CUTTING METHODS
IMPORTANT POINTS
S Carefully plan your sawing operation in ad-
vance.
S Clear the work area. You need a clear area
all around the tree so you can have secure
footing.
S The chain saw operator should keep on the
uphill side of the terrain as the tree is likely to
roll or slide downhill after it is felled.
S Study the natural conditions 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 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 strikesa foreignob-
ject.
Inspect the saw and repair parts as
necessary.
S Keepthechainoutofdirtandsand. Evena
small amountof dirtwill quickly dull achain
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 The wind direction and speed.
S Theleanof the tree. Thelean ofa tree might
not beapparent dueto unevenorslopingter-
rain. Use a plumb or level to determine the
direction of tree lean.
S
Squeeze the throttle trigger and allow
the engine to reach full speed before
cutting.
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. Check
for broken or dead branches which can fall 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, loosebark, nails, staples,
and wire from the tree where cuts are to be
made.

Begin cutting with the saw frame
against the log.
Keep the engine at full speed the en-
tire time you are cutting.
Allow the chain to cut for you. Exert
only light downward pressure.
Releasethethrottle triggeras soonas
the cut is completed, allowing the en-
gine to idle. If you run the saw at full
throttle without a cutting load, unnec-
essary wear can occur.
S
To avoid losing control when cut is
complete, do not put pressure on saw
at end of cut.
Plan a clear retreat path to the rear and diago-
nal to the line of fall.

Direction of Fall
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. Donotcut nearbuild-
ings or electrical wires if you donot knowthe
directionof treefall, norcut atnightsince you
will not be ale to see well, nor during bad
weathersuch as rain, snow, or strongwinds,
etc. If the tree makes contact with any utility
line, the utility company should be notified
immediately.
