4. Description of the product
Warning
Risk of injury!
The end product may present further, previously
unforeseeable hazards.
Warning
Risk of injury!
Despite a number of software based protective
guards there is still a
risk of getting crushed in exceptional cases as
motor shutdown is not only governed by the
control unit but also by the interaction of the
mechanical and electronic components!
Shutdown sensitivity is also influenced by the
mechanical components, motor and ambient
conditions!
For this reason, the manufacturer cannot entirely
rule out this residual risk and does not accept
any liability!

5.2.1 Installing lifting column
Fit the lifting column to the skid and desk top support. To do this
you will need the following tools:
· 1 x hex driver,
· 8 x M6 hexagon socket head screws per lifting column.
To install the lifting column proceed as follows:
1. Connect a skid to a lifting column by means of four hexagon
socket head screws.
Fig. 15. Attaching lifting column (viewed from below) to
example skid
2. Now tighten the four screws on each lifting column to
7 Nm max. using a hex driver.
3. Now connect the requisite lifting columns to the desk top
support by means of four hexagon socket head screws per
lifting column.
iNote
Use M6 screws of appropriate length, paying
attention to maximum screw length. The screw
must be driven into the column by 8 - 12 mm.
iNote
An even standing surface with a sucient load
bearing capacity is essential for setting up the
height adjustable desk in a proper and safe
manner. Any unevenness in the standing surface
must be evened out.
iNote
If lifting columns are replaced in a system, it is
imperative to return the lifting columns to facto-
ry settings first (see Section 7.5.9) and perform a
manual reset (see Section 7.4.4).
