Page 10: Synchronizing Needle And Looper Motions
SYNCHRONIZING NEEDLE AND LOOPER MOTIONS NOTE: Needle and looper mechanisms are carefully synchronized with precision gauges before leaving the factory to insure the best possible sewing conditions. Should it become necessary to disassemble the main shaft or replace components of the needle or looper drive mechanisms, re-synchroniza- tion of the machine will be required to facilitate proper sewing adjust- ments. -
Page 11: Tightening Needle Head
TIGHTENING NEEDLE HEAD When replacement of the needle bar, and or needle head is neces- sary, torque the needle head to needle bar 14-16 in. lbs. (1.6-1.8Nm) or use torque rod No. 21227AR that has been supplied with the machine, for the purpose of eliminating the possibility of distorting the needle bar due to overtightening. -
Page 12: Setting The Looper Avoid Plain Feed
SETTING THE LOOPER AVOID PLAIN FEED If more or less looper avoid motion is required, remove cylinder side cover (A, fig 8) located at the lower front left side. For Plain feed use a screwdriver to loosen looper avoid link ball joint (B, fig 8) (for differential feed use TT-5 wrench to loosen looper avoid link screw C, fig 8). -
Page 13: Setting The Feed Dogs For Differential Feed (Cont.)
SETTING THE FEED DOGS FOR DIFFERENTIAL FEED (CONT.) If adjustment is necessary loosen screw (E, Fig. 11A) in feed dog support (C) and move as required. Retighten screw (E). The differential feed dog (A) may then be leveled with main feed dog (B). -
Page 14: Presser Foot And Presser Bar Adjustment
PRESSER FOOT AND PRESSER BAR ADJUSTMENT Adjusting or Replacing Presser Foot: Remove presser bar knob (A, Fig. 14) and spring (B). Loosen screw (A, Fig. 15) on presser bar guide (B). (Loosen screws (C) in upper stop collar for pneumatic machines only). Slide presser bar upward high enough to slip on presser foot yoke (E) with foot attached and tighten screw (F) on flat of presser bar. -
Page 15: Upper Feed Roller Adjustment (Cont.)
UPPER FEED ROLLER ADJUSTMENT (CONT.) When feed roller mechanism (C, Fig. 17) has been re- moved or replaced, .003" (0.08mm) minimum to .005" (0.13mm) maximum clearance should be maintained between roller and throat plate. To Adjust Guiding System for Roller: Loosen two screws (A). -
Page 16: Setting Needle Thread Take-Up And Frame Eyelet
SETTING NEEDLE THREAD TAKE-UP AND FRAME EYELET With the needle bar at the top of its stroke set the adjustable frame needle thread eyelet (A, Fig. 20) in the lower mounting hole of eyelet (B) so the needle thread from eyelet (A) to the needle lever thread eyelet (C) will be in a straight line. -
Page 17: Folder Adjustment
FOLDER ADJUSTMENT Slide folder (A, Fig. 22) on arm. The folder should be as close to the front of presser foot (B) as possible, making sure to avoid the presser foot contacting the folder when sewing across seams. If adjustment is necessary loosen screws (C) to move entire folder left to right or front to back as required. -
Page 18: Pneumatic Adjustments
PNEUMATIC ADJUSTMENTS Pneumatic settings can vary between different sewing applications. For best results set all air lines and air pressure settings as in (Fig. 25). If air lines are disconnected follow connection as in (Fig. 25). Air pressure settings should be set with air regulators as shown in (Fig. 26). Air lines should be attached with each end of line to corresponding letter (Fig. -
