Hi Tb123.
Firstly don't throw your bowl against the wall.
It takes a little time to get use to assembling your TM bowl.
Pop the blades into the bottom of your bowl.They can only go in one way.
Now sit the jug onto the bottom bit .The handle will be to the right.Make sure the blades are still sitting in the bottom.
Now push the bottom piece to the right and the handle to the left.You might have to hold the blades as you do this.
Being a new jug it maybe stiff.
If you get together,keep taking it apart and assembling it until becomes second nature.
