Porter Cable Router help

[DNK]

Accidentally tossed the wrenches for my PC router.
Do I need 1 or 2? I can't remember.
I plan on getting this one at least.
Do I need another?

Depends on the model... 890 has spindle lock and needs one. 690 needs 2 wrenches since there is no spindle lock. I think most of the 3.25 hp models need 2 wrenches as well.

Thanks Ross.
