3. Mix the concrete according to the manufacturers instructions. Pour the mixture into the
form and tamp. Level and finish the surface after pouring is complete. Do not set anchor
bolts in the concrete. Sleeve anchors should be used to secure the operator to the
pad. This allows greater flexibility in positioning the operator on the pad.
4. Allow the pad to cure for 48 hours before removing the forms or mounting the operator.
5. Once the pad has cured, place the operator-mounting stand on the pad in the proper
position; 4-inches from the front and sides of the pad and 1-inch from the rear of the pad.
The operator-mounting stand must be parallel to the gate.
6. Once the stand is in the proper position on the pad, secure the operator-mounting stand
directly to the pad using 3/8 or 1/2 x 3 sleeve anchors. Be sure that the operator-
mounting stand is parallel to the gate.
7. After securing the mounting stands to the pad, place the operator onto the mounting
stand and secure it with the hardware provided. CAUTION: the operator is heavy.
Two persons are required to lift the operator onto the mounting plate.
