Dust/chip extraction (see figure H)
The dust from materials such as lead paint, minerals and
metal can be harmful to human health. Touching or breath-
ing in this dust can trigger allergic reactions and/or cause
respiratory illnesses in the user or in people in the near vicin-
ity.
Certain kinds of metal dust are hazardous, especially in com-
bination with alloys such as zinc, aluminium or chrome. Ma-
terials containing asbestos may only be machined by special-
ists.
– Provide good ventilation at the workplace.
– It is advisable to wear a P2 filter class breathing mask.
The regulations on the material being machined that apply in
the country of use must be observed.
The saw blade (31) can become blocked by dust, chips or
workpiece fragments in the recess of the saw table (25).
– Switch the power tool off and pull the mains plug out of
the socket.
– Wait until the saw blade has come to a complete stop.
– Pull out the chip drawer (24) and empty it completely.
Avoid dust accumulation at the workplace. Dust can
u
easily ignite.
Starting operation
Pay attention to the mains voltage. The voltage of the
u
power source must match the voltage specified on the
rating plate of the power tool.
Products that are only sold in AUS and NZ: Use a resid-
u
ual current device (RCD) with a nominal residual current
of 30 mA or less.
Position of the operator (see figure I)
Do not stand in line with the saw blade in front of the
u
power tool. Always stand to the side of the saw blade.
This protects your body against possible kickback.
– Keep hands, fingers and arms away from the rotating saw
blade.
