With the gate and the operator in the open position you are now ready to connect the two together. Check the manual for the proper placement and alignment of the chain bracket onto the end of the gate.
Place the bracket onto your gate and clamp it in place, (DO NOT WELD IT YET). Now run the chain through the idler sprockets and over the drive sprocket on the operator and attach the chain bolt onto the end of the chain. Place the chain bolt end through the gate bracket and screw on the nut and washer. Turn the nut on so the bolt just comes out of the nut. Adjust the bracket so that the chain is level with the ground and lined up parallel with the gate and drive sprockets. Now you can weld the bracket.
Now pull the chain back to the rear of the gate and set the rear bracket in the same manner. Cut the chain to length and attach the end bolt. Push the gate to the close position. Align the bracket and chain to be level and straight as on the front and weld the bracket. Tighten the chain by turning the end bolts and remove the slack as indicated in the manual.
Check the limit adjustment. Move the gate by hand to the full open and close positions. If necessary adjust the limit nuts so that they are depressing the limit switch in each position.
You are now ready to run your operator.
Cycle the gate back and forth several times. Make small adjustments to the open and close limit settings until you have the gate stopping in the correct place without hitting the stops at either end.
