PR.PESP.LIX(TE0)+PR.DA, Cylinder movement defect Disassembly cleaning repair

"Repair of door lock operation defect"

The movement of the cylinder seems to be stiff.Must be disassembled and cleaned.

However, I have never seen this type of push-pull door handle entrance lock.Both the main lock and the auxiliary lock have the thumbturn unlocking direction opposite to normal.In other words, it unlocks in the downward direction.

The PR.DA of the auxiliary lock is installed upside down, so you can see it from the outside, but the main lock cannot be seen at first glance.It's a rather annoying configuration.If there is a cylinder under the handle, be careful.
