10. Disposal
CAUTION
Improper disposal of the equipment may have serious consequences: The burning of plastic components
generates toxic fumes which may present a health hazard. Batteries may explode if damaged or exposed to
very high temperatures, causing poisoning, burns, acid burns or environmental pollution. Careless disposal
may permit unauthorized and improper use of the equipment. This may result in serious personal injury, injury
to third parties and pollution of the environment.
Most of the materials from which Hilti tools or appliances are manufactured can be recycled. The materials must
be correctly separated before they can be recycled. In many countries, Hilti has already made arrangements
for taking back old tools and appliances for recycling. Ask Hilti customer service or your Hilti representative
for further information.
