OPERATING TIPS
S Check chain tension before first use and
after 1 minute of operation. See CHAIN
TENSION in the ASSEMBLY section.
S Cut wood only. Do not cut metal, plastics,
masonry , n on-wood building m ateria ls, etc.
S Stop the saw if the chain strikes a foreign
object. Inspect the saw and repair or re-
place parts as necessary.
S Keep the chain out of dirt and sand. Even a
small amount of dirt will quickly dull a chain
and th us in crease thepossibility 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 m ajor
sawing operation.
S Squeeze the throttle trigger and allow the
engine to reach full speed before cutting.
S Begin cutting with the saw f rame
against the log.
S Keep theengine at full speed the entire
time you are cutting.
S Allowthechaintocutfor you.Exert only
light downward pressure. If you force
the cut,damage tothe bar,chain, oren-
gine can result.
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 withouta cutting load,unneces-
sary wear can occur to the chain, bar,
and engine. It is recommended that
the engine not be operated for lon-
ger than 30 seconds at full throttle.
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 after cutting.
TREE FELLING TECHNIQUES
WARNING: Check for broken or dead
branches which can fall while cutting causing
serious injury. Do not cut n ear buildings 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 b ad 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.
S Carefully planyour sawingoperation inad-
vance.
S Clear t hework area. You needa cleararea
all aroundthetree so youcan have secure
footing.
S The chain saw operator should keep on
the uphill side of the terrain as the tree is
likely torollor slidedownhill afterit isfelled.
S Study the natura l condi tions 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.
S The lean of the tree. The lean of a tree
might not be apparent due to uneven or
sloping terrain. Use aplumb or lev el tode-
termine the direction of tree lea n.
S Weight and branches on on e side.
S 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 i s enough room for the tree t o
fall. M aintain a distance o f
2-1/2 t ree 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, andwire fromthe treewherecuts areto
be made.

onal to the line of fall.

FELLING LARGE TREES
(6 inches (15 cm) in diameter or larger)
The notch method is used to fell large trees.
A not chis cut onthe sideof thetreein t hede-
sired direction of f all. After a felling cut i s
made on the opposite side of tree, the tree
will tend to fall into the notch.
NOTE: If the tree has large buttress roots,
removethem beforemaking thenotch. If us-
ing saw to remove buttress roots, keep saw
chain fromcontactingground topreventdull-
ing of the chain.
NOTCH CUT AND FELLING THE
TREE
S Make notch cut by cutting the top of the
notch first. Cut through
1/3 of the diameter
ofthetree. N extcompletethe notchby cut-
ting the bottom of the notch. See illustra-
tion. Once the notch is cut remove the
notch of wood from the tree.

Second cut
Final (felling) cut here, 2 inches
(5 cm) above center of notch.
Hinge
S After removing the wood from the notch,
make the felling cut on the opposite side of
the n otch. This is doneby makinga cut abou t
two inches (5 cm) higher than the center of
the notch. This will leave e nough uncut wood
between the felling cut and the notch to form
a hinge. This h inge will help prevent the t ree
from falling in the wrong direction.
