Anyone here have a Woodpecker precision router lift V2 420 or 350 with a PC690 router?

Hi, folks -
Anyone here have a Woodpecker PRL-V2 420 or 350 with a Porter-Cable 690 router motor in it?
The descriptions say that above-the-table bit changes for the 690 require offset wrenches. I'm trying to determine if bit changes can be done with just one offset wrench for the lower nut, and a straight wrench for the collet nut itself.
Reason I'm asking is that I'm contemplating using a PreciseBits precision collet on the router, and the spanner wrench they supply is a straight wrench.
I emailed Woodpecker with this question and the response I got back from them was quite vague, so I'd rather find someone who can tell me from real experience what the deal is.
The reason I want to use the 690 instead of moving up to the 3HP 7518, which doesn't have the bit-change problem, is (1) cost: I already have the 690, and (2) power consumption.
Thanks, Tom Dacon
