ERS-31x Potentiometer cleaning guide (ERS-311, 312, 31L)

Put the neck mechanism on its side. You will notice a single potentiometer mounted 
on the side. This is a similar type to the ones found on the Hip/Shoulder mechanism 
and  therefore  has  slots  in  which  switch  cleaner  can  be  sprayed  into.  Once  the 
cleaner  has  been  sprayed  into  the  potentiometer,  carefully  move the head up and 
down in order to work the neck joint. 
 
It  is  possible  to  remove  the  potentiometer  from  the  mechanism  by  carefully  prying 
open the two clips (1 and 2) and lifting it out of the housing. It can then be cleaned in 
the  same  way  as  the  Hip/Shoulder  potentiometers  (5.07  to  5.11).  It  may  be 
necessary to unclip the wiring loom from the plastic retaining clips to allow enough 
movement for the potentiometer to be removed. Please note that the potentiometer is 
mounted on a flexi and is therefore very fragile. 
 
Reassembly is a reversal of instructions 6.01 to 6.03
