▶
Wear a dust mask if the tool is operated without a dust removal system.
▶
Improve the blood circulation in your fingers by relaxing your hands and exercising your fingers during
breaks between working. 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.
▶
The power tool is not intended for use by debilitated persons who have received no special training.
Keep the power tool out of reach of children.
▶
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.
▶
Wear protective gloves. The drill / driver may get hot during use. There is a risk of injury (cutting or
burning) if the accessory tool is touched while changing it.
▶
Activate the safety lock (forward/reverse selector switch in the middle position) when changing accessory
tools or batteries and before storage or transportation of the power tool.
▶
Use a dust removal system and suitable vacuum cleaner whenever possible. Dust from materials, such
as paint containing lead, some kinds of wood, concrete / masonry / stone containing silica, and minerals
as well as metal, may be injurious 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 to the operator or bystanders. Certain kinds of dust such as oak and beech
wood dust are classified as carcinogenic, especially in conjunction with additives for wood conditioning
(chromate, wood preservative). Material containing asbestos may be worked on only by specialists.
▶
Before beginning the work, check the hazard classification of the dust that will be produced. Use an
industrial vacuum cleaner with an officially approved protection classification in compliance with locally
applicable dust protection regulations.
▶
Wear eye protection. Flying fragments present a risk of injury to the body and eyes.
▶
The user and any other persons in the vicinity must wear suitable eye protection, a hard hat, ear
protection, protective gloves and breathing protection while the power tool is in use.
Use and care of electric tools
▶
Secure the workpiece. A workpiece clamped in a vice or secured by some other clamping device is more
secure than when held only by hand.
▶
Check that the accessory tools used are compatible with the chuck system and that they are secured in
the chuck correctly.
▶
Use large, heavy accessory tools only with the power tool set to first gear. There is otherwise a risk of
causing damage to the power when switching it off or, under unfavorable circumstances, the chuck may
work loose.
▶
Wait until the power tool stops completely before you lay it down.
Careful handling and use of Li-ion batteries
▶
Observe the special guidelines applicable to the transport, storage and use of Li-ion batteries.
▶
Check that the product is switched off before fitting the battery.
▶
Do not expose batteries to high temperatures, direct sunlight or fire.
▶
Do not disassemble, squash or incinerate batteries and do not subject them to temperatures over 80°C
(176°F).
▶
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.
▶
Avoid short circuiting the battery terminals. Check that the battery terminals and the terminals in the
power tool are free from foreign objects before inserting the battery in the tool.
Electrical safety
▶
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, when an electric cable is damaged accidentally. This presents a serious risk of electric
shock.
