Adjusting The Level Feed Timing - Brother S-7300A Service Manual

7-5-6.

Adjusting the level feed timing

Normally this adjustment is not necessary.
・
The level feed timing relative to the needle movement can be changed using memory switches.
・
If the needle and feed timing (refer to "7-5-4-3. Adjusting the needle and feed mechanism timing ") has been changed,
・
carrying out this adjustment may solve problems that occur with the angle of the feed locus and the thread tightening.
・ In general, if the feed timing is delayed, upper thread tightening becomes easier.
(1)
1. While pressing the menu key (1), press the power switch
1093D
(2).
2. Change the value of memory switch No. 250.
If the value is increased, the feed timing will be advanced
relative to the needle, and if the value is decreased, the
feed timing will be delayed.
You can change the feed timing for special loci in the
same way using memory switch Nos. 251 to 253.
