Disclaimer for connecting 3rd party generator to customers pa system and other equipment.

Question

As above a charity has asked me to connect,for free a generator to their equipment for an outdoor presentation with 
 their PA system and a screen.They are supplying the generator,which I will be inspecting for suitability. 
 I was hoping to get them to sign a disclaimer on the lines of "Joe Blogs Electrical is not responsible for any damage 
 to equipment ,caused by use of the generator"Wondered if this sounds viable or better to walk away? 
 Regards,

I think I'd also be worried about damage to (or poor performance of the) equipment - traditional small generators aren't renowned for good voltage regulation, which while might not be an issue for conventional motor type loads, could be a bit more challenging for your more delicate electronics, especially things like the PA or projector which will likely have massive swings in demand as the sound/video images change. Likewise not all inverter generators are necessarily good with all switch mode type PSUs.

It's not entirely clear to me what the scope of your work is when you say 'connect' the generator (which you're not supplying) to some equipment (which you're also not supplying). Are they asking you to supply the distribution equipment/cabling between the two things they are supplying? 
 Would you issue documentation under BS7909 for the temporary system you're providing with a defined scope limitation. 
 As Simon says, think of how you might do it as a paid job and what's involved as if something goes wrong with a bit that you are 'responsible' for then consider the fact that there's a 100% discount may not help you very much?!

Then you have answered your own question! I do realise, however, that saying, "no" is usually much more difficult than, "yes". 
 I think that I would politely decline.
