out of the saw gap and the circular saw to
jump backwards in the direction of the operator.
Kickback results from the incorrect and / or unsuita­
ble use of the saw. It can be prevented by taking
the appropriate precautions as described below.
a) Hold the saw with both hands and
bring your arms into a position in which
you will be able to control any kick-
back forces. Always stand to the side
of the saw blade and never bring your
body in line with the saw blade. The
circular saw can jump backwards when a kick-
back happens, but the operator can control the
kickback forces by taking certain precautions.
b) If the saw blade jams or you stop
work for a while, switch the saw off
and hold the saw blade in the materi-
al without moving it until the blade
comes to a complete stop. Never try to
remove the saw from the workpiece
or move it backwards until the saw
blade has stopped moving, otherwise
a kickback may occur. Determine and
rectify the reason for the saw blade jamming.
c) If you wish to restart a saw that has
been inserted into the workpiece, cen-
tre the saw blade in the saw gap and
check that the saw teeth do not catch
on the workpiece. If the saw blade jams, it
may move itself out of the workpiece or cause
a kickback when the saw is restarted.
d) Supporting large boards while cutting
will reduce the risk of kickback caused
by a jammed saw blade. Large boards
may bend under their own weight. Boards
must be supported on both sides as well as
near the saw gap and at the edges.
e) Do not use blunt or damaged saw
blades. Saw blades with blunt or misaligned
teeth are in effect too wide for the designed
saw gap and this gives rise to increased fric-
tion, jamming and kickback.
f) Tighten the cutting depth and angle
setting screws before starting the saw.
If these settings move during sawing, this can
lead to the saw blade jamming and kickback.
g) Be particularly careful when pocket
cutting in existing walls or other are-
as where you cannot see what you
are cutting into. The plunging blade could
jam in a hidden object and cause kickback.
Safety advice
for plunge saws
a) Before you use the saw, always check
that the blade guard closes properly.
Do not use the saw if the blade guard
does not move freely or close immedi-
ately. Never jam or tie the blade guard
in the open position. The blade guard can
be damaged if the saw falls on to the floor.
Ensure that the blade guard moves freely and
touches neither the saw blade nor any other
components irrespective of cutting angle and
depth.
b) Check that the spring on the blade
guard functions properly and that it is
in good condition. If the blade guard
or spring does not function properly,
have the saw serviced before you use
it. Damaged parts, sticky deposits or accumu-
lations of splinters can delay the operation of
the blade guard.
c) Ensure that the guide plate prevents
the saw from being displaced side-
ways when performing a plunge cut
not at right angles to the workpiece
surface. Sideways movement can cause the
saw blade to jam and the saw to kickback.
d) Do not put the saw down on a work
bench or the floor without the blade
guard covering the saw blade. If unpro-
tected, a rotating saw blade moves the saw
against the cutting direction and saws whatever
is in its way. Always be aware that the saw blade
takes some time to stop.
J Ensure that the device is always used in accord­
ance with the advice in these operating instruc­
tions and only by persons over 16 years of age.
