• SAW CHAIN / BAR LUBRICATION
Adequate lubrication of the saw chain is essential at all
times to minimize friction with the guide bar.
Never starve the bar and chain of oil. Running the saw
with too little oil will decrease cutting efficiency, shorten
saw chain life, cause rapid dulling of chain, and cause
excessive wear of bar from overheating. Too little oil is
evidenced by smoke, bar discoloration or pitch build-up.
NOTE: Saw chain stretches during use, particularly
when it is new, and it will occasionally be necessary to
adjust and tighten it. New chain will require adjustment
after about 5 minutes of operation.
• AUTOMATIC OILER
Your chain saw is equipped with an automatic gear dri-
ven oiler system. The oiler automatically delivers the
proper amount of oil to the bar and chain. As the engine
speed increases, so does the oil flow to the bar pad.
There is no flow adjustment. The oil reservoir will run out
at approximately the same time as the fuel supply runs
out.
GENERAL CUTTING INSTRUCTIONS
• 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.
FELLING A TREE:
WARNING: 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. 12.
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.
IMPORTANT: Felling trees is prohibited without the nec-
essary training!
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 proper-
ty. 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 (Fig.
12):
Normally felling consists of 2 main cutting operations,
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.
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.
WARNING: 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) (Fig. 13)

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 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.
WARNING: Before making the final cut,
always recheck the area for bystanders,
animals or obstacles.
FELLING CUT:
1. Use wooden or plastic wedges (A) to prevent binding
the bar or chain (B) in the cut. Wedges also control
felling (Fig. 14A).
2. When diameter of wood being cut is greater than the
bar length, make 2 cuts as shown (Fig. 14B).

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 (Fig. 12).
