possible internal electrical insulation failure.
WARNING
Your double insulated appliance has no serviceable parts
inside. Do not attempt to repair it yourself. For service infor-
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.
FELLING A TREE:
WARNING
A retreat path (A) should be planned and cleared as nec-
essary before cuts are started. The retreat path should
extend back and diagonally to the rear of the expected line
of fall, as illustrated in Figure 5-1A.
CAUTION
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.
NOTE: Direction of fall (B) is controlled by the notching cut.
Before any cuts are made, consider the location of larger
branches and natural lean of the tree to determine the way
the tree will fall.
WARNING
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 striking utility
wires; notify the utility company before making any cuts.
GENERAL GUIDELINES FOR FELLING
TREES:
Normally felling consists of two (2) main cutting oper-
ations, notching (C) and making the felling cut (D).
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.
1. Use wooden or plastic wedges (G) to prevent binding
the bar or chain (H) in the cut. Wedges also control
felling (Figure 5-1C).
2. When diameter of wood being cut is greater than the
bar length, make 2 cuts as shown (Figure 5-1D).
WARNING
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 engine, put chain saw down, and leave area along
retreat path (Figure 5-1A).
Before cutting with your saw, the CHAIN BRAKE should
®
be tested as follows:
A.
Make sure the CHAIN BRAKE is disengaged (Figure
®
4-4A).
B.
Place the saw on a firm, flat, dry surface that is clear
of any debris. Do not let the saw come in contact with
any objects.

should encircle the handle.

While the motor is running, activate the CHAIN

BRAKE by rolling your left hand forward against the
lever.
A
Chain and motor should stop abruptly.
WARNING
If the chain and motor fail to stop when the CHAIN BRAKE

5-1A
is engaged, take the saw to the nearest Authorized Service
®
Center. Do not use the saw if the CHAIN BRAKE is not in
proper working order.

EXTENSION CORDS
When using an electric chain saw, plug it into the extension
cord only when you are ready to cut wood. Connect the
extension cord to a 110/120 voltage outlet. see chart 3-6.
CAUTION
A cord that is hot to the touch is overloaded.
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.
5-1B
WARNING
WARNING
G
H
Do not operate your chain saw in a wet or damp environ-
ment. Do not expose the saw to rain, snow or sleet.
Moisture will cause short circuits. Replace or repair any
damaged or frayed extension cords before using your saw.
Keep the cord away from the cutting area and position the
cord so that it will not be caught on branches or other
objects during cutting.
Never walk in front of a tree that has been notched.
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)
(Figure 5-1B).
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 prevent the
guide bar from binding in the felling cut if you have mis-
judged the falling direction. Make sure no bystanders have
entered the range of the falling tree before you push it over.
WARNING
Before making the final cut, always recheck the area for
bystanders, animals or obstacles.
5-1C
DOUBLE INSULATION
WHEN SERVICING USE
ONLY IDENTICAL REPLACEMENT PARTS
Do not use if the cord or plug is damaged. Your appliance
is double insulated to help protect against electric shock.
Double insulation construction consists of two(2) separate
“layers”of electrical insulation.
Appliances built with this insulation system are not intend-
ed to be grounded. As a result, the extension cord used
with your appliance can be plugged into any conventional
120
volt electrical outlet.
