IMPORTANTPOINTS
• Check chain tension before first use and
after f minute of operation. See CHAIN
TENSION Lnthe ASSEMBLY section
• Cut wood only. Do not cut metal, plastics,
masonry, non-wood building materials, etc.
• Stop the saw ff the chain strikes a foreign
object. Lnspect the saw and repair or re-
place parts as necessary.
• Keep the chain out of dirt and sand Even a
small amount of dirt will quickly dult a chain
and thus increase the possibil*ty of kickback.
• Practice cutting a few small logs using the
foIIowing techniques to get the "feeF of us-
ing your saw before you begin a major
sawing operation.
• Squeeze the throftle trigger and allow
the engine to reach full speed before
cutting.
• Begin cutting with the saw frame
against the log.
• Keep the engine at full speed the entire
time you are cutting.
• ALlow the chain to cut for you. Exert only
light downward pressure. If you force
the cut, damage to the bar, chain, or en-
gine can result.
• 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 to the chain, bar,
and engine
• To avoid tosing conttoL when cut is com-
plete, do not put pressure on saw at end
of cut.
• Stop the engine before setting the saw
down after cutting.
TREE FELLING TECHNIQUES
WARNING: Check for broken or
dead branches which can fall wMle cutting
causing serious injury. Do not cut near build-
ings or etecthcal wires if you do not know the
direction of tree fall, nor cut at night since you
will not be ale to see welt, 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
immediately.
• CarefuLly plan your sawing operation in ad-
vance.
• Cleartheworkarea Youneedacleararea
alI around the tree so you can have secure
footing.
• The chain saw operator should keep on
the uphLtl side of the terrain as the tree is
likely to rolI or slide downhill after it is relied.
• Study the naturat conditions that can cause
the tree to falI in a particular direction.
Natural conditions that can cause a tree to
falI in a particular direction include:
• The wind direction and speed.
• 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 dLrection of tree Lean.
• Weight and branches on one side.
• Surrounding trees and obstacles
Look for decay and rot. if the trunk 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 tree
to fail. Maintain a distance of 2 1/2 tree
lengths from the nearest person or other ob-
jects 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 to
the rear and diagonal to the line of fall.

FELLtNG LARGE TREES
(6 inches (t5 cm) in diameter or Iarger)
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 fal_ After a felling cut is
made on the opposite side of tree, the tree
will tend to fall into the notch
NOTE: If the tree has large buttress roots,
remove them before making the notch, ff us-
ing saw to remove buttress roots, keep saw
chain from contacting ground to prevent dull-
ing of the chain.
NOTCH CUT AND FELLING THE
TREE
• Make notch cut by cutting the top of the
notch first. Cut through 1/3 of the diameter
of the tree. Next complete the notch by cut-
ting the bottom of the notch. See i_lustta-
tion. Once the notch is cut remove the
notch of wood from the tree
Final (felling) cut here, 2 inches
(5 cm) above center of notch

Second cut
• After removing the wood from the notch,
make the felling cut on the opposite side of
the notch. This is done by making a cut about
two inches (5 cm) higher than the center of
the notch. This will leave enough uncut wood
between the felling cut and the notch to form
a hinge. This hinge will help prevent the tree
from fal_ing in the wrong direction
