For a compact installation the operator arm will have to be shortened.
1. Take the operator arm apart and remove the inner sleeves from the
outer tubing.
2. Cut the outer tubing of the operator arm sections to the lengths
shown.
3. Put the arm back together and adjust the arm to the measurements
as shown. Use the set screws on the arm to temporarily hold the
arm in place while determining the correct measurements.

Step 4 Position the Gate Bracket

NOTE: It may be necessary to attach horizontal reinforcement to the gate before attaching the gate bracket. Use the set screws on the arm to temporarily
hold the arm in place while determining the correct measurements.
1. Position the operator arm onto the output shaft so that the pin slides into the slot.
2. Measure 33" (83.8 cm) along the gate length from the gate hinge center.
3. Measure 27.5" (69.9 cm) up from the concrete pad to the gate hinge position on the gate as shown.
