Electrical Connection; Noise Level; Dust Extraction - LEMAN SST256 Manual De Instrucciones

3.3 ELECTRICAL CONNECTION

- Electrical installation should be carried out by
competent, qualified personnel.
- The mains connection should be made using the
terminal box.
- Replacement of the power supply cable should only be
done by a qualified electrician.
WARNING
To avoid electrocution or fire, any maintenance or repair
to electrical system should be done only by qualified
electricians using genuine replacement parts.

3.4 NOISE LEVEL

Sound Pressure Level
Sound Power Level
The noise levels measured are emission levels and not necessarily the safe working level. Although there is a
correlation between the emission levels and the exposure levels, this cannot be used reliably to determine whether or
not further precautions are required. The factors which affect the actual level of operator exposure include the duration
of exposure, the ambient characteristics and other sources of emission, for example, the number of machines and
other adjacent machining. The permitted exposure values may also vary from country to country. Nevertheless, this
information allows the user of the machine to better evaluate the dangers and risks.
Other factors which reduce exposure to noise are:
- correct tool choice
- tool and machine maintenance
- use of hearing protection systems (e.g. headsets, earplugs,...)
WARNING

3.5 DUST EXTRACTION

Proper suction eliminates the risks of dust inhalation and
aids better functioning of the machine. The tables list the
minimum air flow and speed values referenced to each
single suction operation.
No load
< 80dB(A)
< 90dB(A)
Please use the hearing protection systems if the above mentioned noise levels
exceed 95dB(A).
Load
< 90dB(A)
< 100dB(A)
