1.  벨트  거는  방법  /  How  to  install  the  belt

 

 

  ★미싱을  뒤로  눕혀서  V벨트를  모터풀리②와  미싱풀리③에  걸어  주십시오.

      ★벨트의  장력은  출하시  적정한  장력으로  조정되어  있습니다. 

          어느  정도  사용하게  되면  V벨트가  풀리에  길들여져서  벨트의  장력이

          느슨해질  경우가  있으므로  벨트의  장력을  확인하여  주십시오.

      ★미싱의  회전방향은  풀리쪽에서  볼  때  좌회전입니다. 

          (시계반대  방향입니다.)

      ★벨트①을  손으로  눌려  13mm∼16mm  눌려질  정도로  고정나사④를 

          풀고  너트④을  돌려서  조절하십시오.

      ★  Tilt  back  the  machine  head  and  place  the  belt  ①  onto  the  motor

            pulley  ②  and  machine  pulley  ③.

      ★  Press  belt  ①  with  a  finger  (force  of  5  N), and  adjust  the  nut④  so

           that  there  is  a  deflection  of  13  to 16  mm.

Note:  ★  While  using  the  machine,  the  belt  will  conform  to  the  pulley    and  cause  the  belt  tension  to

                  loosen.  If  the  belt  tension  is  too  loose  the  following  faults  could  occur.

                      a.  The  stopping  position  may  shift,

                      b.  The  needle  bar  may  drift  when  the  machine  stops,

                      c.  An  extra  stitch  may  be  sewing  when  the  machine  stops,

                      d.  An  abnormal  noise  may  be head  due  to  belt  slipping,  and

                      e.  The  belt  may  become  too  loose  and  contact  with  the  cover.
