3. Machine Anchoring Operation
① Attach a 22mm bit to the hammer drill and make a hole at the center of the circle
marked as the anchor position.
▪ As a lot of dust is generated when making a hole i
n concrete, remove the dust with
the vacuum cleaner from the entrance of the hole.
② Make sure that the hammer drill is perpendicular to the ground surface, and make a
hole with a depth of 150mm.
③ Use an air gun to blow out the dust from inside the hole.
▪ When using the air gun, simultaneously operate the vacuum cleaner at the hole’s
entrance in order to prevent the dust from scattering.
▪ If necessary, remove the dust thoroughly using a brush.
