Adjusting Backlash between Hook Drive Gear and LowerShaft GearThe rotary play of the hook should be 0.8 mm or less when the tip of the rotary hook iswithin the width of the feed dog as shown below.Adjust the backlash after the adjustment of the clearance between needle and rotary hook.

To check:1 Turn the power switch OFF2 Remove the extension table and bed cover.3 Loosen the Hexagonal socket screw (A). Jog the hook race with fingers to check the rotary play. If the play is larger than 0.8 mm or the gears do not turn smoothly, adjust the backlash as follows

Adjustment procedure:

1 Turn the Lower shaft bushing (Eccentric), in th direction of A when the play at rotary hook tip is too large.2 Turn the Lower shaft bushing (Eccentric), in the direction of B when the play at rotary hook tip is too small.

3 Tighten the Hexagonal socket screw (A).
