Default Braun shaver- how does it come apart? Battery type?

DaveC writes:

Braun 5 476 shaver. How is it held together? Can't find any screws or obvious
clips that keep it in one piece.

On the back there is an international "recycle" symbol with the term "NH
accu". What type of batteries are these? Sources?


Frequently there's two plastic plugs besides the connector. Carefully
pry them out and there will likely be a phillips head screw there.

The batteries are normally NiMh. The Brauns I've replaced the
batteries in has had one or two AA cells.


Thanks,

Where did you buy the batteries?

Default Braun shaver- how does it come apart? Battery type?

Hi Dave,
I read with interest your informative note about batteries to Thomas .
My somewhat elderly although working Braun shaver does not hold a charge for
very long nowadays. I presume this is because the battery is failing ( I had
a look and its a HR-AA BKH). cannot see how to get it out easily or if its
soldered in or not. Any ideas? Are the batteries still available? I presume
if the charging circuit is knackered there isn't much point any more.
Regards
Roy

Here's the service manual.
http://63.230.9.155/braun/Srv_Man/SHAVER/
scroll down to the PDF for the 5476. It appears to have some similarities
to my 4501-it appears to use one NiMH AA cell with solder tabs, and it
employs a self-destruct device for the casing when the shaver is being
thrown away (a one-way coin turning device around the power jack; see
manual). I was able to defeat this device and reassemble
my shaver. I bought a NiMH cell with solder tabs from Thomas Distributing,
http://thomas-distributing.com/
but most solderable cells come with sheet metal tabs instead of wires, so
I had to cut them down.

Hi,

Here's the service manual.
http://63.230.9.155/braun/Srv_Man/SHAVER/


Thanks a lot. What a co-incidence! I dropped my brown shaver a few
months ago and it immediately stopped to do anything. After a short
unsuccessful attempt to open it, I gave up and used my old Gilette.

Today, I finally decided to do a google search to find any information
on how to open it before I have to buy new razor blades. And almost
the first link it gives me is this thread and the link to the service
manuals. That's far more than I expected!!!

Thanks for pointing this out. My 6510 (manual 5705) seems to have the
same. I didn't expect anything that nasty in there. I would have
probably turned the big coin screw as soon as I found it. I will try
to stay clear of it. The batteries are still fine anyway.

Now I only have to find the shaver again and I will try to see what's
broken tonight. I hope, it's just a cable which came off somewhere.

As I recall, the self-destruct device opens the case but bends some
plastic tabs. I recall being able to bend them back to restore the
self-destruct assembly to be able to reassemble the case. I do not know if
the case can even be opened without at least partially activating the
self-destruct device! And of course, 2 screws are hidden behind plugs.

Hi,

As I recall, the self-destruct device opens the case but bends some
plastic tabs. I recall being able to bend them back to restore the
self-destruct assembly to be able to reassemble the case. I do not know if
the case can even be opened without at least partially activating the
self-destruct device! And of course, 2 screws are hidden behind plugs.


When I looked at it last night, it seems that I must have tried the
coin opening method (it was scratched), but luckily not hard enough.
The two screws behind the plastic plugs work perfectly well. I just
didn't find them the first time round. The case slight open easily
when those two screws are opened.

And the service manual was very helpful. It gives very detailed
instructions on how to take it apart step by step and what to look out
for when reasempling. The shaver is actually designed to be
servicable, which I find quite impressive for a consumer product in
this price range.

In the end, it was actually something which I didn't expect. The motor
has a little notch on the axle, which turns round and moves the knife
part up and down. My shaver has a head which can swing and the axle
pin (they call it eccenter) is in a groove. When the shaver fell down,
it must have jumped out and the motor wasn't able to turn any more.
All the electronics was still fine. It took mine almost completely
apart before I realised this was the cause, but it would have been
enough to just take the head of and put it on again. They even mention
this as a potential problem in the service manual.

Anyway, it's working now.

Thanks again to G. Louie for the link,

Christoph

Default Braun shaver- how does it come apart? Battery type?

Hi again.

Sorry for not replying earlier.

This series of Braun shavers had the option of a standard (slow) oscillating
speed, or for $$ or ££ you could buy the model with a faster oscillating
speed.


I have a 6510, which is very similar to the 6520 (one LED is missing).
It is one of the "Ultraspeed series" with "Oscillating head with
triple shaving system", i.e. two normal shavers next to each other
with a long-hair type one inbetween, which is supposed to take out
whatever the other two don't catch. It seems to work to a certain
extend. It still has a separate long-hair trimmer.

Anyone know the difference? I presume the motor is simply a dc motor and that
the faster speed is the result of a higher-rpm motor in that model.


In the service manual 5705 I got it says:

Drive: 2.4 V d.c. motor.

Number of revolutions with operating battery
after a minimum of 3 minutes charging time:

only cutter block min. 6900 rev./min.
max. 8500 rev./min.
with long hair trimmer min. 6600 rev./min.

I had the idea to somehow speed up my shaver, but I see that this might not
be practical.


Maybe you could check out

http://63.230.9.155/braun/Srv_Man/SHAVER/

and have a look at shvcross.pdf to see whether your model is listed as
well.

I hope this helps,

Christoph

Anyone know where this site went? I have been unable to bring it up.


The wayback machine still has some of it.
