2.3 Organizational measures
The user guide is to be kept near the location where the machine is being operated and must be
within reach at all times.
In addition to this user guide general and legal regulations regarding accident prevention and
environmental protection must be complied with as per local regulations.
Such duties may, for example, relate to the handling of hazardous substances, or to the
provision and wearing of personal protection equipment, as well as compliance with traffic
regulations.
The user guide must be supplemented by other instructions, including the duty to supervise
and report incidents relating to particular working practices, for example work organization,
work procedures and personnel safety.
Personnel entrusted with working with the machine must read the User Guide before starting
work, in particular the “2Safety Regulations” chapter. To read these instructions after work
is commenced is too late. This particularly applies to incidental activities such as setting up
the equipment, carrying out maintenance work or training staff to work with the machine.
From time to time the working practices of the operators are to be checked by a supervisor
especially to the items regarding awareness of safety and hazards.
Operators must tie back long hair, and not wear loose clothing or jewelry including rings.
There is a risk of injury through items getting caught, or being drawn into moving
machinery.
Eye and ear protection must be worn at all times!
Use personnel protection equipment if necessary or required by local regulations! Take
notice of all safety and hazard notices on the machine!
All safety and hazard notices at or on the machine must be kept complete and legible!
If safety-critical changes occur to the machine or its working method, the machine must be
shut down immediately! The cause of the fault must be established, and rectified.
Changes, add-ons or conversation to the machine, which might impair safety, must not be
made, without the manufacturer’s permission!
This applies in particular to the fitting and adjustment of safety devices.
Spare parts must comply with the technical requirements specified by the manufacturer. This
is always guaranteed if original spare parts are used.
Intervals for recurring checks and inspections specified in this User Guide must be complied
with!

Only use extension cables that are sized and marked in accordance with the overall power
consumption of the machine and the valid VDE guidelines.
See “2.6 Electrical safety” for further information.
Make sure there is no debris in the work area.
Check the work area for screws or other hard objects in the concrete. Don’t use the machine
if there are any foreign objects stuck into the surface. Such objects must be removed prior to
operation of machine
2.6 Electrical safety

The work area must be secured against any third party
entering the work area. Follow local electrical engineering regulations while working on the
machine. Never leave a machine unattended. Use only tools that are insulated against
electricity.
Only start work after you are familiar with the electrical engineering regulations that apply
to the local area.
Only use voltage seekers that comply with the regulations when troubleshooting. From time
to time check voltage seekers to ensure that they are operationally efficient.
2.6.1 Cables
Only use cables that are marked and rated according to the specifications in “1.1 Electrical
specifications”. Don’t use excessive length of the cables. If a very long cable is needed
we recommend that you use a cable rated for more current and connect it to a distribution
central near the machine. Never lay the cable in a loop when operating the machine, this will
cause the cable to heat up and may cause fire. See “Figure 2-1” for explanation.
Figure 2-1 Recommended way to handle excessive cable length.
2.6.2 Using a generator
The generator must be equipped with protective earth and operated in accordance with the
current EN-VDE directives (this applies to the protective earth conductor in particular) in
order to ensure that all safety devices are functioning and eliminate possible damage to
electrical components.
2.7 Definition of the “Safety off position”
The machine is in a safe condition where it cannot be any hazard.
How to set the machine in the Safety off position:
1. Switch off the machine
2. If a dust collector is used, switch it off
3. Wait for all drives to come to a complete stop
4. Disconnect the main power
5. Secure against unintended restart
Always disconnect the main power at the machine end to be able to prevent other persons
from accidentally reconnect the main power while working on the machine.
