I should also have mention, you'll need Precision Slotted (-) Screwdrivers, in 1.5mm, 2mm, 2.5mm, and 3mm.,
PBSwiss, Wiha, Kronos, and several sets of jewelers screwdrivers, both dedicated and with adapter bits,, are too thick as they come from the makers, (the PBSwiss I mention has the 'comfort handle, so their smaller traditional jewelers set MAY work, IDNK, but hope to find out for myself in the future), BUT the, Wera screwdrivers are perfect fits out of the packaging.
You can find these on Amazon, eBay, KC Tools, and I do no believe you should pay more than $5 of any of them, especially if you or a friend have PRIME, so shop around on-line for the best price, including free shipping.
The Wera drivers, except the 1.5mm, have extra long handles, and allow you to actually see what's happening beneath your hand, which is much better than the tiny 12mm or even 25,4 shafts of smaller jewelers tools, so do no think your looking at the wrong ones if you go looking; I'll post a pic in awhile.
You will also need a pair of good Tweezers, but in the $11 range you'll find what you'll need, with a C.H.P. 7 SA, (curved, fine point) and the same brand in the (very fine point) 3 SA.
Be careful to no over squeeze on a screw, etc, as these are generally well made, but common sense handling is needed to avoid malforming those tips.
I should have noted this on the previous post, but there is a small ball bearing in these shutters, (or More?) that you'll need to take extra caution when removing and putting aside.
I like the 1.5 (-) screwdriver for this, with my finger on top of the ball, when removing; have a secure container ready to put this in, right away, with a closed top.
If you do no have them, I suggest you get some PEC Pads, and, beyond cleaning glass, cut one og them in small squares, about 1cm/10mm, and if there is oil on your blades, take the curved tweezers, grasp all four (4) corners in the tip and wet with alcohol, then gently, brush aside the oil spots to remove any oil, including fingerprints.
There are other things you may want to add to your CLA kit, but for now, Isopropyl alcohol,97 - 99%, Hydrogen Peroxide, 3% and Finger nail remover (acetone) are your best tools, as is Naphtha, the Iso will clean and remove oils and, only when needed a tiny drop of remover on a reluctant screw/thread, will usually free it; DO NO FORCE ANY THREAD, like you might with a car or home appliance.
The Hydrogen Peroxide is for stubborn lens cleaning, particularly mold and haze, so have a soaking lid ready if you're going to do that, and the PEC Pads is the ONLY thing you should use for wiping/touching glass, Period.
I hope this will get you started or clear-up some questions you may have.
Be Well, Be Happy.
