To prevent dust inhalation or contact with eyes, wear safety goggles and an anti-dust
respirator when drilling holes.

Clean up any dust in and around the holes using a vacuum cleaner and measure the
distance between holes. If the holes are inaccurately positioned, drill new set of the holes.

Level the head of the expansion sleeve with the concrete wall after removing the bolt,
spring washer, and flat washer. Otherwise, the mounting bracket will not be securely
installed on the concrete wall.
