AL-KO is the only manufacturer who has developed a special safety cable for the HE450S, which prevents accidental 'severing' of the wiring cable. The HE450S is lightweight and is ideal for small to medium sized hedges.

AL-KO Safety Technology: Safety Cable
The AL-KO Safety Cable is provided with a special cover, made of tough, flexible synthetic spiral hose, which has a large diameter. Therefore it cannot accidentally slip through the blade teeth, ensuring that the cable cannot be cut whilst in operation.
