▶ Check that accessory tools are compatible with the machine's chuck/drive system and that they are
installed and secured correctly.
▶ Switch the appliance off and unplug the supply cord in the event of a power failure or interruption in the
electric supply. This will prevent accidental restarting when the electric power returns.
▶ Do not use damaged insert tools. Check the core bits for chipping, cracks, or heavy wear each time
before use. Do not use damaged tools. Fragments of the workpiece or a broken core bit may be ejected
and cause injury beyond the immediate area of operation.
▶ In accordance with the applications for which it is designed, the product produces a high torque. Always
use the side handle and hold the product with both hands. The user must be prepared for sudden stalling
of the accessory tool and have an absolutely secure stance with both feet.
Electrical safety
▶ 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 power tool may become
live, for example, if an electric cable is damaged accidentally. This presents a serious risk of electric
shock.
▶ Never operate the appliance without the supplied PRCD (GB version: Never operate the appliance
without an isolating transformer). Test the PRCD each time before use.
▶ Check the appliance'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 special
approved, ready-made 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. Unplug the supply cord from the power outlet. Damaged supply
cords or extension cords present a risk of electric shock.
▶ Protect yourself from electric shock. Avoid body contact with earthed or grounded objects such as pipes,
radiators, kitchen ranges and refrigerators.
▶ Do not break the connection to earth by using an adapter plug.
▶ Keep water away from the electrical parts of the power tool and from persons in the working area.
Workplace
▶ Make sure that the workplace is well ventilated. Exposure to dust at a poorly ventilated workplace may
result in damage to the health.
▶ Connect a dust removal system if the work creates dust. Drilling materials hazardous to the health (e.g.
asbestos) is not permissible.
▶ Approval must be obtained from the site engineer or architect prior to beginning drilling work. Drilling
work on buildings and other structures may influence the static equilibrium of the structure, especially
when steel reinforcing bars or load-bearing components are cut through.
▶ It is recommended that rubber gloves and non-skid shoes are worn when working outdoors.
▶ When drilling through walls, secure (cordon off) the area behind the wall, as material or the core may fall
out on the other side of the wall. When drilling through ceilings, secure (cordon off) the area below as
drilled material or the core may drop out and fall down.
