)可根据不同的缝纫工序需求进行增或减的微调整，但应注意不要增加
或减少过多。油量过少时会引起旋梭发热，油量过多时会污染缝料。
2）用油量测试纸测试3次，直至确认3次油量测试纸油迹均无变化为止。
3.Guide sample of oil mass adequacy
1) The guide sample shown in the right-hand figure(see Fig. 9) may be finely adjusted (
increased or reduced) as per different sewing processes; however, excessive increase or
reduction shall be avoided. Too little oil mass may lead to rotating hook heating, and over
much oil mass may lead to contamination of the sewing materials.
2)Test the oil mass 3 times using special oil mass confirmation paper till the oil traces in
-dicated by the special paper show no changes.
