2-3. Removal of Mechanical Parts
This section shows the disassembly procedure; to reassem-
ble, reverse the procedure. When reassembling, see that the
cables are not trapped and pinched by metallic edges (the
chassis, etc.) as wire restraints are used when routing or
dressing cables. When an E-ring or washer has been re-
moved, do not use it again.
2-3-1. Cautions in handling the mechanism ass‘y
1. Mechanism
A. When lifting the mechanism ass‘y, do not hold both
edges with one hand; hold the right and left edges of
the chassis with two hands.
B. Do not touch the head drum.
C. Do not apply force when installing the mechanism
ass‘y. After removing the mechanism ass’y, always
place it the right side up.
If it must be placed upside down for any reason,
place a protective sheet such as ‘bubble packing, etc.
under it to protect the exterior of the cassette holder.
D. Do not touch the tip of the flexible PC board. Also
do not pull or bend it strongly.
E. Do not lift the mechanism ass’'y by the flexible PC
board or leads.
F. Do not touch the guide roller with your bare hands.
To clean dirt or dust off the roller, wipe it gently with
a cotton swab moistened with alcohol.
G. Do not touch the portions of the posts which come
into contact with the tape. Do not scratch them with
tweezers, screwdriver, etc. and be careful not to touch
them with magnetized tweezers, screwdriver, etc.
H. Do not touch the rubber portions of the pinch roller
or belt and the felt portion of the tension band, etc.
with greasy fingers.
{. Do not touch the pulley over which the belt is peaked
with greasy fingers, etc.
J. When disassembling the mechanism ass’y, pay attention
to the following:”
(1) The counter torque when screw-locking compound
is not applied is maintained at 1 kg-cm or more;
therefore, be careful.
(2) If a screw secured with screw-locking compound
is removed, reapply the compound after reinstal-
ing it. Tightening screws with too much torque
may strip the screw threads; be careful.
K. When removing the coil spring, take care so that the
hook is not deformed.
L. When the head becomes dirty, use a cleaning tape.
