CAUTION
Take proper safety measures to protect your eyes and respiratory tract against the dust
before drilling holes.
After disassembling the expansion bolt assembly, ensure that the top of the expansion tube
is on the same level as the floor.
Use a vacuum cleaner to clear the dust inside and around the holes. If the inter-hole spacing
is too wide or too narrow, locate and drill holes again.
Tighten the expansion bolt slightly, and then put the expansion bolt assembly into the hole
vertically.
Use a rubber mallet to hammer the expansion bolt until the expansion tube is buried into
the hole.
Remove the M12x60 bolt, spring washer, and flat washer from each expansion bolt
assembly in sequence.
(2) Spring washer
Disconnect the equipotential cable from the lower part of the door.
