Chapter 10 Standard Adjustment 3. Adjustment of Clearance Between Needle and Rotary Hook 1. Turn the power switch off. o  q 2. Select the needle bar No. 1 q. The illustration at the left shows the case of BES- 960BC. For BES-1260BC, the No. 12 needle becomes 9. w e 3. Remove two flat screws w and dismount the needle plate e. 2mm 2mm r t i 0.3~0.5mm 4. Adjust the needle r and the rotary hook's t point so that they can put together at 2 mm above the needle bar lowest point (180˚) where the pulley indication mark "" and the stop mark "NH" are aligned. 5. Turn the rotary hook manually so that the point comes upward. 6. Loosen the set screw u on the side of the bed y. 7. Turn the eccentric screw i on the left side of the bed y using a regular screwdriver and adjust a clearance between the needle and the rotary shaft to 0.3 ~ 0.5 mm. u Note) Check that the needle bar height is 2 mm at this time. 8. Adjust the clearance between the needle and the rotary hook's point to 0.3 ~ 0.5 mm at the needle bar No. 9 o (No. 12 needle for BES-1260BC). Note) If the clearance between the needle and the rotary hook's point is not within the range of 0.3 ~ 0.5 mm, adjust again as described in step r until the clearance between the needle bar No. 1 or No. 9 (No. 12 for BES-1260BC) and the rotary hook's point becomes within 0.3 ~ 0.5 mm.

Adjustment of Clearance Between Needle and Rotary Hook
1.
Turn the power switch off.
2.
Select the needle bar No. 1
q
.
The illustration at the left shows the case of BES-
960BC. For BES-1260BC, the No. 12 needle becomes
9.
3.
Remove two flat screws
w
and dismount
the needle plate
e
.
4.
