NOTE

The vibration emission level given in this information sheet has been measured in accordance with a
standardised test given in EN 60745 and may be used to compare one tool with another. It may be used for a
preliminary assessment of exposure. The declared vibration emission level represents the main applications of
the tool. However if the tool is used for different applications, with different accessories or poorly maintained,
the vibration emission may differ. This may significantly increase the exposure level over the total working
period. An estimation of the level of exposure to vibration should also take into account the times when the
tool is switched off or when it is running but not actually doing the job. This may significantly reduce the
exposure level over the total working period. Identify additional safety measures to protect the operator from
the effects of vibration such as: maintain the tool and the accessories, keep the hands warm, organisation of
work patterns.

5.1 General safety warnings

WARNING! Read all instructions! Failure to follow all

instructions listed below may result in electric shock,
fire and/or serious injury. The term “power tool” in
all of the warnings listed below refers to your mains­operated (corded) power tool or battery-operated
(cordless) power tool. SAVE THESE INSTRUCTIONS.

5.1.1 Work area

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 oper-

ating 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. Unmodified 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 con-

ditions. 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 the risk of electric shock.

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.

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.

22

b) Use safety equipment. Always wear eye pro-

tection. Safety equipment such as dust mask,
non-skid safety shoes, hard hat, or hearing pro­tection used for appropriate conditions will reduce
personal injuries.

c) Avoid accidental starting. Ensure the switch is

in the off-position before plugging in. Carrying
power tools with your finger on the switch or
plugging in power tools that have the switch on
invites accidents.

d) Remove any adjusting key or wrench before

turning the power tool on. A wrench or a key left
attached 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 these

devices 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 prevent-

ive safety measures reduce the risk of starting the
power tool accidentally.

d) Store idle power tools out of the reach of children

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.

f) Keep cutting tools sharp and clean. Properly

maintained 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 and
in the manner intended for the particular type
of power tool, taking into account the working
conditions and the work to be performed. Use of

the power tool for operations different from those
intended could result in a hazardous situation.

5.1.5 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 Additional safety instructions

5.2.1 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 power tool securely with both

hands on the grips provided. Keep the grips dry,
clean and free from oil and grease.
Hold tool by insulated gripping surfaces when

d)

performing an operation where the cutting tool
may contact hidden wiring or its own cord. Con-

tact with a “live” wire will make exposed metal
parts of the tool “live” and shock the operator.

e) Breathing protection must be worn if the power

tool is used without a dust removal system for
work that creates dust.

f) Improve the blood circulation in your fingers by

relaxing your hands and exercising your fingers
during breaks between working.

g) Avoid touching rotating parts. Switch the power

tool on only after bringing it into position at
the workpiece. Touching rotating parts, especially

rotating insert tools, may lead to injury.

h) Always lead the supply cord and extension cord

away from the power tool to the rear while
working. This helps to avoid tripping over the cord

while working.

en

23

i) When using the power tool for mixing, set the

function selector switch to “Hammer drilling”
and wear protective gloves.

j) Children must be instructed not to play with the

appliance.

k) The appliance is not intended for use by chil-

dren, by debilitated persons or those who have

en

received no instruction or training.

5.2.2 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.

c) Always work from a secure, safe stance.

5.2.3 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. 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 materi­als should be checked at regular intervals at a
Hilti Service Center. Under unfavorable circum-

stances, dampness or dust adhering to the surface
of the power tool, especially dust from conductive
materials, may present a risk of electric 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

residual current device) with a maximum tripping
current of 30 mA is recommended.

5.2.4 Work area

a) Ensure that the workplace is well lit.
b) Ensure that the workplace is well ventilated.

Exposure to dust at a poorly ventilated workplace
may result in damage to the health.

c) 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 allergic reactions and/or respiratory
diseases to the operator or bystanders. Certain
kinds of dust are classified as carcinogenic such
as oak and beech dust especially in conjunction
with additives for wood conditioning (chromate,
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.

d) 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.

5.2.5 Personal protective equipment

The user and any other persons in the vicinity must
wear suitable eye protection, a hard hat, ear pro­tection, protective gloves and breathing protection
while the power tool is in use.

en

7.2.1 TPS theft protection system (optional)

NOTE

The power tool may be equipped with the optional
theft protection system. If the power tool is equipped
with this feature, it can be unlocked and made ready
for operation only through use of the corresponding
TPS key.

7.2.1.1 Unlocking the power tool 5

1. Plug the supply cord into the power outlet. The
yellow theft protection indicator LED blinks. The
power tool is now ready to receive the signal from
the TPS key.

2. Hold the TPS key against the lock symbol. The
power tool is unlocked as soon as the yellow theft
protection indicator LED no longer lights.
NOTE If, for example, the electric supply is briefly
interrupted due to a power failure or disconnected
when moving to a different workplace, the power
tool remains ready for operation for approx. 20
minutes. In the event of a longer interruption, the
TPS key must be used again to unlock the power
tool.

7.2.1.2 Activation of the theft protection system
for the power tool

NOTE

Further detailed information on activation and use
of the theft protection system can be found in the
operating instructions for the theft protection system.

7.2.2 Hammer drilling 6

NOTE

Working at low temperatures: The hammering mech­anism works only when the power tool has reached
a minimum operating temperature. Bring the tip of
the drill bit or chisel into contact with the workpiece
and allow the power tool to run under no load until
it reaches the minimum operating temperature. If ne­cessary, repeat this procedure until the hammering
mechanism begins to operate.

1. Turn the function selector switch until it engages
in the “Hammer drilling” position.

2. Bring the side handle into the desired position
and check that it is fitted correctly and secured.

3. Plug the supply cord into the power outlet.

4. Set the drilling power.
NOTE After connecting the supply cord to the
electric supply, the power tool is always set to full
drilling power.
NOTE To set the power tool to reduced (50%)
drilling power, press the “reduced power” button.
The drilling power LED then lights. To reselect full
drilling power, press the “reduced power” button
again.

5. Position the power tool and drill bit at the point
where the hole is to be drilled.

6. Press the control switch slowly (drill at a low
speed until the drill bit centers itself in the hole).

7. Press the control switch fully to continue working
at full power.

8. Do not apply excessive pressure. This will not in­crease the power tool’s hammering performance.
Lower pressure extends the life of the insert tool.

9. Reduce drilling speed shortly before breaking
through in order to avoid damage to the surface
at the rear side.

7.2.3 Active Torque Control (TE 80‑ATC/
TE 70‑ATC)

In addition to the mechanical safety clutch, the power
tool is also equipped with the Active Torque Control
system. 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 unintentionally. When the torque
control system has become activated, the power tool
can be restarted by releasing the control switch and
re-engaging it after the motor has stopped rotating
(a “click” indicates that the power tool is again ready
for operation). Always choose a working position in
which the electric tool is free to rotate in a clockwise
direction (as seen by the operator). If this rotation is
not possible, the ATC system will be unable to react.

7.2.4 Chiseling 7

NOTE

The chisel can be adjusted to 24 different positions
(in 15° increments). This ensures that flat chisels and

26

shaped chisels can always be set to the optimum

NOTE After connecting the supply cord to the
electric supply, the power tool is always set to full
chiseling power.
NOTE To set the power tool to reduced (50%)
chiseling power, press the “reduced power” but­ton. The chiseling power LED then lights. To
reselect full chiseling power, press the “reduced
power” button again.

7. Position the tip of the chisel at the point where
chiseling is to begin.

8. Press the control switch fully.

7.2.5 Drilling without hammering

Drilling without hammering is possible when drill bits
with a special connection end are used. Drill bits of
this kind are available from Hilti. For example, when
