2.1 General safety instructions
WARNING Study all safety instructions and other instructions, im-
ages and technical data with which this power tool is provided. Failure
to observe the instructions below can result in electric shock, fire and/or se-
rious injury.
Keep all safety instructions and instructions for future reference.
▶Persons (including children) with reduced physical, sensory or mental
abilities or lack of experience and knowledge are not permitted to use
this product.
▶Do not allow children to play with the product.
▶Install the charger in such a way that a battery inserted into it cannot fall
out.
2.2 Battery charger use and care
▶To avoid injury, use the charger only to charge Hilti Li-ion batteries
approved for use with this charger.
▶The location at which the charger is used should be clean, cool, dry and
protected from frost.
▶The charger must be able to emit heat while in operation. The air vents
must therefore remain unobstructed. Do not operate the charger inside
a closed container.
▶Maintain the product carefully. Make sure that no parts are broken or
damaged in such a way that the product no longer functions correctly. If
parts are damaged or broken, have the product repaired prior to further
use.
▶Use chargers and the corresponding batteries in accordance with these
instructions and as is specified for this particular model. Use of chargers
for applications different from those intended could result in hazardous
situations.
▶Recharge the batteries only with the chargers specified by the manufac-
turer. A charger that is suitable for a certain type of battery may present
a risk of fire when used with other types of battery.

4 English 2275225 *2275225*
▶When not in use, keep the battery and the charger away from paper
clips, coins, keys, nails, screws or other small metal objects that could
cause a short circuit at the battery terminals or the charging contacts.
A short circuit between the battery terminals or charging contacts may
cause injuries (burns) and result in fire.
▶Do not store the battery on the charger. Always remove the battery from
the charger when the charging operation has completed.
2.3 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 tempera-
ture, 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.

*2275225* 2275225 English 5
▶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.
