Adjustment Procedures
1) Loosen setscrews 1 and adjust so that throat plate support 2
should not come in single-sided contact but come in uniform
contact with throat plate 3 using setscrews 1.
1) Loosen setscrew 1 and press feed mechanism cover presser
2 in the direction of arrow.
2) Press feed mechanism cover 3 and tighten setscrew 1 so
that the feed mechanism cover should not rise.
(Caution) Check that feed mechanism cover 3 is pressed so
that it should not rise.
1) Close looper cover 2, loosen setscrew 3, and move looper
cover guide plate 4 back and forth until the looper cover is
brought to a position where the cover smoothly closes.
2) Move looper cover guide plate 4 until it slightly comes in contact
with looper cover receiving bracket 5. Now, fix the guide plate
by tightening setscrew 3.
Results of Improper Adjustment
™ If the throat plate support comes
in single sided contact with the
throat plate or does not come in
contact with it, the throat plate
will vibrate severely.
™ If the feed mechanism cover is
not fully pressed and the cover
rises, oil leakage will be caused.
