Diamond Drill Safety Warnings; Additional Safety Instructions - Hilti DD 30-W Manual De Instrucciones

▶ Use the power tool, accessories and tool bits etc. in accordance with these instructions, taking
into account the working conditions and the work to be performed. Use of the power tool for
operations different from those intended could result in a hazardous situation.
▶ Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles and
grasping surfaces do not allow for safe handling and control of the tool in unexpected situations.
Service
▶ Have your power tool serviced by a qualified repair person using only identical replacement parts.
This will ensure that the safety of the power tool is maintained.

Diamond drill safety warnings

▶ When performing drilling that requires the use of water, route the water away from the operator's
work area or use a liquid collection device. Such precautionary measures keep the operator's work
area dry and reduce the risk of electrical shock.
▶ Operate power tool by insulated grasping surfaces, when performing an operation where the
cutting accessory may contact hidden wiring or its own cord. Cutting accessory contacting a "live"
wire may make exposed metal parts of the power tool "live" and could give the operator an electric
shock.
▶ Wear hearing protection when diamond drilling. Exposure to noise can cause hearing loss.
▶ When the bit is jammed, stop applying downward pressure and turn off the tool. Investigate and
take corrective actions to eliminate the cause of the bit jamming.
▶ When restarting a diamond drill in the workpiece check that the bit rotates freely before starting. If
the bit is jammed, it may not start, may overload the tool, or may cause the diamond drill to release from
the workpiece.
▶ 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.
Applies only to hand-guided operation:
▶ 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.
Applies only to drill stand operation:
▶ Do not use this tool for overhead drilling with water supply. Water entering the power tool will
increase the risk of electric shock.

Additional safety instructions

Personal safety
▶ During hand-held use, always hold the machine securely with both hands on the grips provided.
▶ The machine and the diamond core bit are heavy. There is a risk of crushing parts of the body. Wear
a hard hat, protective gloves and safety footwear.
▶ Keep the grips dry, clean and free from oil and grease.
▶ Improve the blood circulation in your fingers by relaxing your hands and exercising your fingers
during breaks between working.
▶ Avoid touching rotating parts. Switch the machine on only after bringing it into position at the
workpiece. Touching rotating parts, especially rotating accessory tools, may lead to injury.
▶ Always lead the supply cord, the extension cord and, if applicable, the suction hose away from the
machine to the rear when working. This helps to avoid tripping over the cord or hose while working.
▶ Do not allow drilling slurry to come into contact with the skin or eyes. Wear protective gloves and
protective glasses.
▶ Children are not permitted to play with the machine and must be instructed accordingly.
