Symbols 

 
The following symbols draw attention to the different danger levels in the individual chapters: 
 

Please follow the work and procedures marked with this pictogram exactly. Failure to do so may result   
in damage to the machine or the cable. 

 

This pictogram refers to working and operating procedures that must be followed, as well as important 
information on the functioning of the system. 

 

Product description

 

 
In this document the designation ST215 refers to all machine types 

ST215

 / 

ST215W

 and 

Polystrip

 
The  ST215  is  a  high-precision  stripping  and  twisting  machine  especially  designed  for  stripping  small 
diameter  cables.  The  high  processing  quality  paired  with  high-quality  materials  make  the  ST215  a  robust 
production machine.  
The  ST215  is  a  real  all-rounder;  it  masters  stripping  of  standard  cables  in  short  cycle  times  as  well  as 
micro-coaxial cables with highest precision. The absence of grippers allows the ST215 to process shortest 
cable ends, crushes on the outer jacket are excluded. The patented 4 blade system enables an absolutely 
precise and repeatable stripping of cable ends.  
The jacket is removed by a rotary incision with subsequent pulling-off in a single operation. The ST215 can 
be infinitely adjusted to another diameter or length in seconds using a scale. 
 
 System overview: 
 

  Rotary incision 

  Stripping head with a 4 blade system in one plane 

  Knife changing performed without tools 

  Stepless adjustment of diameter and length via a scale   

 

The  ST215  is  suitable  exclusively  for  stripping  copper  conductors.  Make  sure  that  no 
metallic objects (e.g. screwdrivers, tweezers) come into the vicinity of the blades, otherwise 
the blades will be damaged. 

 
Centering unit (ST215 and ST215W) 

 
The  infinitely  adjustable  centering  unit  ensures  that  the  cable  is  precisely  aligned  with  the  center  of  the 
blades. If your ST215 was delivered without centering device, you can easily retrofit it. 
 
The advantages of the centering unit are as follows: 
 

  Influencing of the stripping quality by the user is practically ruled out. 

  The stripping diameter can be set very close to the conductor, enabling very thin walled insulations to 

be stripped without problem.
