I just took delivery of my 802 on Friday, the baby of the family, but I think the 802,804 & 805 are pretty much the same, when it comes to the main body of the saws.
The motor is induction, and sticks out the back buy about a foot.
The foot print of my stand, which is the semi-enclosed type, different to the 804, is about 18" by about 24"
I haven't had an opportunity to play with it yet, only quickly put it together to make sure all the parts were there and the motor worked. But the riving knife slots behind 2 bolts attached to a bracket on the back. So atleast you don't need to undo the bolts completely, just slacken them.
The instruction manual, is not that good, or clear, basically its just a general overview, with some blurred pictures. Alot of the assembly parts, bolts, washers etc are different to those shown or described in the manual.
I purchased over the net, and woodford managed to completely get the delivery wrong. I did a post about this the other day"Beware Woodford Delivery". But one thing to be aware of is that their standard delivery is £82 incl VAT. Which to me seemed a bit pricey. Their june offer was to refund this, thats why I took the plunge, but I'm still waiting for the cheque!
Plus I sent them an email about their cock-up, they've not even had the courtesy to reply yet. All it would take is an apology, but most businesses don't seem to understand that is generally all it takes.
However from the very limited time I've had with it it seems a well made substantial piece of equipment, the blade height & tilt mechanisms are smooth. Howver one area which is a bit fiddley is trying to get the motor square and the pulleys lined up. It felt like I needed a couple of pairs of hands, as the motor is heavy. As someone previously on another thread pointed out, it alone weights more than my previous saw.
Time willl tell whether I made a good investment. Hope the above helps.
Cheers
