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.

them to temperatures over 80°C (176°F). This presents a risk of fire,
explosion or injury through contact with caustic substances.
▶ Never continue to use or attempt to charge damaged batteries, e.g.
batteries with cracks, broken parts, bent or pushed-in / pulled-out
contacts).

tools or appliances.
▶ If the battery is too hot to hold, 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.
