Problem
Possible cause
Remedy
The bead breaker roll is not im-
mediately activated.
1. Supply missed.
2. The operating push button/lever
is broken.
1. Connect the supply.
2. Call for technical assis-
tance.
The upper bead-breaker arm re-
mains down.
Compressed air supply pressure
below 6 Bar.
Check supply pressure.
Call for technical assis-
tance.
The nozzle doesn’t supply air
when the inflation pedal is pressed
(model with tubeless inflation).
The inflation pedal is badly ad-
justed.
Call for technical assis-
tance.
No movements take place when the
pedal is pressed.
1. Supply missed.
2. Inflation pedal unit not set cor-
rectly.
1. Check power supply.
2. Call for technical as-
sistance.
The mandrel doesn’t rotate.
1. Inverter overload alarm.
or
inverter undervoltage alarm.
or
inverter overvoltage alarm.
2. Overtemperature alarm.
1. Shorten the length of a possible
machine extension cable or in-
crease the conductors section
(disconnect and connect again).
Lift the motor pedal and wait
for the automatic reset.
2. Wait until the motor system
cools (the machine does not
restart if the temperature level
does not go below the set safety
threshold).
The mandrel doesn’t rotate, but
it attempts rotation when the ma-
chine is switched on again.
Pedalboard irreversible de-cali-
bration.
Call for technical assis-
tance.
The mandrel rotates slowly but
it does not operate on the motor
pedal.
Pedalboard reversible de-calibra-
tion.
1. Keep the pedal in rest position.
2. Keep the machine connected to
the net.
3. Wait for 30 seconds that the
pedalboard recalibration auto-
matic attempt ends.
The mandrel does not reach the
maximum rotation speed.
The mechanical resistance of the
gearmotor system has increased.
Turn the mandrel without
wheel for a few minutes so
that the system heats, thus
reducing frictions. If in the
end the mandrel does not
accelerate again, call for
assistance.
