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).
S If the brake is already activated, it is
disengagedby pullingthefronthandguard
back toward the front handle as far as
possible.

TREE FELLING TECHNIQUES
Place the saw on firm ground. Grip the rear
handlewithyourrighthandandthefronthan-
dle with your left hand. Apply full throttle by
fully depressing the throttle trigger. Activate
the chain brake by turning your left wrist
against the hand guard without releasing
your grip around the front handle. The chain
should stop immediately.
WARNING:
Check for broken or
dead branches which can fall while cutting
causing serious injury. Do not cut near build-
ings or electrical wires if you do not know the
direction of tree fall, nor cut at night since you
will not be ale to see well, nor during bad
weather such as rain, snow, or strong winds,
etc. If the tree makes contact with any utility
line, the utility company should be notified im-
mediately.

S Clear the work area. You need a clear area
all around the tree so you can have secure
footing.
S The chain saw operator should keep on
the uphill side of the terrain as the tree is

S Study the natural conditions that can cause
the tree to fall in a particular direction.
Natural conditions that can cause a tree to
fall in a particular direction include:
S The wind direction and speed.
WARNING:
When performing the
following procedure, the engine must be
turned off.
Grip the rear handle with your right hand and
the front handle with your left hand. Hold the
chain saw approximately 14″ (35cm) abovea
stump or other wooden surface. Release your

TENSION in the ASSEMBLY section.
S Cut wood only. Do not cut metal, plastics,
masonry, non-wood building materials, etc.
S Stop the saw if the chain strikes a foreign
object. Inspect the saw and repair or re-
place parts as necessary. If the chain
jumps off the guide bar, inspect the chain
for damageddrivelinks beforereinstalling.
Burrs on drive links, which prevent them
from entering the groove of the guide bar,
can be removed with a flat file.
S
Weight and branches on one side.
S Surrounding trees and obstacles.
Look for decay and rot. If thetrunk is rotted,
it can snap and fall toward the
operator.
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.
Remove dirt, stones, loose bark, nails, sta-
ples,andwirefromthetreewherecuts areto

and diagonal to the line of fall.
S Keep the chain out of dirt and sand. Even a

the possibility of kickback, and require chain
sharpening or replacement.
