PR.PGF714 Disassembly cleaning repair due to malfunction of cylinder

"It stopped spinning suddenly from this morning."

I have been to this apartment several times. All the cases were malfunction check repairs.

This time is also a case of malfunction repair. MIWA PR.PGF714 push-pull grip handle lock.

The apartment here does not have a space where a work vehicle can be easily parked. I had to get permission from the management office to secure the space.

I finally made it to the client's door. The apartment here is a big apartment with more than 250 units. Too wide is a problem.

The cylinder is completely stuck. It was disassembled by normal work and improved by cleaning with special oil. The rocking bar of the core cylinder was buried with considerable dirt.
