OPERATING INSTRUCTIONS

A

B

Do not cut down a
tree during high or

changing winds or if there is a danger to
property. Consult a tree professional.Do not
cut down a tree if there is a danger of strik-
ing utility wires; notify the utility company
before making any cuts.

WARNING:

FELLING

Felling is the term for cutting down a tree. Small trees up
to 6-7 inches (15-18cm) in diameter are usually cut in a
single cut. Larger trees require notch cuts. Notch cuts
determine the direction the tree will fall.

NOTE: Direction of fall (B) is controlled by the notching

cut. Before any cuts are made, consider the loca-
tion of larger branches and natural lean of the tree
to determine the way the tree will fall.

A retreat path (A)
should be planned

and cleared as necessary before cuts are
started. The retreat path should extend back
and diagonally to the rear of the expected
line of fall, as illustrated in Fig. 8.

WARNING:

If felling a tree on
sloping ground, 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.

CAUTION:

Normally felling consists of 2 main cutting operations,
notching (C) and making the felling cut (D) (Fig. 9).

Start making the upper notch cut (C) on the side of the
tree facing the felling direction (E). Be sure you don t make
the lower cut too deep into the trunk(Fig. 9).

The notch (C) should be deep enough to create a hinge (F)
of sufficient width and strength. The notch should be wide
enough to direct the fall of the tree for as long as possible
(Fig. 9).

Never walk in front of
a tree that has been

notched.

WARNING:

Never saw completely through the trunk. Always leave a
hinge. The hinge guides the tree. If the trunk is completely
cut through, control over the felling direction is lost.

Insert a wedge or felling lever in the cut well before the
tree becomes unstable and starts to move. This will pre-
vent the guidebar from binding in the felling cut if you
have misjudged the falling direction. Make sure no
bystanders have entered the range of the falling tree
before you push it over.

Before making the
final cut, always recheck

the area for bystanders, animals or obstacles.

WARNING:

Make the felling cut (D) from the other side of the tree and
1.5 - 2.0 inches (3-5 cm) above the edge of the notch (C)
(Fig. 9).

Felling Cut:
1. Use wooden or plastic wedges (G) to prevent binding

the bar or chain (H) in the cut. Wedges also control
felling (Fig. 10).

2. When diameter of wood being cut is greater than the

bar length, make 2 cuts as shown (Fig. 11).

As the felling cut
gets close to the

hinge, the tree should begin to fall. When
tree begins to fall, remove saw from cut,
stop motor, put chain saw down, and leave
area along retreat path (Fig. 8).

WARNING:
