    will the blade still wobble a bit after doing that? I pushed the button, inserted wrench then turned but the bolt moves slightly but never STOPS moving, and the blade still wobbles on the shaft.

Usually there is a button to press that locks the shaft arbor and then you use a wrench to tighten OFTEN is a left hand thread!

Check for lock button behind the blade guard toward the motor.

does this tool have a spindle lock? what I would try if not is putting the blade on a block of wood and using the drill and a socket adapter to loosen bolt, if appears from the picture that this might be a left hand bolt, this should take care of your problem.

How do I install the blade

you need to pull back the lower guard (remove battery first) and then start the blade at a slight angle until it goes into upper guard and then put on the spindle and reinstall the flange and blade bolt and tighten bolt till snug. You might try for a users manual or call them direct at 1-800-525-2579 and have them email a manual to you.

After removing the blade bolt and the outer flange you will need to fully retract the lower guard (remove battery) and sometimes wiggle the blade but it will come out.
