SF 2H­A12
Safety instructions for all operations
▶ Wear ear protectors when impact drilling. Exposure to noise can cause hearing loss.
▶ Hold the power tool by insulated gripping surfaces, when performing an operation where
the cutting accessory or fasteners may contact hidden wiring. Cutting accessory or fasteners
contacting a "live" wire may make exposed metal parts of the power tool "live" and could give the
operator an electric shock.
Safety instructions when using long drill bits
▶ Never operate at higher speed than the maximum speed rating of the drill bit. At higher speeds,
the bit is likely to bend if allowed to rotate freely without contacting the workpiece, resulting in personal
injury.
▶ Always start drilling at low speed and with the bit tip in contact with the workpiece. At higher
speeds, the bit is likely to bend if allowed to rotate freely without contacting the workpiece, resulting in
personal injury.
▶ Apply pressure only in direct line with the bit and do not apply excessive pressure. Bits can bend
causing breakage or loss of control, resulting in personal injury.
2.3 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, direct sunlight or fire.
▶ Do not disassemble, crush or incinerate batteries and do not subject them to temperatures over 80 °C
(176 °F).
▶ 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. Put the battery in a place where it is clearly visible
and where there is no risk of fire, at an adequate distance from flammable materials. Allow the battery to
cool down. If it is still too hot to touch after an hour, the battery is faulty. Contact Hilti Service.

Additional safety instructions

Personal safety
▶ Use the product only when it is in perfect working order.
▶ Never tamper with or modify the tool in any way.
▶ Do not look directly into the light source (LEDs) integrated in the drill/driver and do not direct the light at
other persons' faces. This presents a risk of dazzling or eye damage.
▶ 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.
▶ Wear protective gloves also when changing the accessory tool. Touching the accessory tool presents a
risk of injury (cuts or burns).
▶ Always hold the tool securely by the grip. If the accessory tool (e.g. the drill bit) sticks and stalls, the
power tool, due to its high torque, may tend to rotate about its own axis in the direction opposite to that
of the accessory tool.
▶ 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 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.
▶ Take breaks and exercise your fingers to improve the blood circulation. 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 beginning work, check the working area for concealed electric cables or gas and water pipes.
External metal parts of the power tool may give you an electric shock if you damage an electric cable
accidentally.
Power tool use and care
▶ 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.
▶ Immediately switch off the power tool if the accessory tool jams. The power tool might twist off-line.
