N
Checking the tightening of the drive belt with the „frequency-test"
Checking with measuring device for belt tension [cos14863]:
N
Switch off the running machine at the main switch.
N
Visual inspection of the drive belt for abraison and
correct fitting.
N
Switch on the tuning device.
N
The tuning device must be in mode „BASS",
change with button GUITAR/BASS.
N
Hold the tuning device with the microphone (MIC)
close to the bottom trumm of the drive belt and
pick the trumm (see picture).
N
The tension of the drive belt at the bottom trumm
(see picture) needs to be between 98 Hz and
103 Hz (frequency during swinging).
N
Check the tone in the display: Target = 1G – adjust the tension of the drive belt if necessary.
N
Check the amplitude of the needle: Target 440 ... 460 – adjust the tension of the drive belt if necessary.
N
When the tuning device is indicating the tone 1G and an amplitude of the needle of 440 ... 460 the tension of
the drive belt is ok.
Chart with tones to the according frequency:
target value frequency drive belt
X

X
The target value of the frequency is between 98Hz and 102Hz. This is equal to the tone 1G. If the result of the test
is out of this area, the tension of the drive belt must be adjusted.
frequency < value 98: belt tension need correction.
frequency > value 102: belt tension need correction.
After changing the tension of the drive belt new check is necessary.
