While a 9/16" will work; Ego is metric, so you should use a 14mm if available.  9 / 16 = 0.5625 x 25.4 = 14.2875 mm (difference is 0.2875mm or 0.011")... um, never mind, use the 9/16" wrench. =)

I got the 9/16" wrench. I'll have to find time to use it. Thank You.

The blade is very easy to replace and I replaced mine with the high-lift blade for improved cutting/mulching and it made a huge difference. Good luck!
