3.3 Safety devices
The machine is equipped with all the necessary
safety devices to protect against operating risks
that could not be eliminated by its design. These
safety devices include, in particular:
– For a max. tool diameter of 400 mm:
Top safety hood fitted separately from the
riving knife for max. saw blade diameter of
400 mm, available in a narrow and a wide for-
mat made of polycarbonate to optimally cover
the section of the blade not required for sawing
above the machine table with a safeguard
against lifting beyond the maximum cutting
height of + 5 mm. Rollers integrated in the safe-
ty hoods at the leading and trailing ends make
it easier both for feeding workpieces and for
pulling back of workpieces if workpieces have a
slightly different thickness.
– 3 riving knives for saw blades between 250 and
400 mm diameter to avoid workpiece kick-back
as a result of jamming in the cutting line.
– Rip fence with straight edge adjustable in the
cutting direction. Can be pulled back to prevent
parts of crosscut workpieces from jamming
between the fence and the rising gear rim, or
can be switched over to a low guide surface for
cutting narrow and flat workpieces, allowing
adequate space for the guide hand together
with the possibility of lowering the top safety
hood onto the workpiece here, too.
– Trimming hold-down to clamp and hold down
untrimmed solid wood to secure against
slippage in the course of trimming.
– Sliding table arresting device to prevent
workpiece kick-back for insert cuts together
with the cross-stop.
– Electrical interlocking of the cover plate on the
extraction duct beneath the machine table in
the vicinity of the saw blades. It is not possible
to switch on the machine when the cover plate
is open, and if the cover plate is opened while
the machine is running, the drives will switch
off.
– Automatic brake which, after switching off,
brings the main saw blade to a standstill in less
than 10 seconds, regardless of the saw blade
diameter and rotational speed.
– Favorable airflow design of the lower extraction
duct and the top safety hood to reduce dust
emission to below 2 mg/m³, providing that the
machine is connected at both extraction
sockets to an extraction system having a min.
airspeed of 20 m/s.

– Ergonomic arrangement of the operating
elements at readily accessible positions at the
machine frame.
