2.1.3 POSITION OF THE NOISE PLATES
ON MACHINES WITH CANOPY
q
The noise plates must always be legible and in good conditions;
for this reason, if they are dirty with dust, oil or grease, it is nec-
essary to clean them with a solution made of water and deter-
gent.
Do not use fuel, petrol or solvents.
q
If the plates are damaged, ask for new ones to Komatsu or to
your Komatsu Distributor.
q
In case of replacement of a component provided with a noise
plate, make sure that such a plate is applied also to the new
part.
EXTERNAL NOISE
q
Sound power level emitted by the machine, measured accord-
ing to ISO 6395 (Dynamic test method, simulated working cy-
cle).
This is the guaranteed value as specified in European directive
2000/14/EC. This value includes an uncertainty-of 0.5 dB.
NOISE PERCEIVED BY THE OPERATOR
q
Sound pressure level at the operator’s station, measured ac-
cording to ISO6396 (Dynamic test method, simulated working
cycle).
The maximum value of the standard deviation of the measured
time-averaged A-weighted emission sound pressure level at the
operator’s position is 0.8 dB, in accordance with ISO 11201.
