FEATURES : Easy Thread Trimming Timing Adjustment : Adjustment of the thread trimming is done simply by adjusting the position of the thread trimming cam relative to the lower shaft. There is no need to remove the timing belt and the timing between the needle and the rotary hook does not change, so there is no need for troublesome re-adjustment when the thread trimming timing is adjusted. Adjustment is easy even if the material or thread thickness changes, so that accurate thread trimming can be obtained. Low Noise and Low Viberation For Stress-free Operation : Using a highly-rigid frame and computer analysis that achieves balance between the main parts, its noise and viberation are minimized. In particular, the high-frequency noise from the rotary hook opener that is irritating to the ears has been greatly reduced. This reduces operator discomfort and alleviates stress. All possible measures to prevent the needle bar from falling out have been taken avoid damages to the sewing machine : if you accidently touch the stop lever (selection lever) during high speed sewing, you do not have to worry. The sewing machine is equipped with the safety mechanism which prevents the needle bar from falling out. Suuficient consideration for safety of sewing operation is given so that fatal damage to the sewing machine will be avoided. Quick needle bar select function reduces operator fatigue : One of the needle bars can be stopped simply by changing the position of the stop lever (select lever). Compared to the previous models, a stroke of the stop lever has been shortened to optimum stroke and the weight of the lever has also been reduced by about 10 % so that easy operation is possible with a light touch of the lever. The setting can be returned to twin needle sewing simply by pushing the push lever plate. The push lever plate can be removed from the front face of the sewing machine and easily replaced so that it can be adjusted to the best position. In addition, with the adoption of centre stop mechanism, the stop lever automatically and accurately returns to the centre position to prevent setting errors when it is set back to the twin needle sewing.
