CONTROL ARM ASSEMBLY
1. Assemble the control arm to the operator hub.
2. Push up the manual release pin from below the hub and
through the control arm. Retain in place with clevis pin. Use
3/8" washers to reduce play between the clevis pin and the top
of the control arm.
3. When the manual release pin is allowed to drop down, the
control arm should swivel freely about the hub. Leave the arm
free to pivot at this time.
4. Fasten the arm stop to the extension arm. Left hand or right
hand installations call for mounting the arm stop on opposite
sides of the extension arm.
5. Secure the extension arm to the control arm using the
hardware provided.
6. Assemble the gate bracket to the extension arm as shown.
7. Put the gate in the fully closed position and extend the arm
assembly out to the closed gate. Mark the point on the gate
where the gate bracket will mount to the gate.
8. The gate bracket must be installed on a structural member of
the gate. If require, install a horizontal support on the gate at
the appropriate height.
9. Attach the gate bracket with U-bolts or by welding.
