Hilti DD 160 Manual De Instrucciones Original página 11

▶ 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.
2.2 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 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.
▶ Do not use this tool for overhead drilling with water supply. Water entering the power tool will
increase the risk of electric shock.
2.3 Additional safety instructions
Personal safety
▶ Do not tamper with or attempt to make alterations to the machine.
▶ The machine is not intended for use by debilitated persons who have received no special training.
▶ Keep the machine out of reach of children.
▶ Do not touch rotating parts. Switch the machine on only after it is in position at the workpiece.
Touching rotating parts, especially rotating accessory tools, can result in injury.
▶ Avoid skin contact with drilling slurry.
▶ Dust from materials such as lead-based paint, certain types of wood and concrete/masonry/stone
containing quartz, minerals or metal can be harmful to health. Contact with or inhalation of the dust can
cause allergic reactions and/or respiratory or other diseases among operators or bystanders. Certain
kinds of dust such as oakwood and beechwood dust are classified as carcinogenic, especially in
conjunction with additives for wood conditioning (chromate, wood preservative). Only specialists are
permitted to handle material containing asbestos. Use as effective a dust removal system as possible.
To achieve a high level of dust collection, use a suitable vacuum extractor of the type recommended by
Hilti for wood dust and/or mineral dust and which is designed for use with this power tool. Make sure
that the workplace is well ventilated. It is advisable to wear a respirator appropriate for the type of dust
generated. Comply with national regulations applicable to the materials you will be working with.
▶ The diamond core drilling machine and the diamond core bit are heavy. There is a risk of crushing parts
of the body. The user and persons in the vicinity must wear suitable protective goggles, a hard hat,
ear defenders, protective gloves and protective footwear while the machine is in use.
Power tool use and care
▶ Make sure that the machine is correctly secured to the drill stand.
▶ Always make sure that an end stop is installed on the drill stand as otherwise the safety-relevant
end-stop function is not implemented.
▶ Check that accessory tools are compatible with the machine's chuck/drive system and that they
are installed and secured correctly.
