Location of faults or breakdown
If the machine does not start, despite the above indications, or if it does not function normally, in the
following Table we indicate some possible reasons and their solutions.
It is assumed that the motor is correctly connected and that all the controls are in the correct position. If
the motor has stopped due to the intervention of a safety device, check the reason and correct the fault.
The following list describes the most frequent faults. If you note any irregularity which is not
included in those described below, stop the machine, analyze the gravity of the fault and contact
the nearest UTIFORM technical UTIFORM.
Whether the symptoms are of the more frequent type with recommended solutions
indicated, or not, prior to any operation the SAFETY INDICATIONS in this Manual must be
observed.
FAULT DIAGNOSIS
RECOMMENDED
SOLUTION
1. The indicator lights on the panel
do not light up on general contact.
1.1. Faulty bulbs.
1.2. Hot wire activated.
1.3. Battery disconnected.
