• Always wait until the machine has come to
a complete stop before placing it down. The
tool insert can jam and lead to loss of control
over the power tool.
• Do not use a machine with a damaged mains
cable. Do not touch the damaged cable
and pull the mains plug when the cable is
damaged while working. Damaged cables
increase the risk of an electric shock.
• If the cable is damaged or cut though
while working, do not touch the cable
but immediately pull the mains plug.
Never use the machine with a
damaged cable.
• Wear safety glasses, hearing
protectors and protective gloves. Wear
a face mask.
• For long hair, wear hair protection.
Work only with close-fitting clothes.
• For the mounting and replacing
of the circular saw blade 17, wear
protective gloves.
• When working, never place a hand or
fingers in front of the circular saw blade.
The improper use of accessories which
are not intended for this machine type
increases the danger of an accident and
can lead to damage to the machine.
• Connect machines that are used in the open
via a residual current device (RCD).
• DANGER: Keep hands away from the cutting
area and the blade. Keep your second
hand on the auxiliary handle or the motor
housing. If both hands are holding the saw,
they cannot be cut by the saw blade.
• Do not reach underneath the workpiece.
The blade guard cannot protect you from the
blade below the workpiece.
• Adjust the cutting depth to the thickness
of the workpiece. Less than a full tooth of
the blade teeth should be visible below the
workpiece.
• Never hold the piece being cut in your hands
or across your leg. Secure the workpiece on
a stable support. It is important to support
the work properly to minimize body exposure,
blade binding, or loss of control.
• Hold the power tool only by the insulated
gripping surfaces when performing an
operation where the cutting tool may
contact hidden wiring or its own power
cord. Contact with a “live” wire will also make
exposed metal parts of the power tool “live”
and shock the operator.
• When ripping always use a rip fence or
straight edge guide. This improves the
accuracy of cut and reduces the chance of
blade binding.
• Always use saw blades with correct size
and shape (diamond versus round) of
arbour holes. Blades that do not match
the mounting hardware of the saw will run
eccentrically,causing loss of control.
• Never use damaged or incorrect blade
washers or bolts. The blade washers and
bolts were specially designed for your saw,
for optimum performance and safety of
operation.
• Causes and operator prevention of kickback:
– Kickback is a sudden reaction to a pinched,
bound or misaligned saw blade, causing an
uncontrolled saw to lift up and out of the
workpiece toward the operator.
– When the blade is pinched or bound tightly by
the kerf closing down, the blade stalls and the
motor reaction drives the unit rapidly back
toward the operator.
– If the blade becomes twisted or misaligned
in the cut, the teeth at the back edge of the
blade can dig into the top surface of the wood
causing the blade to climb out of the kerf
and jump back toward the operator. Kickback is
the result of saw misuse and/or incorrect
operating procedures or conditions
and can be avoided by taking proper precautions
as given below.
The figure D shows the correct and incorrect
form of if leading the tool.
• Maintain a firm grip with both hands on
the saw and position your arms to resist
kickback forces. Always position yourself to
the side of the saw blade, so that your body
is never in line with the saw blade. Kickback
can cause the saw to jump backwards, but
kickback forces can be controlled by the
operator if proper precautions are taken.
• In case the saw blade jams or if the sawing
is discontinued, switch the saw off and hold
it motionless in the material until the blade
comes to a complete stop. Never attempt to
remove the saw from the work or pull the saw
backward while the blade is in motion
or kickback may occur. Investigate and take
corrective action to eliminate the cause of the
blade binding.
• When restarting a saw in the workpiece,
centre the saw blade in the kerf and check
that the saw teeth are not engaged into the
material. If the saw blade is binding, it may
travel up from the workpiece or kickback as
the saw is restarted.
• Support large panels to reduce the risk
