ASSEMBLY STEP 1

Fasten the Rail To the Power Unit

NOTE: To aid in assembly and installation, replace the foam packing around the power unit. Remove it after Installation Step 5.

Working on a level surface, align the rail assembly with the power unit, as shown.

Slip the coupling over the rail sprocket.

Slide the rail through the power unit bracket until the coupling fits securely over the power unit sprocket.

Align the two screw holes in the rail with those in the power unit bracket. Insert two 1/4"-20x5/8" hex screws and lock nuts. Tighten securely with a 7/16" socket wrench.

Install the Trolley

As illustrated above, slide the trolley onto and along the bottom of the rail until it snaps firmly in place. Be certain to install it facing correctly: the trolley release arm must be horizontal (lock position), with its arrow pointed away from the power unit.
