3.4 Noise level
Sound Pressure Level < 80.4dB(A) < 85.7dB(A)
Sound Power Level
Associated uncertainty K = 4 dB
Measurement made in accordance with EN ISO
3746:1995 and EN ISO 11202:1995
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, ear-
plugs,...)
Please always use the hearing
protection systems.
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.The related pressure
drop at the dust port is 530 Pa.
Upper hood
Air flow 140 cu.m/h
Minimum air speed 20 m/s
Ensure that the suction system guarantees these values
at the hood-houth connection point. (Fig.3.5)
No load Load
< 98.1dB(A) < 100.7dB(A)
Saw
Lower hood
690 cu.m/h
Suction mouth diameter:
A. Blade guard ...... ø40 mm
B. Body dust suction ...... ø100 mm
Connect the mouths to the suction system with flexible
tubes of adequate diameter. Tighten with clamps. The
tube must be positioned in such a way so as not to
obstruct the operator during machining.
Always work with the suction system on. Always start
the suction system and the machine at the same time.
3.6 Safety devices
The machine is equipped with the following safety
devices: (Fig.3.6)
A
A. Safety Switch.
Stops the machine if the guard D is opened to perform
operations on the blade.
