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
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
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.11A.
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.

AUTOMATIC OILER
Your chain saw is equipped with an
automatic clutch driven 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.

The pressure may cause the bar and chain
to rotate. If the rotating chain strikes some
other object, a reactive force may cause
moving chain to strike the operator.
GENERAL GUIDELINES FOR FELLING
TREES:
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:
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.11B)
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
