4. NEEDLE BAR
1. Needle bar crank position
Turn the handwheel ➎ and loosen the screw ➊ in the
needle bar crank ➋. Turn the handwheel until the
needle bar reaches the upper position. Pulley screw ➌
on the main shaft should be in the same line with
screw ➍. Tighten the screw ➊.
NOTE: The needle bar should be in the top dead
center position when the screw ➌ is at 12 o‘clock. To
check, turn the handwheel clockwise and counter
clockwise. The needle bar must move downward in
either direction. The needle ➓ makes its first stroke into
the right side of the throat plate.
2. The needle bar height adjustment
Adjust the needle bar ➏ height to 16 mm (5/8“) from
the surface of the throat plate ➐ to the lower edge
of the needle eye. Use height gauge ➒.
Loosen the set screw ➑ and move the needle bar up
or down as necessary.
