Disconnecting and securing the grinding machine

Unplug the mains switch before starting any maintenance or repair work.

Emissions

The noise emitted by the grinding machine is less than 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 drilling 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 its age
and wear.
Furthermore, the noise emission also depends on production engineering factors, e.g. speed,
material and clamping conditions.
INFORMATION
The specified numerical value represents the emission level and does not necessarily consti-
tute a safe working level. Although 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 deter-
mine, if further precaution measures are required or not. The following factors influence the
actual degree of noise exposure for 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,the admissible exposure level might differ from country to country due to national
regulations. This noise emission information should, however, allow the machine operator to
more easily evaluate the hazards and risks.
CAUTION!
Depending on the overall noise exposure and basic threshold values, machine operators
must wear appropriate hearing protection. We generally recommend the use of noise
protection and hearing 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.
