13
TO ADJUST THE TIMING OF THE NEEDLE
AND THE FEED DOG
Correct setting:
When the tip of the needle is at 2 - 4 mm above the needle plate in its downward motion, and lowered
presser foot, the top of the feed dog teeth should be level to the top surface of needle plate at their
rearmost position.
Before adjustment, check if needle bar height and feed dog height are correct.

14
TO ADJUST THE TIMING OF THE NEEDLE
AND THE UPPER KNIFE
Correct setting:

Match the guide line on the balance weight with the one of the main shaft correctly.
Then tighten the two screws A.
: Turn the handwheel toward you by one complete turn, and recheck the needle and the
upper knife timing.
6:Attach the feed base cover.

15
TO ADJUST THE HEIGHT OF
THE LOWER LOOPER
Correct setting:
The height of lower looper is 65.7 mm from center of lower looper shaft as shown in illustration.
To adjust:
1: Set the upper knife in down position to loosen set screw A.
2: Turn the handwheel to get the lower looper in rightmost position.
3: Replace the lower looper.
4: Turn the handwheel to get the lower looper in leftmost position.
5: Insert the gauge downwards into the lower looper shaft as shown.
6: Loosen set screw A, and move the lower looper up or down to get the tip of lower
looper is in line with guide line of gauge.
7: Tighten set screw A.

You can adjust the height of lower looper without removing the lower looper thread guide.

16
TO ADJUST THE CLEARANCE BETWEEN
THE NEEDLE AND THE LOWER LOOPER /
NEEDLE GUARDS.
Correct setting:
The needle should have an equal clearance between the front edge of the needle holes on the needle plate.
The standard clearance between the needle and the lower looper is 0 mm to 0.05 mm.
The standard clearance between the needle 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 face plate unit, presser foot, needle plate and needle.
2: Before loosening set screw C, attach the needle gauge #787-G02 to prevent change of needle bar height
during the adjustment.
Attach #11 needle on the needle cramp and loosen the set screw C. Retighten the set screw C and
remove the needle gauge.
3: Turn the handwheel towards you to bring the tip of the lower looper from the left hand to the rear side of the
needle.
4: Loosen the hexagonal socket screws A on the front needle guard and open a space between the front
needle guard and the needle.
5: Next, loosen the hexagonal bolt B, and slide the lower looper unit to the front or to the back to adjust the
clearance between the needle and the lower looper.The clearance should be 0 mm to 0.05 mm.
6: Change the needle from #11 to #14.
7: Push the needle by the front needle guard to adjust the clearance between the needle and the lower
looper.The clearance should be 0 mm to 0.05 mm.
8: Turn the handwheel towards you to check the clearance between the needle and looper.
Make sure the front needle guard is touching the needle slightly and the rear needle guard is not touching
the needle.
9: Check the timing between the needle and the lower looper.
10: Recheck the needle bar height and the clearance between the needle and the lower looper.

17
TO ADJUST THE CLEARANCE BETWEEN
THE NEEDLE AND THE LOWER LOOPER /
NEEDLE GUARDS.

18
TO ADJUST THE CLEARANCE BETWEEN
THE NEEDLE AND
THE FIXED NEEDLE GUARD
Correct setting:

To adjust:
1: Remove the foot and needle plate and lower the needle to its lowest position.
2: Loosen the set screw A and adjust the position of the fixed needle guard.
3: Tighten the set screw A.
4: Attach the needle plate and the foot.

19
TO ADJUST THE POSITION OF
THE CHAINING FINGER
Correct setting:
When setting the needle plate setting knob to guide line S, chaining finger should be touch to side of needle
plate and tip of chaining finger should be same level to tip of needle on needle plate.

2: Make sure that the marking-off line on the upper looper drive cam is in line with the one on the main
shaft.
3: Loosen the hexagonal bolt, and adjust the distance between upper looper shaft guide and
bottom of upper looper.The dist ance should be 1.6 mm to 1.8 mm when the upper looper
is at the lowest position as shown in Fig. 1.
