The SMD 133 DRE grinding machine is constructed according to the state of the art and
recognised technical safety rules. However, during its use, danger for persons and property
damage can occur.
The machine is to be used only for intended use in technically faultless condition and in
observance of safety instructions.
2.2 Organisational measures
Personnel authorised to work on the machine must have read and understood the operating
manual before starting work. This applies notably to personnel who only work occasionally on the
machine, e.g. for changeovers and service.
The operating manual is to be kept permanently at the machine location and easily accessible.
Perform checks for safe and hazard awareness work by operators while following the operating
manual.
If necessary or required by country-specific regulation, use personal protective clothing (e.g.
work gloves, safety glasses, hearing protection).
Observe all safety and danger instructions on the machine.
Keep all safety instructions and danger warnings on the machine complete and in legible
condition.
No changes, removal or addition of parts to the machine without the written approval of the
manufacturer.
Only use original replacement parts from the manufacturer.
Keep intervals for service work which are given in the operating manual.
2.3 Personnel selection and qualifications
Only authorised personnel of legal minimum age may work on the machine.
Personnel who are being trained or orientated on the machine may only work on the machine
under continuous supervision of an experienced person.
Only use trained or orientated personnel. Clearly establish responsibilities of the personnel for
operating, maintaining and servicing.
Establish a machine operator responsibility. The machine operator must refuse to follow
instructions that are contrary to safety.

Safety
Grinding machine SMD 133 DRE /-60 9
2.4 Transport
Only use lifting gear and load carrying equipment with sufficient lifting capacity during loading
work (see Technical Data for weights).
Name an expert instructor for the lifting process.
Only lift the machine properly with the lifting gear according to instructions in the operating
manual. Only use the provided attachment points for the load carrying equipment.
Only use suitable transport vehicles with sufficient load capacity.
Reliably secure the machine during vehicle transport. Use suitable attachment points.
Perform recommissioning after transport only according to the operating manual.
2.5 Normal operation
Before beginning work become familiar with the operating location and working environment.
The work environment includes, for example, work area obstructions and assistance options in
case of accidents.
Only operate the machine in a safe and functional condition.
Refrain from working in any manner that is questionable in regard to safety.
Immediately stop and secure the machine in case of malfunctions. Immediately correct
malfunctions.
At least once per shift (display indication Fault messages) check the machine for externally
recognisable damage and deficiencies. Report any changes occurring (including operating
behaviour) to the responsible department or person. If necessary, immediately stop the machine
and secure it.
2.6 Maintenance, Service and Troubleshooting
Adjustment, maintenance and service work may only be carried out by authorised technical
personnel.
Perform adjustment, maintenance and service work according to instructions in the operating
manual. Keep the specified intervals for service work.
Inform operating personnel before beginning adjustment, repair, or maintenance work. Name a
supervisor.
Always disconnect the machine from electrical power during maintenance and repair work
(main switch in the 0 position).
When the machine is being cleaned of material residues, always disconnect the machine and
the extraction system from the mains supply.
Before cleaning with cleaning agents, close all openings with suitable materials in which no
water or cleaning agent can penetrate, for safety or functional reasons. Electric motors and
switches are especially at risk.
Do not perform any cleaning with high pressure cleaners.
Openings which were sealed before cleaning, must be completely opened after cleaning.
Always tighten loosened screw connections with the specified tightening torques during
maintenance and service work.
If safety equipment is dismantled during changeover, maintenance, service and repair, remount
and check the safety equipment immediately after the work is completed.
Dispose of operating and auxiliary materials and replacement parts safely and in accordance
with country-specific regulations.

2.7 Safety instructions for special types of dangers
2.7.1 Electric power
Work on the machine's electrical systems may only be carried out by electricians according to
the rules of electronics.
In case of problems with the electrical power supply, turn the machine off immediately.
When changing fuses only use original fuses with specified amperage.
Regularly check the machine electrical equipment. Immediately correct deficiencies, such as
loose connections or scorched cable.
2.7.2 Dust
The machine may only be operated with a working dust extraction system compliant with
country-specific regulations (e.g. EC Directive) and approved for steel dust.
If carcinogenic substances are released during grinding (e.g. with stainless steel), the exhaust
system must be operated with an absolute filter.
The machine must be connected to a dust extraction system with wet extraction when grinding
aluminium.
Follow the operating manual of the exhaust system!
All federal requirements for extraction systems for potentially explosive steel dusts must be
met.
It must be guaranteed that the continued operation of machine is impossible if the dust
extraction system fails.
The volume flow rate of the dust extraction system must be at least 3000 m³/hr.
The flow velocity must be at least 20 m/sec.
No dust deposits should form in the extraction pipes.
2.7.3 Fire hazard
Do not process any workpieces which have been treated with a flammable corrosion resistant
agent or flammable additive.
Do not operate the machine near easily flammable materials.
Make sure that the machine is always cleaned of machining residues according to the operating
manual.

Safety

2.7.4 Explosion hazard
2.7.4.1 Description of explosion hazard
Do not process aluminium or aluminium alloys on the machine. The machine has no explosion
protection and is not approved for the processing of aluminium.
Clean the slag capture boxes of scrap material and slag residues daily
2.7.4.2 Division of zones
The extraction of the steel dust with a suitable extraction system (see Section 2.7.2) and
performing the cleaning intervals (see Section 6.4) prevents the formation of an explosive
atmosphere within the machine or in the suction pipes.
Only if this is ensured may the machine be operated.
