(3) Remove the 2 screw of the printing unit. (4) Lift the printing unit. (Observe the gears connection !) (5) Lift the cover of the machine. HOW TO USE the BURROUGHS CLASS 8 ******************************** PRINT / NON-PRINT: ------------------ SET the SWITCH in front of the right ribbon to the RIGHT. ADDITION: --------- Everytime a number is entered and the handle is pulled, the number is added to the memory and printed when the PRINT-LEVER is in its RIGHT POSITION. ( LEFT Position = NO-PRINT = PAPER SAVING Option. ) RESET KEYBOARD: --------------- If a wrong figure is entered in a column, repeat with the right figure. To clear the keyboard: Push the ERROR Key. REPEAT: ------- To enter the same number more than once, press the REPEAT Key before pulling the handle. To release it, press the ERROR Key. SUBTOTAL: --------- The cumulated sum will be printed when the SUBTOTAL Key is pressed before pulling the handle. The memory will hold the actual sum. TOTAL: ------ The total sum will be printed when the TOTAL Key is pressed before pulling the handle. The memory will be cleared. ID-NUMBERS: ----------- An ID-Number can be entered and printed with the NON-ADD Key. This input is not registered in the arithmetic unit. SUBTRACTION: ============ For SUBTRACTION 9-Complement "Addition" has to be used.
