3.3 Maintenance
Clean the suction ducts regularly. The dust bag is emptied after use. Replace the grinding
surface on the level grinding table as needed.
For belt replacements, the pressure is taken off the belt by turning the handle (D) on fig.
2.2.5 counterclockwise. The housing (see fig. 2.2.4) is disassembled and the worn belt is
removed. Put a new belt on and verify that the direction of the arrows on the back of the
belt, are equivalent to the direction of the rotation. The handle (D) is turned back clockwise
until the belt is tightened. And then the housing is assembled again.
Check that the belt runs in the middle by turning the belt around with your hand and adjust
inwards if necessary.
3.4 Roll holder
– location of contact discs
The distance between belt grinder and contact weel must be changed when you wish to
grind another pipe dimension.
As an illustrative indication, we have made a drawing of t
he roll holder’s 11 possible
positions, corresponding to different roll sizes.

On the side of the aggregate you will find a sticker with the above table.
