BEFORE STARTING A TASK:
-----------------------
Turn the CRANK to idle POSITION (see picture).
CLEAR the whole KEYBOARD by pulling the RIGHT LEVER on front.
  ( Single COLUMN is cleard with its COLUMN LEVER )
CLEAR the ARITHMETIC & COUNTER UNIT by
  o  LIFTING the CARRIAGE and ...
  o  ... PULL to the RIGHT: UPPER Handle & LOWER Handle
LIFT & SHIFT the CARRIAGE to the far left ( = POSITION 1).

ADDITION & SUBTRACTION:
-----------------------
Example:   123 + 45 - 6  =  162

ADDITION:  SET the LEFT LEVER to (+) and the SMALL RIGHT LEVER to (ADD).
Enter the first number (123) in the far right columns. Make a (clockwise
only!) turn with the crank to transfer the number into arithmetic unit.
The counting unit displays the figure 1. Enter the second number (45).
Make a turn with the crank to add the number. The arithmetic unit displays
the intermediate sum (168) and the counting unit displays the figure 2.

SUBTRACTION:  SET the LEFT LEVER to (-) Enter the third number (6).
Make a turn with the crank. The arithmetic unit displays the result (162)
and the counting unit is decreased by 1.

REMARK:     NEGATIVE RESULTS are displayed in the arithmetic unit
            as the COMPLEMENT of the next higher 10, 100, 1000, ...

            Example:   -12  =  99...9988

MULTIPLICATION:
---------------
Example:    123 x 45  =  5535

CLEAR counter and arithmetic.  SET the LEFT LEVER to (+)  and the SMALL
RIGHT LEVER to (MULT). Enter multiplicand (123) in the far right columns.
The multiplicator (45) has two digits, so the arithmetic unit is moved to
position 2 by  LIFT & SHIFT  the CARRIAGE.  Repeat making turns with the 
crank, until the first figure of the multiplicator (4) will appear in the
2nd position of the counter unit. Move the arithmetic unit by LIFT & SHIFT
to position 1. Repeat making turns with the crank, until the second figure
of the multiplicator (5) appears in the 1st position of the counter unit.
The multiplication is done: The multiplicand (123) stays in keyboard, the
multiplicator (45) in the counter unit and the result (5535) is in the
arithmetic unit.

DIVISION:
---------
Example:   22 : 7  =  3.1428  Remainder 4

Division requires 3 steps:

(A) To Set the Dividend into Arithmetic Unit:
    -----------------------------------------
    SET the LEFT LEVER to (-/:) and the SMALL RIGHT LEVER to (MULT).
    For the maximum number of decimals, LIFT & SHIFT the arithmetic
    to the far right position and ENTER the DIVIDENT (22) in columns
    6 & 5 of the ARITHMETIC with the affiliated conic knobs.

(B) To Set the Divisor in the Keyboard:
    -----------------------------------
    CLEAR COUNTER & INPUT unit.
    Enter the divisor (7) in the far right column.

(C) To Divide:
    ----------
    Make turns with the crank until the arithmetic shows an "underflow".
    SET the LEFT LEVER to (+), make a turn with the crank. SET the LEFT
    LEVER back to (-).  LIFT & SHIFT  the carriage to the next left
    position. Repeat this procedure until required number of decimals ...

    The result (3.1428) is in the counter unit ( in RED ), and the
    remainder (4) is in the arithmetic unit. The divisor (7) stays in the
    input unit, therefore an additional decimal can be estimated ...
    ( 5, cause 4 x 7 = 35).


R E M A R K S :
===========================================================================

This model is nicknamed "Travel T.I.M."
There are bigger "TIMs" with more
digits available; also with
" S h i f t - I n p u t "
instead of a Keyboard
see  T.I.M. III

     
T R A V E L I N G :   Reduce HEIGHT of the  »T.I.M.«  by removing the CRANK
---------------------------------------------------------------------------
  (1st)  Lift SPRING and PULL CRANK HANDLE radially to the rear ...
  (2nd)  ... STORE crank handle in space on LEFT SIDE under the CARRIAGE !

 

M I S S I N G   R U B B E R   F E E T   I N S T A L L E D ...
---------------------------------------------------------------------------
  (1st)  "SHOES" ON THE LEGS, if  »T.I.M.«  is switched IN UPRIGHT POSITION
  (2nd)  Rubber RINGS ( from GAS HOSE ), mounteded ON THE LEGS "SHOLDERS"
  (3rd)  Two Rubber BLOCKS as FEET, mounted ON BASE FRONT ...
