screwdriving, the grip of the power tool may be deflected laterally (the power tool tends to pivot about its
own axis).
▶ Avoid touching rotating parts. Switch the power tool on only after bringing it into position at the
workpiece. Touching rotating parts, especially rotating accessory tools, may lead to injury.
▶ Activate the safety lock (forward/reverse selector switch in the middle position) when changing
accessory tools or batteries and before storage or transportation of the power tool.
▶ Wear protective gloves. The drill/driver may get hot during use. There is a risk of injury (cutting or
burning) if the accessory tool is touched while changing it.
▶ The user and any other persons in the vicinity must wear suitable eye protection, a hard hat, ear
protection, protective gloves and breathing protection while the power tool is in use.
▶ Improve the blood circulation in your fingers by relaxing your hands and exercising your fingers
during breaks between 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.
▶ Before beginning the work, check the hazard classification of the dust that will be produced. Use
an industrial vacuum cleaner with an officially approved protection classification in compliance
with locally applicable dust protection regulations.
▶ Working on the material may cause it to splinter. Wear eye protection. Flying fragments present a risk
of injury to the body and eyes.
▶ 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.
▶ Observe the national health and safety requirements.
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.
Use and care of electric tools
▶ 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.
▶ Check that the accessory tools used are compatible with the chuck system and that they are
secured in the chuck correctly.
▶ 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 when switching it off or, under unfavorable circumstances, the chuck
may work loose.
Careful handling and use of batteries
▶ Do not use the battery as a power source for other unspecified appliances.
▶ Observe the special guidelines applicable to the transport, storage and use of Li-ion batteries.
▶ Do not expose batteries to high temperatures, the direct heat of the sun, and keep them away
from fire. There is a risk of explosion.
▶ Do not disassemble, squash or incinerate batteries and do not subject them to temperatures over
80°C. This presents a risk of fire, explosion or injury through contact with caustic substances.
▶ Do not continue to use or attempt to charge damaged batteries (e.g. batteries with cracks, broken
parts, bent or pushed-in / pulled-out contacts).
▶ If the battery is too hot to touch it may be defective. In this case, place the power tool in a non-
flammable location, well away from flammable materials, where it can be kept under observation
and allowed to cool down. Contact Hilti Service after the battery has cooled down.
