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.
FLIP the MULTO !!! Hold the carriage in front of its "1" position: In this
way the 3 levers on the back side of the carriage are in their right position.
Slide the carriage into the body, hold it in place and turn the MULTO upright
again. Use "Common Sense" and observe that the 3 levers are in place. ( see
left picture below !) Replace the bar with the 3 screws, replace the spring
back on the carriage's post. Make sure that all works OK ...
Replace the covers in reverse order.
Here 2 DETAIL PICTURES ...
|
The (1st) picture shows the right positions of the 3 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.
