Control card Q1.7
in case of
exchange
New control cards are designed with two channels. Older
machines still have single-channel control cards.
It is an older machine, if the one knob has to be pressed con-
tinuously for the spindle to rotate.
This can be remedied by setting a bridge from pin c to pin e
on the new Q1.7 control card.
