4. Place gauge on needle plate and adjust height of needle bar so that needle "R1"
grazes the gauge.(Fig.2)
5. For the orientation of needle bar or needle holder, insert new needles in "L0 , L1
and L2", orientate needle bar so that the needles are centered in the needle plate
holes. Make sure that neither needle "L0 , L1 nor L2" is touching the inside of the
needle plate holes. Tighten screw "a" and recheck the height.(Fig.3)

and needle(s). If necessary, adjust clearance of chain looper (see page 11) and
clearnace of lower looper (see page 6).
