2. Numbers 0-11 on stitch regulating screw are for operator's

reference only.

FEED, NEEDLE LOOPER TIMING:

Set the first screw in operating direction of the feed drive eccentrics to be straight up, then, holding this position, set the needle bar at B.D.C.. Set the looper timing to the needles to be synchronized. Adjust the looper timing with the looper avoid drive sprocket.

NEEDLE ALIGNMENT:

Torque needle head to 14 to 16 in-lbs (1.6 to 1.8Nm).

Install the feed dog, needles and throat plate. Use the adjustable ferrules to align the needles in the throat plate and align the feed dog so it is centered side to side. tighten the throat plate support and ferrules in place.

LOOPER SETTING:

Use the right needle and looper to set the looper gauge. Set the looper gauge to 1/8" (3.2mm)when loopers at extreem right. Set the loopers front to back to deflect the needles forward .002" to .006" (.05mm to .10mm). set the looper avoid so the needle touches the back of the looper 2/3 down back as needles decend.

NEEDLE BAR SETTING:

Set the needle height so when the top of the needle eye is even with the bottom of the looper (on it's travel to the left) the looper tip is .020" (.5mm) past the needle. Use the left needle. Recheck looper setting. Torque needle bar clamp screw to the following specifications:

Torque needle bar@

18 to 20 in.-lbs. (2.0 to 2.3Nm)

REAR NEEDLE GUARD:

Set the timing of the rear needle guard so the guard reaches it's furthest travel forward as the loopers enter the scarfs on the travel to the left. Bring the looper tips to the center of the needles in the scarf. The tip of the needles should be 3/64" +/-1/64" (1.2mm +/-.4mm) below the top guarding surface. The guard should just touch the needles up to .002 (.05mm) deflection. The loopers when traveling to the left should just touch the needles to .002" (.05mm) clearance when entering the scarf area.

FEED DOG CENTERING AND HEIGHT ABOVE THROAT PLATE:

Set the machine to its longest stitch length. Center feed dog, front to back, so as to obtain equal clearance on the front side and back side of feed dog in the throat plate slots. Set the feed dogs to come out of the throat plate level. Set feed dog height to be full tooth at the rear when the feed dog is at the top of its stroke.

PRESSER FOOT:

Center the needles in the presser foot needle slots. The presser foot lifter lever stop should be set to when the foot is lifted it does not interfere with the needle head when the needle bar is down.

LOOPER THREAD TAKE-UP CAM SETTING:

The looper thread cam should be set so that the looper threads cast off the high lobe of the cam as the point of the needles are just even with the under side of the looper. Set the cast-off plate eyelets so that when the looper reaches its left end of travel, all of the looper thread is used and no thread is drawn from the cone. Move down for less. Set the retaining finger so that the finger is even with the bottom edge of its holder and the tip on the right side is touching the cast-off plate.

THREAD CONTROL:

Set the individual needle thread eyelets so they are 25mm below the top casting and to the extreme right when using the mount adapter.

PULLER ADJUSTMENTS:

With the roller resting on the top of the throat plate, the stop collar should be set about 15mm above the ledge of the puller casting where the stop screw rests. Set the stop screw to rest on the casting and lock in place. Set the lifter lever block to have 0.05mm to 0.15mm clearance above the lifter lever in the neutral position.

Note: When changing sprockets, if the total number of teeth on both sprockets is differentthan what was on the puller, check and readjust these settings.

Use the puller tension nut to add or remove pressure frm the roller.

PULLER ADJUSTMENTS CONT.:

When assembeling the puller to the machine, make sure that a minimum of .05 clearence is maintained between the roller and the throat plate step. Also the roller must sit flat on the throat plate.

Time the puller so the roller feeds at the same time the feed dog is feeding. When setting, both should be feeding at the same S.P.I.. Adjust the timing by using the sprocket on the upper main shaft in the arm.
