▶ If a PRCD is supplied with the power tool, never operate the power tool without the PRCD connected
(for GB versions, never operate without an isolating transformer). Test the PRCD each time before use.
▶ Check the condition of the supply cord at regular intervals. 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.
▶ Use of a ground fault circuit interrupter (residual current device, RCD) with a maximum tripping current
of 30 mA is recommended. When working outdoors with an electric tool or machine, check to ensure
that the tool or machine is connected to the electric supply by way of a ground fault circuit interrupter
(RCD) with a rating of max. 30 mA (tripping current). Use of a ground fault circuit interrupter reduces the
risk of electric shock.
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.
