FAQ

Increased vibration and noise are usually warning signs that the machine needs mechanical maintenance. Common causes include:

• Uneven dust build‑up on the fan impeller – this throws off the dynamic balance.

• Bearings running dry or worn out – lack of lubrication causes progressive wear.

• Loose bolts and fasteners – thermal expansion/contraction can loosen them over time.

If you notice these signs, stop the machine immediately and have a professional technician inspect and service it.

This is a classic mechanical jam – cut the power immediately! Possible causes:

• Belt too loose or broken – adjust tension so that the belt deflects about 10‑15 mm at the midpoint.

• Bearings seized due to dryness – apply food‑grade high‑temperature grease.

• Foreign object stuck inside the drum – stop and inspect.

Do not keep trying to restart – repeated attempts may burn out the motor. It’s safest to contact after‑sales support for professional handling.
