ing the breaker that tripped.
When the thermal breakers trip, especially when 43
the machine is used during the first few weeks, it
might not be caused by actual machine malfunctions.
However, a specialised technician should check the
device if the relative breaker continues to trip.
8.9 PERIODIC MAINTENANCE
For all the operations described in the following
scheduled maintenance table, refer to the instructions
and detailed warnings in the relative sections.
8.10 RECOMMENDED SPARE PARTS

machine (Photo A - 9).
9.2 PROBLEM SOLVING GUIDE
9.1 MALFUNCTIONS
SELF-DIAGNOSTIC
N° buzzer
Solution
01 TRACTION BLOCKAGE
Stops traction motor to protect from excessive current peak. To
restore, restart the machine.
02 MAX TRACTION TEMPERATURE Stops traction to protect the motor from excessive continuous
current. To restore, restart the machine after the motor has coo-
led down.
03 BATTERY SPENT
Stops brush, suction and traction motor due to battery voltage
insufficient. To restore, restart the machine after the battery
charging.
04 MAX ELECTR TEMPERATURE
Stops traction motor due to excessive temperature of the elect-
ronic control board unit. To restore, restart the machine after the
control board has cooled down.
05 BATTERY LEVEL TOO HIGH
Stops brush, suction and traction motor due to excessive bat-
tery voltage. To restore, restart the machine after having chec-
ked the battery.
06 ACCELERATOR PEDAL FAULT
Stops traction for incorrect communication with the potenti-
ometer (suspect detachment). To restore, restart the machine
after having checked the correct connection of the potentio-
meter.
07 ERROR TEMPERATURE
The traction speed is reduced according to the setted value of
the parameter RID_TEMP. To restore proceed at reduced speed
until the cooling of the electronic control board unit.
08 BATTERY LEVEL VERY LOW
Stops brush and suction motor due to battery voltage insuffi-
cient. To restore, restart the machine after the battery charging.
09 BATTERY LEVEL LOW
Stops brush motor due to battery voltage insufficient. To res-
tore, restart the machine after the battery charging.
10 TANK FULL
Stops suction motor because the recovery water tank is full. To
restore, empty the recovery tank.
11 START#BLOCKAGE”}
Stops traction as the accelerator pedal is pressed down when
turning on the machine or after braking, avoiding unwanted
movements of the machine. To restore, fully release the accele-
rator pedal.
