Make sure that your operation does not create a safety hazard.

Disconnecting and securing the grinding machine
Disconnect the mains plug before starting maintenance and repairs.
1.12
Emissions
The generation of noise emitted by the grinding machine is 70 to 80 dB(A). If the grinding
machine is installed in an area where various machines are in operation, the noise exposure
(immission) on the operator of the grinding machine at the working place may exceed 80 dB(A).
INFORMATION
This numerical value was measured on a new machine under the operating conditions specified
by the manufacturer. The noise behaviour of the machine might change depending on the age
and wear of the machine.
Furthermore, the noise emission also depends on production engineering factors, e.g. the used
material.
INFORMATION
The specified numerical value represents the emission level and does not necessarily a safe
working level. Though there is a dependency between the degree of the noise emission and the
degree of the noise disturbance it is not possible to use it reliably to determine if further precau-
tion measures are required or not. The following factors influence the actual degree of the noise
exposure of the operator:
Characteristics of the working area, e.g. size or damping behaviour,
other noise sources, e.g. the number of machines,
other processes taking place in proximity and the period of time, during which the operator
is exposed to the noise.
Furthermore, it is possible that the admissible exposure level might be different from country to
country due to national regulations. This information about the noise emission should, how-
ever, allow the operator of the machine to more easily evaluate the hazards and risks.
CAUTION!
Depending on the overall noise exposure and the basic threshold values, machine
operators must wear appropriate hearing protectors. We generally recommend the use
of noise and ear protection.

Basic information on grinding wheels
Various shortcomings during installation and operation can lead to the bursting of grinding
wheels.
Ordinary grinding wheels are generally not designed to withstand a greater lateral load.
The tapping off cutting debris from the grinding wheel always leads to damage of the grind-
ing wheel.
Grinding wheels which have an imbalance can burst more easily.
An unbalance of a grinding wheel cannot be completely removed by trueing with a diamond
dresser.
Incorrectly stored grinding wheels can burst immediately after switching on, or individual
small fragments can fly away like a bullet.
