The  ball  clips  67635  are  supposed  to  move 
without play, but stilll easily. If those are difficult to 
move, press the clip on the top of the ball carefully 
with  flat  nosed  pliers  together.  Please  start  with 
less  pressure,  check  then  the  movableness  ; 
press again until you can swivel the clip easily.

Please check very carefully:

Make sure that you did not forget any part, 
especially the washers?

The Blade holders move gently and without 
friction?

Fasten temporarily 
only.
