Troubleshooting
The following chapter describes the possible
causes of faults and the procedures to repair them.

maintenance intervals in line with the actual
load on the system.

WARNING Danger of injury due to moving
parts
Rotating components and/or components with
linear motions can cause serious injury.
►
Prior to all troubleshooting work on moving
parts switch the machine off and safeguard it
against being switched back on. Wait until all
parts have come to a standstill.
►
When in the hazardous area wear closely fitting
clothes with a minimal tear strength.
WARNING Risk of death due to
unauthorised switching on
An unauthorised switching on of the power supply
during fault-finding and troubleshooting results in
the risk of severe injuries and even death to
persons in the hazardous area.
►
Prior to work starting switch off all power
supplies and safeguard against a restart.
WARNING Risk of injury due to
unprofessional troubleshooting
The unprofessional execution of troubleshooting
work can lead to severe injuries and considerable
damage to property.
►
Prior to starting work ensure that there is
adequate free space for installation.
►
Ensure order and cleanliness at the installation
site. Loosely stacked or scattered parts and
tools can cause accidents.

If parts have been removed, ensure that these
are assembled correctly, reattach all fixing
elements and adhere to the specified thread
tightening torques.

Prior to a restart, ensure the following:
•
Ensure that all troubleshooting work is
carried out and completed in accordance
with the specifications and instructions in
this manual.

Ensure that no one is present in the
hazardous area.

Ensure that all covers and safety devices
are installed and that these function
correctly.

surfaces
During operation, individual parts of the carrier or
transverse drum cutter can become very hot and
cause burns.

Before commencing with troubleshooting, allow
hot parts to cool to the ambient temperature.
►
Wear heat-resistant gloves.
