Total damage due to moisture penetration
Moisture ingress in the connection cable damages the connection cable and the mixer!
Never immerse the end of the connection cable in a fluid and firmly seal it during storage.
ƒ

ƒ
Secure the mixer against falling over and slipping!
ƒ
Do not set the mixer down on the propeller. In the case of larger propeller diameters, en-
sure an appropriate platform is provided.
CAUTION! Material damage! Propeller and shaft can be damaged!
ƒ
Store the mixer for a maximum of one year. Contact customer service before storing the
device for more than one year.
