Clamping/removing stirrer tools
WARNING
Risk of injury due to rotating parts
If necessary, stop the rotational movement (see section „Stirrer on/off
swipe field" on page 52) and before clamping/removing stirrer tools,
switch off the device to prevent it from starting up unexpectedly!
Proceed as follows to clamp/remove stirrer tools:
➜
Turn the safety ring (marked by hatching in the following figure) counterclockwise until it
stops to unlock the quick-action chuck.
➜
Pull the safety ring downward until it stops, so that you can open the quick-action chuck
(turn the quick-action chuck clockwise):
➜
Insert the stirrer tool into the quick-action chuck. Make sure that the working height is as
required!
➜
Hold the stirrer tool in the middle, where possible, and close the quick-action chuck by
turning it counterclockwise carefully until you can feel resistance.
➜
Align the stirrer tool vertically if necessary, and with the middle of the quick-action chuck
and then continue turning the quick-action chuck counterclockwise against the resistance
until three clear latching noises can be heard. In this way, the quick-action chuck is locked
and the clamped stirrer tool is fixed securely.
➜
Push and turn the safety ring back into the initial position (figure, far left), to secure and
lock the quick-action chuck.
➜
Before starting the rotational movement, check the clamped stirrer tool for tight fit and
correct true running (concentricity).
