MACHINE STOPS WORKING
If your Lavina 21 suddenly stops working, push the Emergency Stop Button and check if the power arrives to the
machine. If the power arrives to the machine it could be that the overload
Relay is tripped. The motor has manual reset overload protection. Wait until the device is cooled down (up to one hour)
and push the button down under the cable box of the motor (Fig.9.B.8.1, Fig.9.B.8.2) to reset the relay.

The tripping of the overload relay could have 2 reasons: either the operator has overloaded the motor of the machine or
the cable from the outlet is longer than 20 m or 65 feet
