User manual LIFT-MASTER 65 9001

[. . . ] CENTER MOUNT MODIFICATION WARNING APPLICATION CAUTION This modification is available for model GH operators. For use on sectional doors only. For Use With GH Operator WARNING 659001 WARNING To prevent possible SERIOUS INJURY or DEATH, disconnect electric power to operator BEFORE installing. [. . . ] Install the driven sprocket on the door shaft and mount the operator based on the location of this sprocket. If necessary cut the unused side of the hand chain shaft off so that the drive chain does not interfere with the operator mechanism. This kit includes a length of cold rolled 1" shaft that is half the door width plus 2' based on a center mounted door operator. Install the 48B14 sprocket provided on the end of the shaft by drilling a 1/4" hole through the sprocket and shaft and secure with the 1/4" by 1-1/2" long roll pin provided. Be sure that the shaft does not extend past the end of the sprocket and that the teeth of the sprocket are at the end of the shaft (Figure 2). Raise the shaft and sprocket assembly into position so that this sprocket is butted against the sprocket on the operator hand chain shaft and support the shaft temporarily. Use the piece of #40 chain provided to connect the two sprockets together. Slide bearing onto the shaft and securely mount it so that the shaft turns freely without binding. Use the instructions below to complete the assembly of the chain hoist. 6. Cut off the excess shaft if necessary but allow for another bearing on the outside of the chain hoist to support the load when the hoist is used. Cut the disconnect sash chain close to the operator and splice in the cable provided with a cable clamp (provided). Run the cable through screw eyes and down the wall under the chain hoist. [. . . ] Drill a 5/16" hole next to the hub on the chain wheel assembly and install a 5/16" x 2-1/2" roll pin. Thick and thin washers are provided to take out extra slack or to allow more movement.
