OPERATING TIPS
Look for decay and rot. If thetrunk is rotted,
it can snap and fall toward the operator.
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 materials, etc.
S Stop the saw if the chain strikes a foreign
object. Inspect the saw and repair or re-
place parts as necessary.
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
be made.
S Keep the chain out of dirt and sand. Even a
small amount of dirt will quickly dull a chain
andthus increasethepossibility ofkickback.
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.

onal to the line of fall.

Release the throttle trigger as soon as
the cut is completed, allowing the en-
gine to idle. If you run the saw at full
throttlewithoutacuttingload,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.
To avoid losing control when cut is com-
plete, do not put pressure on saw at end
of cut.
The notch method is used to fell large trees.

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 1/3 of the diameter

ting the bottom of the notch. See illustra-
tion. Once the notch is cut remove the
notch of wood from the tree.

S Stop the engine before setting the saw
down after cutting.
TREE FELLING TECHNIQUES
WARNING: Check forbrokenordead
branches which can fall while cutting causing
serious injury. Do not cut near buildings or
electrical wires if you do not know the direction
of tree fall, nor cut at night since you will not be
aletoseewell,nor duringbadweather suchas
rain, snow, or strong winds, etc. If the tree
makes contact with any utility line, the utility
company should be notified immediately.
