Installing the Central Axis

Tube
Figure 5: Installing the Central Axis on a
110mm Down Tube
Installing the Central Axis requires two people and
using an equipment lift is HIGHLY recommended.
See Section 3 for the Mounting Plate and Ceiling
Structure guidelines.
Once the support structure and Hex Plate/Down Tube
are securely installed and level, the Central Axis is
ready to be installed. Locate the Securing Segment,
Flat Head Screw and Allen Cap Screw and have ready.
NOTE: The DC Power Cables and Ground Cable
(not shown) coming out of the Central Axis must be
guided up through the Down Tube while lifting the
hub of the Central Axis up into the Down Tube.
Using an equipment lift position the Central Axis under
the bottom of the Down Tube. Carefully position the
Central Axis so that the hub aligns with the Down Tube.
Lift the Central Axis until the hub goes up into the Down
Tube until it lines up with the Securing Segment slot.
Insert a greased Securing Segment until it stops and
ensure that it is seated. The outer edge of the Securing
Segment must be inside the outer diameter of the
Down Tube.
With the Securing Segment installed, insert the Flat
Head Screw into the top hole and then install the Allen
Cap into the lower hole. Slowly remove height from the
equipment lift and check the rotations. If the Central
Axis rotates smoothly and without binding, tighten the
Allen Cap and then tighten the Flat Head Screw.
Recheck the ease of rotation.
The tightness of the Flat Head Screw and the Allen
Cap should be incorporated into the equipment

Mounting with the 110mm Down Tube
Using an equipment lift position the Central Axis under
the bottom of the Down Tube. Carefully position the
Central Axis so that the hub aligns with the Down Tube.
Lift the Central Axis until the hub goes up into the Down
Tube. Continue lifting until the screw holes in the Down
Tube aligns with the thread holes. Insert the 8 socket
cap screws ensuring that the screws are seated and
sufficiently tight.
Rotate the Extension Arm(s) to ensure free and smooth
rotation.
