Changing stylus on JVC L-A31

I'll be getting a used JVC L-A31 tomorrow and it comes with a replacement stylus. I suppose ill be installing it right away as I don't know how old the one that is currently installed is. Any tips on how to make sure I don't break the tonearm or cartridge? I only replaced the stylus and cartridge once on a very cheap record player which uses one of those 3 euros cartridges, will the procedure be similar or should I expect some further complications?
