5 Safety instructions
NOTE
The safety rules in section 5.1 contain all general safety
rules for power tools which, in accordance with the
applicable standards, must be listed in the operating
instructions. Accordingly, some of the rules listed may
not be relevant to this tool.
5.1 General power tool safety warnings
a)
WARNING
Read all safety warnings and instructions. Failure
to follow the warnings and instructions may result
in electric shock, fire and/or serious injury. Save all
warnings and instructions for future reference.
The term “power tool” in the warnings refers to
your mains-operated (corded) power tool or battery-
operated (cordless) power tool.
5.1.1Workareasafety
a) Keep work area clean and well lit. Cluttered or dark
areas invite accidents.
b) Do not operate power tools in explosive atmo-
spheres, such as in the presence of flammable
liquids, gases or dust. Power tools create sparks
which may ignite the dust or fumes.
c) Keep children and bystanders away while operat-
ing a power tool. Distractions can cause you to lose
control.
5.1.2 Electrical safety
a) Power tool plugs must match the outlet. Never
modify the plug in any way. Do not use any adapter
plugs with earthed (grounded) power tools. Un-
modified plugs and matching outlets will reduce risk
of electric shock.
b) Avoid body contact with earthed or grounded
surfaces such as pipes, radiators, ranges and
refrigerators. There is an increased risk of electric
shock if your body is earthed or grounded.
c) Do not expose power tools to rain or wet condi-
tions. Water entering a power tool will increase the
risk of electric shock.
d) Do not abuse the cord. Never use the cord for
carrying, pulling or unplugging the power tool.
Keep cord away from heat, oil, sharp edges or
moving parts. Damaged or entangled cords increase
theriskofelectricshock.
e) When operating a power tool outdoors, use an
extension cord suitable for outdoor use. Use of
a cord suitable for outdoor use reduces the risk of
electric shock.
f) If operating a power tool in a damp location is
unavoidable, use a residual current device (RCD)
protected supply. Use of an RCD reduces the risk
of electric shock.
5.1.3 Personal safety
a) Stay alert, watch what you are doing and use
common sense when operating a power tool. Do
not use a power tool while you are tired or under
the influence of drugs, alcohol or medication. A
moment of inattention while operating power tools
may result in serious personal injury.
b) Use personal protective equipment. Always wear
eye protection. Protective equipment such as dust
mask, non-skid safety shoes, hard hat, or hearing
protection used for appropriate conditions will reduce
personal injuries.
c) Prevent unintentional starting. Ensure the switch
is in the off‐position before connecting to power
source and/or battery pack, picking up or carrying
the tool. Carrying power tools with your finger on the
switch or energising power tools that have the switch
on invites accidents.
d) Remove any adjusting key or wrench before turn-
ing the power tool on. A wrench or a key left at-
tached to a rotating part of the power tool may result
in personal injury.
e) Do not overreach. Keep proper footing and bal-
ance at all times. This enables better control of the
power tool in unexpected situations.
f) Dress properly. Do not wear loose clothing or
jewellery. Keep your hair, clothing and gloves
away from moving parts. Loose clothes, jewellery
or long hair can be caught in moving parts.
g) If devices are provided for the connection of dust
extraction and collection facilities, ensure these
are connected and properly used. Use of dust
collection can reduce dust-related hazards.
5.1.4 Power tool use and care
a) Do not force the power tool. Use the correct
power tool for your application. The correct power
tool will do the job better and safer at the rate for
which it was designed.
b) Do not use the power tool if the switch does not
turn it on and off. Any power tool that cannot be
controlled with the switch is dangerous and must be
repaired.
c) Disconnect the plug from the power source
and/or the battery pack from the power tool
before making any adjustments, changing
accessories, or storing power tools. Such
preventive safety measures reduce the risk of
starting the power tool accidentally.
d) Store idle power tools out of the reach of chil-
dren and do not allow persons unfamiliar with the
power tool or these instructions to operate the
power tool. Power tools are dangerous in the hands
of untrained users.
e) Maintain power tools. Check for misalignment or
binding of moving parts, breakage of parts and
any other condition that may affect the power
tool’s operation. If damaged, have the power tool
repaired before use. Many accidents are caused by
poorly maintained power tools.

