DCS-5000
Before cutting, clear the area around
the tree. You will need good footing
while working and you should be able
to work the saw without hitting any
obstacles. Next, select a path of retreat.
When the tree begins to fall you should
retreat away from the direction of fall
at a 45-degree angle and at least 3 m
(10 ft.) from the trunk to avoid the trunk
kicking back over the stump.
Begin the cut on the side to which
the tree is to fall. Cut a notch about
1/3 of the way into the tree. The
position of this notch is important
since the tree will try to fall "into"
the notch. The felling cut is made
on the side opposite the notch and
at a level about 5 cm (2 in.) above
the bottom of the notch. Do not try
to cut through to the notch with the
felling cut.
The remaining wood between the
notch cut and felling cut about 5 cm
(2 in.) will act as a hinge when the
tree falls, guiding it in the desired
direction. When the tree starts to
fall, kill the motor, place the saw on the ground and make your retreat quickly.
To fell big trees with a diameter
exceeding twice the bar length, start the
notching cuts from one side and draw
the saw through to the other side of the
notch. Start the back cut on one side
of the tree, pivoting the saw through
to form the desired hinge on that side.
Then remove the saw for the second
cut. Insert the saw in the first cut, very
carefully so as not to cause kickback.
The final cut is made by drawing the
saw forward in the cut to reach the
hinge.
