1. Slightly loosen the tie rod screws (1) so that any residual pressure
can escape completely.
2. Then loosen the tie rod screws (1) completely.
3. Remove and clean the pressure flange (2) with mortar pressure
gauge.
4. Remove the pump unit (3) and push the rotor (4) out of the stator
(5) and clean it.
5. Completely reassemble the pump unit (3).
6. Mount the pressure flange (2) and tighten the tie rod screws (1)
again.
NOTE
It is essential to spray the pump (rotor in stator) with
assembly spray before assembly, as otherwise the break-
away torque required for the pump motor is too high.