Printed: 08.07.2013 | Doc-Nr: PUB / 5130115 / 000 / 02

f) Keep cutting tools sharp and clean. Properly main-
tained cutting tools with sharp cutting edges are less
likely to bind and are easier to control.
g) Use the power tool, accessories and tool bits etc.
in accordance with these instructions taking into
account the working conditions and the work to
be performed. Use of the power tool for opera-
tions different from those intended could result in a
hazardous situation.
5.1.5 Battery tool use and care
a) Recharge only with the charger specified by the
manufacturer. A charger that is suitable for one type
of battery pack may create a risk of fire when used
with another battery pack.
b) Use power tools only with specifically designated
battery packs. Use of any other battery packs may
create a risk of injury and fire.
c) When battery pack is not in use, keep it away
from other metal objects, like paper clips, coins,
keys, nails, screws or other small metal objects,
that can make a connection from one terminal to
another. Shorting the battery terminals together may
cause burns or a fire.
d) Under abusive conditions, liquid may be ejected
from the battery, avoid contact. If contact acci-
dentally occurs, flush with water. If liquid contacts
eyes, additionally seek medical help. Liquid ejected
from the battery may cause irritation or burns.
5.1.6 Service
a) Have your power tool serviced by a qualified repair
person using only identical replacement parts.
This will ensure that the safety of the power tool is
maintained.
5.2 Hammer safety warnings
a) Wear ear protectors. Exposure to noise can cause
hearing loss.
b) Use auxiliary handles, if supplied with the tool.
Loss of control can cause personal injury.
c) Hold power tool by insulated gripping surfaces,
when performing an operation where the cutting
accessory may contact hidden wiring. Cutting ac-
cessory contacting a "live" wire may make exposed
metal parts of the power tool "live" and could give
the operator an electric shock.
5.3 Additional safety precautions
5.3.1 Personal safety
a) Hold power tool by insulated gripping surfaces
when performing an operation where the cutting
accessory may contact hidden wiring or 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.
b) Always hold the power tool securely with both
hands on the grips provided. Keep the grips dry,
clean and free from oil and grease.
c) Breathing protection must be worn if the power
tool is used without a dust removal system for
work that creates dust.
d) Improve the blood circulation in your fingers by
relaxing your hands and exercising your fingers
during breaks between working.
e) Avoid touching rotating parts. Switch the power
tool on only after bringing it into position at the
workpiece. Touching rotating parts, especially rotat-
ing insert tools, may lead to injury.
f) Activate the safety lock (forward / reverse switch
in the middle position) before storing or trans-
porting the power tool.
g) Children must be instructed not to play with the
power tool.
h) The power tool is not intended for use by children,
by debilitated persons or those who have received
no instruction or training.
i) WARNING: Some dust created by grinding, sand-
ing, cutting and drilling contains chemicals known
to cause cancer, birth defects, infertility or other
reproductive harm; or serious and permanent res-
piratory or other injury. Some examples of these
chemicals are: lead from lead-based paints, crys-
talline silica from bricks, concrete and other masonry
products and natural stone, arsenic and chromium
from chemically-treated lumber. Your risk from these
exposures varies, depending on how often you do
this type of work. To reduce exposure to these
chemicals, the operator and bystanders should
work in a well-ventilated area, work with ap-
proved safety equipment, such as respiratory pro-
tection appropriate for the type of dust generated,
and designed to filter out microscopic particles
and direct dust away from the face and body.
Avoid prolonged contact with dust. Wear protec-
tive clothing and wash exposed areas with soap
and water. Allowing dust to get into your mouth,
eyes, or to remain on your skin may promote absorp-
tion of harmful chemicals.
5.3.2 Power tool use and care
a) Secure the workpiece. Use clamps or a vice to
secure the workpiece. The workpiece is thus held
more securely than by hand and both hands remain
free to operate the power tool.
b) Check that the insert tools used are compatible
with the chuck system and that they are secured
in the chuck correctly.
