9 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.
CAUTION
Dispose of defective batteries right away. Keep them out of reach of
children. Do not disassemble or incinerate the batteries.
CAUTION
Batteries that have reached the end of their life must be disposed of in
accordance with national regulations or returned to Hilti.
