at a low speed (1000-1500spm) to check oil distributing condition through Oil Check Window (C). Perform
run-in operation at 1000-1500spm for 30minutes. After a lapse of one month of service during which the
working speed is increased gradually and the machine runs sufficiently well, the high speed 2000spm can
be adopted according to the nature of the work.
5) 调整旋梭供油量
Adjusting the lubrication of rotating hook
旋梭的油量，可以用油量调节螺钉 A 加以调节。顺时针方向（“+”号方向）转动油量调节螺钉 A，
油量增多；逆时针方向（“-”号方向）转动油量调节螺钉，则油量减少，油量调节螺钉 A 在回转 5 圈范
围内调节油量，拧向紧固位置时，油量最多，拧松转 5 圈时，油量最少。
The lubrication of the rotating hook can be
adjusted by Oil Adjusting Screw (A) as follows:
Turn Oil Adjusting Screw (A) clockwise (+) to
increase oil and turn Oil Adjusting Screw (A)
counterclockwise (-) to decrease oil. Oil Adjusting
Screw (A) adjusts oil amount within 5 turns.
When Oil Adjusting Screw (A) is fully tightened,
oil amount is maxi mum. Readjustment depends
on temperature, sewing speed and the like. In
practice, oil amount can be judged as follows:
remove the throat plate and place a piece of paper on instead, run the machine for about 20 seconds, then check
the oil splashed on the paper.
