4.3 Limits for use, space, life.
The machine has been designed and
built for use on open-air
construction sites, according to the
climate conditions with reference to the
previous paragraph (4.2). The machine
must never be used in underground
excavations, in areas at risk for
explosions or fires, in closed places.
The machine is designed for preparing
and mixing concrete: sand, pebble
gravel, cement, water and for use on
construction sites only.
Ensure the areas of respect of the machine according to the TECHNICAL CHARACTERISTICS;
CAUTION !!!!!!
Every use of the machine different than those stated by the manufacturer in this instruction
manual is an improper use. Therefore, the company SILLA cannot accept any responsibility, if the machine
should be used by the operator for different uses then those listed in this instruction manual or those not complying
with the operating instructions.
4.4
Noise
The following table informs on: A
– weighted sound pressure level at workstations (LpA).
- weighted sound power level emitted by the machinery (LwA).
The values take into account the uncertainty
equal to 3dB and were collected in the
following conditions:
Material being processed :
Sand maximum grain size 3mm, degree of humidity between 4 and 10%.
Operating conditions :
Machine complete with all parts and ready to ship.
Load of the machine :
Equal to the output capacity indicated in the promotional material.
Observation period :
1 minute for each measurement.
Measuring instrument :
Sound-level meter
Delta Ohm s.r.l. model HD2010UC serial number 08052941513.
Calibration :
Centro SIT n°124 Delta Ohm s.r.l. n° certificate F0527_10 of 07/07/10.
Wind-shield :
Spherical, sponge.
In order to not increase the noise level, strictly follow these rules:
Clean and grease the machine elements according to the maintenance schedule;
Ensure the machine parts are not obstructed or damaged.
With this noise emission level the use of protective equipment like earmuffs, earplugs, etc. is mandatory.
These noise values are emission levels and not necessarily safe working levels. While there is a correlation between
the emission levels and the exposition levels, it cannot be used in a reliable way to evaluate whether there is or no r the need
for additional precautions. The factors affecting the worker’s real exposition level include the duration of the exposition, the
environmental characteristics, other emission sources like for example the number of adjacent machines and types of
machining. The single exposition levels may also differ from country to country. However, thanks to this information the user
of the machine can better evaluate the dangers and risks.
