Additional Safety Precautions - Hilti DD 150-U Mode D'emploi Original

▶ When securing the drill stand with anchors and fasteners to the workpiece, ensure that the
anchoring used is capable of holding and restraining the machine during use. If the workpiece is
weak or porous, the anchor may pull out causing the drill stand to release from the workpiece.
▶ When securing the drill stand with a vacuum pad to the workpiece, install the pad on a smooth,
clean, non-porous surface. Do not secure to laminated surfaces such as tiles and composite
coating. If the workpiece is not smooth, flat or well affixed, the pad may pull away from the workpiece.
▶ Ensure there is sufficient vacuum before and during drilling. If the vacuum is insufficient, the pad
may release from the workpiece.
▶ Never perform drilling with the machine secured by the vacuum pad only, except when drilling
downwards. If the vacuum is lost, the pad will release from the workpiece.
▶ When drilling through walls or ceilings, ensure to protect persons and the work area on the other
side. The bit may extend through the hole or the core may fall out on the other side.
▶ When drilling overhead, always use the liquid collection device specified in the instructions. Do
not allow water to flow into the tool. Water entering the power tool will increase the risk of electric
shock.
