CENTRAL BRUSH ADJUSTMENT
AND REPLACEMENT
Warning: these operations must be carried
out with the machine off, the key switched
off (for battery-operated version), selector
in "OFF" position (for petrol-operated ver-
sion) and with the machine on even floor.
When the main brush is fairly worn, its height
must be adjusted to recover as much of the
brush consumption as possible.
Loosen the knobs "
A
" on both sides of the
machine, lower the brush to the ground taking
the "
B
" indicator to the right position in the di-
rection shown in the figure. The "
B
" indicator
must be placed in the same position on both
sides of the machine.
To make sure that the main brush has been
properly adjusted, perform the following opera-
tions: let the brush rotate with the machine not
in operation and on a flat ground; then make
sure that the print left by the brush onto the
ground is from 2 to 4 cm. wide.
If the brush does not operate efficiently repeat
the adjustment operation.
When the brush is completely worn-out, it must
be replaced.
In order to perform this operation, just lift the
bonnet so as to disconnect the safety device;
loosen the knob on the left side of the machine,
as shown in the figure.
Remove the cover by pushing it down.
