• Attach both the Shading Drive Arms with the designated screws. Ensure the counter weights are
facing down. Do not completely tighten the screws yet, some movement for installing the T-bar is
required, see figure 4.8
• Install the T-Bar (without ball rods). Install the plastic shoulder washers onto the threaded studs of
the T-Bar. Insert the shoulder washers into the side arm end holes. Install the outer flat washers
and the locking nuts ensuring that all the bushings are properly seated into the side arms. Only
loosely install the locking nuts at this stage.
• Tighten the Side Arm screws and mount the second side plate to the axis with its two screws (see
figure 4.8) after aligning the two Shading Drive Arms.
•
Now tighten the T-Bar locking nuts until most of the clearance is gone between the arms and
shoulder washers. Do not tighten snugly, ensure that the T-Bar rotates freely but has minimal
sideways movement.
•
Install the Shading Drive Arm to the T-Bar. Install the shoulder washers into the holes as shown.
Only tighten the locking nut to minimize clearances, ensure free rotational movement.
