Seam specifications 607-LSa-1. Components produce a .205" (5.2mm) wide seam. 36200UJ60 FLATSEAMER: Same as 36200UA52 except fitted with components to produce a .236" (6.0mm) wide seam. 36200UJE60 FLATSEAMER: For simultaneously trimming right and left plies and flatseaming knit undergarments, infants clothing and similar light to medium weight materials where closing elastic is required.
SAFETY RULES: 1. Before putting the machines described in this manual into service, carefully read the instructions. The starting of each machine is only permitted after taking notice of the instructions and by qualified operators. IMPORTANT! Before putting the machine into service, also read the safety rules and instructions from the motor supplier.
OILING Referring to Fig. 1, fill the machine at (A) and (B). Oil capacity of class 36200 is 2.5 ounces in the bottom reservoir and 2.5 ounces in the top reservoir. Use a straight mineral oil, Saybolt viscosity of 90 to 125 seconds at 100°...
ADJUSTING INSTRUCTIONS Instructions stating direction or location, such as right, left, front or rear of the machine are given relative to the operator's position at the machine unless otherwise noted. The handwheel rotates clockwise in operating direction. SETTING THE NEEDLE BAR HEIGHT & ALIGNMENT Insert the first (left) and fourth needles into the needle head.
SETTING THE NEEDLE BAR HEIGHT & ALIGNMENT (CONT) Correct spacing of the needles in the throat plate stitch tongue is imperative to proper sewing conditions. Improper relationship of the needles to the stitch tongue often results in malformed stitches. When replacing the stitch tongue make sure needles are aligned properly (see Fig.
SETTING THE LOOPER TRAVEL To adjust the looper travel remove the top front cover and the end cover. Loosen left-handed locknut (A, Fig. 7) and turn screw (B) clockwise to decrease the looper travel or counterclockwise to increase the looper travel. Tighten locknut (A) and recheck setting. NOTE: After setting the looper travel the machine must be checked for synchronization.
TIMING THE NEEDLES TO THE LOOPER (CONT.) Attach the looper clamp and height gauge (A, Fig. 9) to the heal of the looper by tightening screw (B). Turn the handwheel slowly in a clockwise direction until needle bar (C) touches stop screw (D).
LOOPER ADJUSTMENTS Looper Avoid The looper avoid is set at .094" (2.4mm). Using gauge no. 21227BV (A, Fig. 11), position looper shaft (B) fully to the rear (away from operator) and insert the gauge through the looper shaft hole in the end of the cylinder until the plunger is fully extended from the gauge.
LOOPER ADJUSTMENTS (CONT.) Looper Gauge Turn the handwheel in operating direction until the looper has trav- eled fully to the left. Loosen screw (A, Fig. 15) and move the looper holder to the right or left until the distance from the point of the looper to the center of the first (left) needle is 3/16"...
SETTING THE REAR NEEDLE GUARD Set rear needle guard (A, Fig. 18) so it touches the first (left) needle (B) but does not deflect. Check the guard position to the other needles to avoid pinching. Loosen screw (C) and reposition guard (A) as necessary. Tighten screw (C). SETTING THE STITCH LENGTH This machine is designed to sew 10 to 16 stitches per inch.
SETTING THE PRESSER FOOT (CONT.) Turn the handwheel in operating direction until link (A, Fig. 20) has traveled fully to the front. There must be a 1/64" (0.4mm) clearance between link (A) and the back of needle head (B) when link (A) starts to jackknife. Loosen screw (C) and rotate driving sleeve (D) to posi- tion link (A).
SETTING THE PRESSER FOOT (CONT.) The presser foot lifter stop plunger must be set so the cover thread hook will not hit the bottom of the needle head as the presser foot is being lifted. Position the needle bar to its lowest point of travel.
FIG. 28 SETTING THE TRIMMING KNIVES FOR BUTT SEAMING (STYLES 36200UA52, UAE52, UAK52, UJ60, UJE60, UX52, UX60) To make the adjustments for a flat, butt seam, position lower knife (A, Fig. 29) in the foot so it extends 1/32" to 1/16"...
SETTING THE TRIMMING KNIVES (ALL STYLES) (CONT.) If necessary loosen screw (A, Fig. 30) and move knife (B) to the right or left as required. Tighten screw (A). If the shear angle between the knives has to be changed, raise or lower screw (C, Fig. 30) in knife holder shank (D).
LOOPER THREAD ADJUSTMENT Loosen screws (A, Fig. 34) and position looper thread cast-off (B) flush with the right end of cast-off support plate (C). Tighten screws (A). Loosen screws (D, Fig. 34 inset) and time take-up (E) so the thread will cast-off when the needle bar has descended 7/64" (2.8mm) from its highest position.
HUNG FOOT ADJUSTMENT When sewing on extremely lightweight material and/or feed cutting is a problem, the presser foot may be "hung" by raising stud (B) until guide (A) rests on the shoulder of stud (B). This adjustment will raise the presser foot slightly, so only the pressure of the presser foot shoes contact the material.
