If you have a brand new machine, chances are you don't have a major clog. It seems like you are using PLA. At 260C it will burn after a minute inside the nozzle, so you want to avoid doing that unless you are really desperate.
You might want to use the little white twist-ties that come with sandwich bags.
So:
1) Heat the nozzle to 220C.
2) While that is happening, remove the bowden tube from the print head
3) take a length (30cm) of PLA and straighten it out
4) by this time the nozzle is probably toasty, so insert the twist-tie into the nozzle. No need the strip the plastic off the wire, the hot nozzle will do that for you
5) Poke the twist-tie into the nozzle (use pliers) until it goes in around 4cm
6) Now carefully feed the short length of PLA into the nozzle and push down, you should get some PLA coming out slowly
7) If yes, it might require a fair bit of force, so push firmly until the blockage clears and the PLA runs quite quickly
Voila, nozzle unblocked. You can try this at 260C as well, but work quickly. Prepare everything in advance, and only then heat the nozzle up.

180C is hot enough to loosen filament enough such that you can stick a toothpick in it and remove it. But yes, 260C might help greatly - but only for a few seconds. More than 60 seconds and it slowly gets more premanently solid. For PLA I hate going over 240C. For ABS I don't like going over 250C unless things are moving. And if I print at 255C ABS and print slow - (say .1mm layers [less volume] and only 30mm/sec) then it will eventuall clog everything but if I print much faster (.2mm layers) it will be fine.
PLA is a little more forgiving than ABS. PLA is much easier to work with and print and PLA prints usually work better. But ABS is a great material also. I recommend most people stick with PLA for at least 100 prints before moving on to ABS. Also everytime you switch from ABS to PLA you are likely to have trouble with clogs. It's not worth the hassle if you can just stick to one material always.
yes. Very slowly and carefully.
