Skin contact with these substances can have adverse
health effects.
WARNING Danger of poisoning
The soldering process can produce hazardous solder
vapours. Hazardous vapours and other aerosols may
be released when printed circuit boards are heated and/
or overheated.
Use a solder fume extraction unit.
•
Store your soldering tool in a safe place. When not in
use, units and tools should be stored in a dry, high or locked
area out of the reach of children.. Make sure that unused
soldering tools are free of voltage and de-pressurised.
The mains cable must only be plugged into the mains

ergonomically correct way. Avoid bad posture when using the
unit, as this can lead to postural problems.
The soldering tool must be operated only in perfect
technical working order. Safety devices must not be
deactivated.
Faults and defects must be repaired immediately.
Before using the unit / tool, safety devices must be carefully
checked to make sure that they are functioning properly and
in the manner intended. Check that moving parts are func-
tioning properly and are not sticking, and whether parts are
damaged. All parts must be correctly fitted and must satisfy
all the requirements necessary to guarantee troublefree
operation of the unit.
