Precautions
Pay attention to the following points when drilling holes:
● If the oor is too hard and smooth to position the drill bit, use a nail punch
and hammer to create an indentation for the mounting holes. Then use the
drill bit to
nish drilling holes.
● Keep the drill bit vertical with the ground and hold the drill stock with both
hands. Avoid shaking the drill stock; otherwise, the inclined drill bit will
damage the oor.
● Drill all holes to the same depth.
Procedure
Step 1 Install a Ф16 drill bit on the hammer drill.
Step 2 Use the hammer drill to drill holes in the marked positions on a concrete oor.
The hole depth is the total length of the expansion sleeve and expansion nut, in
the range from 52 mm to 60 mm.
Step 3 Remove dust inside and around the mounting holes with a vacuum cleaner, as
shown in Figure 4-201.

Step 4 Measure the hole depth and distance. If the hole depth or distance does not meet
requirements, drill holes again.
