Step 10: Counterweight Installation:

Diagram 10a

• Remove the Counterweight bar and the box containing the 8 – 2 1/2lb weights from the shipping box.

• Remove the nuts and washers from the side of the counter weight bar opposite of the jamb nut and slide all

of the 2 1/2lb weights onto the bar and over the rubber sleeve.

• Re-thread the nuts and washers that were removed in the previous step, back onto the counterweight bar.

• Thread the counterweight bar into the welded nut on the lower side of the bottom rail according to Diagram

10b and tighten the jamb nut against the welded nut. We will worry about balancing the tracker later.
