▶ Risk of injury by falling tools and/or accessories. Before starting work, check that the battery and installed
accessories are secure.
▶ Do not use blunted bits.
▶ Use large, heavy accessory tools only with the power tool set to first gear. There is otherwise a risk of
causing damage to the power tool when switching it off or, under unfavorable circumstances, the chuck
may work loose.
▶ Use auxiliary handles supplied with the product. Loss of control can cause personal injury. Make sure
that the auxiliary handle is firmly seated and securely installed.
▶ Switch the product on only after you have brought it to the working position.
▶ Secure the workpiece. Use clamps or a vice to hold the workpiece in position. The workpiece is thus
held more securely than by hand and both hands remain free to operate the power tool.
▶ Always hold the product with both hands on the grips provided. Keep the grips clean and dry.
▶ Keep the air vents clear at all times. Risk of burn injuries due to blocked air vents!
▶ Do not touch rotating parts – risk of injury!
▶ Wear eye protection, a hard hat and ear protection and suitable respiratory protection while the product
is in use.
▶ Wear eye protection. Flying fragments can injure the body and eyes.
▶ Do not look directly into the light source (LED) of the product and do not aim the beam at other persons'
faces. Risk of dazzling or eye damage.
▶ 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.
▶ Wait until the product has come to a complete stop before you lay it down.
▶ Wear protective gloves when changing the accessory tool. Touching the accessory tool can result in
cuts and burns.
2.4 Battery use and care
▶ 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.
