wood preservative). Material containing asbestos
must only be treated by specialists. Where the
use of a dust extraction device is possible it
shall be used. To achieve a high level of dust
collection, use a suitable vacuum cleaner of the
type recommended by Hilti for wood dust and/or
mineral dust together with this tool. Ensure that
the workplace is well ventilated. The use of a
dust mask of filter class P2 is recommended.
Follow national requirements for the materials
you want to work with.
5.3.2 Electrical safety
a) 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, when
an electric cable is damaged accidentally. This
presents a serious risk of electric shock.
b) Check the power tool's supply cord at regular
intervals and have it replaced by a qualified
specialist if found to be damaged. If the power
tool's supply cord is damaged it must be re-
placed with a specially-prepared 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.
c) Dirty or dusty power tools which have been
used frequently for work on conductive mater-
ials should be checked at regular intervals at
a Hilti Service Center. Under unfavorable cir-
cumstances, dampness or dust adhering to the
surface of the power tool, especially dust from
conductive materials, may present a risk of elec-
tric shock.
d) When working outdoors with an electric tool
check to ensure that the tool 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.
e) Use of a ground fault circuit interrupter (RCD re-
sidual current device) with a maximum tripping
current of 30 mA is recommended.
f) Switch the power tool off and unplug the supply
cord in the event of a power failure or inter-
ruption in the electric supply. This will prevent
accidental restarting when the electric power re-
turns.
5.3.3 Work area
a) Ensure that the workplace is well ventilated.
Exposure to dust at a poorly ventilated workplace
may result in damage to the health.
b) Keep the workplace tidy. Objects which could
cause injury should be removed from the work-
ing area. Untidiness at the workplace can lead to
accidents.
c) If the work involves breaking right through, take
the appropriate safety measures at the opposite
side. Parts breaking away could fall out and / or
fall down and injure other persons.
d) Approval must be obtained from the site en-
gineer or architect prior to beginning the work.
Work on buildings and other structures may in-
fluence the statics of the structure, especially
when steel reinforcing bars or load-bearing
components are cut through.
5.3.4 Personal protective equipment
The user and any other persons in the vicinity
must wear suitable eye protection, a hard hat, ear
protection, protective gloves, safety footwear and
respiratory protection while the tool is in use.
