7 Maintenance
This unit should only be installed and maintained by qualified specialist personnel
(mechanics and electricians). Work on electrical equipment may only be carried
out by qualified electricians.
The vacuum pump and linear actuator may not be opened during the
warranty period. If opened, this invalidates the warranty.
Use cold cleaner (not benzine or corrosive liquids. This causes leaks or irreparable
damage to the vacuum hoses) to clean the device.
After repair and maintenance work, always check safety equipment as set out in
chapter on "Safety".
Some components on the lifting device are still live after the device switch is
pressed!
When working on electrical components of the lifting device, it must be
disconnected completely from the power supply using the upstream disconnector
or maintenance switch!