5.3.3 Cordless tool use and care
a) Ensure the switch is in the off position before
inserting battery pack. Inserting the battery pack
into power tools that have the switch on invites
accidents.
b) Observe the special instructions applicable to the
transport, storage and use of Li-ion batteries.
c) Do not expose batteries to high temperatures or
fire. This presents a risk of explosion.
en

Printed: 08.07.2013 | Doc-Nr: PUB / 5130115 / 000 / 02

d) Do not disassemble, squash or incinerate bat-
teries and do not subject them to temperatures
over 80°C (176°F). A risk of fire, explosion or in-
jury through contact with caustic substances may
otherwise result.
e) Do not use batteries other than those approved
for use with the applicable power tool or appli-
ance. Use of other batteries or use of the battery for
purposes for which it is not intended presents a risk
of fire and explosion.
f) Do not charge or continue to use damaged bat-
teries (e.g. batteries with cracks, broken parts,
bent or pushed-in and/or pulled-out contacts).
g) Avoid short-circuiting the battery. Check that the
terminals on the battery and in the power tool
are free from foreign objects before inserting the
battery in the power tool. Short circuiting the bat-
tery terminals presents a risk of fire, explosion and
chemical burns.
h) Avoid ingress of dampness.Dampness may cause
a short circuit resulting in a risk of burning injury or
fire.
i) If the battery gets too hot to touch, this may indicate
that it is faulty. Place the tool in a location where
it can be kept under observation, well away from
flammable materials, and allow it to cool down.
Contact Hilti Service after the battery has been
allowed to cool.
5.3.4 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, when an electric cable is damaged
accidentally. This presents a serious risk of electric shock.
5.3.5 Work area safety
a) Ensure that the workplace is well lit.
b) Ensure that the workplace is well ventilated. Ex-
posure to dust at a poorly ventilated workplace may
result in damage to the health.
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.
5.3.6 Personal protective equipment
The user and any other persons in the vicinity must
wear ANSI Z87.1-approved eye protection, a hard
hat, ear protection, protective gloves and breathing
protection while the machine is in use.

7.2.3 Hammer drilling 
1. Turn the function selector switch until it engages in
the “Hammer drilling” position.
2. Bring the side grip into the desired position and
check that it is fitted correctly and secured.
3. Fit the battery.
NOTE Before beginning the work, check that the
battery is fitted securely to the tool. If it is not fitted
securely, the battery could fall out while you are
working with the tool and cause injury.
4. Position the power tool and drill bit at the point
where the hole is to be drilled.
5. Press the control switch slowly (drill at a low speed
until the drill bit centers itself in the hole).
6. Press the control switch fully to continue drilling with
full power.
7. Do not apply excessive pressure.Thiswillnotin-
crease the power tool’s hammering performance.
Lower pressure extends the life of the insert tool.
8. Reduce drilling speed shortly before breaking
through in order to avoid damage to the surface at
the rear side.
7.2.4 Active Torque Control 
In addition to the mechanical slip clutch, the tool is also
equipped with ATC (Active Torque Control). This system
offers additional comfort while drilling as it causes rapid
shutdown upon sudden rotation of the power tool about
the drill bit axis, e.g. when the drill bit sticks due to
hitting a rebar or when the drill bit is tilted unintention-
ally. If the ATC system has triggered, restart the power
tool by releasing the control switch and then pressing
it again. Always choose a working position in which the
electric tool, when turning clockwise, is free to rotate
in a counterclockwise direction (as seen by the oper-
ator). In counterclockwise rotation, the tool reacts and
turns clockwise. If rotation is not possible, active torque
control cannot react.
7.2.5 Chiseling
NOTE
The chisel can be adjusted to 12 different positions
(in 30° increments). This ensures that flat chisels and
shaped chisels can always be set to the optimum working
position.
7.2.5.1 Chisel position adjustment
CAUTION
Do not operate the power tool when the selector
switch is set to "Chisel adjustment".
1. Turn the function selector switch until it engages in
the “Chisel adjustment” position. Do not operate the
function selector switch while the motor is running.
