2. Hammer safety warnin s
a) Wear ear protectors. Exposure to noise can cause
hearing loss.
b) Use auxiliary handle(s), if supplied with the tool.
Loss of control can cause personal injury.
c) Hold power tool by insulated rippin surfaces,
when performin an operation where the cuttin
accessory may contact hidden wirin ir 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.
3. Additional safety rules
3.1 Personal safety
a) Always hold the tool with both hands on the grips
provided. Keep the grips dry, clean and free from
oil and grease.
b) Exercise your fingers during pauses between work
to improve the blood circulation in your fingers.
c) Avoid contact with rotating parts. Switch the tool on
only once it has been brought into the working posi-
tion close to the workpiece.
d) Breathing protection must be worn when the tool is
used without a dust removal system for work that
creates dust.
e) To avoid tripping and falling when working, always
lead the sypply cord, extension cord and dust extrac-
tion hose away to the rear.
f) When drilling or chiseling through-holes, check that
no person is present in the danger area immedi-
ately behind the work surface.
g) Hold tool by insulated gripping surfaces when per-
forming an operation where the cutting tool may
contact hidden wiring or its own cord. Contact with
a “li e” wire will make exposed metal parts of the tool
“li e” and shock the operator.
h) Children must be instructed not to play with the tool.
i) The tool is not intended for use by children, by debil-
itated persons or those who have received no instruc-
tion or training.
j) Dust from material such as paint containing lead, some
wood species, minerals and metal may be harmful.
Contact with or inhalation of the dust may cause aller-
gic reactions and/or respiratory diseases to the oper-
ator or bystanders. Certain kinds of dust are classi-
fied as carcinogenic such as oak and beech dust espe-
cially in conjunction with additi es for wood condi-
tioning (chromate, wood preser ati e). Material con-
taining asbestos must only be treated by specialists.
Where the use of a dust extraction device is possi-
ble 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 miner-
al dust together with this tool. Ensure that the work-
place 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.
3.2 Power tool use and care
a) Secure the workpiece. Use clamps or a vice to hold
the workpiece in place. The workpiece is thus held
more securely than by hand and both hands remain
free to operate the tool.
b) Ensure that the insert tools used are equipped with
the appropriate connection end system and that
they are properly fitted and secured in the chuck.
c) In the event of a power faillure, switch the tool off
and unplug the supply cord. This prevents inadver-
tent starting when the power returns.
d) In the event of an interruption in the electric supply
and before laying the tool down each time, check
that the lockbutton for sustained operation has been
released. Release the lockbutton if necessary. Fail-
ure to observe this point could cause the tool to start
une pectedly when the power returns.
e) Do not apply an excessive quantity of grease to the
drill bit connection end. E cess grease may other-
wise be forced out of the chuck during operation.
3.3 Electrical safety
a) Before beginning work, check the working area (e.g.
with a metal detector) to ensure that no concealed
electric cables or gas and water pipes are present.
E ternal metal parts of the tool may become live if,
for e ample, an electric cable is damaged inadvertenly.
This presents a serious risk of electric shock.
b) Check the condition of the supply cord and its plug
connections and have it replaced by a qualified elec-
trician if damage is found. Check the condition of
the extension cord and replace it if damage is found.
Do not touch the supply in the event of it suffering
damage while working. Disconnect the supply cord
plug from the socket. Damaged supply cords and
e tension cords present a risk of electric shock.
c) Dirty or dusty electric tools should thus be checked
at a Hilti service center at regular intervals, espe-
cially if used frequently for working on conductive
materials. Dust (especially dust from conductive
materials) or dampness adhering to the surface of
the tool may under unfavorable conditions present
a risk of electric shock.
3.4 Work area
a) Ensure that the workplace is well lit.
b) Ensure that the workplace is well ventilated.
Poorly ventilated workplaces may be injurious to the
health due to e poseure to dust.
3. Personal protective equipment
The user and any other persons in the vicinity must
wear suitable eye protection a hard hat ear protection
and protective gloves when the tool is in use. Breath-
ing protection must be worn if no dust removal sys-
tem is used.
