Safety
2.1 General power tool safety warnings
WARNING
Read all safety warnings and all 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.
Work area safety
▶ Keep work area clean and well lit. Cluttered or dark areas invite accidents.
▶ Do not operate power tools in explosive atmospheres, such as in the presence
of flammable liquids, gases or dust. Power tools create sparks which may
ignite the dust or fumes.
▶ Keep children and bystanders away while operating a power tool. Distractions
can cause you to lose control.
Electrical safety
▶ 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.
▶ 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.
▶ Do not expose power tools to rain or wet conditions. Water entering a power
tool will increase the risk of electric shock.
▶ 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.
▶ 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.
▶ 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.
Personal safety
▶ 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.
▶ 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.
▶ Prevent unintentional starting. Ensure the switch is in the off‐position
before connecting to power source, 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.
▶ 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.
▶ Do not overreach. Keep proper footing and balance at all times. This enables
better control of the power tool in unexpected situations.
▶ 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.
▶ 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.
Power tool use and care
▶ 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.
▶ 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.
▶ Disconnect the plug from the power source 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.
▶ 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.
▶ 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.
▶ Keep cutting tools sharp and clean. Properly maintained cutting tools with
sharp cutting edges are less likely to bind and are easier to control.
▶ 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.
2.2 Battery charger use and care
▶ To avoid injury, use the charger only to charge Hilti Li-ion batteries
approved for use with this charger.
▶ The location at which the charger is used should be clean and cool but
protected from frost.
▶ The charger must be able to emit heat while in operation. The air vents must
therefore remain unobstructed. Accordingly, remove the charger from the
toolbox. Do not operate the charger inside a closed container.
▶ Maintain the appliance carefully. Check to ensure that no parts are broken
or damaged in such a way that the appliance may no longer function correctly.
If parts are damaged, have the parts repaired before using the appliance.
▶ Use chargers and the corresponding batteries in accordance with these
instructions and as is specified for this particular model. Use of chargers
for applications different from those intended could result in hazardous
situations.
▶ Recharge the batteries only with the chargers specified by the manufacturer.
A charger that is suitable for a certain type of battery may present a risk of
fire when used with other types of battery.
▶ When not in use, keep the battery and the charger away from paper clips,
coins, keys, nails, screws or other small metal objects that could cause a
short circuit at the battery terminals or the charging contacts. A short
circuit between the battery terminals or charging contacts may cause injuries
(burns) and result in fire.
▶ Under abusive conditions, liquid may be ejected from the battery. Avoid
contact with the liquid. If contact accidentally occurs, flush with water. If
the liquid contacts the eyes, also seek medical attention. Liquid leaking from
the battery may cause irritation or burns.
▶ Make sure that the batteries suffer no mechanical damage.
▶ Do not charge or continue to use damaged batteries (e.g. batteries with
cracks, broken parts, bent or pushed-in and/or pulled-out contacts).
2.3 Battery use and care
▶ Observe the special regulations and instructions applicable to the
transport, storage and use of Li-ion batteries.
▶ Do not expose batteries to high temperatures, direct sunlight or fire.
▶ Do not disassemble, crush or incinerate batteries and do not subject them to
temperatures over 80 °C.
▶ Do not use or charge batteries that have suffered mechanical impact, have
been dropped from a height or show signs of damage. In this case, always
contact your Hilti Service.
▶ If the battery is too hot to touch it may be defective. In this case, place
the product in a non-flammable location, well away from flammable materials,
where it can be kept under observation and allowed to cool down. In this case,
always contact your Hilti Service.

Disposal
WARNING
Risk of injury. Hazards presented by improper disposal.
▶ Improper disposal of the equipment may have the following 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.
▶ Dispose of defective batteries right away. Keep them out of reach of
children. Do not disassemble or incinerate the batteries.
▶ Batteries that have reached the end of their life must be disposed of in
accordance with national regulations or returned to Hilti.
Most of the materials from which Hilti tools and appliances are manu-factured
can be recycled. The materials must be correctly separated before they can be
recycled. In many countries, your old tools, machines or appliances can be
returned to Hilti for recycling. Ask Hilti Service or your Hilti
representative for further information.
In accordance with the European Directive on waste electrical and electronic
appliances and its implementation in conformance with national law, electrical
and electronic appliances that have reached the end of their life must be
collected separately and returned to an environmentally compatible recycling
facility.
