[Solved] Broken locking mechanism in Zelmer Cobra II Silent telescopic tube

I have had a problem with locking the mechanism in the telescope for some time. It takes a lot of effort to block it and prevent the pipe from folding itself. That's why I keep my vacuum cleaner with the pipe stretched all the time ... is there any advice?

There seems to be no help for this. It would be hard to take it all apart, and even harder to put it together so that the pawl, spring and plates were in place and everything worked. Even Zelmer's warranty does not cover the pipe, so the only solution is to replace it with a new one. They also say that it is not difficult for a wanting person, but is it profitable? :P

Thanks for the reply However, I will probably stay with the constantly unfolded pipe, because replacing it with a new one at a price of PLN 40 (I gave PLN 250 for a vacuum cleaner) is not an option.

i had the same problem i just found a solution!

Move the lock to the max following the arrows. A small hole will appear. Squeeze hand cream in there and activate the mechanism. For me, after 5 minutes of starting the mechanism, it stopped jamming and the lock works again as it should!

Pipe to be replaced, it is made in such a way that it should break, it cannot be repaired. Once you take it apart, you won't put it back together.

I edited my post, I found a cheaper solution than replacing the pipe above.

Short-term solution, after several uses the problem will return.

I put the cream here, the question of durability - we will see it now works, the mechanism has started to work louder (you can hear that it is blocking correctly). For me, it is better than a new pipe, since there is no possibility of disassembling and repairing it. The matter of choosing the right consistency of the lubricant

I have the same pipe, I got killed but dismantled and repaired it, it took me 3 hours, but without basic knowledge and good memory of where to go, I can't take it.

I will share my observations.

Once the tube locking mechanism in my vacuum cleaner stopped blocking, I started looking for a fix on the net. Reading this thread terrified me. (among others - expenses for a new pipe). Losing nothing, I started the demolition.
The mechanism consists of 6 parts, counting with a screw, it is very simple and it is difficult to assemble something wrong. The repair, including gluing the damaged plastic sleeve, took 15 minutes.
If the mechanism cannot be repaired, it is always very easy to block the pipe permanently.
I don't know why people say very often that "it's impossible to fix" or that repair is very time-consuming. Then it turns out that more time a person will spend looking for a solution on the Internet than it takes to repair the damaged part.

The repair is very simple. It took me 10 minutes. The mechanism is very simple and it is not difficult to reassemble it. It should not be forcibly disassembled only by means of a method. Everything works like new.

It's nice that it's easy. You could also describe how to do it one by one. That would be the solution to the problem.

Of course
-First, you need to remove the slide (the plastic that is on the outside) - e.g. pry from the side with a screwdriver.
- after removing the plastic, the screw appears. After unscrewing it, you can slide out the entire mechanism.
When we have everything on top, we can start repairing it.
Its method depends on the damage to the mechanism (in my case, it was necessary to glue the cracked plastic together).
We fold in the reverse order.

I guess that was it

Hey
The key to everything is prying that plastic off the side. I add photos so that everyone knows what's going on because taking it apart is trivial.
You have to pry on the side in the photos you can see where the plastic has a latch. When undressing, be careful not to lose the metal roller responsible for blocking.

Overall, maybe it is - just like the structure of this mechanism.
Unfortunately - in the case of my pipe, removing the slider (even though I knew exactly how and where it was attached) was almost a miracle - by the way, the catch in this light gray cube with a spring broke. Luckily, it's not serious.
Worse, that (as it turned out later) the thin stop on the right side of the metal roller (looking at the third photo) was also crushed, so the repair may not be effective.
Maintaining the pressure force on such a poor crossbar, which arises, for example, when vacuuming a carpet, sooner or later (rather sooner) will cause it to crumble.
