On a Drink Machine

氷なし、　先に押してください、　マークにはたらきます。
こおりなし、　さきにおしてください、　まーくにはたらきます。

のんだあとはリサイクル
After you drink, recycle (the bottle/ can)

Most vending machines have recycle bins next to them. Good luck finding a normal bin for your regular rubbish, though.

あったかい
Warm (thing)

On a vending machine. It's short for 暖かい　（あたたかい）. Again, it's used for warm things, as opposed to hot weather which uses 暑い　（あつい）.

つめたい
Cold (thing)

On a drink vending machine. This is used more for things, rather than　 寒い （さむい）　which is more used for weather.
