6-2. Precautions
(1) When replacing any part, always replace the cut washer that was
removed with a new one.
(2) This mechanism does not have control adjustment. If the control cannot
be set as required, clean and or replace parts.
(3) On the oil
a) Always use the specified oil. (Using another kind of oil can cause
various kinds of trouble.)
b) Always use clean oil, without any mixed-in dirt, to lubricate bearings.
(Using oil with dirt mixed in can cause the bearings to wear or to stick.)
c) One drop of oil is the amount shown in the Fig. 1, on the point of a pin.
(4) Perform circuit repair, tape running adjustment, etc. with the cassette
controller assembly attached to the mechanism.
(5) To operate the mechanical section alone, remove the FPC of loading motor
from the connector (section B in the Fig. 2), and apply voltage to the loading
motor to drive it. The voltage between terminals must be DC3V or less.
(Forcing the gears to turn by hand entails danger of breakage.)
(6) To install the cassette controller, push section A in the Fig. 2. Do not push
anything else.
(7) Do not deform any of the mechanical parts.
