and then attach the compression piece
and the cutting rotor again.
3. Block the cutting rotor and tighten
again with the hexagon socket screw
(tightening torque 8 Nm).
4. Check the freedom of movement of
the cutting rotor and the cutting clear-
ance again (max. 0.2 mm).
If the cutting clearance is still too big,
a further adjusting washer must be re-
moved. Steps 1-4 must be repeated.
Cleaning
Worn impellers can have sharp
edges.
To clean the impeller and the spiral
housing first of all remove the com-
pression piece and the cutting rotor as
described above. Then unscrew the 4
hexagon socket screws and remove the
spiral housing.
The impeller and the spiral housing can
now be cleaned. After this fit the indi-
vidual components again and adjust the
cutting clearance.
To clean the pump chamber a flushing
pipe can be fitted as and when required.
Type I-M is screwed into place immedi-
ately in front of the flange of pump 08/2
M. With the MultiCut 20/2 M, the “Luft”
(Air) sealing screw is removed and the
Type 0 flushing pipe is screwed in.
ATTENTION! If the wrong screws are
unscrewed, the oil will run out of the oil
reservoir.

WHAT TO DO IN THE
EVENT OF ANY
PROBLEMS
Pump does not work
• Check mains current (do not use a
pin gauge)
• Fuse faulty = may be too weak (please
refer to Electrical Connection)
• Mains supply cable damaged = repair
to be carried out by manufacturer
only
Pump runs but does not pump
• Empty pressure pipe or hose to allow
the non-return valve to open and let
the air escape from the spiral hous-
ing.
Cutting system blocked
• Check the cutting system and read-
just or replace as necessary.
Impeller blocked
• Clean spiral housing and impeller.
Decreased pumping performance
• The impeller is worn out = replace it
• Wrong direction of rotation = change
