2.2 SAFETy InSTruCTIonS For All SAwS
a) dAngEr: do not put your hands in the
sawing area or on the saw blade. use your
second hand to hold onto the auxiliary
handle or the motor housing. If both hands
are being used to hold the circular saw, then
they cannot be injured by the saw blade.
b) do not grip underneath the workpiece. The
safety guard cannot protect you against the
saw blade under the workpiece.
c) Adjust the cutting depth to the thickness of
the workpieces. The saw should protrude by
no more than the height of one tooth under the
workpiece.
d) never hold the workpiece to be sawn in
your hand or over your leg. Secure the
workpiece in a stable holder. It is important
to fasten the workpiece firmly in order to
minimise the danger of contact with the body,
jamming of the saw blade or loss of control.
e) grip the electric power tool by the
insulated handling surfaces only when you
are carrying out work in situations where
the tool insert may make contact with
hidden power lines or its own power cable.
Contact with a live wire places a voltage on
the metal parts of the electric power tool and
will lead to an electric shock.
f) Always use a stop or a straight edge guide
when making longitudinal cuts. These
improve the accuracy of the cut and reduce
the possibility of the saw blade jamming.
g) Always use saw blades of the right size
and with matching locating holes (e.g.
star-shaped or round). Saw blades which are
not matched to the mounting pieces of the saw
will run eccentrically and lead to loss of control.
h) never attach the saw blade using damaged
or incorrect washers or screws. The saw
blade washers and screws are specially
constructed for your saw, to give optimal
performance and operating safety.
2.3 AddITIonAl SAFETy InSTruCTIonS
For All SAwS
The causes of kickback and how to avoid them:
• A kickback is a sudden reaction due to
snagging, jamming or misalignment of the saw
blade, which results in the uncontrolled saw
jumping out of the workpiece and moving
towards the operator.
• If the saw blade having snagged or jammed in
a self-closing saw cut, is locked and the
motors power jolts the device back towards
the operator.
• If the saw blade is rotated or misaligned in the
saw cut, the teeth on the rear edge of the
blade can become hooked in the surface of
the workpiece, whereby the saw blade jumps
out of the cut and the saw springs back in the
direction of the operator.
A kickback is the result of improper or incorrect
use of the saw. It can be avoided by taking
suitable precautions, as described below.
a) Hold the saw firmly with both hands and
place your arms in such a position that you
can absorb the force of a kickback. Always
keep yourself to one side of the saw blade
and never bring the blade in line with your
body. In the event of a kickback, the circular
saw may spring backwards; however, the
operator can control the kickback force if
suitable measures have been taken.
b) If the saw blade becomes jammed or if you
interrupt the work, switch the saw off and
keep it held gently in the material until the
saw blade has come to rest. never attempt
to extract the saw from the workpiece or to
pull it backwards while the saw blade is
moving; otherwise a kickback may occur.
Find and remove the cause for the saw-blade's
jamming.
c) If you wish to restart a saw that is already
in the workpiece, centre the saw blade in
the cut and check that the teeth are not
snagged in the workpiece. If the saw blade
jams, it may run out of the workpiece or cause
a kickback when the saw is restarted.
d) Provide support for large sheets to reduce
the risk of a kickback through jamming of
the saw blade. Large sheets can bend under
their own weight. The sheets must be
supported on both sides, at the edges and
close to the saw cut.
e) do not use blunt or damaged saw blades. If
saw blades with blunt or misaligned teeth are
used, the saw cut is too narrow resulting in
increased friction, jamming of the blade and
kickback.
