Tensioners (2) and (3) are switched off with an electric magnet at

the foot automatic lifting. If the automatic foot lifting at the machine

stop is pre-selected, the tensioners are switched off, but

temporarily only, so that the switching off electric magnet does not

overheat.

Tensioners (2) and (3) are also switched off temporarily during the

trimming cycle.

–

Tensioners (2) and (3) are not switched off at the foot lifting with

the hand lever.
