Important Guidelines
Adjusting the blending power
The blending power is determined by the distance between the paddles and the door. The smaller the gap, the
more powerful the blending.
The initial paddle setting is factory set for a standard use with a standard power. When the unit is empty, without
a bag, the paddles just touch the door. From this position, you can move the paddles 3 mm forward or retract
them by 15 mm, depending on your requirements.
Depending on the nature of the sample, you may need to increase or reduce the blending power, i.e. advance or
retract the paddles. To do this, simply turn the handle at the rear of the unit counter-clockwise to advance the
paddles or clockwise to retract them. For information, one complete revolution corresponds to a displacement of
1.5 mm.
To revert to the factory setting (“standard setting”), please follow the instructions at the back of the unit.
