2.2 Careful handling and use of cordless welding machines
▶ Comply with the following safety instructions for the safe handling and use of products with Li-ion
batteries. Failure to comply can lead to skin irritation, severe corrosive injury, chemical burns, fire and/or
explosion.
▶ Use only the Hilti C 53 charger to charge the welding machine. There is a risk of fire if any other charger
is used.
▶ Follow the charging instructions in these operating instructions and in the operating instructions of the
charger. Do not charge the product outside the stated temperature range. Incorrect charging or charging
at temperatures outside the defined range can damage the battery or increase the risk of fire.
▶ Make sure that the product is switched off when it is not in use. Keep the product well away from other
metallic objects such as paper-clips, coins, keys, nails and other small metallic objects that could create
a conductive bridge from one connection to the other. Short-circuiting connections can cause burns or
fires.
▶ Misuse can result in battery fluid escaping from the product. Avoid contact with this liquid. If contact
accidentally occurs, rinse with water. Seek medical attention if the liquid comes into contact with the
eyes. Liquid escaping from the battery can cause skin irritation or burns.
▶ Treat the product with care in order to avoid damage and prevent leakage of fluids that are extremely
harmful to health!
▶ Do not use a damaged or modified welding machine. Damaged or modified components and products
can exhibit unpredictable behavior that can lead to explosions or risk of injury.
▶ Do not disassemble, squash or incinerate the product and the installed battery, do not subject them to
temperatures above 80 °C (176 °F) or burn them. Fire or temperatures above 130 °C (265 °F) can lead to
an explosion.
▶ Never expose the product to the direct rays of the sun, elevated temperature, sparking, or open flame.
This can lead to explosions.
▶ If the product is too hot to touch, it may be defective. Put the product 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 product
to cool down. If the product is still too hot to touch after an hour, it 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.
