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.
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.

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) 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.

Safety
Grinding Machine SBM-L 1000+1500 G1S2ALU MIX 11
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 surveillance person.
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.

Grinding Machine SBM-L 1000+1500 G1S2ALU MIX 12
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 cables.
2.7.2 Dust
The SBM-L 1000+1500 G1S2 ALU MIX grinding machine may only be
operated according to country-specific regulations (e.g. EU regulations)
and is permitted for steel and aluminium dust.
If carcinogenic substances are released during grinding (e.g. with
stainless steel), the exhaust system must be operated with an absolute
filter.
Comply with operating manual for dust extraction.
All federal requirements for dust extraction systems for potentially
explosive dusts must be met.
It must be guaranteed that the continued operation of the grinding
machine is impossible if the dust extraction system fails.
The volume flow rate of the dust extraction system must be at least
2200 m³/hr.
The flow velocity must be at least 20 m/sec.
No dust deposits should form in the extraction and fixed 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
Grinding Machine SBM-L 1000+1500 G1S2ALU MIX 13
2.7.4 Explosion hazard
2.7.4.1 Description of explosion hazard
The machining of aluminium produces flammable dust by grinding
that, when mixed with air, can form a potentially explosive
atmosphere. This also applies to the machining of steel and stainless
steel.
In a mixture of aluminium and steel dust, explosive gas can be
produced from corrosion.
2.7.4.2 Division of zones
The extraction of the aluminum or steel dust with suitable extraction
systems (see 2.7.2) and performance of the cleaning intervals (see
7.4+7.5) prevents the formation of an explosive atmosphere within the
machine or in the suction pipes. If these requirements are not
observed precisely, there is also no explosion protection for the
operator. Only if the dust load in the air is below 30g/m3 , can the
interior of the machine and the suction pipes be considered a zone
not threatened by explosion.

Safety
Grinding Machine SBM-L 1000+1500 G1S2ALU MIX 14
2.8 Symbols on the machine
The following symbols are located on the machine and warn of dangers
coming from the machine:
Symbol Meaning
This symbol on both conveyor belts indicates the danger that hands or body parts
can be pulled in and sheared off.
This symbol on the control cabinet indicates dangerous electrical voltage.
Risk of shearing from moving part
Read the operating manual and follow the information in the operating manual.
Wear protective gloves when placing and removing workpieces.
Wear hearing protection when working on the machine.
Wear safety glasses when working on the machine.
Lubrication point
The symbol indicates the minimum length of the workpiece to be machined.
Running direction
Transport with crane possible.
Transport with forklift possible.
Safety strips are attached at various locations in the machine. When these safety
strips are covered with grinding dust the machine must be thoroughly cleaned. This
should prevent the collecting of grinding dust.
