The olive harvester is not working:
- The generator is not supplying power. Generators without indicator instruments (voltmeter and ammeter) can cause damage to the olive harvester because they produce current of higher or lower voltage.
- Improper terminal connection.
- Cut or damaged cable.
- Faulty on/off switch.
- Worn or damaged carbon brushes.
- Foreign object inside the electric motor that entered through an air vent for motor cooling.
The olive harvester is operating slowly:
- Low generator voltage (below 12V) or discharged battery.
- Worn carbon brushes.
- Increased friction (non-genuine spare parts, etc.)
The electric motor is running, but the head is not moving:
- Loose or broken drive shaft.
