Assembly and Mounting Instructions – You Are Ready to Start
Please perform the following steps, in order:
Step 1: Inventory the Parts List. Carefully inspect all items, making sure you have everything shown in the
Parts List.
Step 2: Seat the “pigtail” cable properly on the top of the Lift Column. Take the Lift Column (Part #1) and
find the end with the short black cable (this cable is called the “pigtail”). This end will become the TOP of the
Lift Column. Before you begin to assemble the system, you must position the pigtail properly. Look at the top
edge of the Lift Column. You will see two square cut-out channels, notched into the steel, one on either side of
the pigtail. Choose one of the cut-outs (it does not matter which one), and seat the pigtail into the cut-out,
using the rubber gasket attached to the cable.
IMPORTANT NOTE: If the pigtail cable is not properly seated, it may be damaged when you attach the monitor hanger (part #5), causing
loss of power to the lift column.
IMPORTANT NOTE:
The pigtail now hangs over one side of the Lift Column. From this point forward, that side will be referred to as the
“Front” of the Lift Column.
BEFORE (pigtail is loose) AFTER (pigtail is properly seated)
Step 3: Attach the Base Mount to the Bottom of the
Lift Column. Find the Base Mount (Part #2). Using the
small Allen wrench and four of the 6mm x 20mm Flat
Head Machine Screws, attach the Base Mount to the
bottom of the Lift Column (the end with NO pigtail).
The Base Mount has 8 holes – use the 4 innermost
holes, which will align with the 4 threaded holes in the
bottom of the Lift Column.
DO NOT OVER TIGHTEN!
