The serial number is stamped in the casting at the right rear base of the machine. CLASS DESCRIPTION High Speed, Feed-Off-The-Arm High Throw Machines, Two and Three Needle, Left Needle In Front.
ILLUSTRATIONS This manual has been arranged to simplify ordering repair parts. Exploded views of various sections of the mechanism are shown so that the parts may be seen in their actual position in the machine. On the page opposite the illustration will be found a listing of the parts with their part numbers, description and the number of pieces required in the particular view being shown.
Needle Type Description Sizes Available Short double groove, struck groove, ball eye, spotted, 080/032, 090/036, 100/040, 110/044, 125/049, 130GS government point, chromium plated. 140/054, 150/060 Table I NEEDLES Selection of proper needle size is determined by size of thread used. Thread should pass freely through the needle eye in order to produce a good stitch formation.
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.
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.
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).
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).
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.
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).
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.
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.
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.
ADJUSTING STOP COLLAR ON FEED ROLLER FOR PNEUMATIC MACHINES When feed roller machanism (A, Fig. 27) and/or puller shaft cylinder assembly (B, Fig. 27) has been removed or replaced, 1/64" (0.4mm) clearance should be maintained between upper connection (C, Fig. 27) and floating feed roller connection (D, Fig. 27) when feed roller mechanism is in up position. Turn off air supply to puller shaft air cylinder assembly (B, Fig.
