Hilti TE 2-A22 Original Operating Instructions page 9

▶ 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, such as oak and beech dust, are classified as carcinogenic, 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. Observe national
regulations applicable to the materials you intend to work with.
▶ 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 (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, if an electric cable is damaged accidentally. This presents a serious risk
of electric shock.
▶ In accordance with the applications for which it is designed, the tool produces a high torque. Always
use the side handle and hold the tool with both hands. The user must be prepared for sudden sticking
and stalling of the cutting tool.
▶ Secure the workpiece. Use clamps or a vice to secure the workpiece. The workpiece is thus held
more securely than by hand and both hands remain free to operate the tool.
▶ 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.
Use and care of electric tools
▶ Do not operate the function selector switch or the forward/reverse switch while the motor is
running. There is a risk of the gearing becoming damaged.
Careful handling and use of batteries
▶ Observe the special guidelines applicable to the transport, storage and use of lithium-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.
▶ Avoid ingress of moisture. Ingress of moisture may cause a short circuit, resulting in burning injuries or
fire.
▶ Do not disassemble, squash or incinerate batteries and do not subject 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).
▶ 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.
