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 , non-wood building materia ls, e tc.
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
andthus increase the possibility of kickback.
S Practice cutting a few smalllogs 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 engineat full speed the entire
time you are cutting.
S Allowthechaintocutforyou. Exertonly
light downward pressure. If you force
thecut,damage tothebar,chain, oren-
gine can result.
S Release t he 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.

TREE FELLING TECHNIQUES
WARNING: Check for broken or
dead branches which can fall while cutting
causingserious injury. Do notcut nearbuild-
ings or electricalwires ifyou donot know the
directionof treefall, norcutatnight sinceyou
will not be ale to see well, nor during bad
weather such as rain, snow,or strongwinds,
etc. If the treemakes contact with any utility
line, the utility company should be notified
immediately .
S Carefullyplanyour sawingoperationinad-
vance.
S Cleartheworkarea. Youneedacleararea
allaround thetree so you can havesecure
footing.
S The chain saw operat or should keep on
the uphill side of the terrain as the tree i s
likely torollorslidedownhillafterit isfelled.
S Study the natural cond itio ns th at 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. Usea plumbor level tode-
termine the direction of tree lean.
S Weight and branches on o n e side.
S Surrounding trees and obstacles.
Look for decay and rot. If thetrunk is rotted,
it can snap and fall t oward the operator.
Check for broken or dead branches which
can f all on you while cutting.
Make sure there is enough room for the tree to
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, andwire fromthe treewherecuts areto

FELLING LARGE TREES
(6 inches (15 cm) in diameter or larger)
The notch method is used to fell large trees.
Anotchis cutonthe side ofthetreeinthede-
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.
NOTE: If the tree has large buttress roots,
removethembefore makingthenotch. I fus-
ing saw to remove buttress roots, keep saw
chain fromcontacting groundtopreventdull-
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. Nextcomplete thenotch bycut-
ting the bottom of the notch. See illustra-
tion. Once the notch is cut remove t he
notch of wood from the tree.

(5 cm) above center of notch.
Hinge
S After removing the wood from the notch,
make the felling cut on the opposite side of
thenotch. This isdone by makinga cutabout
two inches (5 cm) higher than the center of
the notch. This willleave e nough uncutwood
between the felling cut and the notch to form
a hinge. This hinge will helpprevent the tree
from falling in the wrong direction.
