MOUNT THE OPERATOR

CEMENT PAD LOCATION
If no concrete surface exists to attach the gate operator to, make
a cement pad 16" x 24" x 10". The cement pad should be at least
6" in depth and extend below frost line. If it is desirable to elevate
the gate operator, it may protrude 4" or more above ground
(Figure 4). Place the shortest pad edge even with the driveway
edge. Place the longer edge of the pad 1" away from the gate.
OPTIONAL MOUNTING STAND
If the steel mounting stand will be used, place the shortest edge
of the stand 4" from the driveway edge and place the longest edge
of the stand 4-1/2" away from the gate. The top of the steel stand
may sit on the ground or the stand may be elevated to keep the
operator above snow, flooding etc. Make a post hole and cement
the stand in place, making sure the stand is level and square to
the gate (Figure 5).
POSITION GATE OPERATOR
If the steel mounting stand was used, simply bolt the gate
operator to the stand. If the operator will be mounted to a
concrete surface or pad, place the shortest edge of the operator
4" away from the edge of the driveway. Place the longer edge of
the gate operator 2-1/2" away from the gate (Figure 6).
ANCHOR THE OPERATOR
When the gate operator is correctly positioned on the concrete
surface or pad, mark the base hole locations onto the cement
with a felt tip marker or equivalent. Once marked, move the
operator to the side and drill the 4 holes using a 3/8" masonry bit.
Place the operator back into position. Insert the four sleeve
anchors into the holes and firmly tighten (Figure 7).
