7. Troubleshooting
In order to prevent damage or serious injury while rec-
tifying machine faults, the following points must be ob-
served:
•
Only attempt to rectify a fault if you have qualified
personnel. This means each job must be carried out
by trained specialist personnel, for example electrical
work must be performed by a trained electrician.
•
Always secure the machine against an accidental
restart by disconnecting it from the electric system.
Take appropriate safety precautions.
•
Independent work on the machine is at one‘s own
risk and releases the manufacturer from any warranty
obligation.

A malfunction of the lifting station is reported via the built-
in alarm beeper. If the alarm does not shut off after one
minute automatically, please disconnect the power plug
for one minute to draw the electronics to reset. If the
alarm starts again - after power cable is plugged in - please
contact your customer service.
6. Maintenance
6.1. General
The entire system must be inspected and maintained at
regular intervals.
The following points must be noted:
The operating instructions must be available to the main-
tenance personnel and must be followed.
•
Only maintenance work and measures listed here
must be carried out.
•
All maintenance work, inspection work and cleaning
work on the machinery and the system must be car-
ried out with due diligence, at a safe working place
and by trained qualified personnel. The required pro-
tective gear must be worn. The machinery must be
disconnected from the power supply for all work. Un-
intentional start must be prevented.
•
Electric works on the machinery and the system
must be carried out by a specialist.
•
If easily inflammable dissolvers and cleaning mate-
rials are used, open fire, open light and smoking are
prohibited.
•
Ensure that the required tools and materials are read-
ily available. Tidiness and cleanness ensure safe and
proper work on the machinery. Remove used clean-
ing materials and tools from the machinery after the
work has been carried out. Keep all materials and
tools in a dedicated place.
A test run or function test of the machinery must only
be carried out according to the general operating con-
ditions!
6.2. Maintenance schedule
Every six months:
•
Visual inspection of the power supply leads

The power inlet leads must be inspected for bubbles,
cracks, scratches, scour marks and/or crushing zones.
If damages are detected, the damaged power inlet lead

or an authorised/certified service workshop. The ma-
chinery must only be started after appropriate repair
of the damage!
