  Check and lubricate articulated arms, articulated

  screws, tension springs and tensioning chains.

  Adjust articulated arms if required.

  Funnel discharge:

  Lubricate sealing washer between the discharge

  casing and geared motor and the universal joint of

  the screw conveyor.

  instructions for the hydraulic unit.

WARNING

Risk of serious or fatal injury through becoming trapped or 

crushed by moving parts. Before starting any maintenance 

work on the conveyor devices, switch OFF the heating 

system at the mains isolator. Safeguard the system 

against reconnection.

WARNING

Risk of being crushed, cut or entangled by rotating or 

moving parts as a result of missing protective covers.

After completing maintenance work on the conveyor

devices, ensure that all protective covers are re-installed
