It's unusual for the power cord not to have a switch in it that will
let you turn the enlarger on and off. Using the red knob as a substitute
for the switch is likely to cause minute vibrations in the enlarger head,
which will degrade sharpness in the final print.

In the US, hardware stores sell switches that can be spliced into
standard two-wire power cords. I would assume that you could find
something similar in Italy. If you have any mechanical ability at all,
it's a very easy fix.

Ciao Beppe,

It is theorically feasible but I strongly advise you insert a switch in the power cord or, better,
buy a timer, a very simple one is enough.
You can find them very cheap on eBay, including pretty sophisticated timers (with analyzers which
may be somewhat to early for you as you're a beginner) at very low prices (50 Euros and less) on
eBay Germany.
Or ask the italian photo newsgroup (it.arti.fotografia), chances are someone close to you sells one.

Un salutone,

A timer is a most useful addition to any darkroom. If you get a Gralab 300
or equivalent you can use the same time for the enlarger and for timing
processing of you film developments. Very useful if you want consistent
repeatable results in the darkroom. If you didn't care about quality it's
unlikely you'd be posting here so I'd invest in a timer (or multiple timers,
I forget how many I own!).

That's exactly what the red filter is for. On many enlargers, this
filter
is on a small arm that swings in and out underneath the lens. I know
it's
build into the enlarger head on a Durst M600, and perhaps on some other
Durst models. This allows you to check the positioning of the easel
before exposure.
