RULES FOR SAFE OPERATION
A. Kickback Safety Precautions for Chain Saw Users
WARNING!
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 .
The Kick Guard ® device is not installed on the
guide bar when you purchase your ECHO chain
saw. The Kick 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 Kick Guard® in place.
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 .
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.
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, or the
equivalent, specified by the manufacturer.
B. Other Safety Precautions
1. Do not operate a chain saw with one hand! Serious injury to the operator, helpers, byst anders, 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; protective gloves; and eye, hearing and head protection devices. Wear protective hair covering
to contain long hair .

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.
2
7. Keep all parts of your body away from the saw
chain when the engine is running.
14.Keep the handles dry , clean, and free of oil or
fuel mixture.
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.
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 the items listed
in the Instruction Manual maintenance instructions, should be performed by competent chain
saw 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.S park arrestor mufflers approved to SAE Standard J335b 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.
WARNING
• 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
muffler.
• Always keep exhaust area clear of flammable debris during transportation or when storing,
otherwise serious property damage or personal injury may result.
W ARNING
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 unit.
• NEVER reach into any opening while the engine is running. Moving parts may not be visible through openings.
WARNING
Using improper replacement components or removing safety devices may result in serious or fatal injury .
