CHAIN BRAKE
WARNING:
Ensure chain brake is
disengaged by pulling the front hand guard
back toward the front handle as far as possible.
The chain brake must be disengaged before
cutting with the saw.
S This saw is equipped with a chain brake.
The brake is designed to stop the chain if
kickback occurs.
S The inertia activated chain brake is activated
if the front hand guard is pushed forward, ei-
ther manually or by centrifugal force.
S If the brake is already activated, it is disen-
gaged by pulling the front hand guard back
toward the front handle as far as possible.
S When cutting with the saw, the chain brake
must be disengaged.

IMPORTANT POINTS

WARNING:
Sometimes wood chips
get stuck in the clutch cover causing the chain
to jam. Always stop the engine before cleaning.
S Check chain tension before first use and af-
ter 1 minute of operation. See CHAIN TEN-
SION in the ASSEMBLY section.
S Cut wood only. Do not cut metal, plastics,
masonry, non-wood building materials, etc.
S The bumper spike may be used as a pivot
when making a cut.
S Stop the saw if the chain strikes a foreign
object. Inspect the saw and repair parts as
necessary.
S Keep the chain out of dirt and sand. Even a
small amount of dirt will quickly dull a chain
and increase the possibility of kickback.
S Practice cutting a few small logs using the
following techniques to get the "feel" of us-
ing your saw before you begin a major
sawing operation.
S Squeeze the throttle trigger and allow the
engine to reach full speed before cutting.
S Begin cutting with the saw frame
against the log.
S Keep the engine at full speed the entire
time you are cutting.
S Allow the chain to cut for you. Exert only
light downward pressure.
S Release the throttle trigger as soon as
the cut is completed, allowing the en-
gine to idle. If you run the saw at full
throttle without a cutting load, unneces-
sary wear can occur.
S To avoid losing control when cut is com-
plete, do not put pressure on saw at end
of cut.
S Stop the engine before setting the saw down.

TREE FELLING TECHNIQUES
WARNING:
Felling a tree requires
chain saw skills and experience. Inexperi-
enced users should not fell trees. Do not at-
tempt any task that makes you feel uncom-
fortable or unsure.
WARNING:
Do not cut near buildings
or electrical wires if you do not know the direc-
tion of tree fall, at night since you will not be able
to see well, or during bad weather such as rain,
snow, or strong winds. as fall is unpredictable.
Carefully plan your sawing operation in ad-
vance. You need a clear area all around the
tree so you can have secure footing. Check
for broken or dead branches which can fall
on you causing serious injury.
Natural conditions that can cause a tree to
fall in a particular direction include:
S The wind direction and speed.
S The lean of the tree. The lean of a tree
might not be apparent due to uneven or
sloping terrain. Use a plumb or level to de-
termine the direction of tree lean.
S Weight and branches on one side.
S Surrounding trees and obstacles.
Look for decay and rot. If the trunk is rotted, it
can snap and fall toward the operator. Make
sure there is enough room for the tree to fall.
Maintain a distance of
the nearest person or other objects. Engine
noise can drown out a warning call. Remove
dirt, stones, loose bark, nails, staples, and wire
from the tree where cuts are to be made.
Plan a clear retreat path

FELLING LARGE TREES
(15 cm in diameter or larger)
The notch method is used to fell large trees.
A notch is cut on the side of the tree in the de-
sired direction of fall. After a felling cut is
made on the opposite side of tree, the tree
will tend to fall into the notch.
NOTCH CUT AND FELLING THE
TREE
S Make notch cut by cutting the top of the
notch first. Cut through
of the tree. Next complete the notch by cut-
ting the bottom of the notch. See illustra-
tion. Once the notch is cut remove the
notch of wood from the tree.
