How to repressurise boiler

[MissT]

Hi

I need to repressurise my oil boiler but cannot work out how to do it.

I am attaching pictures of the system.

Can someone please advise?

Thanks for help.

That black handle next to gauge, turn it a little, should hear water moving in and let gauge black arrow move to a little bit above the 1 mark. Then make sure handle is back off to as found position.

There may be a 2nd handle that needs opened at same time behind it on other end of that silver flexible pipe

Thankyou I thought it was that but it would not move, so I unscrewed it and put it back on and now it works!
