operations, the rear of the machine moves slightly
outward: reduce the speed to avoid brusque direction
changes and impacts against walls or other objects.
Use the brake to stop the machine.
To avoid damage to the surfaces being treated, the
brush motor will stop automatically about 2 seconds
after the advancement pedal has been completely
released.
When moving in reverse, the squeegee will lif t and
suction will be deactivated automatically. After changing
direction (forward direction), the squeegee and the
suction will automatically return to their previous
condition.
Never use the machine without the detergent
solution: the floor might be damaged.

8. MAINTENANCE INFORMATION

Turn the key, remove it from the control panel and
disconnect the battery from the machine wiring.
All work on the electrical system as well as all
maintenance and repair operations (especially those
not explicitly described in this manual) should be carried
out only by authorised service centres or by specialised
technical personnel who are experts in the sector and
in the pertinent safety regulations.
Performing regular maintenance on the machine, and
carefully following the manufacturer 's instructions, is
the best guarantee for obtaining the best performances
and extended machine service life.

8.1 TANKS

Drain the two tanks as described in the relative sections.
Remove any solid dirt by filling and draining the tanks
until all dirt has been eliminated: use a washing hose
or similar tool to do this.
Water hotter than 50°, a high-pressure cleaner or
excessively powerful sprays may damage the t anks
and the machine.
Leave the covers of the t anks open (only while the
machine is not being used) so that they can dry and
thus prevent the formation of foul odours.
8.2 SUCTION HOSE
During these Unscrew the knobs of the rear blinker holder pocket.
