using the pressure of the clamping jaws
which are tightened by screws (3). The
function of the set screw (2) is to position

The blade can be fitted in three different angles.
Choose the angle according to the required stirring
power and liquid density. When in doubt, use the
middle position.
The propeller blades must be mounted in
the same position. Otherwise, the propeller
