Caution:
1) Hold the drilling bit vertical to the wall during drilling. Hold tight the drillstock with two hands to keep it in
the right direction, as vibrations may lead to damaged wall and the hole not straight.
2) The holes should be 52mm~60mm deep and should have the same depth. Otherwise, the expansion
bolts can not be secured.
3) If the wall is too hard and smooth to settle the drill bit, punch a pit with a chisel to help positioning the
hole.
3) Remove the bolt sleeve and nut and put the sleeve and nut vertically into the hole
(before this, the guiding fins should be installed on the slots of the sleeve).
Hammer the bolt sleeve until it completely goes into the ground. Figure 2 -12
shows the installation of the bolt sleeve and nut.
