Operating Instructions

top pack (Model 41B) from a Model 42 Disc Drive, proceed as follows:
a. Place the top of the carrying case on the pack.
b. Turn the handle on the top of the case counterclockwise.
c. When the pack begins to turn freely, lift the case out of the compartment.
d. Holding the pack upside down, place the bottom of the carrying case on

To remove the bottom pack (Model 41A) from a Model 42 Disc Drive, proceed

a. Place the top of the carrying case on the pack.
b. Press the release knob on the top of the carrying case and then lift the
case out of the compartment.

CAUTION
Before lifting the cover to the disc pack compartment, check to be sure
that the START/STOP switch is in the STOP position and that the pack has
come to a halt. If the cover is raised while the pack is rotating, a locking
pin tries to extend into holes in the bottom of the pack and the pin could be
sheared off. If the locking pin is sheared off, the disc drive is unusable.
Never turn the POWER switch to the OFF position when the disc pack is
rotating. If the power is turned off when the read/write head mechanism
is extended from the wall of the drive, the heads could come in contact
with the disc pack recording surfaces causing permanent damage to the
pack. Always move the START/STOP switch to the STOP position and wait
for the pack to come to a halt before turning off the power.
