11) Adjusting feed cam
⑴ The adjustment of the feed cam body ① will determine the timing of the feed dog and the needle. Lay the machine back
and move the needle to its highest position. The standard position will be made when the baseline ② of the feed cam
body ① is aligned with the carved sign ③ on the bottom of the bed.
⑵ If the feed dog is faster than the needle, loosen the feed cam body fixing screw ④ and turn the feed cam body in the
arrow direction and then tighten the feed cam body fixing screw ④.
Turn it in the opposite direction to make the feed dog faster then the needle.
12) Adjusting feed dog height
Loosen the wheel feed dog clamp screw ① and the wheel feed dog driving gear clamp screw ② and move the wheel feed
dog fixing plate ③, the wheel feed dog ④, and the wheel feed dog driving gear ⑤ so that the upper side of the wheel feed
dog ④ is protruding about 0.8mm from the needle plate top ⑥. The clearance between the wheel feed dog ④ and the wheel
feed dog driving gear ⑤ is about 0.5mm.
