9 Disposal
WARNING
Risk of injury.

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.
▶
Dispose of defective batteries right away. Keep them out of reach of children. Do not disassemble
or incinerate the batteries.

Batteries that have reached the end of their life must be disposed of in accordance with national
regulations or returned to
