When checking the operation of the automatic chain
brake, use a soft surface substance like wood to
provide the impact so the chain is not damaged.
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.

improperly adjusted, or not completely and securely
assembled. Be sure that the saw chain stops
