ADDO   MULTO - 13
Restoration Procedure



                  Back to the ADDO MULTO-13 Main Page ...

The ADDO  MULTO-13  came blocked. Someone had tried to "repair" and failed:
The 3 levers of the carriage were not in place -  The carriage's register
clearing was not synchronized ( it needs two pulls instead of one !) - The
BACK-TRANSFER INDICATOR had no function, because a spring was missing  -
And the "Counter-Finger" was bent ( It made noise in addition mode and in
subtraction mode it jumped 2-figures !)

My experiences "How to Start" ...

Flip the MULTO around. Under the carriage, right, lift the spring from its
post, fix it with a big paper clip on the twin-lever. Flip the MULTO back.
Remove the top-cover with 6 screws. Remove the bar in front of the carriage
with its 3 screws. Pull-out the carriage to the front.

Look at the bottom of the MULTO-13: Make sure, that the lever in the middle
is under its holder & forced by its spring! Remove the cover of the carriage.

CLEAN & OIL the MULTO.

Bring the carriage back in its "1" position: FLIP the MULTO !!! In this way
the 3 levers on the back side of the carriage are in their right position.
Hold the carriage and turn the MULTO upright again.  Use "Common Sense"  &
observe that the 3 levers are in place. ( See the detailed picture below !)
Replace the bar with the 3 screws, place the spring back on the carriage's
post. Make sure that all is OK ... Replace the covers in reverse order.

Here 2 DETAIL PICTURES ...

    

The (1st) picture shows the right positions of the three levers: The left
"grips" and the middle "touches" the top bar; the right "touch" the lower
bar.  The (2nd) picture shows (a) the added spring for the BACK-TRANSFER
INDICATOR - and (b) the gears for clearing the carriage's registers.  To
synchronize, the small tooth-wheel had to be shift right  ( against the
spring's force ), moved one tooth forward and released back in position.
