Put a hammer drill with a Ф14 drill bit on a marked hole position
perpendicularly against the wall and drill holes with a depth of 52-60 mm.
NOTICE
To prevent dust inhalation or contact with eyes, wear safety goggles and an anti-dust
respirator when drilling holes.
Vacuum any dust in or around the holes by using a vacuum cleaner and measure the hole
distance. If the holes are inaccurately positioned, drill holes again.

Vertically insert an expansion bolt into a hole, and knock the expansion bolt
completely into the hole by using a rubber mallet.

Remove the M10x60 bolt, spring washer, and flat washer by rotating them
counterclockwise.

Level the front of the expansion sleeve with the concrete wall after removing the bolt,
spring washer, and flat washer. Otherwise, the rear panel will not be securely installed on
the concrete wall.
