8.6 Recommendation for dry or wet trimming
• Dry trimming is not allowed when the MTplus is equipped for wet trimming�

• Not observing the prior instructions will result in plaster residue mixing with water and hardening to a
difficult to remove crust. Such residues particularly on the back of the trimmer disc can lead to imbal-
ance�
8.7 Grinding Angle Adjustment (89° - 99°)
1� Loosen the knurled nut (Fig� 17)�
2a� Adjust the grinding angle roughly with the adjusting screw (Fig� 18)�
If the adjusting screw is turned to the top, the angle between model table and trimmer disc is of 89°�
If the adjusting screw is completely turned out, the angle between model table and trimmer disc is
of 99°�
2b� Adjustment of the model table roughly with the adjusting screw (Fig� 18)� The lower border of the
model table should coincide with the upper border of the model-table support (Fig. 19 + 20).
2c� Fine adjustment of the model table at 90° with the adjusting screw (Fig� 18) and set square out of the

8.8 Operation / Trimming
Using both hands, securely set the model on the trimmer table and press it against the disc (Fig� 22)�
9 Cleaning / Maintenance
A raising of plaster dust in aerodynamic dead areas when dry trimming is normal and has no neg-
ative influence on the function or grinding power of the MTplus.

1� Disconnect the unit from the power supply (Fig� 7 or 14)�
2� If necessary, shut off the water supply (Fig� 6)�

damaged!
4b� For dry trimmer: Clean using a vacuum and brush (Fig� 26)� Clean the drain tube and tube connec-
tion (Fig� 27)�
