- If the chain gets stuck, or if cutting has to be
interrupted for any reason, release the switch
control and hold the saw in place, in the mate-
rial, unless the chain stops completely. Never
attempt to lift the saw from the cut or pull it
back if the chain is moving; otherwise kickback
may occur. Look for the reason the chain got
stuck and fi nd a way to remedy it.
- If you restart the saw with the chain in the work
piece, centre the chain in the cut groove and
make sure the teeth do not strike the material.
If the chain gets stuck, the saw may be pushed
upwards from the work piece after restart, or
kickback may occur.
- If you cut large boards, make sure you sup-
port them properly in order to avoid chain grip
and kickback. Large boards have a tendency to
bend under their own weight. The boards must
be padded on both sides, close to the cut and
near the margins.
- Do not use blunt or damaged chains. Chains
that are not sharpened or adjusted properly
cause excessive strain that may lead to de-
struction and possible injury.
- Before you start cutting, make sure the levers
that determine the cover and tilt of the guide
bar are tightened properly. If the guide bar po-
sition adjustment changes during cutting, it
may get stuck and kickback may occur.
- Do not cut by “dipping into the material”; this
is prevented by the guard plate assembly. The
guard plate must not be removed.
- Make sure your hands are at a safe distance
from the cut location and from the chain. Grip
the auxiliary handle with your other hand. If
you hold the saw with both hands, you cannot
cut yourself.
- Do not put your hands underneath the mate-
rial you are cutting. The guard plate cannot
protect you fully from the chain underneath
the piece you are cutting.
- Never hold the piece you are cutting in your
hand or over your knee. Fix the work piece on
a fi rm base. The piece that is being cut must
be properly supported to minimise the risk of
any part of your body coming into contact with
it, getting the chain stuck or losing the control
over the tool.
- When cutting lengthwise, use the guide bar,
guide ruler or parallel stop. This improves the
accuracy of the cut, and reduces the risk of
getting stuck in it.
- Always use the guide bar, the chain and the
chain sprocket recommended by the manu-
facturer. The bar must be properly secured.
- Check to make sure the original chain sprock-
et cover is intact. The original cover of the
chain sprocket must not be used if damaged
or incomplete, and must not be replaced with
any other component, e.g., a nut. The clamping
system must be designed with special consid-
eration of your saw, taking into account optimal
operation and work safety.
- Before placing the insulation saw on a work-
bench or on the fl oor, always make sure the
chain is not moving, and the saw is leaning on
the guard plate. When running down, an unpro-
tected chain causes reverse motion of the saw
and cuts everything in its path. Be aware of the
time the chain needs to stop after the switch
is released. The saw should be put away on a
level surface on the guide runner.
- The guard plate is an integral part of the ma-
chine; it must not be modifi ed, shortened or
dismantled. Make sure it is aligned with the
guide bar, and that the chain is tightened prop-
erly and does not touch the guard plate. The
minimum distance of the chain from the guard
plate is 5 mm, if the chain is already over-
stretched, it must be replaced with a new one.
- For the guard plate to work, it must be posi-
tioned in the cut groove. The guard plate is
prone to kickback on short cuts.
- Do not work with the saw if the guard plate is
bent.
- The guard plate must not be removed or modi-
fi ed.
- Proper chain tension is important. Check the
chain tension before you start working and then
continuously during the work. The cut move-
ment must be selected so as to avoid chain stop-
page.
- Never use chains whose cutting teeth angles
are designed solely for stationary machines.
- Do not forcibly change the selected cut direc-
tion while cutting.
- Safety covers and devices must not be removed,
and their proper operation must not be disa-
bled.
- Before you start working, check the lubrication
oil level and make sure the lubrication works.
- Do not cut pieces that are too big or too small
for the tool.
- Absolutely never plunge the operating machine
into fully enclosed surfaces. This poses a risk
of kickback injury!
