Checking the direction of motor rotation (before connecting to the
tank)
- Connect the device to the mains.
- Rotate the switch from position "0" to position "I".
- It is possible to check whether the direction of rotation of the motor corresponds to the direction
arrow indicated on the motor by briefly letting the device run.
- If they do not correspond, the polarity of the connection cable must be reversed on the device
plug (otherwise the pivoting sash propeller will become loose from the agitator shaft while using
the mixer and will be lost in the container).

Assembling the agitator shaft
The motor and agitator shaft are delivered disassembled for transport reasons.
- First of all, unscrew the pivoting sash propeller (Pos. 4) from the agitator shaft (Pos. 3.1) (Left-
hand thread!).
Key surfaces are provided on the propeller hub for unscrewing and tightening the propeller. If
the propeller is too tight, the shaft can be held down firmly on the agitator shaft coupling.
- Following this, push the agitator shaft through the opening of the motor shaft coupling (Pos.
3.3) from the coupling side of the motor until the thread of the agitator shaft is completely visible
on the connection side of the motor.
- Tighten the pivoting sash propeller (Pos. 4) again on the agitator shaft (Left-hand thread!).
- Pull the agitator shaft back to the stop.
- The mixer is now ready for connection.

The mains plug must be inserted into a socket after being checked.
NOTICE
• The mechanical seal can also be damaged by operating in the wrong direction.
• It is vital to avoid dry running the mechanical seal when the mixer is in operation.
NOTICE
• Do not hold down on the shaft firmly as this will result in the agitator shaft being damaged and
you will also damage the seal when retracting it!
