Hi,

WO doesn't sell tools, but they are readily avalable at hardware stores, Sears,
and hobby shops.

I recommend getting a set that is attached to a ring or to a handle. Search
for Hex Wrench set, or Allen wrench set, and then look for metric sets that go
all the way down to 1.5mm and they should include the sizes you need to make any
adjustments on the WO focusers. The WO focusers need to be adjusted by the
user in the field as needed, especially if you are going from warm to cold
environments. It's quite easy to do, and users shouldn't be afraid to do this
on their own, but if you drop one of these tiny hex wrenches and it isn't
attached, your are likely to lose it.

one. I bought several at a local hardware store in the "Little Drawers" section
for the two WO ZS 66SD I sold, and one for the one I am keeping. It goes in the
hole of the black thumb screw on the bottom of the focuser. Your instruction
manual will tell you how. But, the Black Thumb screw has to be TIGHT. Then,
using the 2mm Hex wrench, tweak the focuser to your preferance.
