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, require to 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. Fail-
ure 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.
5.1.1 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.
b) Avoid body contact with earthed or grounded
surfaces such as pipes, radiators, ranges and refrigerators. Thereisan 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.
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 offposition 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.
e)
Do not overreach. Keep proper footing and bal­ance 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 frommoving 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 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.
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 accordancewiththeseinstructions 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 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 ac­cidentally 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 Additional safety instructions
5.2.1 Personal safety
a) Hold power tool by insulated gripping surfaces,
when performing an operation where the fas­tener may contact hidden wiring. Fasteners con-
tacting a "live" wiremaymakeexposed metal parts of the power tool "live" and could give the operator an electric shock.
b) Wear ear protectors. Exposuretonoise can cause
hearing loss.
c) Use auxiliary handle(s), if supplied with the
tool. Loss of control can cause personal injury.
d) Always hold the power tool securely with both
hands on the grips provided. Keep the grips dry, clean and free from oil and grease.
e) Improve the blood circulation in your fingers by
relaxing your hands and exercising your fingers during breaks between working.
f) 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.

Some examples of these chemicals are: lead from lead-based paints, crystalline silica from bricks, concrete and other masonry products and natural stone, arsenic and chromium from chemically­treated 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 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 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.
5.2.2 Electric 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.
5.2.3 Battery tool use and care
a) Ensure the switch is in the off position before
inserting the battery pack. Inserting the battery
pack into a lamp that is switched on may dazzle you.
b) Do not expose batteries to high temperatures or
fire. This presents a risk of explosion.
c) 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.
d) Avoid ingress of dampness.Dampness may
cause a short circuit resulting in a risk of burning injury or fire.
e) Do not use batteries other than those approved
for use with the applicable power tool or appli­ance. 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) Observe the special instructions applicable to
the transport, storage and use of Li-ion batter­ies.
g) Remove the battery before storing or transport-
ing the power tool.
h) 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.
i) 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).
j) If the battery gets too hot to touch, this may indi-
cate that it is faulty. Place the tool at a location
where there is no riskofcausinga fire (at least 3 meters away from flammable materials), where it can be kept under observation and allowed to cool. Contact Hilti Service after the battery has been allowed to cool.
5.2.4 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.
5.2.5 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.
5.2.6 Personal protective equipment

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 Hilti representative for further information.
