the workpiece. The automatic blade guard
must be allowed to operate automatically for
all saw cuts.
d) Do not put the saw down on a
work bench or the floor without the
automatic blade guard covering
the saw blade. If unprotected, 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.
Special safety advice for circular saws
and riving knives
a) Use the riving knife matched to the
installed saw blade. The riving knife
must be thicker than the body of the blade but
thinner than the width of the teeth.
b) Adjust the riving knife as described
in the operating instructions. If its
thickness, position or alignment is incorrect,
this can lead to the riving knife not effectively
preventing kickback.
c) Always use the riving knife, except
for plunge cuts. After completing plunge
cutting, put the riving knife back in place. The
riving knife interferes with plunge cuts and can
result in kickback.
d) For the riving knife to work properly,
it must be within the saw gap. The
riving knife is ineffective in preventing kickback
for short cuts.
e) Do not operate the saw if the riving
knife is bent out-of-true. Even a slight defect
can cause the blade guard to close too slowly.
To avoid the device kicking back:
Kickback occurs as a result of incorrect use or
misuse 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 withstand
any kickback forces. Always stand
to the side of the saw blade and
never bring your body in line with
the saw blade. When kickback occurs,
the circular saw may jump backwards but the
operator can control the kickback forces by
adopting suitable precautions.
b) If the saw blade jams or sawing
stops for another reason, release
the ON/OFF switch and hold the saw
in the workpiece without moving
it until the saw blade comes to a
complete standstill. Never try to
remove the saw from the workpiece
or move it backwards until the saw
blade has stopped moving or cannot
cause a kickback. Find the reason for the
saw blade jamming and take the appropriate
action to rectify it.
c) If you wish to restart a saw that has
been inserted into the workpiece,
centre 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) Support boards whilst cutting to
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
friction, jamming and kickback.
f) Make sure that the cutting depth
and angle setting fastenings are
tightened before sawing starts. If
these settings move during sawing, this can
lead to the saw blade jamming and kickback.
g) Be particularly careful when
carrying out a plunge cut in an
obscured area, e.g. in an existing
wall. The plunging blade could jam in a
hidden object and cause kickback.
