RULES FOR SAFE OPERATION  
A. Kickback Safety Precautions for Chain Saw Users  
WARNING!  
1.With a basic understanding of kickback,  
you can reduce or eliminate the element of  
surprise.  
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.  
Sudden surprise contributes to accidents.  
Tip contact in some cases may cause a light-  
ning 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.  
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.  
The Kick Guard® device is not installed on the  
guide bar when you purchase your ECHO chain  
saw.  
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.  
The Kick Guard® can be used in a majority of  
cutting operations, and is especially recom-  
mended for beginners, homeowners, or chain  
saw novices.  
Most cutting operations can be accomplished  
4.Cut at high engine speeds.  
with the Kick Guard® in place.  
5.Do not overreach or cut above shoulder  
height.  
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.  
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.

3.Use safety footwear, snug-fitting clothing  
and protective gloves. Wear eye, hearing,  
and head protection devices.  
14.Keep the handles dry, clean, and free of oil  
or fuel mixture.  
4.Use caution when handling fuel. Move the  
chain saw at least 3 m (10 feet) from the  
fueling point before starting the engine.  
15.Operate the chain saw only in well ventilated  
areas.  
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.  
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.  
6.Do not start cutting until you have a clear  
work area, secure footing, and a planned  
retreat path from the falling tree.  
(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.)  
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.  
When carrying a chain saw with the engine  
running, push the front hand guard forward  
to engage the chain brake.  
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.  
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.
