Braun 4169 disassembly procedure
4169 blender dismantling.
this device is not suitable to be dismantled but this is how I did it.
1 disconnect from the mains.
2 lever off operating lever button at opposite end to hinge
3 insert sharp screwdriver into gap by top lid at same side as cable entry and prise off
4 heat up the casing with an electric paint stripper, wear gardening gloves.
5 when the casing starts to get pliable, insert a driver into the gap above the operating button locating lip and prise away as far as you can
6 do this with the locating peg on the other side
7 work between the two until the whole thing comes apart
8 lever out the motor, it will slide out once loosened
9 wash out the blender drive shaft with boiling water and detergent
10 dry out the body and soak the inside with silicone oil
11 work the blender blade until it spins freely
12 clean everything up and push it all back together
13 if any parts are deformed with the heat gun reheat them to a pliable state and reform them as best you can
14 if it is all loose when its back together, glue the joints with superglue and spray with glue accelerator
15 test it and if it's no good chuck it in the bin and buy a new one
16 but mine works fine.
