General using method
1.Use the chain saw only with secure footing.
2.Always hold the chain saw firmly with both
hands. Front grip with the left hand and
rear grip with the right hand. Fully grip both
handles at all times during operation. Never
operate chain saw using only one hand. Hold
the chain saw at the right-hand side of your
body.
3. Switch on the saw and always allow the chain
blade to reach full speed before it makes
contact with the wood.
The proper techniques for basic felling,
limbing, and cross-cutting
Felling a tree
When bucking and felling operations are being
performed by two or more persons at the same
time, the felling operations should be separated
from the bucking operation by a distance of at
least twice the height of the tree being felled.
Trees should not be felled in a manner that
would endanger any person, strike any utility line
or cause any property damage. If the tree does
make contact with any utility line, the company
should be notified immediately.
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.
An escape path should be planned and cleared
as necessary before cuts are started.
The escape path should extend back and
diagonally to the rear of the expected line of fall .
Before felling is started, consider the natural lean
of the tree, the location of larger branches and
the wind direction to judge which way the tree
will fall. Remove dirt, stones, loose bark, nails,
staples and wire from the tree.
Notching undercut
Make the notch 1/3 the diameter of the tree,
perpendicular to the direction of falls.
Make the lower horizontal notching cut first. This
will help to avoid pinching either the saw chain
or the guide bar when the second notch is being
made.
Felling back cut
Make the felling back cut at least 1.97 in. higher
than the horizontal notching cut.
Keep the felling back cut parallel to the horizontal
notching cut. Make the felling back cut so enough
wood is left to act as a hinge. The hinge wood
keeps the tree from twisting and falling in the
wrong direction. Do not cut through the hinge. As
the felling gets close to the hinge, the tree should
begin to fall. If there is any chance that the tree
may not fall in desired direction or it may rock
back and bind the saw chain, stop cutting before
the felling back cut is complete and use wedges
of wood, plastic or aluminum to open the cut and
drop the tree along the desired line of fall. When
the tree begins to fall remove the chain saw from
the cut, stop the motor, put the chain saw down,
then use the retreat path planned. Be alert for
overhead limbs falling and watch your footing.
Limbing a tree
Limbing is removing the branches from a fallen
tree. When limbing leave larger lower limbs to
support the log off the ground. Remove the small
limbs in one cut.
Branches under tension should be cut from the
bottom up to avoid binding the chain saw.
