5.4 SAFETY RECOMMENDATIONS FOR THE CORRECT USE OF
SUPERABRASIVES
General. Superabrasives are breakable and shall therefore be handled with utmost care! The use
of damaged or improperly mounted or used superabrasives is dangerous and can cause serious
injuries.
Delivery, handling and storage. Superabrasives shall be handled and transported with care.
Superabrasives shall be stored in such a manner that they are not subjected to mechanical
damages and harmful environmental influences.
Selection of superabrasives. Information on the label or the superabrasive as well as restrictions
of use, safety indications or any other instruction shall be followed. In case of doubt concerning the
selection of superabrasives, the user shall request information from the manufacturer or supplier.
Visual inspection and ring test. Superabrasives shall be subjected to a visual inspection as
received before mounting. In a addition, a ring test shall be executed for superabrasives with
vitrified core and abrasive section and D>80mm. Damaged superabrasives shall not be used.
Mounting, before starting and information for grinding. The mounting of superabrasive shall
be carried out according to the instructions provided by both, the superabrasive and the machine
manufacturer. Special attention shall be drawn to the fact that mounting of superabrasives is to be
carried out by a qualified trained person. Each time after mounting, the superabrasive shall be test
run for a reasonable time – the specified maximum operating speed of the superabrasive shall not
be exceeded.
Further information. The following instructions shall be observed, supplementary to the
information of the grinding machine:
– Observance of the user’s information of grinding machine manufacturer.
– Before starting, safety devices shall be mounted to the machine.
– No grinding operations without protection by safety devices.
– Use of personal protective equipment according to the type of machine and type of application,
e.g. eye and face protection, ear protection, respiratory protection devices, protective footwear,
protective gloves and other protective clothing.
– Only grinding operations for which the superabrasive is suitable shall be carried out (taking into
account restrictions of use, safety indications or other information).
– In the case of cutting-off with hand-held grinding machines, the superabrasive shall be placed
in the cutting gap in a straight position. Jamming of the hand-held grinding machine shall be
prevented.
– Before placing the hand-held grinding machine on the workbench or on the floor it shall be
turned off and it shall be ensured that the abrasive product has stopped.
5.5 RESIDUAL RISK
Important: Although the safety instructions and operating manuals for our tools contain extensive
instructions of safe working with power tools, every power tool involves a certain residual risk
which can not be completely excluded by safety mechanisms. Power tools must therefore always
be operated with caution!
