SAFETY
Rules for Safe Operation
Kickback Safety Precautions 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.
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.
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 specified by the manufacturer or
the equivalent.
Correct Use of Chain Brake
Chain Brake Operation
• 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.
Testing the Brake
• 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 dealer for repair.
Note:
• 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 while the chain brake is locked.
Do not use a a bar and chain combination other than those specified in this
manual.
For your own safety, do not remove the chain brake system.
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.
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
Canada: CSA Standard Z62.1, Z62.3
SAFETY CS-7310PW
8 X7503340600
© 12/20 ECHO Incorporated
ANSI Standard B175.1 and CSA
Z62.1.3 stipulate 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 Standards B175.1 and CSA
Z62.1.3.
Automatic Chain Brake
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.
2. Hold the saw with the guide bar approximately 35 cm (14 inches) 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 devices.
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. A spark arrestor muffler approved to SAE Standard J335 is standard on
this chain saw 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.
20. When using a chain saw a fire extinguisher should be available.
21. When felling, keep at least 2 tree lengths between yourself and your
fellow workers.
22. Follow instructions in your operator’s manual for starting the chain saw.
23. Never adjust the guide bar or saw chain when the engine operating.
24. When boring with the chain saw, the initial cut should be introduced
with the lower part of the nose (tip) until the hole is sufficiently large so
as to introduce the entire nose (tip) of the guide bar. This technique
should reduce the danger of kickback.
25. Allow your chain saw to cool before refueling, and do not smoke while
refueling.
Chain saws shall be used in accordance with the operating
instructions and safety precautions listed in the operator's
manual(s). It shall be the responsibility of the owner to see that
such instructions and precautions are given to every operator
who uses the saw.
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.
