With the comfort sieve clamping unit
KM
 Screw the mounting rods into the sieve disk
 Center the selected sieve stack on the sieve disk
 Slide the comfort clamping cover over the mounting rods,
whereby pressing the red lever upwards allows the clamping
cover to move. The green levers remain in their initial posi-
tion.
 Slide the clamping cover down to the top sieve
 Press the green lever downward several times, whereby the
red lever may not be moved.

To release, use the thumb to press only the red lever upward,
the sieve cover can now be slid upward.
If, after the sieving process, the red lever proves difficult to
move, press the green lever and the red lever simultaneously for
a short time to release the tension.
We recommend the use of talcum powder if the base pan sticks
to the smooth surface of the sieve carrier when removing the
sieve stack.
When using the comfort sieve clamping unit, we recommend
that the mounting rods are cleaning from time to time. In addi-
tion, the comfort sieve clamping unit produces unavoidable
clamping notches on the mounting rods after a certain period of
time, which can hinder secure clamping.
It is therefore necessary to examine the mounting rods at regu-
lar intervals for notches in the clamping area, and then turn
them through 90°, if required. Use a 17mm open-ended spanner
for this purpose.
Turning the mounting rods:

Release lock nut KM.

Turn the mounting rods through 90°.

Retighten the lock nut securely.
If turning the mounting rods through 90° does not produce any
notch free areas, we recommend that the mounting rods be re-
placed.
