Take a magnet that you want to separate from the stack and place it on the withdrawal plate, adjust for its height and fasten the screw. (If the magnets are separated by a distance piece, adjust for the height of the magnet plus the distance piece.) Place the separator with the rubber footing down on an even surface.
Alternative: Remove the rubber footing and screw the separator to an even surface with a screw clamp.
Place the magnet stack into the device and set it for enough clearance. Now use the lever to separate the magnets.
Now you can conveniently remove the magnet from the withdrawal plate. The magnet separator is made of aluminium, so the magnets don't adhere to it.
Make sure you place the separated magnets far enough away from each other, otherwise they attract each other anew and you have to start over!
