holes.
Use M12 expansion bolts to fix supports on the ground. Use a percussion drill with
Ф
16
bit to drill holes.
When drilling holes, hold the drill handle firmly with both hands, keeping the bit
perpendicular to the floor to prevent damages to the floor or tilted holes.
The depth of the holes should range from 52 mm to 60 mm (2.0 in. to 2.4 in.). All the
holes should have the same depth. After drilling a hole, use a dust collector to clean the
dust inside and outside the holes before measuring the hole depth.
The bit is difficult to position on the floor that is hard and smooth. In this case, punch a
small hole on the marks for the installation holes before drilling.
Note that the precision of marking and drilling is essential to hardware installation. Low
precision can cause many problems during installation.
Caution:
The depth of drilling is between 52 mm and 60 mm (2.0 in. to 2.4 in.). Otherwise, you
will be unable to install or fasten the expansion bolts.
