6 Safety instructions
6.1 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.
6.1.1Workareasafety
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.
6.1.2 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.
6.1.3 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.
6.1.4 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.

Printed: 08.07.2013 | Doc-Nr: PUB / 5070549 / 000 / 02

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.
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.
6.1.5 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.
6.1.6 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.
6.2 Additional safety rules
6.2.1 Personal safety
a) Hold power tool by insulated gripping surfaces,
when performing an operation where the fastener
may contact hidden wiring. Fasteners contacting
a "live" wire may make exposed metal parts of the
power tool "live" and could give the operator an
electric shock.
b) It is recommended that ear protectors are worn.
Exposure to noise can cause hearing loss.
c) Keep the power tool, especially its grip surfaces,
clean and free from oil and grease. Do not use
cleaning agents which contain silicone.
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) Use the right power tool for the job. Do not use
the power tool for purposes for which it was not
intended. Use it only as directed and when in
faultless condition.
h) Avoid unintentional starting. Never carry the
power tool with your finger on the on/off switch.
Remove the battery from the power tool during
work breaks, before carrying out maintenance,
before changing cutting tools and before
transporting the power tool.
i) Check that the belt hook is fitted securely before
beginning work.
j) Do not carry the tool by the depth gauge.The depth
gauge may pull off unexpectedly.
k) Children must be instructed not to play with the
power tool.
l) The power tool is not intended for use by children,
by debilitated persons or those who have received
no instruction or training.
m) 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.
n) Check that the power tool is placed in a secure
position when it is laid down, especially when
used with the magazine and / or extension.

6.2.2 Power tool use and care
Checkthattheinserttoolsusedarecompatiblewith
the chuck system and that they are secured in the
chuck correctly.
6.2.3 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.
6.2.4 Battery tool use and care
a) Do not expose batteries to high temperatures or
fire. This presents a risk of explosion.
b) Do not disassemble, squash or incinerate batter-
ies and do not subject them to temperatures over
80°C. A risk of fire, explosion or injury through con-
tact with caustic substances may otherwise result.
c) 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.
d) Observe the special instructions applicable to the
transport, storage and use of Li-ion batteries.
e) 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.
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) 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
allowedtocool.
6.2.5 Work area
Ensure that the workplace is well ventilated. Exposure
to dust at a poorly ventilated workplace may result in
damage to the health.

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.
9.3 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.
9.4 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.
9.5 Checking the power tool after care and
maintenance
After carrying out care and maintenance work on the
power tool, check that all protective and safety devices
are fitted and that they function faultlessly.

11 Disposal
CAUTION
Improper disposal of the equipment may have serious consequences: the burning of plastic components generates
toxic fumes which may present a health hazard. Batteries may explode if damaged or exposed to very high
temperatures, causing poisoning, burns, acid burns or environmental pollution. Careless disposal may permit
unauthorized and improper use of the equipment. This may result in serious personal injury, injury to third parties and
pollution of the environment.
CAUTION
Dispose of defective batteries without delay. Keep them out of reach of children. Do not attempt to open or dismantle
batteries and do not dispose of them by incineration.
CAUTION
Dispose of the batteries in accordance with national regulations or return them to Hilti.
Most of the materials from which Hilti power tools or appliances are manufactured can be recycled. The materials
must be correctly separated before they can be recycled. In many countries, Hilti has already made arrangements for
taking back your old power tools or appliances for recycling. Please ask your Hilti customer service department or
