F1 Rotary Reserve Switch

Hi.
Does anyone know how to use the switch for reserve fuel.
The notes are confusing to me. Apologies if I'm as sharp as a bowling ball but I have the switch currently flashing with low fuel. I have turned it off.

The notes say ...." When approx 4 litres of fuel remains, the float switch closes, switches off the pump and illuminates the the reserve switch light. Operation of the switch re-activates the pump: after refuelling, the switch will stay illuminated until turned off."

So, if I was riding the bike and ran out to 4 litres remaining it says the pump would switch off. ( Handy! Wouldn't the bike stop? )
My question is which position do I leave the switch on with a full tank of fuel? Is it the position it is on now with the light flashing?
I'm confused obviously. Do I begin with depressing the left side of the switch ( which now turns off the flashing light ) when the tank is full? At the moment the bike has the light flashing as the switch is pushed to the right, but the bike won't start.

I would love to know the correct proceedure.

Clear as mud!

I haven't seen the switch but it sounds to me that when the reserve light comes on you flick the switch (turn it on) and when you refuel it has to be put back where it was (turn it off).
Presumably the switch is lit from the time the float switch closes and the light is only reset when the manual switch is turned on then off again?

Makes sense. Will reset. Thanks

Your bike will run out of fuel at the most awkward time...
Press rocker switch & it should light up red..
It will take an age for the fuel to get through,
next time you fill up put the switch back to normal,light off.

Just to clarify,
The switch is not automatic,

Thanks. Now on to the overhas ating.appreciate everyones help. Cheers
