Use a hammer drill with a Φ16 drill bit to drill holes with a depth ranging from 55 mm
(2.05 in.) to 60 mm (2.36 in.).
Use a vacuum cleaner to clear the dust out from inside and around the holes, and measure
the distances between holes. If any of the hole is beyond the acceptable range, mark a new
anchor point and drill a new hole.
Tighten an expansion bolt slightly and place it vertically into each hole.
Hit the expansion bolt with a rubber mallet until the expansion tube completely enters the
hole.
Turning the M12x60 bolt, spring washer, and flat washer counterclockwise, and remove
them in sequence.
CAUTION
After dismantling the expansion bolt assembly, ensure that the top of the expansion tube
is level with the concrete floor. Otherwise, the cabinet cannot be installed on the concrete
floor evenly and securely.
