Notes:
• Pinch the tension band plate and tension arm
stud together and fix them. Be careful not to
bend the plate during the above. (See R in
Fig. 2.6.8 (2))
• The supply tension arm assembly has under-
gone perpendicularity management after be-
ing assembled, so when replacement is re-
quired, it will be necessary to replace the
entire mechanism assembly.
1) With the cassette housing removed, place the reel
in the mini-cassette position. (See Fig. 2.6.6 (2))
2) Manually rotate the emergency gear of mode mo-
A
tor counterclockwise (See section 2.2.2, "Mode
transition".) to perform loading untill the loading
end position.
3) Ensure that the right edge of the tension arm is
placed within the range of reference hole A on the
sub-deck.
4) If the right edge is not within the above range, ad-
just by turning the adjust pin.
