The Hook Carrier Guide should be adjusted so that the Hook Carrier travels freely in and out of the machine. The Guide must be tight enough to prevent lateral (front to rear) movement of the Hook Carrier.
Lateral movement can cause the Hook to miss the Needle and skip stitches.
To adjust the Hook Carrier Guide loosen the Lock Screw on the left end face of the frame above the Work Plate. After loosening the Lock Screw, the Guide can be tapped forward toward the front of the machine to tighten the gap between the Carrier and the Guide.
Turn the Hand Wheel over; if the machine feels tight tap the guide to the rear. Find a balance point between no lateral play in the Carrier and freedom of movement of the machine. Re-tighten the Lock Screw.
