Belt drive
The correct belt tension is of utmost importance in order to obtain a perfect power transmission and to reach
the usual working life of the belt. Too low or to high tension can cause a premature breakdown of the belt.
Excessive belt tension results in damaged bearings.
If you change the height of the motor plate, the tension of the belt can be adjusted.
Unscrew the counter nut (2) and turn the adjusting nut (3) to change the height of the motor plate and thus
the belt tension. Check the tension by pressing on the belt, it has the correct tension if you can press it in for
approximately 8 mm (between 70 and 75Hz). Fix the setting with the counter nut.
Always check the belt tension after mounting a drum.
