saw with two hands, and make sure the saw chain  
has established a groove for cutting. For gasoline-powered units, throttling down  
the chain speed may help the chain get grooved, but once the chain is grooved,  
throttle up the chain speed to complete the cut.  
BEWARE OF SKATING

KICK GUARD® INSTALLATION  
DANGER!  
Chain saw kickback is an extremely dangerous reaction. Kickback can cause serious, or fatal  
injuries!  
Kick Guard®  
KICK GUARDANTI-KICKBACK BAR TIP GUARD: This is an anti-kickback device that covers  
the bar nose to prevent chain contact at the kickback-generating area of the nose. The ECHO bar  
tip guard is called the Kick Guard ® device. With the device properly mounted on the bar nose,  
rotational kickback cannot occur. The device will also halt linear kickback. (See definitions of rotational  
and linear kickback.)  
The Kick Guard ® device is not installed on the guide bar when you purchase your ECHO chain saw. It is the  
operator’s responsibility to decide upon the safest cutting approach for the job being done. If you think the Kick Guard®  
limits or obstructs the cutting operation and you decide to use the saw without the guard, it is your responsibility to know  
how to operate the saw safely. This manual provides safety information to operate with and without the Kick Guard® .  
The Kick Guard ® can be used in a majority of cutting operations, and is especially recommended for beginners,  
homeowners, or chain saw novices. However, it is designed to be removable to allow the saw to be used without the  
device. Use of the saw without the Kick Guard device requires a higher level of caution on the part of the operator. Study  
the information and precautions in this manual carefully to learn how to operate the saw safely. Contact ECHO if you  
have any questions, or if you do not understand the information.  
Kick Guard ®  
Simple to Install!  
Kick Guard ®  
Prevents  
See Installation Procedure  
in your chain saw Instruction  
Manual.  
Rotational  
Kickback!  
Use the Kick Guard ® in cutting applications where the bar’s tip may come into contact with solid objects or  
surfaces. Most cutting operations can be accomplished with the Kick Guard® in place.  
ECHO HIGHLY RECOMMENDS the use of the Kick Guard ® Device:  
1. If you are a beginner or novice chain saw user.  
2. If you are cutting in or around adjacent brush, small saplings, trees, or other solid objects that can be contacted by  
the bar tip.  
3. If it is possible that the tip of the saw may come in contact with an adjacent object such as a log, other trees,  
branches, root, stump, fence, post, wall, rocks, nails etc.  
4. If you can’t see the tip of the saw and it may come in contact with another object, such as in a log pile, brushy area,  
or dense leafy area.  
5. If you are limbing a tree and can’t see the tip due to leaves or other debris blocking the view.  
6. If you have any concern that the cutting you will be doing may have an increased risk of tip contact.

CONDITIONS WHICH MAY REQUIRE REMOVAL OF KICK GUARD®  
In any circumstance, it is your responsibility to learn how to minimize the risk of kickback if you are using the  
saw without the Kick Guard in place.  
Even if you have prior experience with safe chain saw operation, or are trained in the prevention of kickback, please  
use extreme caution if you choose not to install the tip guard, or if you decide to remove it. If you plan to use the saw  
without the Kick Guard® device to facilitate cutting, refer to the section “Operating Saw Without Kick Guard® Device”.  
The Kick Guard® is ideal for most cutting applications, but it may be necessary to remove it in limited  
situations such as:  
1. Felling trees that are larger in diameter than the working length of  
the guide bar.  
2. Cutting trees and logs that are larger in diameter than the  
effective cutting length of the bar (dimension from engine to the  
inside of the Kick Guard ®).  
3. To remove a bound saw out from a cut log.  
4. To draw the bar nose through a cut.  
5. Making a boring cut into a log or tree. (Professional Users

6. To remove a saw when a wedge is being used.  
Echo has incorporated additional technology to help minimize the risk of kickback, such as reduced kickback chain,  
reduced kickback guide bar, and the chain brake system. These other devices only reduce kick back forces, and do not  
guarantee the prevention of kickback or kickback injuries. Only a properly installed kick guard absolutely prevents  
all rotational kick back.  
If you use the saw without the Kick Guard, you can prevent injury from kickback by: avoiding contact with solid  
objects at the upper tip of the guide bar; properly positioning yourself out of the line of the guide bar; and using  
a firm, two-handed grip. It is solely your responsibility to take these precautions.  
Prevent Rotational Kickback!
