DC20 Lifting Column Installation
92299 1.0 21
Installation: Head and foot of the DC20 lifting column

Use M8x40 threaded cap screws (strength class 8.8) (as shown in Figure 8) for mounting the
DC20 lifting column. The tightening torque should be between 15 and 17 Nm.
 The screws must not be loosened and re-tightened more than 2 times (only in the same thread!)
to prevent damage and weakening of the screw connection.
