remove the dust inside and outside the holes with a vacuum cleaner, and then
check the distance among the holes. Whenever big errors occur, the relevant
holes must be relocated and drilled again.
Caution:
1) Hold the drilling bit vertical to the floor during drilling. Hold tight the drillstock with two hands to keep it in
the right direction, as vibrations may lead to damaged floor and the hole not straight.
2) The hole depth should be the length of the expansion bolt sleeve plus the drill bit. The hole depths of
respective holes should be consistent. Before measuring the hole depth, remove the dust inside the hole
and measure the hole depth. Remove the dust with a vacuum cleaner before drilling.
3) If the floor is too hard and smooth to settle the drill bit, punch a pit with a chisel to help positioning the
hole.
4) Unfix the spring washer, nut and plain washer. Put the expansion bolt into the hole
and knock directly on the bolt with a hammer (such as nail hammer) until the bolt is
completely driven into the floor. Then, put the nut on the bolt and tighten it until the
bolt is expanded slightly so as to avoid it getting loose.
