ASSEMBLY STEP 2

Install the Trolley

•As a temporary stop, insert a screwdriver into the hole in the front end of the rail.

•Slide the trolley assembly along the rail to the screwdriver stop. NOTE: If trolley hits against any nuts on the rail, the bolts and nuts were attached from the wrong side and must be repositioned. Review Assembly Step 1.

•Insert a 5/16"-18x7/8" hex bolt into the trolley stop hole in the rail as shown. Tighten securely with a 5/16" lock washer and nut. This bolt limits trolley travel in the DOWN direction.

•Align the holes in the back section of the rail with the holes in the motor unit.

•Fasten the rail with the two washered bolts previously removed. Tighten securely.

Remember to use only these bolts! Any other bolts will cause serious damage to the opener.

•Insert a 5/16"-18x7/8" hex bolt into the cover protection bolt hole in the rail as shown. Tighten securely with a 5/16" lock washer and nut.
