14 0. HOW TO USE THE OIN THRE COUNTER The machne detects the number of sttches. The preset value on the bobbn thread counter s subtracted n accordance wth the number of sttches detected. (Subtracton s made accordng to the settng of functon settng No. 7, bobbn thread count down unt.) When the value on the counter becomes a mnus value as " 0 - ", the buzzer peeps three tmes to warn the operator that the tme to change the bobbn thread has come. ) Press bobbn thread counter reset swtch to return the value ndcated on bobbn thread counter to the ntal value (t has been factory-set to "0" at the tme of delvery). The bobbin thread counter cannot be reset during sewing. In this case, make the thread trimmer actuate once. 3 ) Specfy an ntal value usng bobbn thread amount settng swtch 3. When keeping pressing the switch, the changeover speed s ncreased. < Initial value on the bobbin thread counter for reference > The table below gves the ntal settng values for reference when the bobbn s wound wth thread to the extent that the pnhole n the outsde of the bobbin case is reached as shown in the figure given above. Thread used Polyester spun thread #50 Cotton thread #50 Length of thread wound round the bobbn 36m 3m Value on bobbn thread counter 00 (sttch length : 3 mm) 000 (sttch length : 3 mm) Thread tenson rate 00 % ctually, the bobbin thread counter is affected by the material thickness and the sewing speed. So, adjust the ntal value of the bobbn thread counter n accordance wth the operatng condtons. 3) Once the initial value is specified properly, start the sewng machne. 4) When a mnus value s shown on the counter and the buzzer peeps three tmes, replace the bobbn thread. 5) fter the bobbn thread has been properly replaced, press bobbn thread counter reset swtch to return the value on the bobbn thread counter to the ntal value. Now, re-start the sewng machne. 6) If the remanng amount of bobbn thread s excessve or the bobbn thread runs out before the bobbn thread counter ndcates a mnus value, adjust the ntal value approprately usng the + or - swtch of bobbn thread adjustment swtch 3. If the remanng amount of bobbn thread s excessve Increase the ntal value usng the + swtch. If the remaining amount of bobbin thread is insufficient ecrease the ntal value usng the - swtch.. Uneven performance may occur in accordance with the winding way of thread or the thickness of materials and it is necessary to set the thread trimming amount with some surplus.. If the bobbin thread counter is used in combination with the bobbin thread remaining amount detecting device, the bobbin thread counter indicates the number of detections of the bobbin thread remaining amount detecting device. So, be sure to use the device after carefully reading the Instruction Manual for the bobbin thread remaining amount detecting device. - -

15 . HOW TO USE THE THRE TRIMMING COUNTER 3 obbn thread counter ndcaton can be changed over to thread trmmng counter (smplfed sewng counter) ndcaton by the operaton below. ) Functon settng No. 6 Turn OFF the settng of bobbn thread counter functon..

The machne returns to the normal moton. 4) Repeat the operaton ) to 3), and LE dsplay s turned to " " " ". Then, the functon of auto-lifter does not work. " " " " : uto-lfter devce becomes effectve. Selecton of the auto-lfter devce of solenod drve (+33V) or of ar drve (+4V) can be performed wth swtch. (Changeover s performed to drve power +33V or +4V of CN37.) " " " " : Solenod drve dsplay (+33V) " " " " : r drve dsplay (+4V) " " " " : uto-lifter function does not work. (Standard at the time of delivery) (Smlarly, the presser foot s not automatcally lfted when programmed sttchng s completed.). To perform re-turning ON of the power, be sure to perform after the time of one second or more has passed. (If ON/OFF operation of the power is performed quickly, setting may be not changed over well.). uto-lifter is not actuated unless this function is properly selected. 3. When " " " " is selected without installing the auto-lifter device, starting is momentarily delayed at the start of sewing. In addition, be sure to select " " " " when the auto-lifter is not installed since the touch-back switch may not work

21 . INITILIzTION OF THE SETTING T 3 ll contents of functon settng can be returned to the standard set values. ) Pressng all swtches, and 3, turn ON the power swtch. ) " " s dsplayed on ndcator wth a "blp" to start ntalzaton. 3) The buzzer sounds after approxmately one second (sngle sound three tmes, "blp", "blp", and "blp"), and the settng data returns to the standard settng value. o not turn OFF the power on the way of initializing operation. Program of the main unit may be broken. 4) Turn OFF the power swtch and turn ON the power swtch agan to return to the normal mode.. When you carry out the aforementioned operation, the neutral position correction value for the pedal sensor is also initialized. It is therefore necessary to carry out automatic correction of the pedal sensor neutral position before using the sewing machine. (Refer "0. UTOMTIC COMPENSTION OF NEUTRL POINT OF THE PEL SENSOR" p.8.). When you carry out the aforementioned operation, the machine-head adjustment values are also initialized. It is therefore necessary to carry out adjustment of the machine head before using the sewing machine. (Refer "5. justing THE MCHINE HE" p.3.) 3. Even when this operation is performed, the sewing data set by the operation panel cannot be initialized. 3. CHECKING PROCEURE OF THE ERROR COE ) Turn ON the power swtch wth swtch held pressed. ) The latest error number s dsplayed on ndcator wth blp. 3) Contents of previous errors can be checked by pressng swtch. (When the procedure has reached the end, two alarm sounds n sngle tone wll be heard, "blp" "blp".) - 9 -
