27. Adjusting the feed timing
Warning: Turn OFF the power before starting the work as to prevent accident caused by abrupt start of the
sewing machine.
The feed timing can be changed by changing the stop position
of feed eccentric cam (1).
How to adjust the feed timing
1. Tilt the sewing machine head and loosen two setscrews (2)
in feed eccentric cam (1).
2. Turn feed eccentric cam (1) to change the feed timing.
Align graduation (3) on the feed bar driving arm with engraved
marker line (4) on the feed driving shaft.
Turn feed eccentric cam (1) in the direction of (+)
Increases the feed timing.
Turn feed eccentric cam (1) in the direction of (—)

28. Thread tension release releasing mechanism
Warning: Turn OFF the power before starting the work as to prevent accident caused by abrupt start of the
sewing machine.
By means of the thread tension release releasing mechanism, sewing can be performed without slackening the needle
thread tension even when the presser foot is lifted during sewing. (Even when the presser foot is slightly lifted at the thick
overlapped section by the knee lifter, this mechanism can prevent the thread tension from being changed.)
How to release
1. Remove the cap in the machine head and loosen thread
tension release changeover screw (1) using a hexagon
wrench.
2. Fix screw (1) on the top of thread tension release
changeover plate (2).The thread tension disk does not
rise even when the presser foot is lifted, and the needle
thread tension is not loosened. (The thread tension disk
rises only when thread trimming is performed.)
Caution: Do not use screw (1) at any position other than the
top or bottom position of the thread tension release
changeover plate. The screw has been factory-set to the
bottom position at the time of delivery.
