Adjusting the tension roller
The tension roller keeps automatically the track of the sanding belt concentrically to the sanding
drum. If with time the sanding belt fails to run concentrically to the sanding drum, the tension
roller must be newly adjusted.

Adjustments of the sanding belt while the machine is running and the sanding drum cover
is open may only be performed by qualified personnel (in accordance with VBG 1,
§ 41 adjustment).
