improve your cutting accuracy and reduce the
possibility of the saw blade jamming.
g) Always use saw blades of the correct size
and with a suitable mounting hole (e.g.
diamond-shaped or round). Saw blades
that do not match the mounting parts of the
saw will not rotate truly and will result in a loss
of control.
h) Never use damaged or incorrect saw
blade washers or screws. The saw blade
washers and screws have been specially
designed for your saw to ensure perfect per-
formance and operational safety.

Causes of recoil and related safety informa-
tion:
•
A recoil is the sudden reaction resulting from
a caught, jammed or incorrectly aligned saw
blade which may result in the saw leaping out
of the workpiece out of control and towards
the operator.
•
If the saw blade becomes caught or jammed
in a closing saw gap, it will block and the
power of the motor will cause the saw to leap
backwards towards the operator;
•
If the saw blade is twisted or incorrectly alig-
ned in the cut, the teeth in the rear saw blade
edge may become caught in the surface of
the wood, which results in the saw blade lea-
ping out of the saw gap and the saw leaping
towards the operator.
A recoil is the result of incorrect or wrong use of
the saw. It can be prevented by suitable precau-
tions, as described below.
a) Hold the saw firmly in both hands and
hold your arms in a position in which
you can absorb the forces created by
the recoil. Always hold the saw blade to
one side. Never hold the saw blade in a
straight line with your body. In the event of
a recoil the circular saw may leap backwards,
but the user can still handle the recoil forces if
he has taken suitable precautions.
b) If the saw blade jams or if you interrupt
your work, switch off the saw and hold
it steady in the workpiece until the saw
blade has reached a complete standstill.
Never attempt to take the saw out of the
workpiece or to pull it backwards whilst
the saw blade is moving, otherwise there
is a possibility of a recoil. Find and rectify
the cause of the jamming of the saw blade.

c) If you wish to restart a saw that is already
in the workpiece, center the saw blade
in the saw gap and check that the saw's
teeth are not caught in the workpiece. If
the saw blade is caught it may move out of
the workpiece or cause a recoil when the saw
is restarted.
d) Support large panels to reduce the risk
of a recoil by a jammed saw blade. Large
panels may sag under their own weight. The
panels must be supported on both sides, both
near the saw gap and also at the edge.
e) Do not use blunt or damaged saw blades.
Saw blades with blunt or incorrectly aligned
teeth will create increased friction due to the
saw gap being too small. In addition the saw
blade may also jam and cause recoil.
f)
Secure the cutting depth and cutting ang-
le settings before starting to saw. If the
settings change as you are sawing, the saw
blade may jam and cause recoil.
g) Be particularly careful with sawing in
existing walls or areas into which you
cannot see. The plunge-cutting saw blade
may block when sawing into concealed ob-
jects and thus cause recoil.
h) Do not use grinding wheels!
i)
The diameters of the saw blades used must
correspond to the diameters specified on the
hand-held circular saw blade!
j)
Use only recommended saw blades!
k) Use only blades with rotating speeds shown
on the blade which are equal to or higher than
the rotating speed shown on the power tool.
l)
Look for the right saw blade for the specific
material to be cut.
Safety instructions for saws with a swing
guard hood
Function of the bottom guard hood
a) Check that the bottom safety hood closes
perfectly before using the appliance. Do
not use the saw if the bottom safety hood
does not move freely and does not close
immediately. Never clamp or tie the bot-
tom guard hood in open position. If you
drop the saw by accident the bottom guard
hood may become bent. Open the safety
hood with the lever and ensure that it moves
freely and will not come into contact with the
saw blade or other parts regardless of the
cutting angle and depth.
b) Check the function of the spring on the
bottom safety hood. If the bottom guard
hood and springs are not in perfect wor-
