Maintenance - SPARKY TV 3540 Notice Originale

completely cut through, control over the felling di-
rection 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 misjudged the falling direc-
tion. 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 (G) to prevent
binding the bar or chain (H) in the cut. Wedg-
es also control felling (Fig.11C).
2. When the diameter of wood being cut is great-
er than the bar length, make 2 cuts as shown
(Fig. 11D).
WARNING: As the felling cut gets close
to the hinge, the tree should begin to fall. When
the tree begins to fall, remove the saw from the
cut, stop the engine, put the chain saw down,
and leave area along the retreat path (Fig. 1A).
LIMBING
Limbing a tree is the process of removing the
branches from a fallen tree. Do not remove sup-
porting limbs (A) until after the log is bucked (cut)
into lengths (Fig. 12).
Branches under tension should be cut from the
bottom up to avoid binding the chain saw.
WARNING: Never cut tree limbs while
standing on tree trunk.
BUCKING
Bucking is cutting a fallen log into lengths. Make
sure you have a good footing and stand uphill of
the log when cutting on sloping ground. If possi-
ble, the log should be supported so that the end
to be cut off is not resting on the ground. If the log
is supported at both ends and you must cut in the
middle, make a downward cut halfway through the
log and then make the undercut. This will prevent
the log from pinching the bar and chain. Be careful
that the chain does not cut into the ground when
bucking as this causes rapid dulling of the chain.
When bucking on a slope, always stand on the
Original instructions
uphill side.
1. Log supported along entire length: Cut from
top (over buck), being careful to avoid cutting
into the ground (Fig. 13A).
2. Log supported on one end: First, cut from bot-
tom (under buck) 1/3 diameter of log to avoid
splintering. Second, cut from above (over
buck) to meet first cut and avoid pinching
(Fig. 13B).
3. Log supported on both ends: First, over buck
1/3 diameter of log to avoid splintering. Sec-
ond; under buck to meet first cut and avoid
pinching (Fig. 13C).
NOTE: The best way to hold a log while bucking is
to use a sawhorse. When this is not possible, the
log should be raised and supported by the limb
stumps or by using supporting logs. Be sure the
log being cut is securely supported.
BUCKING USING A SAW HORSE
For personal safety and ease of cutting, the cor-
rect position for vertical bucking is essential
(Fig. 14).
A. Hold the saw firmly with both hands and keep
the saw to the right of your body while cut-
ting.
B. Keep the left arm as straight as possible.
C. Keep balance on both feet.
CAUTION: While the saw is cutting, be sure the
chain and bar are being properly lubricated.
IX - Maintenance
All chain saw service, other than items listed here
in your user manual maintenance instructions,
must be accomplished by authorised persons in
authorised service centres for warranty and post-
warranty servicing of SPARKY tools.
PREVENTIVE MAINTENANCE
A good preventive maintenance program of regu-
lar inspection and care will increase life and im-
prove performance of your SPARKY chain saw.
This maintenance checklist is a guide for such a
program.
Cleaning, adjustment, and parts replacement may
be required, under certain conditions, at more fre-
quent intervals than those indicated.
