2.7 Residual risks
The machine has undergone a hazard analysis. The design and construction of
the machine are based on the results of this analysis and correspond to state-of-
the-art technology.
The machine is considered operationally safe when used properly. Even if all of
the safety measures are complied with, there are still certain associated risks that
must be considered when working on the machine:
Improper operation of the machine
Serious injuries
●Work on the machine may only be carried out by authorised, trained per-
sonnel who are familiar with how to operate the machine and are in strict
observance of all safety instructions.
●If possible, only perform work when the machine is disconnected from all
energy sources and an unintentional restart is prevented.
●The machine has to be switched off when carrying out any work on the
machine.
●Disconnect machine from power supply before carrying out work at elec-
trical devices.
●Do not deactivate or bypass protective devices.
Missing personal protective equipment
Serious injuries
●Wear suitable personal protective equipment.
Pointy tools and sharp objects
Cuts and stab wounds
●Use protective gloves.
Dust-emitting activities
Beech- and oak wood dust are classified as carcinogenic. The dusts of other
woods are under suspicion to be carcinogenic. Dust-emitting activities can cause
severe health damage.
●Use dust mask during dust-emitting activities.
●Use low-dust cleaning methods.

12
Safety instructions
Disorder at the workplace
Loose objects or objects that are lying around can cause severe injuries.
●Ensure that there is sufficient space to work around the machine.
●Remove loose objects from the working area.
●Keep the work area orderly and clean.
Insufficient lighting of the installation room
Serious injuries
●Light installation room sufficiently.
Standing on the machine
The covers or projecting components of the machine are not suitable for standing
on them. If the machine falls down, severe breaks can occur.
●It is forbidden to climb onto the machine.
Noise pollution by machine operation
Severe hearing damage
●Use hearing protection.
Decommissioned safety devices
The machine is equipped with diverse protective devices with safety function.
When protective devices are decommissioned, the safety function is no longer
ensured. Decommissioned safety devices can cause severe injury.
●Do not deactivate or bypass protective devices.
Foreign bodies in the materials to be processed
Foreign bodies in the materials to be processed can cause sparks, which can lead
to fire. These fires can cause severe burns or smoke poisoning.
●Use high-quality materials.
●Remove dust deposits in the machine and in the production area daily.
Disruption of the energy supply
The disruption of the energy supply can cause workpieces to rotate longer than
the largest deceleration time. This can cause cuts or severed limbs.
●Wait for all parts to be still.
●Disconnect machine from all energy sources and secure against restarting.
Damage to electrical components or their insulation
Damaged electrical components or damage to their insulation cause deadly elec-
tric shocks.
●Work on electrical fittings may only be carried out by qualified personnel
and in strict observance of the safety instructions.
●Disconnect machine from power supply and secure against restarting before
carrying out work at electrical devices.
