2) Drill
holes
Step
Operation
1
Use a percussion drill with a 6-mm (0.24-in) bit to drill holes on the three markings.
Observe the following precautions when drilling:
z
Hold the drill handle with both hands, with the bit perpendicular to the wall surface, and prevent wall
damage or tilted holes.
z
The hole depth should be the anchor length plus the bit length. Each hole should have the same
depth. Remove the dust from the hole before measuring the hole depth. Use a vacuum cleaner to
prevent dust from spreading around.
z
If the wall surface is too solid and slippery to locate the bit, punch a notch first.
3) Install
anchors
Before installation, remove dust inside and around all holes with a vacuum cleaner, and then measure
the distances between holes. If there is a large error, mark and drill holes again.
