General Cutting Instructions; Automatic Oiler - Sparky TV 3540 Originalbetriebsanleitung

5. Squeeze the throttle trigger to 1/3 throttle,
then immediately activate the chain brake le-
ver (C) (Fig. 10).
WARNING: Activate the chain brake
slowly and deliberately. Keep the chain from
touching anything; do not let the saw tip for-
ward.
6. The chain should stop abruptly. When it does,
immediately release the throttle trigger.
WARNING: If the chain does not stop,
turn the engine off and take your unit to the
nearest SPARKY authorised service centre for
repair.
7. If the chain brake functions properly, turn the
engine off and return the chain brake to the
disengaged position.
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 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.
WARNING: Do not put pressure on
the saw when reaching the end of the cut. The
pressure may cause the bar and chain to rotate.
If the rotating chain strikes some other object, a
reactive force may cause the moving chain to
strike the operator.

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.
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.
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 (F) of sufficient width and strength. The
notch should be wide enough to direct the fall of
the tree for as long as possible.
Make the felling cut (D) from the other side of the
tree and 3–5 cm above the edge of the notch (C)
(Fig. 11B).
Never saw completely through the trunk. Always
leave a hinge (F). The hinge prevents untimely
fall of the tree and guides the tree. If the trunk is
instructions
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 on Fig. 11A.
WARNING: Do not cut down a tree dur-
ing high or changing winds or if there is a dan-
ger 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: Never walk in front of a tree
that has been notched.
