Careful handling and use of batteries
▶
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".
Observe the special guidelines applicable to the transport, storage and use of lithium-ion
batteries.
