▶
Dust produced by grinding, sanding, cutting and drilling can contain dangerous chemicals. Some
examples are: lead or lead-based paints; brick, concrete and other masonry products, natural stone
and other products containing silicates; certain types of wood, such as oak, beech and chemically
treated wood; asbestos or materials that contain asbestos. Determine the exposure of the operator and
bystanders by means of the hazard classification of the materials to be worked. Implement the necessary
measures to restrict exposure to a safe level, for example by the use of a dust collection system or by
the wearing of suitable respiratory protection. The general measures for reducing exposure include:
▶
working in an area that is well ventilated,
▶
avoidance of prolonged contact with dust,
▶
directing dust away from the face and body,
▶
wearing protective clothing and washing exposed areas of the skin with water and soap.
▶
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.
▶
Do not look directly into the light source (LED) of the product and do not aim the beam at other persons’
faces. Risk of dazzling or eye damage.
▶
Do not activate the product until after you have brought it into position at the workpiece.
▶
Risk of injury by falling tools and/or accessories. Before starting work, check that the battery and installed
accessories are secure.
▶
Switch the product off immediately if the accessory tool jams. The product might twist off-line.
▶
Wait until the product has come to a complete stop before you lay it down.
2.4 Battery use and care
▶
Comply with the following safety instructions for the safe handling and use of Li-ion batteries.
Failure to comply can lead to skin irritation, severe corrosive injury, chemical burns, fire and/or explosion.
▶
Use only batteries that are in perfect working order.
▶
Treat batteries with care in order to avoid damage and prevent leakage of fluids that are extremely
harmful to health!
▶
Do not under any circumstances modify or tamper with batteries!
▶
Do not disassemble, crush or incinerate batteries and do not subject them to temperatures over 80 °C
(176 °F).
▶
Never use or charge a battery that has suffered an impact or been damaged in any other way. Check
your batteries regularly for signs of damage.
▶
Never use recycled or repaired batteries.
▶
Never use the battery or a battery-operated power tool as a striking tool.
▶
Never expose batteries to the direct rays of the sun, elevated temperature, sparking, or open flame. This
can lead to explosions.
▶
Do not touch the battery poles with your fingers, tools, jewelry, or other electrically conductive objects.
This can damage the battery and also cause material damage and personal injury.
▶
Keep batteries away from rain, moisture and liquids. Penetrating moisture can cause short circuits,
electric shock, burns, fire and explosions.
▶
Use only chargers and power tools approved for the specific battery type. Read and follow the relevant
operating instructions.
▶
Do not use or store the battery in explosive environments.
▶
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. Consult Hilti Service or read the
document entitled "Instructions on safety and use for Hilti Li-ion batteries".
