To Adjust The Clearance Between The Needles And The Lower Looper/Needle Guards; To Adjust The Clearance Between The Needles And The Fixed Needle Guard - Janome MyLock 744 Servicing Manual

Correct setting:
Both right and left needles should have an equal clearance from the front edge of the needle hoIes
on the needle plate.
The standard clearance between the Ieft and right needle and the lower looper is 0 mm to 0.05 mm.
The standard clearance between the needles and the rear needle guard is 0 mm to 0.2 mm.
The above standard clearance allows the needle to slightly touch the front needle guard.
To adjust:
1. Remove the looper cover unit, top cover unit, front cover unit, presser foot, needle plate and
needles.
2. Before loosening set screw C, attach the needle gauge #787-G02 to prevent change of needle
bar height during the adjustment.
Attach two #11 needles on the needle cramp and loosen the setscrew C. Adjust the two needIes,
to make the clearance between both needles and the front edge of the needle hole of the
needle plate equal by turning the needle bar in the D or E direction while pushing up the needle
bar to prevent change of needle bar height.
Retighten the setscrew C and remove the needle gauge.
