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 the items
listed in the Instruction Manual maintenance
instructions, should be performed by compe-
tent chain saw service personnel. (For ex-
ample, 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. Spark 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.
