Instruction manual
∙ Use extreme caution when cutting brush and
saplings. The slender material may catch the saw chain
and be whipped toward you or pull you off of balance.
∙ Only use cutting equipment and accessories
recommended by the manufacturer.
∙ Keep the chain cutting teeth properly sharpened and
keep the saw chain properly tensioned! Keep all cutting
equipment well lubricated and properly maintained!
∙ Never use the chainsaw onehanded! Wrap
your fingers and thumb around the handles. Under
no circumstances should the machine be held by its
protective devices.
∙
The tool must never be operated with damaged or
dismantled safety guards. Do not operate the tool if it is
not properly assembled.
∙
Never use a chainsaw that has been modified in any
way from its original specification. Never use a chainsaw
that is faulty. Carry out the regular checks, maintenance
and service procedures. Some maintenance and service
measures must be carried out only by trained specialists.
∙ Never start a chainsaw unless all its components,
accessories and cutting tools are fitted correctly.
∙ Ensure that all spanners and other tools used to
adjust the machine have been removed and taken to a
safe distance before turning on the device.
∙ Never use the chainsaw above the height of your
shoulder and do not start to cut with the tip of the guide bar.
∙ Mobile trunks and branch timber should be fixed to
a trestle using clamps or other suitable tools.
∙ After turning off the machine, wait until the saw
chain comes to a complete stop: it will continue running
mechanically for a while. Do not make any attempt to
stop the saw chain on your own.
∙ Carry the chainsaw by the front handle with the
chainsaw switched off and away from your body.
ATTENTION! Under no circumstances
should you touch the cutting part of
the machine with your hands. Do not
touch the moving saw chain with your
hands.
CAUSES AND OPERATOR PREVENTION
OF THE KICKBACK
The word kickback is used to describe the sudden
reaction that happens when the upper quadrant of the
tip of the guide bar (7) (known as the “kickback zone”
[F1] ) touches an object and the chainsaw is kicked
backwards.
This dangerous reaction can happen when the guide bar
(7) touches sawn material, but also when the saw chain (6)
is blocked, causing the uplift of the chainsaw which rises
suddenly in the opposite direction, towards the operator.
When the kickback occurs, the machine reacts in this
unexpected manner, suddenly and violently, and can
cause serious, even fatal injury to the operator or to
other people nearby.
The risk of kickback is increased if you use the wrong cutting
equipment or an unsharpened or loose saw chain (6).
When conducting side, oblique and lateral cuts, special
care should be taken, because the notched rest (8)
cannot be used in these situations.
It is necessary that you understand what the causes of
kickback are and how to avoid them, by taking care and
using the right working technique.
To avoid chainsaw kickback:
∙
Apply the machine as evenly as possible to the
surface to be cut.
∙
Work in stable and balanced position.
∙ Never work with a loose or worn saw chain (6);
sharpen the saw chain (6) properly.
∙ Never saw above shoulder height.
∙ Never saw with the upper edge or the end of guide
bar (7). [F2] ; [F3]
∙ Always firmly hold the machine with two hands.
∙ Use the notched rest (8) as a lever. [F4]
∙ Pay attention to the correct tension of the saw chain (6).
∙ Pay attention not to hit the running saw chain (6)
on hard material (e.g. metal, mortar, stones etc) which
can be also hidden in the wood or near the area you
are working on.
∙ Do not attempt to get into an existing cut with the
running saw chain (6).
UNPACKING
