10 Disposal

CAUTION
Improper disposal of the equipment may have serious con-
sequences: the burning of plastic components generates toxic
fumes which may present a health hazard. Batteries may ex-
plode 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 equip-
ment. This may result in serious personal injury, injury to third
parties and pollution of the environment.
CAUTION
Dispose of defective batteries without delay. Keep them out of
reach of children. Do not attempt to open or dismantle batteries
and do not dispose of them by incineration.
CAUTION
Dispose of the batteries in accordance with national regulations or
return them to Hilti.
