2 Safety
2.1 General power tool safety warnings
WARNING Read all safety warnings, instructions, illustrations and specifications provided with this
power tool. Failure to follow all instructions listed below 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.
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.
*2059547* 2059547 English 3
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 a
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 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.
▶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 and clothing 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.
▶Do not let familiarity gained from frequent use of tools allow you to become complacent and ignore
tool safety principles. A careless action can cause severe injury within a fraction of a second.
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 and/or remove the battery pack, if detachable, 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 and accessories. 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.
▶Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles and
grasping surfaces do not allow for safe handling and control of the tool in unexpected situations.

Service
▶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.
2.2 Hammer safety warnings
Safety instructions for all operations
▶Wear ear protectors. Exposure to noise can cause hearing loss.
▶Use auxiliary handle(s), if supplied with the tool. Loss of control can cause personal injury.
▶Hold the power tool by insulated gripping surfaces, when performing an operation where the
cutting accessory may contact hidden wiring or its own cord. Cutting accessory contacting a "live"
wire may make exposed metal parts of the power tool "live" and could give the operator an electric
shock.
Safety instructions when using long drill bits with rotary hammers
▶Always start drilling at low speed and with the bit tip in contact with the workpiece. At higher
speeds, the bit is likely to bend if allowed to rotate freely without contacting the workpiece, resulting in
personal injury.
▶Apply pressure only in direct line with the bit and do not apply excessive pressure. Bits can bend
causing breakage or loss of control, resulting in personal injury.
2.3 Additional safety instructions
Personal safety
▶Modification of the tool is not permitted.
▶Keep the grips dry, clean and free from oil and grease.
▶Check that the side handle is fitted correctly and tightened securely.
▶Improve the blood circulation in your fingers by relaxing your hands and exercising your fingers
during breaks between working.
▶The power tool is not intended for use by debilitated persons who have received no special training.
▶Keep the power tool out of reach of children.
▶Avoid touching rotating parts. Switch the power tool on only after bringing it into position at the
workpiece. Touching rotating parts, especially rotating drill bits or other accessories, may lead to injury.
▶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.
▶Dust from materials, such as paint containing lead, some wood species, concrete / masonry / stone
containing silica, and minerals as well as metal, may be harmful. Contact with or inhalation of the dust
may cause allergic reactions and/or respiratory or other 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 may be
handled only by specialists. Use a dust removal system whenever possible. To achieve a high level
of dust collection, use a suitable vacuum cleaner. When indicated, wear a respirator appropriate
for the type of dust generated. Ensure that the workplace is well ventilated. Follow national
requirements for the materials you want to work with.
▶In the event of a power failure or interruption in the electric supply, switch the power tool off,
unplug the supply cord and release the switch lockbutton (if applicable). This will prevent accidental
restarting when the electric power returns.
▶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.
▶Observe the nationally applicable industrial safety regulations.
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 tool may
become live, for example, when an electric power line is damaged accidentally. This presents a serious
risk of electric shock.
▶Check the power tool’s supply cord at regular intervals and have it replaced by a qualified specialist
if found to be damaged. If the power tool’s supply cord is damaged it must be replaced with
a specially-prepared and approved supply cord available from Hilti Customer Service. 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.
