- If the chain is skewed or not aligned with the
cut, the teeth on the rear chain margin may
strike the wood surface from the top, the chain
may jump out of the cut and the saw may eject
back toward the user.
- 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 support
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 destruction
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 position
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 ma-
terial 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 im-
proves 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
sprocket 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 dis-
mantled. Make sure it is aligned with the guide
bar, and that the chain is tightened properly 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 overstretched, 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
modifi ed.
- Proper chain tension is important. Check the chain
tension before you start working and then contin-
uously during the work. The cut movement must
be selected so as to avoid chain stoppage.
- Never use chains whose cutting teeth angles are
designed solely for stationary machines.
- Do not forcibly change the selected cut direction
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!
- When operating the tool in enclosed areas, it is
necessary to provide suffi cient ventilation or ex-
haust. Avoid cutting hazardous materials, such
as asbestos.
- Remove all foreign particles from the material
to be cut, especially metal, which will damage
the tool and may lead to injury.
- Use caution when discarding sawdust! If the
sawdust removal port is plugged, you must turn
off the machine and unplug it. Only when the
