 ● With the gate in the CLOSED 
position, use clamps to secure the 
operator to the gate post and center 
cross member of the gate.
 ● Ensure that the operator is level.
 ● With the operator arm temporarily 
secured to the gate, check to 
ensure there is at least 2 inches 
of clearance between the operator 
arm and gate. (See illustration in

 ● Disconnect the operator arm from the 
gate bracket. 
 ● While supporting the operator, swing 
the gate and operator to the OPEN 
position.
 ● Check for recommended clearances 
and binding as shown.
 ● Ensure that the necessary arm stroke 
does not exceed 20 inches.
 ● Make adjustments to the 
mounting brackets to achieve the 
recommended clearances. 
TIP: Turning the pivot bracket over 
gives more hole alignment options for 
the gate post pivot bracket assembly.
