1. Unpacking Machine
Open packing box by carefully removing its cover so as not to damage the
machine or those of its parts which project from the top, such as the tension
parts.
Small accessory parts are packed separately in individual packages. Do not
discard any packing materials without prior scrutiny as to contents.
Clean from machine all greases, dirt or dust. Pay particular attention to area
around the looper me chanism and looper.
2. Setting-up Machine
Assemble knee lifter lever to machine and place on sewing table so that lever is
l 3m/m distant from front edge of the table. Line up belt groove in belt pulley of
handwheel with belt groove of drive mechanism(motor or clutch).
Mark three screw hokes for fastening machine to sewing table and place felt pad
under machine bed before machine is tightened down.
8. Handwheel Rotation and Speed
Turn handwheel only in direction away from operator for clockwise
rotation. Be sure motor drive is wired up to obtain the same clockwise rotation.
The recommended operating speed of a brand new machine is 1,800 to 2,000
stitches per minute. After a breaking-in period of several weeks and after the
operator has become skilled in the operation of the machine, the speed can be
increased up to 2,500 stitches per minute.
4. Oilling and Maintenance
It is important not to operate the machine before oil of good quality has
been filled in each and every oil hole along the top of the machine. When
breaking-in a new machine oiling should be done sparingly several times a
day. Thereafter, one oiling daily will be sufficient. After oiling, wipe machine
carefully to avoid soiling of the material.
