PARKING BRAKE
The machine is equipped with a parking brake on the
traction wheel which releases when the traction motor

MANUAL MOVEMENT OF THE MACHINE
To move the machine manually, it is necessary to un-
block the parking brake that blocks the traction motor
wheel. To do this, keep the lever (3) lifted. With the
delivery of the machine we also supply a cord that al-
lows the lever operation (3).
After having moved the machine, take off the cord and
keep it for eventual re-use.
When the parking brake is released manually, for ex
-
ample when the machine has to be moved without bat-
teries, avoid covering slopes and do not park on them.
BRUSHES MOTOR OVERLOAD PROTECTION
SYSTEM
The machine is equipped with a protection device of
the brushes motor. This device blocks the motor func-
tioning in order to protect it and indicates the overload
on the display with the message "ALLARME 1".
When this happens, try to reduce the brushes pres
-
sure (see under "ADJUSTMENT OF THE BRUSHES
PRESSURE").
If the problem persists, contact the authorized techni-
cal assistance.
OVERFLOW SYSTEM
In order to avoid serious damages to the suction motor,
the machine is equipped with a float that intervenes
when the recovery tank is full. When this happens,
it is necessary to empty the recovery tank. Hold the
exhaust hose of the machine. Take off the plug and
empty the recovery tank into appropriate containers,
according to the standard norms.
