Safety 

The NTP are intended for installation in machines. 

General  applications  are:  loosening,  conveying,  compacting,  separating 
bulk  materials  and  reducing  friction.  NTP  are  used  for  emptying  bunkers 
and as drives for sieves and vibration tables. 

The NTP may also  be operated in  dusty and wet  environment, but  not in 
water or in other liquids. 

The NTP B+C may only be operated clocked. 

Any other use is considered improper. 

  

Installation,  commissioning,  maintenance and  troubleshooting  of  the  NTP 
may only be performed by authorised qualified personnel. 

All handling of the NTP is the responsibility of the operator. 

  

 IMPORTANT 

Netter

Vibration

  assumes  no  liability  for  personal  injuries  and  material 

damages if technical changes to the product were made or the notices and 
regulations in these instructions were not observed. 

  

 WARNING 

 

Falling parts 

The NTP, construction parts as well as fastening screws can 
come  loose  due  to  vibration.  Falling  parts  lead  to  severe 
personal injuries. 

  Check  the  fastening  screws  after  one  hour  of  operation 

and thereafter at regular intervals (generally monthly). 

  Retighten the fastening screws, if necessary. 

  A safety device with a safety cable is mandatory for criti-

cal mounting situations. 

  

 WARNING 

Compressed air 

A loosened hose which is under pressure can lead to personal injuries. 

  Screw the hose lines on carefully. 

  Check the hose lines and connections after one hour of operation and 

thereafter regularly (generally monthly). 

  Retighten the hose lines, if necessary. 

  Ensure  that  the  compressed  air  is  disconnected  from  the  supply  lines 

during all work on the NTP. 

  Prevent the NTP from being switched back on during all work.
