2 - SAFETY INFORMATION
Noise emission
The measuring and reporting of the noise level were car-
ried out according to
ISO 5131 .
The noise is measured with the engine and all mecha-
nisms engaged and running at normal operating speed
for the specified use of the product. These are maximum
values which in normal operating conditions will never be
exceeded.
The measurement of the noise level took place in the trac-
tor cabin, where usually is the head of the operator.
To enable measurement of noise level at the operator seat
produced by the tractor - implement combination, it must
be noted that the airborne noise produced by the imple-
ment attached to the tractor is measured at a distance
of
200 mm ( 7.9 in ) behind the rear window position of an
average tractor suitable for operating the implement.
Two measurements were carried out, both with the Rev-
olutions Per Minute (RPM) of the tractor engine adjusted
so that the Power Take-Off (PTO) runs at
540 RPM :
• Implement connected, tractor window closed:
76.5 dB .
On tractors with cab provided all windows, doors and
other possible openings are kept closed; it is obvious that
the real noise level at the operator's seat will be signif-
icantly lower. The exact level will depend on the noise
insulation qualities of the cab.
On tractors without a cab or when you work with the cab
doors or windows open, it is recommended to use ear pro-
tection equipment when the noise level exceeds 90 dBa.
In several countries this is mandatory, so check local leg-
islation.
Always use hearing protectors if the noise from the imple-
ment is annoying or if you work with the implement for a
considerable period in a tractor that has not an adequate
soundproof cabin.
NOTICE: The level of noise for the operator could be less
or greater depending upon the towing tractor.
Vibration levels
All revolving parts are balanced by means of a special
machine with electronic sensors. If a part still has an un-
balance, small counterweights must be fastened.
As the discs run at up to 3000 RPM , even the slightest
unbalance will cause vibrations which may lead to fatigue
fractures.
NOTE: If the vibrations or the noise of the implement in-
crease considerably during the operation, stop the work
immediately. Correct the fault before you continue the
work.
NOTE: When you replace the blades, replace both the
blades on the disc in question not to create an unbalance.
