Step 2 Use a hammer drill with φ6 bore to drill holes at the marked anchor points, as shown in
Figure 8-64. Use a vacuum cleaner to clean the dust inside and around the holes and measure
the distance between them. If they are inaccurately positioned, re-measure and re-drill the
holes. Then, use a rubber mallet to hit a plastic expansion sleeve into each hole.