2. Bring the side grip into the desired position and
check that it is fitted correctly and secured.
3. Rotate the chisel to the desired position.
7.2.5.2 Locking the chisel
1. Turn the function selector switch until it engages in
the “Chiseling” position. Do not operate the function
selector switch while the motor is running.
7.2.5.3 Chiseling
1. Insert the battery.
2. Position the tip of the chisel at the point where
chiseling is to begin.
3. Press the control switch.
7.2.6 Reading the charge status LED display on
Li‑ion batteries 
NOTE
During and immediately after work (approx. 3 seconds), it
is not possible to check the charge status. If LED 1 blinks
this indicates that the battery is either fully discharged or
is too hot (temperature above 80°C (176°F)). The battery
must then be inserted in the charger.Ifall4LEDsflash,
this indicates that the power tool has been overloaded or
has overheated.
The Li-ion battery features a charge status LED display.
The charge status is indicated by the LEDs on the battery
during charging (please refer to the operating instructions
for the charger). When the battery is not in use, pressing
one of the battery release buttons or inserting the battery
into the power tool causes the battery charge status to
be displayed by the four LEDs for three seconds.
See section: 2.10 Li‑ion battery charge status
8 Care and maintenance
CAUTION
Before beginning cleaning, remove the battery from
the power tool in order to prevent unintentional start-
ing.
8.1Careofinserttools
Clean off dirt and dust deposits adhering to the insert
tools and protect them from corrosion by wiping the
insert tools from time to time with an oil-soaked rag.
8.2 Care of the power tool
CAUTION
Keep the power tool, especially its grip surfaces,
clean and free from oil and grease. Do not use clean-
ing agents which contain silicone.
The outer casing of the power tool is made from impact-
resistant plastic. Sections of the grip are made from a
synthetic rubber material.

Never operate the power tool when the ventilation slots
are blocked. Clean the ventilation slots carefully using
a dry brush. Do not permit foreign objects to enter the
interior of the power tool. Clean the outside of the power
tool at regular intervals with a slightly damp cloth. Do
not use a spray, steam pressure cleaning equipment or
running water for cleaning. This may negatively affect the
electrical safety of the power tool.
8.3 Cleaning or replacing the dust shield
Clean the dust shield on the chuck with a dry, clean
cloth at regular intervals. Clean the sealing lip by wiping it
carefully and then grease it again lightly with Hilti grease.
It is essential that the dust shield is replaced if the sealing
lip is found to be damaged. Push the tip of a screwdriver
under the edge of the dust shield and prise it out toward
the front. Clean the area of the chuck in contact with dust
shield and then fit a new dust shield. Press it in firmly
until it engages.
8.4 Care of the Li-ion battery
Avoid entrance of moisture.
Charge the battery fully before using it for the first time.
In order to achieve maximum battery life, stop discharging
the battery as soon as a significant drop in performance
is noticed.
NOTE
If use of the power tool continues, further battery dis-
charge will be stopped automatically before the battery
cells suffer damage.
Charge the battery with the Hilti charger approved for use
with Li-ion batteries.
NOTE
- A conditioning charge (as is required with NiCd or
NiMH batteries) is not necessary.
- Interruption of the charging procedure has no negative
effect on battery life.
- Charging can be started at any time with no negative
effect on battery life. There is no memory effect (as
with NiCd or NiMH batteries).
- For best results, batteries should be stored fully
charged in a cool dry place. Avoid charging the battery
in places subject to high ambient temperatures (e.g. at
a window) as this has an adverse effect on battery life
and increases the rate of self-discharge.
- If the battery no longer reaches full charge, it may
have lost capacity due to aging or overstressing. It
is possible to continue working with a battery in this
condition but it should be replaced in good time.
8.5 Maintenance
WARNING
Repairs to the electrical section of the power tool may
be carried out only by trained electrical specialists.
Check all external parts of the power tool for damage
at regular intervals and check that all controls operate
faultlessly. Do not operate the power tool if parts are
damaged or when the controls do not function faultlessly.
If necessary, the power tool should be repaired by Hilti
Service.
8.6 Checking the power tool after care and
maintenance
