WARNING: Activate the chain brake
slowly and deliberately. Keep the chain from
touching anything; do not let the saw tip
forward.
6. Chain should stop abruptly. When it does, im-
mediately release the throttle trigger.
WARNING: If chain does not stop, turn
engine off and take your unit to the nearest
SPARKY authorised service centre for repair.
7. If chain brake functions properly, turn the en-
gine off and return the chain brake to the dis-
engaged position.

SAW cHAIN / bAR LUbRIcAtIoN

Adequate lubrication of the saw chain is essen-
tial 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 effi-
ciency, 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, particu-
larly 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 opera-
tion.

AUtomAtIc oILER

Your chain saw is equipped with an automatic gear
driven oiler system. The oiler automatically deliv-
ers 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.

fELLING
Felling is the term for cutting down a tree. Small
trees up to 15–18 cm in diameter are usually cut in
a single cut. Larger trees require notch cuts. Notch
cuts determine the direction the tree will fall.
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.
NotE. Direction of fall (B) is controlled by the notch-
ing 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.

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 2 main cutting opera-
tions, 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
