Additional Safety Precautions - Hilti DD 200 / DD-HD 30 Manual De Usuario

▶ 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.

Additional safety precautions

Personal safety
▶ Tampering with or modification of the machine is not permitted.
▶ The machine is not intended for use by inexperienced persons who have received no special
training.
▶ Keep the machine out of reach of children.
▶ Avoid touching rotating parts. Switch the machine on only after it is in position at the workpiece.
Touching rotating parts, especially rotating accessory tools, may lead to injury.
▶ Avoid skin contact with drilling slurry.
▶ Dust from materials, such as paint containing lead, some kinds of wood, concrete / masonry / stone
containing silica, and minerals as well as metal, may be injurious to health. Contact with or inhalation of
the dust may cause allergic reactions and/or respiratory or other diseases to the operator or bystanders.
Certain kinds of dust are classified as carcinogenic such as oak and beech dust, especially in conjunction
with additives for wood conditioning (chromate, wood preservative). Material containing asbestos must
only be handled by specialists. Use a dust removal system that is as effective as possible. Accordingly,
use a suitable vacuum cleaner of the type recommended by Hilti for wood dust and/or mineral dust and
which is designed for use with this power tool. Ensure that the workplace is well ventilated. The use
of a dust mask suitable for the particular type of dust is recommended. Observe national regulations
applicable to the materials on which you intend to use the machine.
▶ The diamond core drilling machine and the diamond core bit are heavy pieces of equipment. There is a
risk of crushing parts of the body. The user and any other persons in the vicinity must wear suitable
eye protection, a hard hat, ear protection, protective gloves and safety footwear while the machine
is in use.
Careful handling and use of electric tools
▶ Make sure that the machine is correctly fastened in the drill stand.
▶ Take care to ensure that an end stop is always fitted to the drill stand. The safety-relevant end-stop
function becomes inoperative if this component is not fitted.
▶ Ensure that the accessory tools used have a mounting system that is compatible with the drilling
machine and that they are secured in the chuck correctly.
Electrical safety
▶ Avoid using extension cords with multiple power outlets and the simultaneous use of several
machines connected to one extension cord.
▶ The machine may be operated only when connected to an adequately-rated power supply equipped
with an earth (ground) conductor.
▶ Before beginning work, check the working area (e.g. using a metal detector) to ensure that no
concealed electric cables or gas and water pipes are present. External metal parts of the machine
may become live, for example, when an electric power line is damaged accidentally. This presents a
serious risk of electric shock.
▶ Make sure that the supply cord is not pinched and damaged as the carriage advances.
▶ Never operate the machine without the accompanying PRCD (machines without PRCD: Never
operate the machine without an isolating transformer). Test the PRCD each time before use.
▶ Check the machine's supply cord at regular intervals and have it replaced by a qualified specialist
if found to be damaged. If the machine's supply cord is damaged it must be replaced with
a specially-prepared and approved supply cord available from Hilti Customer Service. Check
extension cords at regular intervals and replace them if found to be damaged. Do not touch the
supply cord or extension cord if it is damaged while working. Disconnect the supply cord plug
from the power outlet. Damaged supply cords or extension cords present a risk of electric shock.
▶ Never operate the machine when it is dirty or wet. Dust (especially dust from conductive materials)
or dampness adhering to the surface of the machine may, under unfavorable conditions, lead to electric
shock. Dirty or dusty machines should thus be checked by Hilti Service at regular intervals, especially if
used frequently for working on conductive materials.
