The first row of the display (lsp) gives the draw of the brush motors. To obtain the correct draw value, wait a
few minutes with the motors turning until the value stabilises.
22
After a few minutes, the display shows the stabilised brush motor current draw value without load, without
the brushes (in this case lsp = 5.3 A) .
23
Now perform a wash cycle with the brushes mounted following the instructions above.
24
Remount the brushes on the head: place the brushes under the head, centring is automatic. Press the brush
attachment button F. The LED G will flash and the machine will form a release operation without the brushes
attached. At the end of this, press the button F again, LED H flashes and the machine performs the brush
attachment operation.
25
Move the machine to a relatively smooth area of floor in order to obtain a constant reading.
26
To avoid wasting water, press the "+" and "-" buttons D to set the quantity of water to minimum, one LED on
only (3.0 - 5.0 litres/minute). This is sufficient to wet the floor and avoid overheating the brush bristles.
27
Press the manual brush button E to operate the brushes
28
Read both draw values, lsp (brush motor draw during the washing phase) and Tara (brush motor draw
without load, with the brushes mounted but before they touch the floor).
29
Compare the values against the table below.
30
Check brush motor draw with a clamp meter (following paragraph) or restore the modified values to the
previous default values.
Important: set maximum pressure during testing
