Earlier this week I bought from Homebase a mitre saw:

I had read reviews and seemed to fit my needs perfectly.
Got it home - and tested it. I found that when I started the saw, it tripped
my RCD on the supply. Tested it further - sometimes it tripped - sometimes
not. This was on initial start-up with no load.
Took it back - got a replacement.
The new one is just the same. About 1 in 10 of start-ups the RCD will trip.
The saw seems perfect for my needs - very accurate mitres and 90 degree cuts
are spot on - I think I will live with what for me is a minor problem - but
thought I'd just share.
