Maintenance and cleaning
●After each use <br/>Clean the portafilter and drip tray.
● Removal and replacement of pump parts
(1) Removing the pump parts First, run water through the main body to make the pump easy to slide around.
With the lever slightly raised, use a special screwdriver to remove the screw.
Insert the prongs of the screwdriver into the screw hole and turn to remove the screw.
(2) Hold the pillar and pull it upwards to remove the entire pump part.
*Since it requires force to pull out, please be careful not to hit your arms or fingers or allow the unit to fall over.

Attach the prongs on the screwdriver and turn it while holding the post to remove the screw.
When replacing the pump, attach the new pump to the post and tighten the screws. *If the screws are loose, extraction may be affected, so make sure they are tightened before attaching the pump to the main unit.
(4) Align the joint of the mounting column with the main body and the joint of the lever, then push the pump into the main body.
