POSITION THE GATE BRACKET
NOTE:
It may be necessary to attach horizontal reinforcement to the gate
before attaching the gate bracket.
1. Position the operator arm onto the output shaft so that the pin slides
into the slot.
2. Measure 46 inches along the gate length from the gate hinge center.
3. Measure 27.5 inches up from the concrete pad to the gate hinge
position on the gate as shown.
4. Make sure the operator arm is level and tack weld the gate bracket in
this position. Use the set screws on the arm to temporarily hold the
arm in place while determining the correct measurements.

STEP 4
ADJUST THE OPERATOR ARM LENGTH
NOTE:
The length of the arm can be adjusted if necessary. If adjusting the
length, ensure that both sections of the arm are adjusted proportionally.
Use the set screws on the arm to temporarily hold the arm in place while
determining the correct measurements.
1. Close the gate and measure the distance of the operator arm from the
gate bracket to the output shaft center. This distance is E.
2. Open the gate 90° (do not allow arms to scissor when open). Measure
both sections of the arm (D and C). The arm lengths are correct as
long as C+D=E (arm should be perpendicular to the gate in the open
position as shown).
