Replacing the impeller unit
N O T E
The impeller unit is guided in the motor block by a bearing. This bearing is a wear part and should be changed
at the same time as the impeller unit.
• Changing the bearing requires specialist knowledge and tools. Have the bearing changed by your OASE
specialist dealer or send the pump to OASE.
N O T E
The impeller unit contains strong magnets that attract magnetic particles (e.g. iron filings).
• All particles must be removed from the impeller unit before reassembly. Any remaining particles can cause
irreparable damage to the impeller unit and motor block.
How to proceed:

– The filter basket is fastened to the pump with a bayonet lock.
2. Push back the locking button under the stand and pull the pump off the stand.
3. Remove the four screws and take off the pump casing.
4. Pull out the impeller unit and replace if necessary.
– Use a wide-blade screwdriver to carefully lever out the impeller unit if necessary.
5. Reassemble the unit in the reverse order.
