Ryobi from Home Depot ... I realize it's a reverse thread.
Ryobi supples two wrenches and there seems to plenty
of torque. Still under return for 45 more days but I hate to
return an item this expensive because someone overightened
the nut at the factory. If I get the nut off will I have damaged
anything? ... I mean if the damage isn't obvious. Is there any
damage done from overtightening in the first place?

Always loosen a saw blade arbor nut in the same direction that the blade
spins.

So, being a left tilt saw, which this probably is, the threads are not
LH. My right tilt delta is reverse threads, or LH. My jobsite Dewally
is a left tilt and they thread on normally. Hey asphalt, you better
try righty-tighty lefty-loosy before you take it back brother.


Never mind left tilt vs. right tilt -- Leon nailed it with a simple rule:
whichever direction the blade spins, that's the direction you turn the arbor
nut to remove it. If you like, think of the saw teeth as directional arrows
showing you which way to turn the wrench.
