OPERATING
TIPS
• Check chain t ension before first u se
and after 1 minute ofoperation.
See
CHAIN TENSION
inthe MAINTENANCE
section.
• Cut wood o nly. Donot c utmetal,
plastics, masonry,
non-wood
building
materials,
etc.
• Stop the saw ifthe chain s trikes
a
foreign object.
Inspect the saw and
repair parts as necessary.
• Keep the chain out of dirt and sand.
Even a small amount of dirt will
quickly
dull a chain and increase
the
possibility
of kickback.
• Practice cutting a few small logs us-
ing the following
steps. This will help
you get the "feel" of using your saw
before you begin a major sawing op-
eration.
• Squeeze
the throttle trigger and a!-
low 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.
• Release the throttle trigger as soon
as the cut is completed,
allowing
the engine to idle. If you run the
saw at full throttle without a cutting
load, unnecessary
wear can occur
to the chain, bar and engine.
It is
recommended
that the engine
not be operated
for longer
than
30 seconds
at full throttle.
• To avoid losing control when cut is
complete,
do not put pressure
on
saw at end of cut.
• Stop engine before setting saw down.
TREE FELLING TECHNIQUES
X1=
_
_!_WARNING:
Check for broken or
dead 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 able to see well, nor during bad
weather such as rain, snow, or strong
winds, etc.
• Carefully
plan your sawing operation
in advance.
• Clear the work area. You need a
clear area all around the tree so you
can have secure footing.
• 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.
• Study the natural conditions
that can
cause the tree to fall in a particular
direction.
These conditions
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 determine
the di-
rection 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.
• 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.
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.

FELLING
LARGE TREES
(6 inches in diameter or larger)
The notch method is used to fell large
trees. A notch is cut on the side of the
tree in the desired direction
of fall. After
a felling cut is made on the opposite
side of tree, the tree will tend to fall in
the direction
of the notch.
