Question

I have a 20-year-old Gerda door with a built-in ZW 6000 lock or some kind of progenitor of this type. I would like to fix the spring of the door handle bolt (or what is the name of the handle operated handle). I need to remove the door lock. I can unscrew the lock and loosen it, but I can not...

Hello, under the link there are no details for disassembly / assembly of the central locking with strings. In my ZW6000 I have to replace the spring of the latch wavelength, so first I have to buy it somewhere and then deal with three strands (top, bottom and back of the lock). Until now, I was able to do everything, but I did not want to risk disconnecting the lock from the strings. Where could I buy these springs and how to cleverly deal with stretches?
The service charges PLN 200, including PLN 150 for the service.

Thanks in advance for your help.

Hello
I also have the same problem with the "latch" of the door handle - the door cannot be slammed.
Is this one or more springs to replace? Because professionals write "replacement of a spring set" - but maybe they write in such a way that it sounds better

Yes, there are 2 springs in the handle's bottom plate, but they retract the handle itself, not its
bolt-lock.

I think to choose a spring from a different, ordinary lock.

I have a similar problem with making the spring, but I can't even dismantle the signboards or remove the handles in this old model Gerda star s old type and take out the inserts because from the inside the screw heads are with some unique pattern, as if with a flat screwdriver made 30% X turn and I don't know how to undo it at all ... was that something you did too? because as I can see a set of these signs, they are sold with normal screws ...

I had these too, the profile of the cut is made so that it can be tightened, but when unscrewing the tip of the screwdriver slips. I guess it was to serve as a protection against illegal startup. I don't know how to unscrew it, my screws were loose, I could unscrew it with my fingers. The bolts seem to have undergone some heat treatment, maybe they are hardened, there may be a problem with drilling. I would try gently with a punch and a hammer.

Try to tighten the wide flat screwdriver as you would, but twist to the left. For me, the service technician did so when replacing the insert. Later I did it myself, as I replaced the spring of the latch wavelet. This is a good option if the screws are not tightened too much. Even the service technician does not tighten too much because the screws are on the inside, so there is no fear that someone from the outside will unscrew it. The screws should therefore only be slightly tightened. Best regards.
