[. . . ] Hand chain length is twice the door height less 3 feet. Ensure the proper length of chain has been provided. If the manual hoist is being added to pre-installed operator, it will be necessary to move the operator and track assembly back (into the garage) approximately 6" to allow for installation of the new front drive assembly. 1 WARNING 1. Existing Installation: Using proper temporary support for the operator and track assembly, disassemble the existing front bracket and idler assembly from the track end (Refer to owner's manual if necessary). [. . . ] Determine the chain hoist location and cut the shaft to the desired length. WARNING WARNING To prevent possible SERIOUS INJURY or DEATH, disconnect electric power to operator BEFORE installing. ALL installations and electrical connections MUST be made by a qualified individual. CAUTION 7. Install the 48B14 sprocket on one end of the shaft, (Figure 2). Align sprocket flush with end of shaft, drill a 1/4" diameter hole through sprocket hub and shaft. Secure using 1/4" x 1-3/4" rollpin. Slide the two shaft support bearings onto the shaft. Drill and pin the 40 tooth drive sprocket in desired location on the opposite end of the shaft. Supporting the far end of the shaft, butt together the two 48B14 sprockets and connect using the #41 chain provided. Position the bearings on shaft so that one bearing is at the mid point and the other as close to the 40 tooth sprocket as possible. With the shaft level and using suitable hardware, secure the bearings. 10. Vertically align the hand chain sprocket with the 40 tooth drive sprocket. With the chain in place, and using suitable hardware, secure the hoist housing. Align and secure the hand chain retaining bracket.
