of motion
Re-synchronize Table
Refer to synchronization procedure.
(see Common Procedures)
Faulty Lifting Column
Test Lifting Columns individually (see Common Procedures),
and replace any faulty Lifting Columns. Be sure to test all Lifting
Columns! Why? Because another Lifting Column may have the same
problem at a different height.
Lifting Columns not

Lifting Columns are not
parallel with one another,
causing them to bind
First ensure that glides are properly adjusted, and the Table is level.
Loosen (but do not remove) all of the screws attaching the Lifting
Columns to the worksurface.
For Series 7 Tables, ensure Stretcher is fully-seated in the backs of
the Lifting Columns.
Operate the Table through a complete up-down cycle and then
re-tighten worksurface attachment screws.
Still binding? Take everything off the Table, flip it upside down, and
remove the worksurface screws completely. Run the Table through
another up-down cycle. The position of the Lifting Columns may shift
slightly; re-install worksurface screws in the adjusted position.
