4.5) Lubrication Adjustment of Hook
1. Checking the oil supply level of hook
A. After racing the sewing machine for three minutes (at an appropriate speed), secure the oil flow
checking paper as shown in Fig. 18 and run the machine for about five seconds. Then check the oil
tape marked on the paper.
B. Check the oil supply level three times. The appropriate level of oil is when the oil level neither
exceeds the maximum amount nor falls below the minimum level. (Insufficient oil would jam the hook,
whereas excessive oil would contaminate the sewing material with oil.)
2. Adjustment of the Oil Supply Level
Turn the oil flow adjusting screw (1) in the lower shaft front bushing in a clockwise direction for more
oil flow. Turn it counterclockwise for less oil.
(Fig. 18)
Turn off the power when adjusting the lower thread tension. If the operator
Caution mistakenly steps down on the pedal while switched on, the machine will
start automatically and can cause physical injuries.
When using the clutch motor, be aware that the motor will continue to rotate
for a while after the power is switched off. Start to work only after the motor
has come to a complete stop.
