Step 7: Check whether the telescopic tube is extended to the maximum.
Secure the telescopic tube in this maximum position by tightening the
black coupling nut.
Carefully pull the mains lead out of the base. Secure the mains lead
under the heavy base by means of the four M4 nuts included in the
package. Make sure that there is no tension on the mains lead in the
tubes. Provide the mains lead with sufficient freedom to enable putting
the device in the highest position, but avoid redundant mains lead in the
tubes.
Step 8: You can now adjust the height by slightly loosening
the coupling nut and slightly pulling or lowering the top
tube. Subsequently, retighten the coupling nut at the
required height.
Step 9: Tighten the screw included in the package into the
telescopic tube, so that it no longer slides into the top part (to fix
and secure the adjustable part).
