Noise emissions
The noise specifications in the technical data
were determined according to CEN stan-
dard "Noise measurement of industrial trucks,
sound level at the workplace and sound power
level" (in preparation). The sound power level
at the driver’s station is 65 dB(A).
According to directive 86/188/EEC, however,
the specified truck noise levels cannot be
used for determining the noise emission at the
workplace (daily personal noise allowance).
If required, these must be determined directly
at the workplace under actually existing in-
fluences (further sources of noise, special
operating conditions, sound reflections).
Frequency characteristics
The machine frequencies were determined on
an identical machine in accordance with EN
13059. "Safety industrial trucks. Test meth-
ods for measuring vibration".

Studies have shown that the frequency of
hand and arm vibrations at fork truck steering
wheels or controls is under 2.5 m/s². For this
reason no test specifications are available for
these measurements.
The personal vibration load on the driver for
one work day must be determined, if neces-
sary, at the site of operation in order to take all
other influencing factors such as road stretch,
intensity of operation, etc., into consideration.
Battery emissions
During charging, the drive battery emits a mix-
ture of oxygen and hydrogen (detonating gas).
This gas mixture is explosive and it must not be
