5.1 General power tool safety warnings
a)
WARNING
5.1.3 Personal safety
Read all safety warnings and instructions. Fail-
en
ure to follow the warnings and instructions may a) Stay alert, watch what you are doing and use
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.
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 offಣposition 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
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.
5.1.1 Work area safety
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.
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.
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.
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.
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
5
c) Disconnect the plug from the power source
and/or the battery pack from the power tool
before making any adjustments, changing ac-
cessories, or storing power tools. Such preven-
tive 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.
parts. This will ensure that the safety of the power
tool is maintained.
5.2 Additional safety precautions
5.2.1 Personal safety
en
a) Hold power tool by insulated gripping surfaces,
when performing an operation where the fas-
tener may contact hidden wiring. Fasteners con-
tacting a "live" wire may make exposed metal parts
of the power tool "live" and could give the operator
an electric shock.
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 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.
b) It is recommended that ear protectors are worn.
Exposure to noise can cause hearing loss.
c) Keep the power tool, especially its grip sur-
faces, 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
rotating 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 trans-
porting the power tool.
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 desig-
nated 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 termi-
nals together may cause burns or a fire.
d) Under abusive conditions, liquid may be ejected
from the battery, avoid contact. If contact ac-
cidentally occurs, flush with water. If liquid
contacts eyes, additionally seek medical help.
Liquid ejected from the battery may cause irrita-
tion or burns.
i) Do not carry the tool by the depth gauge or by
the guard.The snap-on connection may uninten-
tionally become undone.
j) Children must be instructed not to play with the
power tool.
k) The power tool is not intended for use by chil-
dren, by debilitated persons or those who have
received no instruction or training.
l) WARNING: Some dust created by grinding,
sanding, cutting and drilling contains chem-
icals known to cause cancer, birth defects,
infertility or other reproductive harm; or seri-
ous and permanent respiratory or other injury.
Some examples of these chemicals are: lead from
5.1.6 Service
a) Have your power tool serviced by a qualified
repair person using only identical replacement
6
lead-based paints, crystalline 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 approved safety
equipment, such as respiratory protection ap-
propriate 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 protective
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
absorption of harmful chemicals.
5.2.4 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 bat-
teries and do not subject them to temperatures
over 80°C. A risk of fire, explosion or injury
through contact 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 batter-
ies.
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
battery terminals presents a risk of fire, explosion
and chemical burns.
en
m) Do not lift or carry the tool by the accessories
attached to it.
5.2.2 Careful use of the power tool
Check that the insert tools used are compatible with
the chuck system and that they are secured in the
chuck correctly.
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).
5.2.3 Electrical safety
5.2.5 Work area safety
Ensure that the workplace is well ventilated. Ex-
posure to dust at a poorly ventilated workplace may
result in damage to the health.
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.
5.2.6 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 while the power
tool is in use.
7
6. Before use

8. Care and maintenance
CAUTION
NOTE
Before beginning cleaning, remove the battery from
the power tool in order to prevent unintentional
starting.
If use of the power tool continues, further battery
discharge will be stopped automatically before the
battery cells suffer damage.
en
8.1 Care of insert tools
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.
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.
- Interruption of the charging procedure has no neg-
ative 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).
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
cleaning agents which contain silicone.
- 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.
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.
8.4 Maintenance
WARNING
Repairs to the electrical section of the power tool
may be carried out only by trained electrical spe-
cialists.
Dirt or foreign matter may collect in the chuck. Clean
it at regular intervals.
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.
