kickback, the circular saw can jump backwards, but with
adequate caution the operator can deal with the energy
of the kickback.
b) If the saw blade jams or you want to interrupt your
work, then turn the saw off and keep the work piece still
until the saw blade comes to a full stop. Never try to re-
move the saw from the work piece or pull it out when the
saw blade is moving since then a kickback can occur.
Find out the cause of the jam and remove it.
c) If you want to start up a saw that is in the work piece,
centre the saw blade in the sawed groove and check that
the saw blade teeth are not caught in the work piece. If
the saw blade is jammed, it can jump out of the work
piece or cause a kick back when it is started up.
d) Support larger work pieces in order to reduce the risk
of a kick back due to a saw blade jam. The weight of
larger work pieces can cause them to bend. Large pieces
must be supported on both sides, both near the sawing
slot as well as on the edges.
e) Do not use dull or damaged saw blades. Saw blades
with dull or misaligned teeth increase the friction, in the
sawing slot, cause saw blade jams and kickbacks.
f ) Before you start sawing, tighten the adjustments for
the cut depth and angles. If you change settings while
sawing, the saw blade can jam and a kickback is the
result.
g) Be particularly careful when making “inserted cuts” in
walls that already exist or other areas where you cannot
see what is behind the surface. When the saw blade is
inserted into the wall it can be blocked by hidden objects
and cause a kick back.
mSafety instructions for inserted circular saw use
a) Each time before you use the saw, make sure that the
protective covering closes. Do not use the saw if the pro-
tective covering cannot move freely and does not close
immediately. Never clip or tie the protective covering
in an opened position. If the saw should accidentally
fall to the ground, the protective covering can get bent.
Make sure that the protective covering can move freely
and does not touch the saw blade or other parts in all
cutting positions.
b) Check the condition and function of the spring for the
protective covering. Have the saw repaired before use if
the protective covering and spring do not work perfectly.
Damaged parts, sticky residuals or piles of saw dust can
interfere with the working of the lower protective cover.
c) When making an “inserted cut” that does not describe
a right angle, make sure that the saw is guarded against
slipping to the side. Slippage can lead to a saw blade
jam and a kickback.
d) Do not put the saw on the workbench or the fl oor wi-
thout making sure that the protective cover is over the
saw blade. An unprotected, running saw blade can move
the saw against the cutting direction and saw what is in
the way. Check the delay time of the saw.

Safety instructions for all saws
a) DANGER: Do not put your hands in the sawing area or
on the saw blade. Keep your second hand on the extra
handle of the motor housing. If both hands are holding
the saw, neither can be injured by the saw blade.
b) Do not put your hands under the work piece. The pro-
tective cap cannot protect your hands from the blade
when they are under the work piece.
c) Adjust the cutting depth to the thickness of the work
piece. Less than one complete sawing tooth should be
visible under the work piece.
d) Never hold the work piece that is to be sawn in your
hand or over your leg. Make sure that the work piece has
a stable balance. It is important that the work piece is
held securely, in order to minimize the danger of contact
of a body part with the saw, loss of control over the saw,
or jamming of the blade.
e) Hold the equipment on the insulated handles, when
you undertake work in which the tool being used could
come into contact with hidden electrical wires, or its own
cable. Contact with a live power source can electrify the
metal parts of the tool and lead to an electrical shock.
f ) When making a long cut, always use a stop chock or a
straightedge. This improves the accuracy of the cut and
reduces the chance that the saw blade jams.
g) Always use the correct size of saw blades and make
sure they have the right locating bore (e.g. Star shaped
or round). Saw blades that do not fi t the assembly of the
saw do not run correctly and cause loss of control.
h) Never use damaged or incorrect saw blade shims or
screws.
The saw blade shims and screws are designed especially
for your saw, for optimal performance and operating sa-
fety.

Additional safety instructions for all saws
Causes and prevention of kickbacks:
• A kickback is a sudden reaction due to a caught, jam-
med or incorrectly adjusted saw blade, which leads to
the saw rearing up in an uncontrolled manner and moving
out of the work piece towards the operator.
• If a saw blade catches or jams in the sawing edge that
closes behind it, it is blocked and motor’s drive pushes
the saw back in the direction of the operator.
• If the saw blade twists in the saw groove or is incor-
rectly positioned, the teeth at the rear side of the saw
blade edge catch in the surface of the work piece. The
saw then moves out of the saw groove and springs back
in the direction of the operator.
• A kickback results from an incorrect or faulty use of
the saw. It can be prevented, as will be described in the
following, by appropriate cautionary measures.
a) Hold onto the saw with both hands and position your
arms so that they can absorb any energy from a kick-
back. Always keep to the side of the saw blade, and
never bring it into line with your body. In the case of a
