Resolving filament jam - Anycubic I3 Mega

Our new I3 Mega printed just fine until lately it seems to have gotten a filament jam. Normally on other printers I would take off the nozzle, take off the tubing, and hopefully be able to push the jammed material through. But on this printer it's really hard to see how to take off the tubing so as to get to the inside of the hot end. And I can't see the problem, it isn't in the translucent tubing. Does anyone have experience, or a good link or video, for how to do the necessary taking apart to clean out a jam?

Try printing with a higher temperature?
