▶
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.
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.
▶
Wait until the power tool stops completely before you lay it down.
