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
