In case of the broken slit blade:
(a) Make a marking line before disassembly to
set the slit blade into the original position.
(b) Remove the slit blade set screws.
(c) First, whet the main blade. (Refer to the
illustration on the previous page.)
* Place the slit blade on the slit holder tool perpen-
dicularly and evenly and whet it uniformly and
horizontally. After whetting, remove burrs. When
removing burrs, be careful not to damage the slit
edge and scoop only the burred part lightly by
hand. After whetting, wipe off the machine oil
with ether and apply it thinly to the whetstone
again.
2. Stiffness and unevenness of the aperture/slit
change handle
If the aperture change handle has stiffness, uneven-
ness or play, remove the screws CR2×6SUS (2
pcs.), remove the cover (44770 2601), loosen the set
screws U2.6×2.5S (2 pcs.) of the aperture change
gear (40310 2518) and adjust the tooth clearance to
move smoothly.
