▶Take frequent breaks and do physical exercises to improve the blood circulation in your fingers. High
vibration during long periods of work can lead to disorders of the blood vessels and nervous system in
the fingers, hands and wrists.
▶Do not touch rotating parts. Switch the product on only after it is in position at the workpiece. Touching
rotating parts, especially rotating accessory tools, can result in injury.
▶Activate the switch-on interlock (forward/reverse switch in the middle position) for storing or transporting
the product.
▶The product is not intended for use by debilitated persons who have received no special training. Keep
the product out of reach of children.
▶If the work involves breaking right through, take the appropriate safety measures on the opposite side.
Parts breaking away could fall out and / or fall down and injure other persons.
▶Before beginning work, check the working area for concealed electric cables or gas and water pipes.
External metal parts of the product could give you an electric shock or cause an explosion if you
accidentally damage an electric cable or a gas or water pipe.
▶In accordance with the applications for which it is designed, the product produces a high torque. Always
use the side handle and hold the product with both hands. The user must be prepared for sudden
sticking and stalling of the accessory tool.
▶Secure the workpiece. Use clamps or a vice to secure the workpiece. The workpiece is thus held more
securely than by hand and in addition, both hands remain free to operate the product.
▶Wear protective gloves. The product can get hot during operation. There is a risk of injury (cutting or
burning) if the accessory tool is touched while changing it.
▶Keep the air vents clear at all times. Risk of burn injuries due to blocked air vents!
▶Working on the material may cause it to splinter. Wear eye protection, protective gloves and, if you are
not using a dust removal system, wear light respiratory protection. Flying fragments present a risk of
injury to the eyes and body.
▶Risk of injury by falling tools and/or accessories. Before starting work, check that installed accessories
are secure.
▶Do not attach a belt hook to this product.
2.4 Careful handling and use of batteries
▶Comply with the following safety instructions for the safe handling and use of Li-ion batteries.
Failure to comply can lead to skin irritation, severe corrosive injury, chemical burns, fire and/or explosion.
▶Use only batteries that are in perfect working order.
▶Treat batteries with care in order to avoid damage and prevent leakage of fluids that are extremely
harmful to health!
▶Do not under any circumstances modify or tamper with batteries!
▶Do not disassemble, crush or incinerate batteries and do not subject them to temperatures over 80 °C
(176 °F).
▶Never use or charge a battery that has suffered an impact or been damaged in any other way. Check
your batteries regularly for signs of damage.
▶Never use recycled or repaired batteries.
▶Never use the battery or a battery-operated power tool as a striking tool.
▶Never expose batteries to the direct rays of the sun, elevated temperature, sparking, or open flame. This
can lead to explosions.
▶Do not touch the battery poles with your fingers, tools, jewelry, or other electrically conductive objects.
This can damage the battery and also cause material damage and personal injury.
▶Keep batteries away from rain, moisture and liquids. Penetrating moisture can cause short circuits,
electric shock, burns, fire and explosions.
▶Use only chargers and power tools approved for the specific battery type. Read and follow the relevant
operating instructions.
▶Do not use or store the battery in explosive environments.
▶If the battery is too hot to touch, it may be defective. Put the battery in a place where it is clearly visible
and where there is no risk of fire, at an adequate distance from flammable materials. Allow the battery to
cool down. If it is still too hot to touch after an hour, the battery is faulty. Consult Hilti Service or read the
document entitled "Instructions on safety and use for Hilti Li-ion batteries".
Observe the special guidelines applicable to the transport, storage and use of lithium-ion batteries.
