S This saw is equipped with a chain brake.
The brake is designed to stop the chain if
kickback occurs.
S Practice cutting a few small logs using the
following techniques to get the“feel” ofus-
ing your saw before you begin a major
sawing operation.
S The
inertia--activated chain brake is
activated if the front hand guard is pushed
forward, either manually (by hand) or
automatically (by sudden movement).

disengaged by pulling the front hand guard
back toward the front handle as far as

S Cut wood only. Do not cut metal, plastics,
masonry, non-wood building materials, etc.

object. Inspect the saw and repair or re-
place parts as necessary. If the chain

Look for decay and rot. If thetrunk is rotted,
it can snap and fall toward the

Check for broken or dead branches which
can fall on you while cutting.
Make sure there is enough room for the treeto
fall. Maintain a distance of 2-1/2 tree lengths
from the nearest person or other objects. En-
gine noise can drown out a warning call.
