Noise and vibration information
Noise emission value may be exceeded.
Vibration emission value may be exceeded.
Select tools correctly and replace them promptly when they
show wear.
Maintenance may be carried out by trained specialist techni-
cians only.
Establish additional safety precautions for the protection of
the operator against the effects of vibrations (e.g. keeping
hands warm, organizing the work sequences, machining with
normal feed power).
Vigorous upward and downward movements (hammering)
due to unsuitable die.
Excessive tool wear and increasing loads on the machine.
Ø
Use dies with the greatest height possible (keep distance X,
shown in the drawing below, as small as possible).
Notes
■
The specified vibration emission value was measured in
accordance with a standardized testing procedure and can
be used to compare one electric tool with another.
