DISMANTLING AND DISPOSAL
The mechanical assemblies should be suffi ciently dis-
mantled for disposal as scrap metal.
No heavy metals or physical or chemical substances
harmful to health were used in the construction of the
strapping head.
The electrical assemblies should be dismantled so
that the mechanical, electromechanical and electronic
components can be disposed of separately.
The statutory regulations for disposal should be follo-
wed.
