6 Operation and settings
6.1 Safety
The Activa Lift 2 desk should only be used and operated in faultless condition and in compliance
with the instructions in the user manual.
Prerequisites for adjusting the height of the desk:
• Persons or objects should not be in the entire lift range e.g. open doors or windows, nor should
objects protrude into the lift range.
• There should be no objects in the lift range of the lift column.
• No one should be on the desk.
• The maximum permissible load capacity of the desk should not be exceeded (see sticker) (See
3.1 Technical data on page 7).
• There should be no heavy loads on the desktop (e.g. devices or large amounts of paper). Heavy
loads make the height adjustment more difficult.
• The desktop must be horizontal. If the floor is uneven, align the desktop via the adjustment
screws on the feet (See 5.4 Height compensation on page 15).
