I stand to be corrected if I am wrong, but I think that the counterweight is locked with an allen bolt. If it is, then it can be loosened to allow fine adjustment for the cartridge of your choice.
I'm going off memory, so I might be totally wrong. Things get a bit hazy, sometimes, at my age!

The counterweight is indeed adjustable as is the cartridge position in the head shell and you must set these correctly. You should have got a protractor and plastic scales with the turntable. If not, you should buy the scales - they're not expensive - and print out one of the protractors that are freely available from vinylengine.
The_lhc, I strongly suggest you do the same. Unless you've struck lucky, you cartridge could be doing damage to itself, not to mention the vinyl you use it on. It is not correct to say you can slot a replacement cartridge straight in. The plus is that, when you have set it up correctly, the sound should be noticeably better.
The counterweight has a small screw holding it in place on mine, rather than an allen bolt but there's no markings on the arm to indicate what position it's in.
Anyway, the point of getting the 2M Red is that range of force it requires coincide exactly with the cartridge that was on there already and I checked with Henley when I bought the Red and they confirmed that.
And obviously I didn't just slap the cartridge in the headshell, I aligned it with a protractor from vinylengine, that was just a figure of speech. And the sound is massively better than before, if I'd just "slapped it in" there'd be obvious problems with the sound, and there isn't.
