Pole Base Assembly (supply or take-up side)
1, How to remove
{1} Remove the UV catcher 2 on the removal side by loos-
ening the screw (A).
{2} Remove the pole base assembly on the supply side from
the mechanism assembly by joosening the screw (B) on
the mechanism assembly back side and sliding the pole
base assembly toward the UV catcher 2.
(83) As far the pole base assembly on the take-up side, turn
the pulley of the loading motor to lower the cassette
holder because the screw (B) is hidden under the con-
trot plate. {See the "Procedures for Lowering the Cas-
sette holder assembiy" of 1.3 DISASSEMBLY/ASSEIV-
BLY METHOD.)
Further turn the motor pulley to move
the cassette halder until the screw (B) is no longer un-
der the contro! plate lin the half-loading position). Then
remove it as done for the supply side by removing the
screw (B).
NOTE: After reinstalling the Pole base assembly and the
joy catcher2, be sure to perform compatibility ad-
