Hilti TE 40 Manual page 6

▶ Use a dust removal system and suitable mobile dust extractor whenever possible. Dust from materials
such as lead-based paint, certain types of wood and concrete/masonry/stone containing quartz, minerals
or metal may be harmful to health.
▶ Make sure that the workplace is well ventilated and, where necessary, wear a respirator appropriate for
the type of dust generated. Contact with or inhalation of the dust may cause allergic reactions and/or
respiratory or other diseases among operators 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.
Electrical safety
▶ Before beginning work, check the working area for concealed electric cables or gas and water pipes.
External metal parts of the power tool can become live, presenting a risk of electric shock, if you
accidentally damage an electric cable.
Power tool use and care
▶ Secure the workpiece. A workpiece clamped in a vice or secured by some other clamping devices is
more secure than when held only by hand.
▶ Immediately switch off the power tool if the accessory tool jams. The power tool might twist off-line.
▶ Wait until the power tool stops completely before you lay it down.
Battery use and care
▶ Observe the special regulations and instructions applicable to the transport, storage and use of Li-ion
batteries.
▶ Do not expose batteries to high temperatures, direct sunlight or fire.
▶ Do not disassemble, crush or incinerate batteries and do not subject them to temperatures over 80 °C.
▶ Do not attempt to charge or continue to use damaged batteries.
▶ 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.
