Einleitung

The zoom wheel controls the position of the blade guard, which then determines how much hair will be removed when trimming.

Werkzeuge

Schritt 1

Press the black button below the blade to remove the blade.

Schritt 2

Place the device so the back of the product is facing up.
Remove the two 11.0 mm PH00 screws from the black plastic housing at the bottom of the device.

What do you do if the screws strip? they are really cheap

Where does one get the actual battery replacement from?

You must use a very small blade Phillips screwdriver. A #0 will be too big. Significant downward pressure is also needed to break the screw loose and prevent stripping the screw. It feels like they are glued in. The battery is available in many places and is a 14500 type rated at 750mAh with a 4mm tab on the positive side and a 2.5mm tab on the negative side.

Schritt 3

Remove the chrome plated plastic piece by using the plastic opening tool to pry it from the housing assembly.
Remove the small clear plastic piece that covers the zoom wheel numbers.

there is double face tape at each end of the chromed plastic piece along with the tabs that need to be unhooked when prying off. So be tender and do not use brute force. Also, the clear plastic piece will likely just fall out so be aware.

Schritt 4

Remove the two 16.0 mm PH00 screws from the front cover.
Use the blue plastic opening tool to pry apart the two halves of the device.

If you happen to lose the two springs, you can cut off 2x10mm of a spring from a pen :P

Merry trimming and a happy new beard !

I bought a set of Draper screwdrivers specifically for this. Can’t shift any of the screws. Ideas?

The screws holding the body together seem to be of poor quality and possible glued in place, I only managed to remove one with quite a high quality screwdriver and had to drill out the others. Taking this apart takes longer than 15 mins on it’s own leave alone doing repairs.

On a MB4045 model, I can confirm that the screws are glued into the plastic and cannot be unscrewed. I had to Dremel out the heads and dremeled a fair bit of plastic in the process. These trimmer model are designed for planned obsolescence. Shameful. The whole disassembly took me 1hr +

Schritt 5

Remove the black blade button and the two 10.0 mm springs, which are sandwiched between the cover assembly halves.
The blade button is sandwiched between the halves and the two springs may fall out when the halves are separated.

Schritt 6

Remove the two 11.0 mm PH00 screws that attach the zoom wheel to the plastic housing.

Schritt 7

Remove zoom wheel assembly from housing using fingers.
Gently remove zoom wheel assembly because the red and black wires are attached and can easily be broken.
This assembly also houses the motor.
Remove the small black piece of plastic surrounding the zoom wheel. This will be referred to as the slider.
When reassembling, make sure the pins on the slider are aligned inside the grooves of the wheel.
