loose hammer

[ch0p1n 0wnz u]

hey

not the G closest to the middle C but the one above wont work, i took a look and when i hit the note the hammer is loose and goes to the lefthitting the metal bit and not the string, should i get someone to come tighten it, or is it easy to do yourself!since im only renting this piano i dont want to wreck anything (its a stupid old piano and i think i will just give it back anyway and save up for a good one, i always have a digital to practise on!
