Check the hammer rail hasn't gained a little rust, then polish it but only wipe the inside of the hammer. Then check the firing valve and spring.

Hi Rosie, how old is it, and does it still have the anti tamper in, if it does you will need the use of a pillerdrill or pop it round to local engineering shop to remove. kev Todd done a complete stripdown of S510 awhile ago, have a look, you should be able to find it, very easy to strip and rebuild, and of course Julian for seal kits etc. have fun.
