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,
