2. Additional safety rules
2.1 Personal safety
a) Wear ear protectors. Exposure to noise can cause
hearing loss.
b) Use auxiliary handles supplied with the tool. Loss
of control can cause personal injury.
c) Always hold the tool with both hands on the grips
provided. Keep the grips dry, clean and free from
oil and grease.
d) Exercise your fingers during pauses between work
to improve the blood circulation in your fingers.
e) Avoid contact with rotating parts. Switch the tool on
only once it has been brought into the working posi-
tion close to the workpiece.
f) Breathing protection must be worn when the tool is
used without a dust removal system for work that
creates dust.
g) To avoid tripping and falling when working, always
lead the sypply cord, extension cord and dust extrac-
tion hose away to the rear.
h) When drilling or chiseling through-holes, check that
no person is present in the danger area immedi-
ately behind the work surface.
2.2 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
unexpectedly when the power returns.
e) Do not apply an excessive quantity of grease to the
drill bit connection end. Excess grease may other-
wise be forced out of the chuck during operation.
2.3 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.
External metal parts of the tool may become live if,
for example, 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
extension 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.
2.4 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 exposeure to dust.
2.5 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.

Before use
It is essential that the safety precautions print-
ed in these operating instructions are read and observed.
Fitting the side handle
1.Unplug the tool from the mains socket.
2. Release the side handle clamping band by turning
the handle in a counter-clockwise direction.
3. Fit the side handle clamping band over the chuck
and onto the cylindrical section at the front end of
the tool.
4. Pivot the side handle into the desired position.
5. Tighten the side handle securely to prevent inad-
vertent movement.
Check that the side handle is seated securely.
The supply voltage must correspond to the infor-
mation on the type plate.
If extension cords are used: Only extension cords
of a type approved for the intended use and of adequate
cross section may be used. Failure to observe this point
may result in reduced performance of the tool and over-
heating of the cord. Damaged extension cords must be
replaced.
Use only insert tools with TE-C connection end.
Don’t exert excessive pressure on the tool. This will not
increase its hammering power.
