Hilti SF 6-A22 Original Operating Instructions page 9

▶ Wear protective gloves also when changing the accessory tool. Touching the accessory tool presents a
risk of injury (cuts or burns).
▶ Wear eye protection. Flying fragments present a risk of injury to the body and eyes.
▶ Before starting work, check the hazard class of the dust that will be produced when working. Use
an industrial vacuum cleaner with an officially approved protection class in compliance with the locally
applicable dust protection regulations. 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 working area is well ventilated and, where necessary, wear a respirator appropriate
for the type of dust generated. Contact with or inhalation of 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 treating wood (chromate,
wood preservative). Materials containing asbestos may only be handled by specialists.
▶ Take breaks between working and do physical exercises to improve the blood circulation in your fingers.
Exposure to vibration during long periods of work can lead to disorders of the blood vessels and nervous
system in the fingers, hands and wrists.
Electrical safety
▶ Before starting work, check the working area for concealed electric cables or gas and water pipes. If
you damage an electric cable accidentally, external metal parts of the power tool may become live and
present a risk of electric shock.
Careful handling and use of power tools
▶ Switch the power tool off immediately if the accessory tool jams. The power tool may go off course and
veer to the side.
▶ Wait until the power tool has come to a complete stop before setting it down.
2.5 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 use or charge batteries that have suffered mechanical impact, have been dropped from a height
or show signs of damage. In this case, always contact your Hilti Service.
▶ If the battery is too hot to touch it may be defective. In this case, place the product in a non-flammable
location, well away from flammable materials, where it can be kept under observation and allowed to
cool down. In this case, always contact your Hilti Service.
