Then,tighten the two screw . (1) 拉线钢丝的位置 安装拉线钢丝 时,请把挑线杆导向器 和钢丝前端的距离调整 为8-12mm,然后固定好固定螺丝 (2个)。 (2) Adjusting the stroke of the feeding wire 1) Increase the feeding amount of the needle thread if the needle thread fails to interlace with the bobbin thread or is likely to slip out of the needle eyelet at the start of sewing. 2) To increase the feeding amount of the needle thread,loosen the screw in the feeding stopper and move down the stopper. If the feeding amount of the needle thread is excessive,the thread will be likely to break. When the needle wire is not used Pull up the stopper knob,turn it counterclockwise and fit the top end of the knob in the hole located above the knob. 2) 把拉线量增大时,请拧松拉线挡块 的固定螺丝 ,向 下移动 调整。 注意 拉线量过大时,会容易发生短线现象 * 拉线钢丝不能动时 向上拉抬拉线挡块旋钮 ,左右转动让其前端进入上方的孔内 29. POSITION OF THE WIPER 拔线器的位置 WARNING: To avoid possible personal injury due to abrupt start of the machine,turn off the power to the machine and check to be sure that the motor has totally stopped rotating in prior. 注意: 为了防止突然启动造成人身事故,请关掉电源,请确认马达确实停止转动后在运行。 1) Align the red marker dot engraved on the amchine arm with the white marker dot engraved on the handwheel(the 2nd white marker dot in terms of the direction of rotation of the sewing machine). 2) Move the rod in the direction of the arrow,and adjust the clamping screw so that an approximate 2 mm clearance is provided between the top end of the needle and the wiper . 1) 把机臂的红刻点 对准手轮的白刻点 (缝纫机旋转方向的第二个 白刻点)。 2) 沿箭头方向转动杆 ,把针杆前端和拨线杆 的间隙调整为2mm左右 ,然后再紧固定螺丝 。 . 20. jintex.in
