Step 2 Attach the Chain
DO NOT run the operator until instructed.
1. Mount gate brackets to the vertical front and rear posts of the gate.
2. Open operator door.
3. Locate the black T-shaped manual release handle attached to the gearbox in the bottom of the cabinet. Pull firmly until it latches into place.
4. Ensure that the drive and idler sprockets are in line with each other. Thread the chain through the plastic chain guide, around drive and idler
sprockets, and then through the second plastic chain guide toward front gate bracket.
5. Adjust the chain to proper length and connect the chain to the front bracket with the provided hardware. Adjust nuts on chain take-up bolts to remove
chain slack. A general rule of thumb is to leave a maximum of 1" (2.5 cm) of chain slack for every 10' (3.1 m) of chain length. Do not overtighten
chain. NOTE: The operator can be moved forward or back along the rails to ensure the chain is aligned correctly with the operator.
6. Remove the pin from the vent plug on the gear box.
7. Push the plate down to release the manual release handle to re-engage the motor and gear box.
