Drill safety warnings

Safety instructions for all operations
▶ Use the auxiliary handle(s). Loss of control can cause personal injury.
▶ Hold the power tool by insulated gripping surfaces, when performing an operation where the
cutting accessory may contact hidden wiring or its own cord. Cutting accessory 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.

Additional safety instructions

Personal safety
▶ Use the product and accessories only when they are in perfect working order.
▶ Never tamper with or modify the product or accessories in any way.
▶ During hand-held use, always hold the machine securely with both hands on the grips provided. Keep
the grips dry, clean and free from oil and grease.
▶ Respiratory protection must be worn if the machine is used without a dust extraction system for work
that creates dust.
▶ Take frequent breaks and do physical exercises to improve the blood circulation in your fingers. High
vibration during long periods of work can lead to disorders of the blood vessels and nervous system in
the fingers, hands and wrists.
▶ Avoid touching rotating parts. Switch the power tool on only after bringing it into position at the
workpiece. Touching rotating parts, especially rotating drill bits, discs or blades, etc. may lead to injury.
▶ When working, always lead the supply cord, the extension cord and the vacuum cleaner hose (if
applicable) away from the machine to the rear. This will reduce the risk of tripping and falling over the
cord or hose while working.
▶ Avoid skin contact with drilling slurry.
▶ Wear protective gloves when changing the accessory tool. The accessory tool can become hot in use.
▶ Children are not permitted to play with the machine and must be instructed accordingly.
▶ The power tool is not intended for use by children, by debilitated persons or those who have received no
instruction or training.
▶ Dust from materials such as paint containing lead, some types of wood, minerals and metal can be
harmful to health. Contact with or inhalation of the dust can cause allergic reactions and/or respiratory
or other diseases to the operator or bystanders. Certain kinds of dust such as oakwood and beechwood
dust are classified as carcinogenic, especially in conjunction with additives for wood conditioning
(chromate, wood preservative). Only specialists are permitted to work on material containing asbestos.
Use a dust-extraction device wherever possible. To achieve a high level of dust extraction, use a suitable
mobile dust extractor of a type that is recommended by Hilti for wood dust and/or mineral dust and
which is designed for use with this power tool. Make sure that the workplace is well ventilated. It is
advisable to wear a filter class P2 dust mask. Comply with national regulations applicable to the materials
you will be working with.
▶ The user and persons in the vicinity must wear suitable protective goggles, a hard hat, ear defenders,
protective gloves, protective footwear and light respiratory protection while the tool is in use.
Power tool use and care
▶ 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 machine.
