Starting Operation
Observe correct mains voltage! The voltage
of the power source must agree with the
voltage specified on the nameplate of the
machine. Power tools marked with 230 V
can also be operated with 220 V.
Switching On (see figure M)
– To start the machine, press the On/Off
switch 27 and keep it pressed.
Note: For safety reasons, the On/Off switch 27
cannot be locked; it must remain pressed during
the entire operation.
The locking lever 43 will only disengage the re-
tracting blade guard 10 after pressing button 8,
so that the tool arm can be lowered.
– For sawing, you must press button 8 in addi-
tion to actuating the On/Off switch.
Switching Off
– To switch off the machine, release the
On/Off switch 27.
Working Advice
General Sawing Instructions
For all cuts, it must first be ensured that the
saw blade at no time can come in contact
with the fence, screw clamps or other ma-
chine parts. Remove possibly mounted aux-
iliary stops or adjust them accordingly.
Protect the saw blade against impact and shock.
Do not subject the saw blade to lateral pressure.
Do not saw warped/bent workpieces. The work-
piece must always have a straight edge to face
against the fence.
Long workpieces must be underlaid or support-
ed at their free end.
Position of the Operator (see figure N)
Do not stand in a line with the saw blade in
front of the machine. Always stand aside of
the saw blade. This protects your body
against possible kickback.
– Keep hands, fingers and arms away from the
rotating saw blade.
– Do not cross your arms when operating the
tool arm.
