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 to-
ward 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 the items listed
in the Instruction Manual maintenance instruc-
tions, should be performed by competent chain
saw service personnel. (For example, if im-
proper tools are used to remove the flywheel
or if an improper tool is used to hold the fly-
wheel 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 Stan-
dard 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 ar-
restor screen.
